Data management for PHP applications with Docker Compose, Nginx and MariaDB

Data management for PHP applications through Docker Compose, Nginx and MariaDB

Introduction: In today’s software development, containerization has become a very popular technology, Docker, as one of the leaders, provides convenient and reliable containerization solutions. In this article, we will explore how to implement data management for PHP applications by using Docker Compose, Nginx, and MariaDB.

1. What is Docker Compose?
Docker Compose is a tool for defining and running multiple Docker containers. It uses YAML files to configure the application's services. By using Docker Compose, we can easily start, stop, and manage multiple containers, and we can specify parameters and configurations for each container.

2. Configure PHP applications using Docker Compose and Nginx

1. Install Docker and Docker Compose
   First, we need to install Docker and Docker Compose. Detailed installation steps can be found on the official Docker website.

2. Create Docker Compose file
   Create a file named docker-compose.yml in the root directory of the project and add the following content:

   version: '3'
   services:
     nginx:
       image: nginx:latest
       ports:
         - 80:80
       volumes:
         - ./nginx.conf:/etc/nginx/nginx.conf
         - ./www:/var/www/html
     php:
       image: php:7.4-fpm
       volumes:
         - ./www:/var/www/html
     mariadb:
       image: mariadb:latest
       restart: always
       environment:
         MYSQL_ROOT_PASSWORD: your_root_password
         MYSQL_DATABASE: your_database_name
         MYSQL_USER: your_mysql_username
         MYSQL_PASSWORD: your_mysql_password

   Copy after login

   This configuration file definition Three services are provided: Nginx, PHP and MariaDB. The Nginx service uses the nginx:latest image and maps port 80 of the host to port 80 of the container. The PHP service uses the php:7.4-fpm image to map the host's www directory to the container's /var/www/html directory through a shared volume. The MariaDB service uses the mariadb:latest image and sets the root password of the database, as well as the database name, username and password. Please modify these parameters according to actual needs.

3. Configuring Nginx
   Create a file named nginx.conf in the root directory of the project and add the following content:

   server {
     listen 80;
     server_name localhost;
     root /var/www/html;
     index index.php;
   
     location / {
       try_files $uri $uri/ /index.php?$query_string;
     }
   
     location ~ .php$ {
       fastcgi_pass php:9000;
       fastcgi_index index.php;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       include fastcgi_params;
     }
   }

   Copy after login

   This configuration file defines The basic configuration of Nginx redirects all requests to the index.php file to achieve parsing of PHP applications.

4. Start the Docker container
   Execute the following command to start the Docker container:

   docker-compose up -d

   Copy after login

   This command will start all services defined in the configuration file and run them in Background mode.

5. Connecting to MariaDB
   You can use any MySQL client to connect to the MariaDB database and use the username and password previously set in the configuration file.

3. Conclusion
By using Docker Compose, Nginx and MariaDB, we can easily configure and manage the data of PHP applications. This containerized solution not only provides convenient deployment and expansion, but also ensures data security and stability. I hope this article will be helpful to your study and practice.
