SQL:数据库授权
莫忘
授权后及时刷新:flush privileges;
创建用户
设置密码:
insert into mysql.user(Host,User,Password) values("xx.xx.38.xx","rrw_reader",password("xxxxxx"));
更新密码:
update mysql.user set password=password(‘新密码’) where User="reader" and Host="";
某些时候需要放开更大权限,比如写存储过程等:
update user set Super_priv='Y' where User='xx'
update mysql.user SET Grant_priv ='Y', Super_priv='Y' WHERE User='xx';
普通数据用户通用增删改查
单独授权:
grant select on testdb.* to common_user@'%';
grant insert on testdb.* to common_user@'%';
grant update on testdb.* to common_user@'%';
grant delete on testdb.* to common_user@'%';
grant execute on testdb.* to common_user@'%';
联合授权:
grant select, insert, update, delete on testdb.* to common_user@'%'
grant all privileges on testdb.* to common_user@localhost identified by 'testdb';
flush privileges;
读授权
grant select on test_db_name.test_table_name to rrw_reader@'xxx.xxx.38.242';
flush privileges;
插入更新授权
grant insert on testdb.* to common_user@'%';
grant update on testdb.* to common_user@'%';
flush privileges;
删除授权
grant delete on testdb.* to common_user@'%';
flush privileges;
例程授权
grant create routine on bi2_cache.* to xxx@'xx.xx.38.242';
grant alter routine on bi2_cache.* to xxx@'xx.xx.38.242';
