Docker's Nginx with PHP

1. Purpose

The PHP container and container Nginx communicate, began to build PHP development environment

2. Configure Nginx

拉取Nginx镜像
localhost:nginx_fpm sukangshen$ docker pull nginx
Using default tag: latest
latest: Pulling from library/nginx

3. Configure PHP

Pull PHP image

localhost:nginx_fpm sukangshen$ docker pull php:7.2-fpm

Php-fpm using mirroring application container opening php-fpm

localhost:nginx_fpm sukangshen$ docker run -d --name myFpm -p 9000:9000 -v ~/www/my_test/nginx_fpm/html:/usr/share/nginx/html php:7.2-fpm

3. Check whether a successful start

localhost:nginx_fpm sukangshen$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
9da9bbb80a88        nginx               "nginx -g 'daemon of…"   18 minutes ago      Up 18 minutes       0.0.0.0:8082->80/tcp     myNginx
e040f8926273        php:7.2-fpm         "docker-php-entrypoi…"   18 minutes ago      Up 18 minutes       0.0.0.0:9000->9000/tcp   myFpm

4. View the IP address of PHP

docker inspect 容器名  | grep "IPAddress"
localhost:nginx_fpm sukangshen$ docker inspect myFpm | grep "IPAddress"
Error: No such object: myFpm
localhost:nginx_fpm sukangshen$ docker inspect optimistic_varahamihira | grep "IPAddress"
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.2",
                    "IPAddress": "172.17.0.2",

5. Modify the configuration nginx

In the container is not vim command, so you can not modify the configuration file directly in the container. So we have to solve this problem through alternative ways, or only vim installed in each container.

First, log on to the corresponding container, check the configuration path, which will be used in the following modifications.

docker exec -it myNginx /bin/bash

##查看nginx的配置文件
/etc/nginx/conf.d/default.conf

Exit the command line, do not use the exit, because the exit vessel will stop. As used herein, ctrl + p + q to exit the container.
Copy using a dedicated configuration file copy command to the host, then (this is the alternative method) in the host editor

docker cp myNginx:/etc/nginx/conf.d/default.conf ./default.conf

Here used to query the last step of the configuration file path information

In the host portion php modify the configuration file, as follows:

location ~ \.php$ {
   fastcgi_pass   172.17.0.2:9000;
   fastcgi_index  index.php;
   fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html$fastcgi_script_name;
   fastcgi_param  SCRIPT_NAME      $fastcgi_script_name;
   include        fastcgi_params;
}

Again use the Copy command to copy it into the container and then into the container again, nginx reload configuration file

docker cp ./default.conf myNginx:/etc/myNginx:/etc/nginx/conf.d/default.conf

Nginx into the container reload the configuration file

docker exec -it myNginx /bin/bash
service nginx reload

Then a successful visit, good night
