Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

docker pull mysql:5.7Copy

docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 --name cyt_mysql mysql:5.7Copy

-p:端口映射，映射容器的3306
后面就是密码和名称Copy

docker pull php:7.2-fpmCopy

docker run -d -v /var/nginx/www/html:/var/www/html -p 9000:9000 --link cyt_mysql:mysql --name cyt_phpfpm php:7.2-fpm 
Copy

-v 前面是主机的目录映射容器的目录
link：挂上msyqlCopy

进入到PHP容器 (可以用name也可以用容器id)
docker exec cyt_phpfpm /bin/bash
就会到var/www/html 目录，新建一个PHP文件
touch test.php
然后退出容器
exit
到主机的 var/nginx/www/html 目录下也出现了个test.phpCopy

docker-php-ext-install pdo_mysql（curl ...）

要安装php-redis的话，需要另外下载,执行下面这个命令就可以了，有问就no或者空格就好
pecl install redis && docker-php-ext-enable redis

安装后 php-m
发现就都有了哦

docker pull ngixn:1.12.2Copy

docker run -d -p 80:80 --name cyt_nginx -v /var/nginx/www/html:/var/www/html --link cyt_phpfpm:phpfpm --name cyt_nginx nginx:1.12.2Copy

-p:映射80端口
-v:映射目录，最好和PHP的一样
-name:容器名
-link：跟PHP关联Copy

docker exec -it cyt_nginx /bin/bash
Copy

前面有#号去掉
