MySQL数据库操作起来命令较多，默认无法使用tab键进行补全，所以可以安装一些实用的工具进行日常的操作
mysql -u root -p --auto-rehash
vi /etc/my.cnf
[mysql]
auto-rehash
#如果之前移动过本地.repo文件需要先将本地的.repo释放出来
mysqladmin -u root -p password "密码" #安装好mysql需要设置登录密码
mysql -u root -p
grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘密码‘; #登录数据授权root可以再所有终端登录并有所有的权限，不然后面无法使用该工具
#安装环境依赖包
