Setting up MariaDB Server

Now you will be setting up the mariaDb server for the vTiger installation.

Edit the MariaDB configuration /etc/mysql/mariadb.conf.d/50-server.conf using nano editor.

sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf

Under the [mysqld] section, add the following configuration.

Next, restart the mariaDB service to apply the new configuration.

sudo systemctl restart mariadb

After that, run the below command to set up the MariaDB root password.

sudo mysql_secure_installation

Now you will be asked some questions regarding the mariaDB deployment.

  • Press enter to confirm and set up the MariaDB deployment.
  • Input Y to change the authentication method to unix_socket.
  • Input Y to set up the root password for MariaDB and type the new strong password.
  • Input Y to remove the default anonymous user from the MariaDB server.
  • For the disable remote login for the root user, input Y again to confirm.
  • Now remove the default database test from the MariaDB server.
  • Lastly, input Y again to reload all tables privileges.

Setting Up PHP

In the next step, you will be configuring the PHP on your Debian server for the vTiger installation.

Edit the /etc/php/7.4/apache2/php.ini file using nano editor.

sudo nano /etc/php/7.4/apache2/php.ini

Change the default PHP configuration as follows.

memory_limit = 512M
upload_max_file_size = 100M
log_errors = Off
max_execution_time = 100

Save the file using CTRL+X and enter Y when you are done.

Now restart the Apache2 service with the below command.

Login to the MariaDB shell as user root using the below command. You will be asked for the MariaDB root password, so input the correct MAriaDB root password.

mysql -u root -p

Now run the following queries to create a new database vtigerdb with the user vtiger and password vtigerpassword.

Download vTiger CRM

The vTIger CRM provides an open-source core CRM that can be downloaded for users. And this allows you to self-hosted the vTiger CRM on your server.

Now go to the /var/www/ directory and download the vTiger source code using the wget command. At the time of this writing, the latest version of the vTiger CRM open-source version is v7.4.0.

cd /var/www/

After the download process is completed, extract the vTiger CRM source using the below command.

tar -xzvf vtigercrm7.4.0.tar.gz

Now you will see a new directory vtigercrm under the /var/www/ directory.

Change the ownership of the vtigercrm directory to the www-data user and group. This will ensure the Apache2 web server can read all source codes of the vTiger CRM.

sudo chown -R www-data:www-data vtigercrm

At this point, the DocumentRoot directory for the vTiger CRM installation is /var/www/vtigercrm. You will need to include the DocumentRoot directory for vTiger CRM on your virtual host configuration.

Setup Apache virtual host

Now it's time to create a new virtual host configuration for the vTiger CRM installation.

Before starting configuring the Apache2 virtual host, run the below command to enable some modules that are needed for the vTiger CRM.

sudo a2enmod ssl rewrite headers

You will see the following output:

enable apache2 modules

Next, create a new virtual host configuration /etc/apache2/sites-available/vtigercrm.conf using nano editor.

sudo nano /etc/apache2/sites-available/vtigercrm.conf

Input the following configuration and don't forget to change the domain name and the path of SSL certificates.

<VirtualHost *:80>
    Redirect permanent /

<VirtualHost *:443>
    ServerAdmin [email protected]
    DocumentRoot /var/www/vtigercrm

    Protocols h2 http/1.1

    SSLEngine On
    SSLCertificateFile /etc/letsencrypt/live/
    SSLCertificateKeyFile /etc/letsencrypt/live/

     <Directory /var/www/vtigercrm/>
        Options +FollowSymlinks
        AllowOverride All
        Require all granted

     ErrorLog /var/log/apache2/vtigercrm_error.log
     CustomLog /var/log/apache2/vtigercrm_access.log combined

Save the configuration by pressing the CTRL+X button and entering Y to confirm.

Now activate the vtigercrm.conf virtual host configuration using the below command. Then verify Apache2 configurations to make sure you don't have an error.

sudo a2ensite vtigercrm.conf
sudo apachectl configtest

You will see the output Syntax OK, which means Apache2 configurations are valid. If there is an error, you will see a different output message.

Lastly, restart the Apache2 service to apply new changes on the Apache2 webserver.
