Docker 部署mysql 5.7.20

1 下载镜像

[root@node-11 ~]# docker pull mysql:5.7.20

2 创建mysql目录

[root@node-11 ~]# mkdir /opt/mysql/{data,conf,logs} -p
目录说明：
    data：数据目录
    conf：配置文件
    logs：日志目录

3 编辑配置文件

[root@node-11 ~]# vim /opt/mysql/conf/mysqld.cnf
[mysqld]
pid-file	= /var/run/mysqld/mysqld.pid
socket		= /var/run/mysqld/mysqld.sock
datadir		= /var/lib/mysql
lower_case_table_names = 1  ## 忽略mysql查询大小写

注意：这只是简单的mysql参数，具体的参数需要根据业务需求，自行添加即可，这里需要注意的是，涉及到mysql数据目录的话，一定要写容器内的路径，而不是映射到宿主机的目录。

4 启动

[root@node-11 ~]# docker run -d -p 3306:3306 --name mysql 
 -v /opt/mysql/data:/var/lib/mysql 
 -v /opt/mysql/logs:/var/log/mysql 
 -v /opt/mysql/conf:/etc/mysql/mysql.conf.d 
 -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7.20

参数解释：

1. --name: 容器名称
2. -p 3306: 映射端口
3. MYSQL_ROOT_PASSWORD：mysql初始密码
4. -v冒号前面是宿主机目录，后面是容器目录

查看启动状态

5 设置远程登录

[root@node-11 ~]# docker exec -it mysql /bin/bash
root@cd0fb7617eb9:/# mysql -uroot -p
