差點被中文搞崩了,寫了一個程序,評論功能,結果中文根本無法識別,記錄一下中文亂碼的問題

檢視預設字符集 
#mysql -u root - p 
#(輸入密碼) 

mysql> show variables like 'character_set%';

可以看到你的編碼..我全是utf-8結果還是亂碼了.

結果還是會導致中文亂碼,

最後發現,其實是需要去修改 /etc/my.cnf的配置檔案才可以

在mysqld上面加入[client]標籤.插入character-set-server=utf8 而不是 default-character-set=utf8 

在mysqld標籤中插入character-set-server=utf8 而不是 default-character-set=utf8 
否則會報：Starting MySQL...The server quit without updating PID file [失敗]lib/mysql/localhost.localdomain.pid).異常

最後在插入[mysql]default-character-set=utf8

# For advice on how to change settings please see

[client]
character-set-server=utf8

[mysqld]
character-set-server=utf8

 重新啟動mysql伺服器

一、啟動方式
1、使用 service 啟動：service mysqld start
2、使用 mysqld 指令碼啟動：/etc/inint.d/mysqld start
3、使用 safe_mysqld 啟動：safe_mysqld&
 
二、停止
1、使用 service 啟動：service mysqld stop
2、使用 mysqld 指令碼啟動：/etc/inint.d/mysqld stop
3、 mysqladmin shutdown 
 
三、重啟
1、 使用 service 啟動：service mysqld restart

 

完成
