linux下mysql中文乱解决办法

1、查看原有编码

mysql> show variables like 'character%'; //执行编码显示，可以看到默认是latin1
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+

2、修改/etc/my.cnf
# vim /etc/my.cnf

[client]
port = 3306
socket = /var/lib/mysql/mysql.sock
default-character-set=utf8
[mysqld]
port = 3306
socket = /var/lib/mysql/mysql.sock
character-set-server=utf8
[mysql]
no-auto-rehash

PS:[mysql]的值可以不设置
3、查看编码是否已经修改过来

mysql> show variables like 'character%';
+--------------------------+----------------------------------------+
| Variable_name | Value |
+--------------------------+----------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/local/mysql/share/mysql/charsets/ |
+--------------------------+----------------------------------------+

4、重启Mysql服务
5、重建对应的数据库和数据表
