The golden triangle of Docker Compose, Nginx and MariaDB: the best combination of tools for deploying PHP applications

Introduction:

In today’s Internet applications During development, deploying applications quickly and reliably is a crucial step. Docker Compose, Nginx, and MariaDB are widely recognized as the best combination of tools for deploying PHP applications. They provide easy-to-use tools and features that make application deployment simple and efficient. In this article, we will introduce the usage of Docker Compose, Nginx and MariaDB, and provide specific code examples to help readers better understand and use this powerful tool combination.

1. Introduction and usage of Docker Compose

Docker Compose is a tool used to define and run multiple Docker containers. It uses a single YAML file to define a container's configuration and dependencies, and can start, stop, and manage an entire application's container group with a single command. The following is a simple Docker Compose file example:

version: '3.8'
services:
  web:
    build: .
    ports:
      - 80:80
  database:
    image: mariadb
    environment:
      - MYSQL_ROOT_PASSWORD=secret

In the above example, we defined two services: web and database. The web service uses the Dockerfile in the current directory to build the image and maps port 80 of the container to port 80 of the host. The database service uses the official image of MariaDB and sets an environment variable to specify the MySQL root password.

To deploy an application using Docker Compose, simply go to the project directory in the terminal and run the command docker-compose up. Docker Compose will automatically build and run based on the containers defined in the configuration file.

2. Introduction and usage of Nginx

Nginx is a high-performance web server and reverse proxy server that is widely used in production environments. It can effectively handle high concurrency and load balancing, and supports flexible customization of various needs through configuration files. The following is a simple Nginx configuration file example:

server {
  listen 80;
  server_name example.com;
  
  location / {
    proxy_pass http://web:80;
    proxy_set_header Host $host;
  }
}

In the above example, we define a server block for Nginx that listens on port 80 and forwards all requests through a proxy to a Docker service named web 80 port. In this way, Nginx can forward external access traffic to the application container to achieve efficient load balancing and reverse proxy.

To use Nginx as a proxy server, just save the above configuration file as a file with a .conf suffix and copy it to the Nginx configuration directory. Then reload the Nginx configuration to make it effective.

3. Introduction and usage of MariaDB

MariaDB is a relational database management system compatible with MySQL. It has many of MySQL's advanced features and performance advantages, and through optimization and enhancement, it makes database deployment and management more convenient. The following is a simple MariaDB configuration file example:

version: '3.8'
services:
  database:
    image: mariadb
    environment:
      - MYSQL_ROOT_PASSWORD=secret

In the above example, we use the official image of MariaDB and set an environment variable to specify the MySQL root password. This way, when we start the MariaDB container, it will automatically set the password to the value we specified.

In actual applications, we can use the command docker exec to enter the running MariaDB container and perform various database management operations. This allows us to easily backup, restore and manage our application database.

Conclusion:

The golden triangle of Docker Compose, Nginx, and MariaDB is an optimal combination of tools for deploying PHP applications quickly and reliably. By using Docker Compose, we can easily define and run multiple containers and manage their dependencies. Nginx provides efficient reverse proxy and load balancing functions, allowing our applications to handle a large number of concurrent requests. Finally, MariaDB, as a MySQL-compatible database management system, provides convenient database deployment and management tools.

By using this powerful combination of tools, we can greatly simplify and accelerate the application deployment process and improve application reliability and performance. I hope that the specific code examples provided in this article can help readers better understand and apply this golden triangle combination, so as to better deploy and manage their own PHP applications.
