linux下mysql中文亂解決辦法

1、查看原有編碼

mysql> show variables like 'character%'; //執行編碼顯示，可以看到默認是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]的值可以不設置

3、查看編碼是否已經修改過來

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、重啓Mysql服務

5、重建對應的數據庫和數據表
