前言
本文介绍银河麒麟桌面操作系统V10上通过麒麟软件商店安装MySQL5.7、MySQL Workbench及其基本使用方法
一、安装MySQL5.7
点击UK图标、所有程序，找到麒麟软件商店
输入mysql
点击MySQL服务器下面的安装按钮
输入用户密码，点击授权
等待安装完成
二、安装MySQL Workbench
参考上面流程，继续安装workbench，点击MySQL工作台下面的安装按钮
输入密码，授权
等待安装完成
三、使用MySQL Workbench管理MySQL实例
启动mysql服务
输入以下指令，启动mysqld服务进程
sudo systemctl start mysql
输入以下指令，查看服务状态
sudo systemctl status mysql
检查端口监听状态
sudo netstat -lnetp | grep 3306
修改监听地址
注意mysqld监听的地址是127.0.0.1，将其修改成0.0.0.0，操作方法如下：
vim打开配置文件
sudo vim /etc/mysql/mysql.conf.d/mysql.conf
采用方向键，移动光标到箭头位置
输入指令i
进入编辑模式，将127.0.0.1改为0.0.0.0，按下Esc进入指令模式，输入指令:wq 保存退出
检查连接监听
设置root密码
mysql默认安装后，root是采用socket方式登陆，借助mysql字符界客户端授权root远程登陆
说明：auth_socket插件。该插件不关心，也不需要密码。它只检查用户是否使用UNIX套接字进行连接，然后比较用户名。注意采用sudo 切换到root权限
为了检点，直接删掉原来的root账户信息，创建一个新的
# sudo mysql[sudo] yeqiang 的密码：Welcome to the MySQL monitor.

查看服务器状态
总结
借助麒麟应用商店，可以方便安装mysql及workbench。
注意：配置root账号是，原账号做了一定限制，为了简单起见，可参考本文先删除root账号信息，再通过grant创建。否则容易出现access denied 错误。
