docker 创建运行MySQL容器

创建容器并运行：

docker run -p 3306:3306 --name mysql \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=123456  \
-d mysql:5.7

# -p 3306:3306：将容器的3306端口映射到主机的3306端口
# -v /mydata/mysql/conf:/etc/mysql：将配置文件夹挂在到主机
# -v /mydata/mysql/log:/var/log/mysql：将日志文件夹挂载到主机
# -v /mydata/mysql/data:/var/lib/mysql/：将数据文件夹挂载到主机
# -e MYSQL_ROOT_PASSWORD=123456：初始化root用户的密码为123456

进入容器bash：

[root@localhost opt]# docker exec -it 81asdfrvf bash  # 81asdfrvf为容器编号

bash-4.2# mysql -hlocalhost -uroot -p
