CentOS6.7 64位环境下安装部署MySQL(2)


mysql> use mysql;
Database changed
mysql> UPDATE user SET password=PASSWORD('123456') WHERE user='root';
ERROR 1054 (42S22): Unknown column 'password' in 'field list'
mysql> update user set authentication_string = PASSWORD('123456') where user = 'root';

到此, 设置完mysql用户root的密码且确保mysql编码集是utf8, 注意上面, 新版本的mysql.user表里的密码字段是authentication_string


MySQL远程授权
格式如下:
mysql> grant all [privileges] on db_name.table_name to 'username'@'host' identified by 'password';
示例如下:


mysql> grant all privileges on *.* to 'root'@'%' identified by '123456';
Query OK, 0 rows affected, 1 warning (0.04 sec)


mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
mysql>
或用
mysql> grant all on *.* to 'root'@'%' identified by '123456';

到此, 完成了mysql的安装 及配置!!!
