CentOS 6.1 MySQL 5.21 字符編碼設(shè)置 (gbk)

解決辦法： cp /usr/share/mysql/my-medium.cnf /etc/my.cnf ;

編輯：增加兩個(gè)編碼變量

[client]

default-character-set=gbk-
 

[mysqld]
character_set_server=gbk
datadir=/var/lib/mysql

socket = /var/lib/mysql/mysql.sock

上面設(shè)置好后，重啟mysql即可。

由于在開(kāi)發(fā)中C++ ,java，asp.net, jsp等程序中使用gbk作為數(shù)據(jù)庫(kù)操作編碼的話,并且創(chuàng)建表時(shí)也是用了gbk編碼，由于mysql使用的是utf-8的編碼，這樣在程序語(yǔ)言里查詢數(shù)據(jù)庫(kù)時(shí)，會(huì)導(dǎo)致數(shù)據(jù)獲取不到的問(wèn)題。

login mysql

>show variables like 'character%';

The server quit without updating PID file 問(wèn)題是由于當(dāng)前版本的mysql中

[mysqld]中default-character-set變量不識(shí)別，正確答案是:設(shè)置character_set_server=gbk

通過(guò)baidu，查詢的答案大都是在【mysqld】組中設(shè)置default-character-set=gbk
，所以導(dǎo)致重啟mysql時(shí) 報(bào) “The server quit without updating PID file”錯(cuò)誤。查詢?nèi)罩荆?var/lib/mysql/"主機(jī)名".err文件得知，default-character-set變量在[mysqld]中未定義。

摘要: 首先告訴你一條超級(jí)有用的定理，Linux 系統(tǒng)出錯(cuò)的時(shí)候一定要先查看錯(cuò)誤日志： #cat /var/lib/mysql/'主機(jī)名'.err

mysqld_safe mysqld from pid file /var/lib/mysql/...- ...首先告訴你一條超級(jí)有用的定理，Linux 系統(tǒng)出錯(cuò)的時(shí)候一定要先查看錯(cuò)誤日志：

#cat /var/lib/mysql/'主機(jī)名'.err

艸：是字符集和字符沖突了，所以編譯的時(shí)候要把字符和字符集選項(xiàng)都加上，并且要兼容！修改編譯參數(shù)：

#cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DEXTRA_CHARSETS=all -DENABLED_LOCAL_INFILE=1 -DWITH_READLINE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EMBEDDED_SERVER=1 -DWITH_SSL=system

艸，還是有錯(cuò)，再抓日志看看：

#cat /usr/local/mysql/data/www.pc-pub.com.err

這是啥意思呢?這是權(quán)限問(wèn)題�。ㄏ刃薷呐渲梦募�再初始化數(shù)據(jù)庫(kù)即可�。�

[root@www mysql-5.5.13]# /etc/init.d/mysql start
Starting MySQL.. SUCCESS!

記�。篖inux 系統(tǒng)下發(fā)現(xiàn)有錯(cuò)誤，記得一定要先查看日志，這樣才能在學(xué)習(xí)中不斷進(jìn)步！
