Linux下MySQL5.6的修改字符集編碼爲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/ |

+--------------------------+----------------------------+

 

character_set_database和character_set_server的默認字符集仍是latin1。

 

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

 

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

 

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

 

[mysql]

no-auto-rehash

default-character-set=utf8

 

 

修改完成後，service mysql restart重啓mysql服務就生效。注意：[mysqld]字段與[mysql]字段是有區別的。這點在網上沒人反饋過。

 

使用SHOW VARIABLES LIKE ‘character%’;查看，發現數據庫編碼全已改爲utf8。
