Docker-compose 安装 Nginx PHP MySQL

1、创建

mkdir -p /docker/www
mkdir -p /docker/nginx/conf.d/

2、配置

vim nginx/conf.d/default.conf

server {
  listen       80;
  server_name  localhost;

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

  location ~ \.php(.*)$ {
    root          /var/www/html;
    fastcgi_pass  php:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
  }

}

 3、创建 index.html，info.php，conn.php 三个文件

# html 静态文件
vim www/index.html

<h1>welcome to nginx</h1>



# php 文件
vim www/info.php

<?php
  phpinfo();
?>


# php 连接 mysql
vim www/conn.php

<?php
        $serve = 'mysql';
        $username = 'root';
        $password = '123456';
        $dbname = 'mysql';

        $mysqli = new Mysqli($serve,$username,$password,$dbname);

        if ($mysqli->connect_error) {
                die('connect error:'.$mysqli->connect_errno);
        }

        $mysqli->set_charset('UTF-8');
        $result = $mysqli->query('select * from user');
        $data = $result->fetch_all();
        print_r($data);

?>

4、docker-compose.yml 

version: "3"

services:
  nginx:
    image: nginx
    container_name: nginx
    ports:
     - 80:80
    volumes:
     - /docker/www:/usr/share/nginx/html
     - /docker/nginx/conf.d:/etc/nginx/conf.d
  php:
    image: bitnami/php-fpm:7.1
    container_name: php-fpm
    volumes:
     - /docker/www:/var/www/html
  mysql:
    image: mysql:5.6
    container_name: mysql
    environment:
     - MYSQL_ROOT_PASSWORD=123456

5、运行

cd /docker

[root@ ~docker]# ll
total 12
-rw-r--r-- 1 root root  419 Oct 20 22:17 docker-compose.yml
drwxr-xr-x 3 root root 4096 Oct 18 16:59 nginx
drwxr-xr-x 2 root root 4096 Oct 20 22:33 www

# 启动
docker-compose up -d

# 成功后，会自动创建一个 docker-compose.yml 所在目录名 + networks 名的 bridge
# 默认为 networks 名为 defalut
[root@ ~docker]# docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
f494d9e871fc        bridge              bridge              local
2efd0aa32907        docker_default      bridge              local
0049c2e52fe2        host                host                local
d1e9a42f8a20        none                null                local

6、查看

[root@ ~docker]# docker ps
CONTAINER ID        IMAGE                 COMMAND                  STATUS               AMES
f4530f0204d7        bitnami/php-fpm:7.1   "php-fpm -F --pid ..."   9000/tcp             php-fpm
f8defe11c1eb        nginx                 "/docker-entrypoin..."   0.0.0.0:80->80/tcp   nginx
8e36b1e0280e        mysql:5.6             "docker-entrypoint..."   3306/tcp             mysql
