How to install php project with docker?

Use Docker to quickly build a PHP development environment

Recently a colleague came to me and hoped that I would add something to a PHP website I wrote a long time ago. Function, the local development environment built using xampp was developed at that time, but now my laptop has been updated and there is no development environment at that time. In line with the principle of not installing useless software on the computer, I thought about whether I could use Docker to build a local development environment. Therefore, this article introduces how to quickly build a local PHP development environment based on Docker for reference by students in need. use.

This article is based on 5.6-fpm-alpine3.8 and ngingx to build a PHP development environment under Mac.

Preliminary preparation

First download the required image file

$ docker pull php:5.6-fpm-alpine3.8
$ docker pull nginx
$ docker pull mysql

Users need to go to hub.docker.com, search for PHP and find themselves through tags The version I want to install is because my project has been developed for a long time and cannot support the latest PHP, so I installed version 5.6.

We need to prepare a working directory, such as lnmp, and prepare the website root directory, Nginx configuration file directory, and Nginx log directory in the working directory.

$ mkdir lnmp
$ cd lnmp
$ mkdir -p nginx/www nginx/logs nginx/conf

Create a new index.php file in the newly created www directory to check whether the PHP environment is successfully established.

<?php
  phpinfo();
?>

Prepare the nginx configuration file php.conf in the nginx/conf directory.

server {
	listen	80;
	server_name	localhost;

	location / {
		root	/usr/share/nginx/html;
		index	index.html index.htm index.php;
	}

	error_page	500 502 503 504	/50x.html;
	location = /50x.html {
		root	/usr/share/nginx/html;
	}

	location ~ \.php$ {
		fastcgi_pass	php:9000;
		fastcgi_index	index.php;
		fastcgi_param	SCRIPT_FILENAME	/www/$fastcgi_script_name;
		include		fastcgi_params;
	}
}

Arrangement file

Create docker-compose.ymlarrangement file in the working directory.

For a detailed introduction to docker-compose, please refer to my previous article Docker-compose usage introduction.

version: "2.1"
services:
    nginx:
        image: nginx
        ports:
            - "80:80"
        volumes: 
            - ~/Projects/sh-valley/docker-conf/lnmp/nginx/www:/usr/share/nginx/html
            - ~/Projects/sh-valley/docker-conf/lnmp/nginx/conf:/etc/nginx/conf.d
            - ~/Projects/sh-valley/docker-conf/lnmp/nginx/logs:/var/log/nginx
        networks:
            - lnmp-network
    php:
        image: php:5.6-fpm-alpine3.8
        volumes:
            - ~/Projects/sh-valley/docker-conf/lnmp/nginx/www:/www
        networks:
            - lnmp-network
    mysql:
        image: mysql
        ports:
            - "3306:3306"
        environment:
            - MYSQL_ROOT_PASSWORD=123456
        networks:
            - lnmp-network
networks: 
    lnmp-network:

At this point, we have completed all the preparation work and can start to check the effect immediately.

Running effect

$ docker-compose up -d
Creating network "lnmp_php-network" with the default driver
Creating lnmp_nginx_1 ... done
Creating lnmp_php_1   ... done

You will see the familiar phpinfo interface immediately.

Installing extensions

DefaultphpThe extensions provided in the image are relatively few, lacking such as mysql, gd2 and other commonly used extensions, so we need to install and enable the extension ourselves.

First enter the php container and use the php -m command to check what extensions are available locally.

You can use the docker-php-ext-install command to install the extension.

$ docker-php-ext-install mysql

After the extension is installed, it can be enabled in php.ini. We can see from phpinfo that the default php.ini is not enabled in the container environment. You can /usr/local/etc/php ##php.ini-development is copied to php.ini. Enable the extensions you need by modifying the configuration in php.ini. Below are several extension installation commands for your reference.

• docker-php-ext-source Create a /usr/src/php directory in the container
• docker -php-ext-enableEnable PHP extensions, saving us the process of manually editing php.ini
• docker-php-ext-installinstall and Enable PHP extension
##docker-php-ext-configure
• is often paired with docker-php-ext-install and is used when you need to customize the configuration of the extension
