linux下設定mysql資料庫字元集utf8

標籤：

mysql中文亂碼解決方案：將mysql資料庫編碼統一utf8

查看資料庫編碼：

show variables like ‘character%‘;

 

編輯/etc/my.cnf

[mysql]default-character-set=utf8[mysqld]datadir=/var/lib/mysqlsocket=/var/lib/mysql/mysql.sockuser=mysql# Disabling symbolic-links is recommended to prevent assorted security riskssymbolic-links=0default-character-set = utf8character_set_server = utf8#lower_case_table_names=1  忽略大小寫[mysqld_safe]log-error=/var/log/mysqld.logpid-file=/var/run/mysqld/mysqld.piddefault-character-set = utf8[mysql.server]default-character-set = utf8[client]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。　　

如果上面的都修改了還亂碼，那剩下問題就一定在connection串連層上。解決方案是在發送查詢前執行一下下面這句（直接寫在SQL檔案的最前面）：
SET NAMES ‘utf8‘;

它相當於下面的三句指令：

SET character_set_client = utf8;
SET character_set_results = utf8;
SET character_set_connection = utf8;

執行show variables like ‘character%‘ 跟下面一樣說明修改成功
