docker: docker-compose 编排lnmp容器

docker-compose 是一个可以快速进行多容器编排的神器
安装：

[code]pip install docker-compose

docker-compose -h 查看子命令：
常用的命令有：
docker-compose build # 构建镜像
docker-compose up    # 编排启动容器 -d 以守护模式启动
docker-compose start # 启动容器
docker-compose stop # 停止容器
docker-compose ps    # 查看容器
docker-compose rm    # 删除容器

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

[code]
编辑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:

执行docker-compose up -d 启动lnmp（注意需要在文件所在的路径下执行）
