How to Install SuiteCRM on Debian 10 Buster

SuiteCRM is a free and open source alternative to the popular customer relationship management system SugarCRM. It became popular when SugarCRM decided to stop development of its community edition, on which SuiteCRM is based. This guide will explain the installation of SuiteCRM on a Debian 10 system.


  • A fresh Debian 10 system.
  • Root SSH or console access.
  • A domain name pointing to the server’s IP address.

NOTE: All occurences of should be replaced with your own domain name.

Step 1: update and install required software.

apt update 
apt upgrade -y

SuiteCRM is written in PHP, and can run on Apache2, so you will need to install the Apache web server, PHP itself, PHP modules, and MariaDB.

apt install -y apache2 mariadb-server mariadb-client php php-common php-zip php-mysql php-gd php-curl php-imap php-mbstring php-xml php-json libapache2-mod-php unzip libpcre3

Step 3: MariaDB setup.

Before creating a database, tighten your MariaDB security by running the mysql_secure_installation script:


Answer all of the questions as shown below and make sure you choose a strong password for the root user:

Enter current password for root: Press <enter>
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

Once the script exits, log into the MySQL shell with the following command:

mysql -u root -p

Enter your root password you chose earlier, then the following to create a database for SuiteCRM:

MariadDB [(none)]> CREATE DATABASE suitecrm;

Create a database user with the following command:

MariaDB [(none)]> CREATE USER 'suitecrm'@'localhost' IDENTIFIED BY 'StrongPasswordHere';

Grant privileges to the database:

MariaDB [(none)]> GRANT ALL PRIVILEGES ON suitecrm.* TO 'suitecrm'@'localhost';

Exit from the MySQL shell:

MariaDB [(none)]> \q

Step 4: Download SuiteCRM.

First, copy the download link for the latest stable version of SuiteCRM from their official download page, and download it as follows (use the latest URL instead):

wget -O

Next, move the extracted directory to the web root:

mv SuiteCRM* /var/www/html/suitecrm

Next, set correct ownership and permissions:

cd /var/www/html/suitecrm
chown -R www-data:www-data .
chmod -R 755 .
chmod -R 775 cache custom modules themes data upload
chmod 775 config_override.php 2> /dev/null

Step 5: PHP configuration.

Using a text editor of your choice, open /etc/php/7.3/apache2/php.ini for editing and make changes according to the following values:

memory_limit = 256M
post_max_size = 64M
upload_max_filesize = 64M

Step 6: Configure Apache for SuiteCRM.

Create an Apache virtual host configuration file for SuiteCRM using a text editor of your choice. For example:

vim /etc/apache2/sites-available/suitecrm80.conf

Add the following lines:

<VirtualHost *:80>

 DocumentRoot /var/www/html/suitecrm

 <Directory /var/www/html/suitecrm>
    Options FollowSymLinks
    AllowOverride All

 ErrorLog /var/log/apache2/suitecrm-error.log
 CustomLog /var/log/apache2/suitecrm-access.log common


Then save and close the file. Enable the site with the following command:

a2ensite suitecrm80.conf

Finally, reload the Apache config:

systemctl reload apache2

Step 7: HTTPS configuration (optional, highly recommended)

Install certbot, which we will use to obtain a free SSL certificate:

apt install -y certbot

Temporarily stop the Apache service:

systemctl stop apache2.service

Obtain a certificate for your domain:

certbot certonly --standalone --agree-tos -m youremail@domain.tld -d

Restart Apache:

systemctl start apache2.service

To setup redirection from HTTP to HTTPS, open the file /etc/apache2/sites-available/suitecrm80.conf in a text editor and add the following lines before the closing virtual host tag (</VirtualHost>)

RewriteEngine on
RewriteCond %{SERVER_NAME}
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]

Then enable the apache rewrite and ssl modules:

a2enmod rewrite
a2enmod ssl

We’ll now create the necessary configuration for HTTPS, paste the following in /etc/apache2/sites-available/suitecrm443.conf:

<VirtualHost *:443> 

  DocumentRoot /var/www/html/suitecrm

  SSLEngine on
  SSLCertificateFile /etc/letsencrypt/live/
  SSLCertificateKeyFile /etc/letsencrypt/live/
  SSLProtocol all -SSLv2 -SSLv3
  SSLHonorCipherOrder on
  SSLCompression off
  SSLOptions +StrictRequire

  <Directory /var/www/html/suitecrm>
    Options FollowSymLinks
    AllowOverride All

  ErrorLog /var/log/apache2/suitecrm-error.log
  CustomLog /var/log/apache2/suitecrm-access.log common


Then enable it and restart the apache service:

a2ensite suitecrm443.conf
systemctl restart apache2.service

Step 8: Web Installer

Open your web browser and navigate to to finalize the installation process. Follow the steps below:

1. You will first have to read and accept the license, terms and conditions, then click “Next”.

2. SuiteCRM will check your environment, make sure all tests show “OK” then proceed to the next step.

3. Fill in the form as shown below:

  • Specify Database Type: MySQL.
  • Database Name: suitecrm.
  • Host Name: localhost.
  • User: suitecrm.
  • Password: Enter the password you chose during MySQL user creation in step 3.
  • SuiteCRM Database User: Same as Admin User.
  • SuiteCRM Application Admin Name: Username of your choice.
  • SuiteCRM Admin User Password: Strong password of your choice.
  • URL of SuiteCRM Instance: or if you configured HTTPS.
  • Email Address: A valid email address for the site administrator.

Modify the remaining settings if needed.

Step 9: Crontab

We need to setup a cron job in order to run SuiteCRM schedulers, use this command:

crontab -e -u www-data

And add the following line to the bottom:

*    *    *    *    *     cd /var/www/html/suitecrm; php -f cron.php > /dev/null 2>&1

Your SuiteCRM installation is now complete.
