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!
