docker-compose 是一个可以快速进行多容器编排的神器
安装：
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
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
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:

- ./nginx/nginx.conf:/etc/nginx/nginx.conf
- ./nginx/conf.d/default..conf:/etc/nginx/conf.d/default.conf
environment:

mysql:
hostname: mysql
image: mysql:5.6
environment:
- TZ=Asia/Shanghai
ports:
- 3306:3306
networks:

- ./mysql/data:/var/lib/mysql
environment:

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