create user laobian@'10.10.65.%' identified by "1234";

允许10.10.65.250~10.10.65.255以laobian2登录mysql:
create laobian2@'10.10.65.25%' identified by "1234";
允许10.10.65.20~10.10.65.29以laobian3登录mysql:
create laobian3@'10.10.65.2_' identified by "1234";

grant insert on laobian2.person2 to 'laobian2'@'10.10.65.%';
grant select on laobian.person to laobian@localhost；
给laobian数据库的peron表的查询授权给以localhost登录的laobian用户

grant select(id,name) on bian.person to laobian@localhost;
将bian数据库的person表的select查询权限授权给以localhost登录的laobian用户
