#!/bin/bash

# 创建目录
[ ! -f ./my.cnf ] && echo 'my.cnf not found.' && exit

[ ! -d /opt/mysql ] && sudo mkdir /opt/mysql
[ ! -d /opt/mysql/etc ] && sudo mkdir /opt/mysql/etc
[ ! -d /opt/mysql/etc/conf.d ] && sudo mkdir /opt/mysql/etc/conf.d
[ ! -d /opt/mysql/data ] && sudo mkdir /opt/mysql/data
[ ! -d /opt/mysql/log ] && sudo mkdir /opt/mysql/log

cp ./my.cnf  /opt/mysql/etc/

# 执行Docker进程启动mysql
# 最后一行，替换为mysql镜像ID(docker images 可以查看镜像明细)

docker run \
--privileged=true \
-p 3306:3306 \
-e MYSQL_ROOT_PASSWORD=root \
--restart=always \
-v /opt/mysql/etc:/etc/mysql \
-v /opt/mysql/data:/var/lib/mysql \
-v /opt/mysql/log:/log \
-v /usr/share/zoneinfo:/usr/share/zoneinfo \
--name mysql \
-d \
