docker: docker-compose 編排lnmp容器

docker-compose 是一個可以快速進行多容器編排的神器
安裝：

pip install docker-compose

    docker-compose -h 查看子命令：
    常用的命令有：
      docker-compose build # 構建鏡像
        docker-compose up    # 編排啓動容器 -d 以守護模式啓動
        docker-compose start # 啓動容器
        docker-compose stop # 停止容器
        docker-compose ps    # 查看容器
        docker-compose rm    # 刪除容器

    docker-compose構建lnmp架構示例：
    [root@CentOS7 docker]# tree ./
 ./
└── lnmp
    ├── docker-compose.yml
    ├── mysql
    │   ├── conf
    │   │   └── my.cnf
    │   ├── data
    │   
    ├── nginx
    │   ├── conf.d
    │   │   └── default.conf
    │    |
    │   └── nginx.conf
    └── web
        └── index.php

編輯docker-compose文件：
vim docker-compose.yml              
version: "2"
services:
  php:
    image: php:7.2.3-fpm
    networks:
      - lnmp
    volumes:
       -  ./web:/web
    environment: 
      - TZ=Asia/Shanghai
  nginx:
    image: nginx:1.13
    networks:
      - lnmp
    ports:
      - 80:80
    volumes:
      - ./web:/web
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./nginx/conf.d/default..conf:/etc/nginx/conf.d/default.conf
    environment: 
      - TZ=Asia/Shanghai
    links:
      - php
  mysql:
    hostname: mysql
    image: mysql:5.6
    environment:
      - TZ=Asia/Shanghai
    ports:
      - 3306:3306
    networks:
      - lnmp
    volumes:
      - ./mysql/conf:/etc/mysql/conf.d
      - ./mysql/data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: 123456
networks:
  lnmp:

執行docker-compose up -d 啓動lnmp（注意需要在文件所在的路徑下執行）
