mysql创建用户
创建用于localhost连接的用户并指定密码
mysql> create user 'pcom'@'localhost' identified by 'aaa7B2249';
Query OK, 0 rows affected (0.00 sec)
创建数据库
mysql> create database pcom default character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)
给本地用户授权, 这里不需要指定密码
mysql> grant all on pcom.* to 'pcom'@'localhost';
Query OK, 0 rows affected (0.00 sec)
给其他IP地址下的用户授权, 注意: 这里必须指定密码, 否则就可以无密码访问
mysql> grant all on pcom.* to 'pcom'@'192.168.0.0/255.255.0.0' identified by 'aaa7B2249';
Query OK, 0 rows affected (0.00 sec)
同理
mysql> grant all on pcom.* to 'pcom'@'172.20.0.0/255.255.0.0' identified by 'aaa7B2249';
Query OK, 0 rows affected (0.00 sec)
使设置生效
mysql> flush privileges;
Done!
