SuiteCRM is a free, open-source customer relationship management software. In this guide, we will walk through the steps to install SuiteCRM with Nginx and secure it with a free Let's Encrypt SSL certificate on Ubuntu 22.04.

Step 1: Update Your System

Ensure your system is up-to-date by running the following commands:

sudo apt update && sudo apt upgrade

Step 2: Install Nginx Web Server

Nginx is a fast, lightweight web server. Install it using the following command:

sudo apt install nginx

Start and enable Nginx to run on boot:

sudo systemctl start nginx

sudo systemctl enable nginx

Step 3: Install PHP and Required Extensions

SuiteCRM requires PHP to run. Install PHP along with necessary extensions:

sudo apt install php-fpm php-mysql php-xml php-mbstring php-zip php-curl php-gd php-imap

Step 4: Install MySQL Server

Install MySQL as the database server for SuiteCRM:

sudo apt install mysql-server

After installation, secure MySQL:

sudo mysql_secure_installation

Create a database for SuiteCRM:

    sudo mysql -u root -p
    CREATE DATABASE suitecrm;
    CREATE USER 'suitecrmuser'@'localhost' IDENTIFIED BY 'your_password';
    GRANT ALL PRIVILEGES ON suitecrm.* TO 'suitecrmuser'@'localhost';
    FLUSH PRIVILEGES;
    EXIT;
    

Step 5: Download and Install SuiteCRM

Download SuiteCRM from the official website:

wget https://suitecrm.com/files/162/SuiteCRM-7.11/567/SuiteCRM-7.11.22.zip

Unzip the downloaded file and move it to the Nginx web root directory:

    sudo apt install unzip
    unzip SuiteCRM-7.11.22.zip
    sudo mv SuiteCRM-7.11.22 /var/www/html/suitecrm
    sudo chown -R www-data:www-data /var/www/html/suitecrm
    

Step 6: Configure Nginx for SuiteCRM

Create a new configuration file for SuiteCRM:

sudo nano /etc/nginx/sites-available/suitecrm

Add the following configuration:

    server {
        listen 80;
        server_name your_domain.com;
        root /var/www/html/suitecrm;

        index index.php index.html index.htm;
        client_max_body_size 100M;

        location / {
            try_files $uri $uri/ /index.php?$query_string;
        }

        location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
        }

        location ~ /\.ht {
            deny all;
        }
    }
    

Enable the SuiteCRM site and restart Nginx:

sudo ln -s /etc/nginx/sites-available/suitecrm /etc/nginx/sites-enabled/

sudo systemctl restart nginx

Step 7: Secure SuiteCRM with Let's Encrypt SSL
