设置密码(不需要重启数据库即可生效)。

mysql> set password for ‘root‘@‘localhost‘ =password(‘123456‘);
Query OK, 0 rows affected (0.00 sec)

mysql> 

配置

mysql配置文件为/etc/my.cnf

1、编码

mysql配置文件为/etc/my.cnf

最后加上编码配置

[mysql]
default-character-set =utf8

这里的字符编码必须和/usr/share/mysql/charsets/Index.xml中一致。

2、远程连接设置

把在所有数据库的所有表的所有权限赋值给位于所有IP地址的root用户。

mysql> grant all privileges on *.* to root@‘%‘identified by ‘123456‘;

如果是新用户而不是root，则要先新建用户

mysql>create user ‘username‘@‘%‘ identified by ‘password‘;  

此时就可以进行远程连接了。
