How to Install SuiteCRM on Debian 12

SuiteCRM is a free and open-source Customer Relationship Management (CRM) platform that is designed to help businesses to manage their customer relationships, sales, marketing, and customer support activities.

It is a popular choice for organizations looking for a cost-effective CRM solution with extensive customization options.

In this tutorial, we will show you how to install SuiteCRM on Debian 12.

Step 1: Update Operating System

The first step is to ensure that your system is up-to-date. You can do this by running the following command:

# apt update && apt upgrade

Step 2: Install Apache Web Server

To install Apache, run the following command:

# apt install apache2

You can start the Apache service and configure it to run on startup by entering the following commands:

# systemctl start apache2
# systemctl enable apache2

Verify the status of the Apache service using systemctl status command:

# systemctl status apache2


● apache2.service - The Apache HTTP Server
     Loaded: loaded (/lib/systemd/system/apache2.service; enabled; preset: enabled)
     Active: active (running)
    Process: 2024 ExecStart=/usr/sbin/apachectl start (code=exited, status=0/SUCCESS)
   Main PID: 2028 (apache2)
      Tasks: 7 (limit: 2273)
     Memory: 19.2M
        CPU: 180ms
     CGroup: /system.slice/apache2.service
             ├─2028 /usr/sbin/apache2 -k start
             ├─2029 /usr/sbin/apache2 -k start
             ├─2030 /usr/sbin/apache2 -k start

Step 3: Install PHP and PHP extensions for SuiteCRM

By default, Debian12 comes with PHP version 8.2. To install PHP and the necessary extensions, run the following command:

# apt install php php-cli libapache2-mod-php php-json php-common php-mysql php-zip php-gd php-imap php-mbstring php-curl php-xml php-ldap php-pear

Once the installation is complete verify if PHP is installed:

php -v
PHP 8.2.7 (cli) (built: Jun  9 2023 19:37:27) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.2.7, Copyright (c) Zend Technologies
    with Zend OPcache v8.2.7, Copyright (c), by Zend Technologies

Then edit the php.ini file:

# nano /etc/php/8.2/apache2/php.ini

Change the following settings:

memory_limit = 256M
post_max_size = 32M
upload_max_filesize = 32M

Restart the Apache service to apply the changes:

# systemctl restart apache2

Step 4: Install MariaDB and create a database

You can install the MariaDB server with the following command:

# apt install mariadb-server mariadb-client

Start the database server daemon, and also enable it to start automatically at the next boot with the following commands:

# systemctl start mariadb
# systemctl enable mariadb

Verify the status of the MariaDB service using systemctl status command:

# systemctl status mariadb


● mariadb.service - MariaDB 10.11.3 database server
     Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; preset: enabled)
     Active: active (running)
       Docs: man:mariadbd(8)
   Main PID: 774 (mariadbd)
     Status: "Taking your SQL requests now..."
      Tasks: 9 (limit: 2273)
     Memory: 245.4M
        CPU: 5.791s
     CGroup: /system.slice/mariadb.service
             └─774 /usr/sbin/mariadbd

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script.

# mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] Y
- 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

Now run the command below to log in to the MariaDB shell.

# mysql -u root -p

Once you are logged in to your database server you need to create a database for the SuiteCRM installation:

MariaDB [(none)]> CREATE DATABASE suitecrm;
MariaDB [(none)]> CREATE USER 'suitecrm'@'localhost' IDENTIFIED BY 'Str0ng-Passw0rd';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON suitecrm.* TO 'suitecrm'@'localhost';
MariaDB [(none)]> EXIT;

Step 5: Download SuiteCRM

Download the latest stable version of SuiteCRM from the SuiteCRM website using the following command:

# wget

Unzip the downloaded release file with the following command:

# unzip

Rename it to make it simpler:

# mv /var/www/SuiteCRM-7.14.0/ /var/www/suitecrm

Enable permission for the Apache webserver user to access the files:

# chown -R www-data:www-data /var/www/suitecrm/

Step 6: Create Virtualhost for SuiteCRM

Then, create an virtual host configuration file to host SuiteCRM:

# nano /etc/apache2/sites-available/suitecrm.conf

Paste the content as shown below:

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot /var/www/suitecrm

    <Directory /var/www/suitecrm/>
	Options Indexes FollowSymLinks
	AllowOverride All
	Require all granted

    ErrorLog /var/log/apache2/
    CustomLog /var/log/apache2/ common

Remember to replace with the domain name of your server.

Save and exit the configuration file.

Then enable the "rewrite" module in Apache:

# /usr/sbin/a2enmod rewrite

To enable this site run the command:

To enable this site run the command:

# /usr/sbin/a2ensite suitecrm.conf

To implement the changes, restart Apache webserver:

# systemctl restart apache2
