mysql常用命令

1. 启动mysql服务: net start mysql

或者
sh $MYSQL_HOME/support-files/mysql.server start
2. 关闭mysql服务: net stop mysql
3. 以root用户登录: mysql -h localhost -u root -p 换行输入密码;
mysql -u devuser -p

采用create schema和create database创建数据库的效果一样;

6. 授权: GRANT privileges ON databasename.tablename TO username@host identified by 'password';
其中: @"%" 表示对所有非本地主机授权，不包括localhost;

grant all privileges on *.* to 'devuser'@'%' identified by '123456';
grant all privileges on *.* to 'root'@'%' identified by '123456';
7. flush privileges;--立即启用修改
8. revoke all on *.* from tester;--取消用户所有数据库（表）的所有权限
9. 删除用户: delete from mysql.user where user='devuser';
