Linux下MySQL 5.5的修改字元集編碼為UTF8

標籤：character   linux   mysql   share   

一、登入MySQL查看用SHOW VARIABLES LIKE ‘character%’;下字元集，顯示如下：

+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+

character_set_database和character_set_server的預設字元集還是latin1。

二、最簡單的完美修改方法，修改mysql的my.cnf檔案中的字元集索引值（注意配置的欄位細節）：

1、在[client]欄位裡加入default-character-set=utf8，如下：

[client]
port = 3306
socket = /var/lib/mysql/mysql.sock
default-character-set=utf8

2、在[mysqld]欄位裡加入character-set-server=utf8，如下：

[mysqld]
port = 3306
socket = /var/lib/mysql/mysql.sock
character-set-server=utf8

3、在[mysql]欄位裡加入default-character-set=utf8，如下：

[mysql]
no-auto-rehash
default-character-set=utf8

修改完成後，service mysql restart重啟mysql服務就生效。注意：[mysqld]欄位與[mysql]欄位是有區別的。這點在網上沒人反饋過。

使用SHOW VARIABLES LIKE ‘character%’;查看，探索資料庫編碼全已改成utf8。

+--------------------------+----------------------------+
| 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/share/mysql/charsets/ |
+--------------------------+----------------------------+
