授权案例总结
host 列: %,localhost,127.0.0.1,::1 1）授权普通用户,具有查询、插入、更新、删除 itpux 这个数据库所有表数据的权限。 grant select, insert, update, delete on itpux.* to itpux1@'%'; flush privileges; show grants for itpux1@'%' 2）开发人员授权：创建/删除/修改-表/索引/视图/存储过程/函数等权限 create user dev@'%' identified by 'dev'; grant create,alter,drop on itpux1.* to dev@'%'; flush privileges; show grants for dev@'%'; create user dev@'10.0.0.%' identified by 'dev'; grant create,alter,drop on itpux1.* to dev@'10.0.0.%'; flush privileges; show grant for dev@'10.0.0.%'; 3）操作mysql外键的权限 grant references on itpux1.* to dev@'%'; flush privileges; 4）操作mysql临时表的权限 grant create temporary tables on itpux1.* to dev@'%'; flush privileges; 5）操作mysql索引的权限 grant index on itpux1.* to dev@'%'; flush privileges; 6）操作mysql视图的权限 grant create view,show view on itpux1.* to dev@'%'; flush privileges; 7）操作mysql存储过程/函数的权限 grant create routine,alter routine,execute on itpux1.* to dev@'%'; 8）授权一个普通的dba用户，可以管理某一个数据库 grant all privileges on itpux to itpuxdba@'localhost' identified by 'itpuxdba'; flush privileges; 9）授权一个高级的dba用户，可以管理所有的数据库 grant all privileges on *.* to alldba@'localhost' identified by 'alldba'; flush privileges; 10）授权针对所有的数据库 grant all privileges on *.* to alldba@'localhost'; flush privileges； 11）授权针对单个的数据库 grant all privileges on itpux to alldbae'LocaLhost'i grant select on itpux.* to alldba@'localhost'; flush privileges; 12）授权针对所有的数据库 grant select on itpux.* to alldba@'locaLhost'; flush privileges; 13）授权针对单个列 grant select（deptno,dname） on itpux.dept to alldba@'localhost'; flush privileges; 14）授权针对存储过程和函数 grant execute on procedure 库名.过程名 to alldba@'localhost'; grant execute on function 库名.函数名 to alldba@'localhost'; flush privileges;
revoke 语法
1）授权针对所有的数据库 revoke revoke all privileges on *.* from alldba@'localhost'; flush privileges； 2）授权针对单个的数据库 revoke all privileges on itpux.* from alldba@'locaLhost'; revoke select on itpux.* from alldba@'localhost'; flush privileges; 3）授权针对所有的数据库 revoke select on itpux.* from alldba@'locaLhost'; flush privileges; 4）授权针对单个列 revoke select（deptno,dname） on itpux.dept from alldba@'localhost'; flush privileges; 5）授权针对存储过程和函数 revoke execute on procedure 库名.过程名 from alldba@'localhost'; revoke execute on function 库名.函数名 from alldba@'localhost'; flush privileges; show grants for alldba@'localhost' show grants for itpux1@'localhost'
另类方法：直接修改授权表回收授权-不建议使用
select user,host from mysql.user delete from mysql.user where user='alldba' and host='localhost'; commit； flush privileges; select user,host from mysql.user;
删除用户及重命名用户
select user,host from mysql.user; drop user dev; drop user dev@'%'; drop user dev@'192.168.1.%'; select user,host from mysql.user where user like 'dev%'; select user,host from mysql.user; rename user 'itpuxdba'@'localhost' to 'itpuxdba1'@'localhost';
