V5.1 with RHEL / CentOS 8 Linux

 

This page explains how to install ]project-open[ V5.1 on RHEL/CentOS 8 64bit. Please see the discussion thread https://sourceforge.net/p/project-open/discussion/295937/thread/4b705d885c/  on SourceForge. 

VMware Virtual Machine

Installing ]po[ requires not only Linux expertise but also some time. As a shortcut, you can use our CentOS 8 virtual machine on http://sourceforge.net/projects/project-open/files/project-open/V5.1/ . This virtual machine has been built using the instructions below and has been exhaustively tested.

Please help us to improve below instructions. To report any bugs please use the SF Community forum . To get professional support please contact us . 

Base CentOS 8 Installation

Please download "CentOS-8.2.2004-x86_64-dvd1.iso" or higher and install with the option "Server with GUI".

After a reboot, login as root and configure the network if you haven't done this before already:

  • nmtui
    set the host name to "po-v51"
  • nmtui
    setup an network connection: "Edit a connection", select an ethernet interface, edit the configuration, select "Automatically connect" and quit.
  • systemctl restart network-online
    in order to restart the network manager
  • yum -y group install "Graphical Administration Tools" --setopt=group_package_types=mandatory,default,optional 
    in order to install system administration tools 

To verify network connectivity try to ping some external server, for example:

ping www.google.com

Enable Extra Repositories EPEL and PowerTools

Execute as root:

yum -y install epel-release
yum -y install dnf-plugins-core
yum -y config-manager --set-enabled PowerTools

VMware Guest Tools

When running CentOS as a VMware virtual machine please install the VMware guest tools:

Execute as root:

yum -y install open-vm-tools

Optional: Gnome Dash to Panel

For personal taste, I tend to install "Dash to Panel":
With Firefox in CentOS 8 navigate to https://extensions.gnome.org/extension/1160/dash-to-panel/ , enable/install the Firefox Gnome extension and switch on the blue button on the top right.
As an alternative, go to CentOS 8 Settings and choose: Software -> All -> Search -> "Dash to Panel". Then click on "Extension Settings" to review. I usually set Style -> Panel Size to 32.

Tools

]po[ will need a number of tools for creating systems integration interfaces.

yum -y group install "Development Tools" --setopt=group_package_types=mandatory,default,optional
yum -y group install "System Tools"
yum -y install vim emacs-nox
yum -y install cvs svn git wget libXaw expat expat-devel pango graphviz
yum -y install openldap-clients openldap-devel mlocate psmisc

Perl Libraries

]po[ uses Perl for integration with several external applications:

yum -y install perl perl-Archive-Tar perl-Archive-Zip perl-CGI
yum -y install perl-CPAN perl-CPAN-Meta perl-CPAN-Meta-Requirements perl-CPAN-Meta-YAML
yum -y install perl-Carp perl-Compress-Raw-Bzip2 perl-Crypt-OpenSSL-RSA
yum -y install perl-Crypt-OpenSSL-Random perl-DBD-Pg
yum -y install perl-DBI perl-Data-Dumper perl-Digest-MD5
yum -y install perl-Encode perl-File-Slurp perl-GSSAPI perl-IO-Socket-IP perl-IO-Socket-SSL
yum -y install perl-JSON perl-LWP-MediaTypes perl-LWP-Protocol-https perl-Net-DNS
yum -y install perl-Net-HTTP perl-Net-SSLeay perl-Params-Check perl-Params-Util
yum -y install perl-Socket perl-TimeDate perl-YAML perl-core perl-devel
yum -y install perl-libs perl-libwww-perl rrdtool-perl perl-YAML

Install OpenOffice/LibreOffice

]po[ PDF generation functions use OpenOffice "headless" in order to convert ODT templates to PDF::

yum -y install libreoffice-headless

Disable SELinux

At the time of writing (2020-11-10) there are issues with SELinux blocking certain operations of ]po[.

Previous versions of ]po[ were able to work together with SELinux, so this is probably a temporary issue.

To disable SELinux please edit the /etc/selinux/config as root and set:

SELINUX=disabled

You need to reboot your system with "reboot".

Disable Virtualization

We won't need the virtualization features, so we can disable it:

systemctl stop libvirtd
systemctl disable libvirtd

You need to reboot your system with "reboot" in order to activate the change.

Optional: Setup ]po[ custom Background

We want to add a ]po[ logo to the CentOS 8 background. Create modified versions of the PNG files referenced in /usr/share/backgrounds/c8/default-hue-6.xml and save them in /usr/share/backgrounds/po/. Here is a tar with the po-background.tgz  modified images and here is how the <file> section of default-hue-6.xml should look like afterwards:

<file>
    <!-- Wide 16:9 -->
    <size width="1920" height="1080">/usr/share/backgrounds/po/po-tv-wide.png</size>
    <!-- Wide 16:10 -->
    <size width="1920" height="1200">/usr/share/backgrounds/po/po-wide.png</size>
    <!-- Standard 4:3 -->
    <size width="2048" height="1536">/usr/share/backgrounds/po/po-standard.png</size>
    <!-- Normalish 5:4 -->
    <size width="1280" height="1024">/usr/share/backgrounds/po/po-normalish.png</size>
</file>

Setup user "projop" and environment

As user "root", please create a new group and user "projop":

mkdir /web
groupadd projop
useradd -m -g projop -d /web/projop/ projop

Include the user "projop" in group "wheel" in order to allow projop to become root via "sudo su -":  Edit /etc/group and add the user "projop" in the line with group "wheel":

wheel:x:10:projop

Edit /etc/profile to add a few personal shortcuts:

alias "l=ls -als"
export EDITOR=emacs

Edit /web/projop/.bashrc and add the following lines:

alias "l=ls -als"
export EDITOR=emacs

# Include the hostname (project-open-v51 by default) in /etc/hosts as localhost or with it's fixed IP (if it has a fixed IP...):

127.0.0.1 localhost project-open-v51

Download and Install ]po[

Please login as user "projop" and download the installer-linux GIT repo:

su - projop
git clone https://gitlab.project-open.net/project-open/installer-linux.git
cd ~/installer-linux
mv * ../
mv .ba* ../
mv .gi* ../
mv .pg* ../
cd ~
rmdir installer-linux

]project-open[ consists of >200 "packages" that reside in the ~/packages/ folder. Please execute as user "projop":

su - projop
cd ~/packages
bash ~/bin/git-clone-vanilla

The git-clone-vanilla.sh will use GIT to clone about 120 standard packages that together make up the ]project-open[ product.

Install NaviServer

As user "root" copy the NaviServer from the installer in ~projop/ns/ to /usr/local/ns/:

su - 
cd /usr/local
mv ~projop/ns .
chown -R root:root /usr/local/ns

Setup PostgreSQL 10

PostgreSQL 10 is part of CentOS 8.2. Please only use 10.x (with x >= 15). Other versions of PostgreSQL will produce errors.

Please install the database as user "root" using:

yum -y install postgresql postgresql-server postgresql-contrib postgresql-devel postgresql-odbc postgresql-docs

Initialize and start the database:

/usr/bin/postgresql-setup --initdb --unit postgresql
systemctl start postgresql

Configure PostgreSQL startup:

systemctl enable postgresql

Create a new database user "projop" and the corresponding database:

su - postgres -c "createuser -s projop"                             # new database user "projop" with admin rights
su - postgres -c "createdb --encoding=utf8 --owner=projop projop"   # new database

You can verify your PostgreSQL installation by typing:

su - projop -c psql

Enter "\q" or press Ctrl-D to exit.

Now import the database dump as user "projop"

su - projop
gzip -d ~/pg_dump.vanilla.sql.gz
psql -f ~/pg_dump.vanilla.sql > import.log 2>&1

The import can take up to a few minutes, depending on your system. Please ignore the ~3.500 error messaging showing up at the beginning (that's because the dump contains instructions to drop any data that's left in the DB...). You can also ignore any error messages containing a "$libdir/tsearch2". In order to verify the import please execute:

su - projop
psql -c "select count(*) from users;"

.. which should return "197".

Optional: PostgreSQL Performance Optimization: Edit the "postgresql.conf" configuration file in /var/lib/pgsql/data/ as user "postgres":

  • listen_addresses:
    Please choose between 'localhost' or '*':
    • 'localhost' is the safe option, meaning that the PostgreSQL is only visible for the processes running on the server itself.
    • '*' means that users on other computers may access the database. You need to enable this if you want to connect to the DB via pgAdminIII, or if you want to integration ]po[ with some other systems. In this case you also need to edit the pg_hba.conf in the same folder. Please see the PostgreSQL documentation for details.
  • max_connections:
    • 100 for the VMware appliances for two ]po[ instances ("projop" and "stage"), as each ]po[ instances opens a number of connections during startup.
    • 500 for SaaS production servers
  • shared_buffers:
    How much memory should PostgreSQL get? PG experts recommend between 1/6th and half of the available RAM for high-performance production systems.
    • 128MB - We use this value for the default ]po[ virtual machine, because it may run on only 1GB of RAM.
    • 16384MB - This is the value used in our SaaS production servers with 64GB RAM.
  • work_mem:
    Please see this blog on PG performance .
    We set it to 64MB on production servers up from 64kB, because of potentially large lists of data to be sorted.
  • maintenance_work_mem:
    We use 256MB, if there are >= 2GB of RAM
  • timezone and log_timezone:
    Please set to your timezone. We use 'Europe/Madrid' for the VMware appliance.
    Changing the time zone during production operations will lead to duplicate entries when logging hours and offsets in task start- and end dates in the Gantt Editor. 

You need to restart the database as root in order to activate changes:

su -
systemctl restart postgresql

Edit the ]po[ configuration file

Please modify ~/etc/config.tcl as user "projop" and check/modify the following parameters:

set httpport     8000
set hostname     "project-open.yourdomain.com"
set servername   "\]project-open\[ V5.1 for YourCompany"

You can also modify the http port if you know what you are doing. Please note that the port number has to be above 1024 for permission reasons.

Open the Firewall Port 80, 443 (and 8000)

The firewall is enabled by default in CentOS 7, so we will have to punch holes for the ]project-open[ ports 80, 443 and 8000 graphically using system-config-firewall-tui or manually:

su -
firewall-cmd --add-port=80/tcp --permanent
firewall-cmd --add-port=443/tcp --permanent
firewall-cmd --add-port=8000/tcp --permanent
firewall-cmd --reload

Port 8000 is the direct access to the NaviServer. This port is normally not exposed directly to the user, but only via a reverse proxy. So opening this port is optional, but may be interesting if you are running a reverse proxy (NGINX, Pound) on a different system (Web application firewall, ...) that exposes the service to the end user.

Start ]project-open[ Manually

As user "root":

/usr/local/ns/bin/nsd -f -t /web/projop/etc/config.tcl -u projop -g projop

]po[ should take a few seconds before the line appears "[...] Notice: nssock: listening on 0.0.0.0:8000".

As a result, you should be able to see 8000 in the list of ports accepting connections:

netstat -nlp | grep 8000

Please point your favorite Web browser to http://localhost:8000/ and login as "sysadmin@tigerpond.com" / "system". You should see a login page (default admin: "sysadmin@tigerpond.com" / "system") or a configuration wizard. Please do not continue here at the moment, because we still need to fix several issues before ]po[ will run as desired.

You can stop the ]po[ server in the terminal window using Ctrl-C.

Congratulations, great job!

Automate NaviServer Startup

We now have to automate the startup of NaviServer (the application server of ]project-open[) for production use:

Create a new file /usr/lib/systemd/system/po@.service with the following content: 

[Unit]
Description=Project Open as user %I
After=postgresql.service network.target
Wants=postgresql.service
[Service]
Type=forking
PIDFile=/web/%i/log/nsd.pid
ExecStartPre=/usr/bin/rm -f /web/%i/log/nsd.pid
ExecStart=/usr/local/ns/bin/nsd -t /web/%i/etc/config.tcl -u %i -g %i &
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s 9 $MAINPID
Restart=always
KillMode=process
[Install]
WantedBy=multi-user.target

Please execute the following commands in order to activate the configuration:

systemctl daemon-reload
systemctl enable po@projop
systemctl start po@projop

You can check if NaviServer is running by monitoring it's error file (debugging is switched on by default):

tail -f /web/projop/log/error.log

Install NGINX

]project-open[ by default listens on port 8000. We install NGINX as a reverse proxy to listen on ports 80 and 443, handle SSL and redirect to port 8000. Ngnix is also convenient if you want to run more then one ]po[ on your machine, allowing to route requests to multiple back-ends.

In order to install nginx we need to enable the "epel" repositories with experimental software for CentOS: 

yum -y install epel-release
yum -y install nginx

Please paste the following into /etc/nginx/nginx.conf (remove any existing "server" configuration):

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
events {
    worker_connections 1024;
}
http {
    log_format   main  '$remote_addr - $remote_user [$time_local] "$request" '
                       '$status $body_bytes_sent "$http_referer" '
                       '"$http_user_agent" "$http_x_forwarded_for"';
    access_log          /var/log/nginx/access.log  main;
    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    types_hash_max_size 2048;
    default_type        application/octet-stream;
    include             /etc/nginx/mime.types;
    include             /etc/nginx/conf.d/*.conf;

    # Increase timeout for slow pages to 10 minutes
    keepalive_timeout    601;
    proxy_send_timeout   601;
    proxy_read_timeout   601;
    fastcgi_send_timeout 601;
    fastcgi_read_timeout 601;
}

Add a drop-in for your server in /etc/nginx/conf.d/projop.conf:

server {
    listen 80 default_server;
    listen 443 ssl default_server;
    # Uncomment in order to respond only to one specific server name:
    # server_name project-open.*;
    # Redirect to back-end server via HTTP
    location / {
        proxy_pass           http://127.0.0.1:8000;
        proxy_set_header     X-Forwarded-For $remote_addr;
        proxy_set_header     Host $host;
        client_max_body_size 1024M;
    }
    # RSA certificate
    ssl_certificate /etc/nginx/certificates/fullchain.pem;
    ssl_certificate_key /etc/nginx/certificates/privkey.pem;
    # Handle errors
    error_page    500 502 503 504 /err/50x.html;
    error_page    404             /err/404.html;
    location /err/ {
        root /etc/nginx/html;
    }
    location /.well-known/ {
        root /etc/nginx/html;
    }
    rewrite_log on;
    # Redirect non-HTTPS traffic to HTTPS
    if ($scheme != "https") { return 301 https://$host$request_uri; }
}

Create a self-signed certificate (you may later replace this by a certificate from Let's Encrypt or similar):

mkdir /etc/nginx/certificates
openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout /etc/nginx/certificates/privkey.pem -out /etc/nginx/certificates/fullchain.pem

Now OpenSSL will ask you about the data of the certificate. Here we will use the following example for a certificate supposed to be for ]project-open[ Business Solutions, S.L.:

  • Country Name: ES (for Spain)
  • State of Province Name: Catalonia
  • Locality Name: Barcelona
  • Organization Name: ]project-open[ Business Solutions, S.L
  • Organizational Unit Name: <empty>
  • Common Name: project-open-v50.project-open.net
  • Email Address: info @project-open.com

Start NGINX and configure to automatically startup:

systemctl enable nginx
systemctl start nginx

You should now see nginx listening on ports 80 and 443:

netstat -nlp | grep 80
netstat -nlp | grep 443

Optional Let's Encrypt Server Configuration

Let's Encrypt provides you with free SSL certificates, if your ]po[ server is directly accessible from the Internet.

]po[ is designed to work directly in the Internet, and even large corporations use ]po[ this way. However, such a configuration requires a support contract  in order to keep ]po[ updated if security issues appear.

Install certbot:

yum -y install python3-certbot-nginx

The following line should be sufficient If your server is accessible from the Internet:

certbot --nginx -d project-open.your-domain.com

For more options please see the certbot documentation .

Optional SELinux Configuration

Tell SELinux to allow nginx to create an outgoing connection to port 8000:

Point your browser to http://localhost:80/ in order to cause a "502 Bad Gateway" error (it is important to cause this error!). Please check your firewall configuration if you don't get a "502" error.
Then execute the following commands:

cat /var/log/audit/audit.log | grep nginx | grep denied | audit2allow -M mynginx
semodule -i mynginx.pp

Now point your browser again to http://localhost/ and you should see ]po[ in action.

Configure Automatic Backups

You can automate a daily ]po[ backup using our export-dbs script. Please copy the script (please follow the link for source code) into the file /root/bin/export-dbs. Mark the script as executable, create default backup directories and execute the script:

mkdir /var/backup                                             # create a global backup directory
chown projop:postgres /var/backup                             # allow projop & PostgreSQL to write backups
chmod g+w /var/backup

mkdir /var/log/postgres                                       # create directory for DB related logs 
chown postgres:postgres /var/log/postgres                     # allow projop & PostgreSQL to write chmod g+w /var/log/postgres
chmod ug+x /root/bin/export-dbs                               # mark backup script as executable
perl /root/bin/export-dbs                                     # execute backup script manually for testing

Automate the backup by adding the following lines to your crontab:

29 3 * * * /usr/bin/perl /root/bin/export-dbs > /var/log/postgres/export-dbs.log 2>&1
24 3 * * * /usr/bin/find /var/backup -name '*.tgz' -mtime +6 | xargs rm -f
25 3 * * * /usr/bin/find /var/backup -name '*.bz2' -mtime +6 | xargs rm -f

n action.

Other Crontab Activities

ToDo: Copy crontab from reference servers

Fix GraphViz Configuration

GraphViz creates GIF and PNG images from textual descriptions. ]po[ uses GraphViz to visualize the state of workflows and similar purposes.

To fix/enable GraphViz, please create a symbolic link for the "dot" tool:

cd /usr/local/bin/
ln -s /usr/bin/dot

If you should get an error saying "gif is not supported" or similar, then you will have to install the GD extension of GraphViz:

cd /usr/src/
wget http://mirror.centos.org/centos/8/PowerTools/x86_64/os/Packages/graphviz-gd-2.40.1-40.el8.x86_64.rpm
rpm -i graphviz-gd-2.40.1-40.el8.x86_64.rpm

We have made a copy  of this RPM in case it should disappear.

Install and Test "Postfix" Email Server

]po[ by default uses Postfix to send out notification emails. To install please use:

yum -y install postfix postfix-perl-scripts mailx

You can test your email configuration by sending out a test email to yourself:

echo "test email body" | mail -s "Test Email Subject" <you@your_domain.com>

Then have a look at the last lines of /var/log/maillog

tail -n 20 /var/log/maillog

You may have to configure a Postfix "relayhost" pointing to your corporate SMTP server or similar.

For a development server you may want to configure a local delivery of all email to the local root account for debugging purposes.

In this case please edit your /etc/postfix/main.cf and add the following three lines:

luser_relay = root@localhost
local_recipient_maps =
mydestination = pcre:/etc/postfix/mydestinations

Then create the file /etc/postfix/mydestinations and add a single line:

/.*/      ACCEPT

Then restart Postfix using systemctl restart postifx .

(The solution was taken from this discussion thread .)

Enable ]po[ Integration Links

]po[ includes a long list of integration links with external systems including Microsoft Active Directory, SAP FI, SAP PS, Microsoft Navision NAV, SQL-Ledger, SugarCRM, vTiger, Atlassian Jira, TaskJuggler, OCS Inventory NG, CVS, SVN Subversion, Git, Email, and others. Most of these integration links use Perl and Perl libraries as interfaces. Therefore you will need to have working versions of a number of Perl modules installed on your system.

There are two steps necessary in order to install these Perl libraries:

Install Most Perl Libraries via YUM

Most Perl libraries are available from the standard CentOS and "EPEL" repositories as RPMs and installable via YUM. First you need to add the EPEL repositories, if you didn't do this already:

yum -y install epel-release

After that, you can install additional Perl packages:

yum -y install perl-MIME-tools
yum -y install perl-Path-Class
yum -y install perl-IO-Socket-INET6

Install Missing Perl Libraries via CPAN

Finally, you will have to manually compile and deploy some Perl libraries that are not available as part of CentOS for whatever reasons.

So we will have to pursue a somehow dirty method here and install the additional Perl packages in system folders that are managed by YUM. In order to do so, we will need to configure CPAN to use the system folders.

1. Cleanup any files from previous installations

  • delete /root/.cpan
  • delete /root/perl5
  • edit /root/.bashrc/ and check and remove any PERL environment variables
  • logout and login again
  • execute "set | grep -i perl" to check that no environment variables are set 

2. Start CPAN as user "root":

cpan

  • Answer "no" to the first question ("Would you like to configure as much as possible automatically?") in order to enter into manual configuration. 
  • Answer <enter> to all remaining questions (just press the Enter key...)

CPAN should write out a page or two of text, select the closest mirror for you and then enter interactive with command prompt waiting for commands. Please enter:

cpan[1]> install IO::Socket::PortState                  # follow defaults by pressing <Enter> if needed
cpan[3]> quit

Please observe upper/lower case in the commands above.

Now copy PortState.pm to the Perl5 library:

cp /root/.local/share/.cpan/build/IO-Socket-PortState-0.03-0/PortState.pm /usr/share/perl5/vendor_perl/IO/Socket/

This action actually breaks the YUM package system because PortState.pm will remain unmaintained in a YUM controlled directory. However, there have been no practical solution yet coming from discussions with the RHEL/CentOS maintainers for this library which is not available as a RPM.

Install pgAdmin4

pgAdmin is an administration and management tool for PostgreSQL.

The following commands will install the software:

cd /usr/src/
wget https://ftp.postgresql.org/pub/pgadmin/pgadmin4/yum/pgadmin4-redhat-repo-1-1.noarch.rpm
rpm -i pgadmin4-redhat-repo-1-1.noarch.rpm
yum install pgadmin4-desktop

For setting up the connection please use:

  • Name: projop@localhost
  • Hostname: /tmp/
    This will allow pgAdmin4 to connect via "Unix Domain Sockets" to the "projop" database without a password.
  • Port: 5432
    This doesn't matter, though.
  • Maintenance database: projop
  • Username: projop

Cleanup and Release Preparation

The following steps cleanup data after a successfull installation. These steps are not necessary for production operation.

  • Cleanup /etc/hosts and remove any installation specific entries.
  • Cleanup ]po[ log files:
cd /web/projop/log
rm *
  • Cleanup Projop "Desktop" files:
cd /web/projop/Desktop
rm -r *
  • Cleanup YUM files:
yum clean all
  • Cleanup /tmp:
cd /tmp
<delete unnecessary files>
  • Cleanup /var/tmp:
cd /var/tmp
rm -r abrt
rm -r kdecache-projop
  • Cleanup /var/spool:
cd /var/spool
du -sk *
<delete unnecessary files>
  • Cleanup /var/log:
cd /var/log
rm *
du -sk *
<delete unnecessary files>
systemctl restart rsyslog.service
  • Cleanup history files:
rm /root/.bash_history
rm /web/projop/.bash_history
rm /web/projop/.psql_history
  • Erase the disk with zeros for better compression of the VM. Please note that the first "dd" command will fail with an "No space left on device" error. Please make sure the PostgreSQL database is not active:
dd bs=1M count=1000000 if=/dev/zero of=/zero
rm /zero
  • Run SysConfig -> "Disable everything except SysConfig" in order to prepare the machine for delivery.

Upgrade ]project-open[

Please see available updates. Please read the forum and other sources in order to see if it is necessary to upgrade. Please see the V5.0 release notes for information on known issues.

Integration With Other Systems

Please see http://www.project-open.com/en/list-integration-links  for a list of supported integration links with other software packages.

Installer Preparation and Upload

The following steps are for preparing the virtual machine installer. We'll create a ZIP of the virtual machine (for both Linux and Windows users) and upload the release to SourceForge FRS:

Inside the virtual machine please run:

# yum clean all
# rm /var/tmp/*
# rm /web/projop/filestorage/backup/*
# rm /tmp/*
# rm /var/backup/*
# rm /web/projop/logs/*
# rm /web/projop/filestorage/backup/*
# xfs_sfr (defrag xfs file system)
# dd if=/dev/zero of=wipefile bs=1M; sync; rm wipefile
# vmware-toolbox-cmd disk shrinkonly

Please check that the keyboard is switched to English.

On the host machine please run:
