mysql 字符集設置

linux下/etc/mysql/my.cnf(windows下my.ini)

[client] 添加

default-character-set=utf8 默認字符集爲utf8

[mysql] 添加

default-character-set=utf8 默認字符集爲utf8

[mysqld] 添加

character-set-server=utf8
collation-server=utf8_general_ci
init_connect='set collation_connection=utf8_general_ci'
init_connect='set names utf8' (設定連接mysql數據庫時使用utf8編碼，以讓mysql數據庫爲utf8運行;
注意該參數對於連接數據庫的用戶是超級用戶組的用戶將被忽略，這樣是爲了避免該參數導致數據庫致命錯誤，而無法使用任何一個用戶連接上修改該項配置)

修改好後，重新啓動mysql 即可，查詢一下show variables like 'character%';
