MySQL修改字符集編碼爲UTF8(解決中文亂碼問題)

Linux下MySQL5.6的修改字符集編碼爲UTF8（解決中文亂碼問題）

1、登陸MySQL查看用SHOW VARIABLES LIKE 'character%';下字符集，顯示以下:

+--------------------------+----------------------------+   
| 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/ |   
+--------------------------+----------------------------+   
複製代碼

2、最簡單的完美修改方法，修改mysql的my.cnf文件中的字符集鍵值（注意配置的字段細節）：
一、在[client]字段里加入default-character-set=utf8，以下：

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

二、在[mysqld]字段里加入character-set-server=utf8，以下：

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

三、在[mysql]字段里加入default-character-set=utf8，以下：

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

修改完成後，service mysql restart重啓mysql服務就生效。

| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |

| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
