Deploy MYSQL

docker pull mysql

挂载卷保存数据文件

mkdir -p /mysql/data
chmod -p 777 /mysql/data

MySQL使用过程中的环境变量

Num	Env Variable	Description
1	MYSQL_ROOT_PASSWORD	root用户的密码
2	MYSQL_DATABASE	创建一个数据库
3	MYSQL_USER,MYSQL_PASSWORD	创建一个用户以及用户密码
4	MYSQL_ALLOW_EMPTY_PASSWORD	允许空密码

1、创建网络

docker network create --subnet 10.0.0.0/24 --gateway 10.0.0.1 marion
docker network ls
➜  ~ docker network ls | grep marion
6244609a83bb        marion              bridge              local

2、创建MYSQL container

➜  ~ docker run -v /mysql/data:/var/lib/mysql --name mysqldb --restart=always -p 3306:3306 -e MYSQL_DATABASE='wordpress' -e MYSQL_USER='marion' -e MYSQL_PASSWORD='marion' -e MYSQL_ALLOW_EMPTY_PASSWORD='yes' -e MYSQL_ROOT_PASSWORD='marion' --network=marion --ip=10.0.0.2 -d mysql
➜  ~ docker ps -a
➜  marion docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

3、运行nginx-php

mkdir -p /var/www/html
docker run --name php7 -p 9000:9000 -p 80:80 -v /var/www/html:/usr/local/nginx/html --restart=always --network=marion --ip=10.0.0.3 -d skiychan/nginx-php7
docker ps
docker exec -it cfb9556b71b3 /bin/bash
cd /usr/local/php/etc
vim php.ini
date.timezone =Asia/Shanghai

编辑nginx配置文件/usr/local/nginx/conf/nginx.conf

测试配置文件是否有问题

[root@cfb9556b71b3 sbin]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

重新加载配置文件

[root@cfb9556b71b3 sbin]# /usr/local/nginx/sbin/nginx -s reload
[root@cfb9556b71b3 sbin]#
