Nginx + PHP Deployment

Start PHP.

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

Command description.

• –name myphp-fpm : Names the container as myphp-fpm.
• -v ~/nginx/www:/www : Mount the directory www of the project in the host to /www of the container

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

mkdir ~/nginx/conf/conf.d 

Add the ~/nginx/conf/conf.d/apidemos-test-php.conf file to that directory, with the following contents.

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 description.

• php:9000: represents the URL of the php-fpm service, which we will specify below.
• /www/: is the path to store php files in myphp-fpm, mapped to the local ~/nginx/www directory.

To start nginx.

docker run --name apidemos-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 80 in nginx to local port 8083.
• ~/nginx/www: is the local html file storage directory, /usr/share/nginx/html is the container html file storage directory.
• ~/nginx/conf/conf.d: is the directory where local nginx configuration files are stored, and /etc/nginx/conf.d is the directory where nginx configuration files are stored inside the container.
• –link myphp-fpm:php: Merges the network of myphp-fpm into nginx\ and maps the domain php to 127.0.0.1 by modifying /etc/hosts in nginx, allowing nginx to access php-fpm via php:9000. fpm.

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

<?php
echo phpinfo();
?>

The browser opens http://127.0.0.1:8083/index.php and displays the following.
