一.Ubuntu下启动mysql方法:/etc/init.d/sudo mysqld二.用户添加bingt;mysql -u rootmysqlgt; grant 权限1,权限2,...权限n on

一.Ubuntu下启动mysql方法:
/etc/init.d/sudo mysqld

二.用户添加
bin>mysql -u root
mysql> grant 权限1,权限2,...权限n on 数据库名称.表名称 to 用户名@用户地址 identified by '连接口令';

权限1,权限2,...权限n代表select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file等14个权限。
当权限1,权限2,...权限n被all privileges或者all代替,表示赋予用户全部权限。
当数据库名称.表名称被*.*代替,,表示赋予用户操作服务器上所有数据库所有表的权限。
用户地址可以是localhost,也可以是ip地址、机器名字、域名。也可以用'%'表示从任何地址连接。
'连接口令'不能为空,否则创建失败。

例如:
mysql>grant select,insert,update,delete,create,drop on vtdc.employee to joe@10.163.225.87 identified by '123';
给来自10.163.225.87的用户joe分配可对数据库vtdc的employee表进行select,insert,update,delete,create,drop等操作的权限,并设定口令为123。

mysql>grant all privileges on vtdc.* to joe@10.163.225.87 identified by '123';
给来自10.163.225.87的用户joe分配可对数据库vtdc所有表进行所有操作的权限,并设定口令为123。

mysql>grant all privileges on *.* to joe@10.163.225.87 identified by '123';
给来自10.163.225.87的用户joe分配可对所有数据库的所有表进行所有操作的权限,并设定口令为123。

mysql>grant all privileges on *.* to joe@localhost identified by '123';
给本机用户joe分配可对所有数据库的所有表进行所有操作的权限,并设定口令为123。
