In this guide, we will show you how to install the OTRS Community edition from the source on Ubuntu 22.04. To do this, follow the steps below.
Install Required Packages For OTRS
First, you need to update your local package index with the following command:
sudo apt update
Then, use the following command to install the required build tools on your Ubuntu system:
sudo apt install perl libapache2-mod-perl2 libdbd-mysql-perl libtimedate-perl \
libnet-dns-perl libnet-ldap-perl libio-socket-ssl-perl libpdf-api2-perl \
libdbd-mysql-perl libsoap-lite-perl libtext-csv-xs-perl libjson-xs-perl \

libjavascript-minifier-xs-perl libdbd-odbc-perl libcss-minifier-xs-perl \
libdbd-pg-perl libdatetime-perl apache2 mariadb-server mariadb-client -y
Download the latest OTRS Source Code
At this point, you need to create an OTRS system user account by using the command below:
sudo useradd -r -m -d /opt/otrs -c "OTRS User" -s /usr/sbin/nologin otrs
Then, visit the OTRS Community Edition Downloads page and get the latest package by using the wget command and extract it in the /opt/otrs directory:
# sudo wget https://otrscommunityedition.com/download/otrs-community-edition-6.0.39.tar.gz
# sudo tar xvfz otrs-community-edition-6.0.39.tar.gz -C /opt/otrs --strip-components=1
Next, run the OTRS Perl script on Ubuntu 22.04 to check if all required modules are in place:
sudo perl /opt/otrs/bin/otrs.CheckModules.pl
Output
o Apache::DBI......................ok (v1.12)
o Apache2::Reload..................ok (v0.13)
o Archive::Tar.....................ok (v2.38)
o Archive::Zip.....................ok (v1.68)
o Crypt::Eksblowfish::Bcrypt.......ok (v0.009)
o CSS::Minifier::XS................ok (v0.13)
o Date::Format.....................ok (v2.24)
o DateTime.........................ok (v1.55)
o DateTime::TimeZone.............ok (v2.51)
o DBI..............................ok (v1.643)
o DBD::mysql.......................ok (v4.050)
o DBD::ODBC........................ok (v1.61)
...
Note: If any Perl module is missing, install them using the package manager.
Activate Default OTRS Configuration
At this point, you need to activate the default OTRS configuration, /opt/otrs/Kernel/Config.pm.dist, by renaming it to remove the .dist extension. To do this, run the following command:
sudo cp /opt/otrs/Kernel/Config.pm{.dist,}
When you are done, check other required modules are ok by using the following command:
# sudo perl -cw /opt/otrs/bin/cgi-bin/index.pl
# sudo perl -cw /opt/otrs/bin/cgi-bin/customer.pl
# sudo perl -cw /opt/otrs/bin/otrs.Console.pl
# sudo perl /opt/otrs/bin/otrs.SetPermissions.pl
Create OTRS Database User on Ubuntu 22.04
At this point, you need to run the MySQL security script:
sudo mysql_secure_installation
Set a password for your MariaDB and answer the question by entering the y.
Enter current password for root (enter for none):
Set root password? [Y/n]: Y
Enter Password:
Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]: Y
Reload privilege tables now? [Y/n]: Y
Then, log in to your MariaDB shell with the following command
sudo mysql -u root -p
Now use the following command to create the OTRS database on Ubuntu 22.04:
MariaDB [(none)]> create database otrsdb character set utf8 collate utf8_general_ci;
Next, use the following command to create the database user and grant all the privileges to it:
MariaDB [(none)]> grant all on otrsdb.* to otrsuser@localhost identified by 'password';
Flush the privileges and exit from the MariaDB shell:
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit;
At this point, edit the MariaDB configuration file and tweak some settings:
sudo vi /etc/mysql/mariadb.conf.d/50-server.cnf
Update the following lines inside the [mysqld] section as shown below:
max_allowed_packet = 64M
query_cache_size = 32M
innodb_log_file_size = 256M
When you are done, save and close the file.
To apply the changes, restart the MariaDB service:
sudo systemctl restart mariadb
Configure Apache For OTRS on Ubuntu 22.04
At this point, you need to link the OTRS Apache configuration file to the Apache web root directory to serve OTRS via Apache. To do this, run the command below:
sudo ln -s /opt/otrs/scripts/apache2-httpd.include.conf /etc/apache2/sites-enabled/
Disable the default Apache site by running the command below:
sudo a2dissite 000-default.conf
Next, enable the required Apache modules with the following command:
sudo a2enmod perl version deflate filter headers
Set the correct ownership for the /opt/otrs directory:
# sudo chown -R otrs: /opt/otrs/
# sudo usermod -aG www-data otrs
Update OTRS file permissions by using the command below on Ubuntu 22.04:
sudo /opt/otrs/bin/otrs.SetPermissions.pl --web-group=www-data
Check Apache configuration for any error:
sudo apachectl -t
Output
Syntax OK
To apply the changes, restart the Apache service:
sudo systemctl restart apache2
If you have a firewall running on your server, you need to allow external access to Apache service:
sudo ufw allow 80/tcp
Access OTRS Web Interface
At this point, you can access your OTRS through the web interface by typing your server’s IP address in your web browser followed by /otrs/installer.pl:
You will see the OTRS Welcome screen on Ubuntu 22.04. Click Next to continue.

Next, Accept the license and Continue.

# sudo cp /opt/otrs/var/cron/otrs_daemon{.dist,}
