Docker Installation of PHP

Installing PHP Image

Method One: docker pull php

Search for the PHP image on Docker Hub:

You can view other versions of PHP by sorting, with the default being the latest version php:latest.

Additionally, we can use the docker search php command to view available versions:

tutorialpro@tutorialpro:~/php-fpm$ docker search php

Here, we pull the official image with the tag 5.6-fpm:

tutorialpro@tutorialpro:~/php-fpm$ docker pull php:5.6-fpm

After the download is complete, we can find the image with the repository name php and tag 5.6-fpm in our local image list:

tutorialpro@tutorialpro:~/php-fpm$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

Nginx + PHP Deployment

For Nginx deployment, refer to Docker Installation of Nginx, and some Nginx configurations can be found in this article.

Start PHP:

$ docker run --name myphp-fpm -v ~/nginx/www:/www -d php:5.6-fpm

Command explanation:

--name myphp-fpm: Names the container as myphp-fpm.
-v ~/nginx/www:/www: Mounts the project directory www from the host to /www in the container.

Create the directory ~/nginx/conf/conf.d:

mkdir ~/nginx/conf/conf.d

Add the file ~/nginx/conf/conf.d/tutorialpro-test-php.conf with the following content:

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;
    }
}

Configuration file explanation:

php:9000: Indicates the URL for the php-fpm service, which we will explain further.
/www/: The storage path for PHP files in myphp-fpm, mapped to the local ~/nginx/www directory.

Start Nginx:

docker run --name tutorialpro-php-nginx -p 8083:80 -d \
    -v ~/nginx/www:/usr/share/nginx/html:ro \
    -v ~/nginx/conf/conf.d:/etc/nginx/conf.d:ro \
    --link myphp-fpm:php \
    nginx

-p 8083:80: Port mapping, mapping port 80 in nginx to port 8083 on the local machine.
~/nginx/www: The storage directory for local HTML files, /usr/share/nginx/html is the storage directory for HTML files inside the container.
~/nginx/conf/conf.d: The storage directory for local Nginx configuration files, /etc/nginx/conf.d is the storage directory for Nginx configuration files inside the container.
--link myphp-fpm:php: Incorporates the network of myphp-fpm into nginx by modifying /etc/hosts in nginx, mapping the domain php to 127.0.0.1, allowing nginx to access php-fpm via php:9000.

Next, create the file index.php in the ~/nginx/www directory with the following code:

<?php
echo phpinfo();
?>

Open http://127.0.0.1:8083/index.php in your browser, and you should see the following:
