MySql linux 相关配置
1、字符集设置成UTF8
修改/etc/my.cnf(如果没有,将mysql下的my-medium.conf拷贝至/etc下并修改名字成,my.cnf)
在[client]和[mysqld]中添加
default-character-set = utf8
重启服务即可
2、修改MySQL密码
(1.)

        SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');      

(2.)

         mysql> use mysql;         mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';         mysql> FLUSH PRIVILEGES;       

(3.)

         mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='root';         mysql> FLUSH PRIVILEGES;           

3、修改访问权限

         mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;         mysql> FLUSH PRIVILEGES;
