mysql权限管理
权限管理(root)
1、创建账号
# 本地账号
create user'egon1'@'localhost' identified by '123'; # mysql -uegon1 -p123
# 远程账号,客户端ip(192.168.31.10)
create user'egon1'@'192.168.31.10' identified by '123'; # mysql -uegon1 -p123 -h 服务端ip
create user'egon1'@'192.168.31.%' identified by '123'; # mysql -uegon1 -p123 -h 服务端ip
create user'egon1'@'%' identified by '123'; # mysql -uegon1 -p123 -h 服务端ip
3、授权
user: *.* ## 所有表所有权限
db: db1.* ## db1库下所有权限
tables_priv: db1.t1 ## 表t1
columns_priv: id,name ## 表中字段
放权
grant all on *.* to 'egon1'@'localhost';
grant select on *.* to 'egon1'@'localhost';
回收权限
revoke select on *.* from 'egon1'@'localhost';
select * from mysql.user\G ## cmd命令查看
对库
grant select on db1.* to 'egon1'@'localhost';
revoke select on db1.* from 'egon1'@'localhost';
对表
grant select on db1.t1 to 'egon1'@'localhost';
revoke select on db1.t1 from 'egon1'@'localhost';
对字段
grant select(id,name),update(age) on db1.t1 to 'egon1'@'localhost';
revoke select(id,name),update(age) on db1.t1 from 'egon1'@'localhost';
