對(duì)于mysql數(shù)據(jù)庫(kù)來(lái)講編碼是一個(gè)比較重要的參數(shù)了,特別在以前低版本的mysql中,如果編碼未設(shè)置好中文就會(huì)是亂碼了,下面我給各位整理了一篇關(guān)于mysql數(shù)據(jù)庫(kù)的字符編碼設(shè)置教程供各位參考.

默認(rèn)登錄mysql之后show variables like ‘%character%’,出現(xiàn):

1. mysql》 show variables like ‘%character%’; 
2. +--------------------------+----------------------------+ 
3. | Variable_name | Value |  --Vevb.com 
4. +--------------------------+----------------------------+ 
5. | character_set_client | latin1 | 
6. | character_set_connection | latin1 | 
7. | character_set_database | latin1 | 
8. | character_set_filesystem | binary | 
9. | character_set_results | latin1 | 
10. | character_set_server | latin1 | 
11. | character_set_system | utf8 | 
12. | character_sets_dir | /usr/share/mysql/charsets/ | 
13. +--------------------------+----------------------------+ 

1. 找到mysql的配置文件,拷貝到etc目錄下,第一步很重要,使用find命令查找cnf文件,記得不要去找my.cnf因?yàn)樗灰欢ù嬖?而應(yīng)該找*.cnf.

1. [root@linuxserver classes] find / -iname *.cnf -print 
2. /usr/share/doc/mysql-server-4.1.12/my-medium.cnf 
3. /usr/share/doc/mysql-server-4.1.12/my-huge.cnf 
4. /usr/share/doc/mysql-server-4.1.12/my-innodb-heavy-4G.cnf 
5. /usr/share/doc/mysql-server-4.1.12/my-large.cnf 
6. /usr/share/doc/mysql-server-4.1.12/my-small.cnf 
7. /usr/share/texmf/web2c/mktex.cnf 
8. /usr/share/texmf/web2c/texmf.cnf 
9. /usr/share/texmf/web2c/fmtutil.cnf 
10. /usr/share/texmf/tex/jadetex/jadefmtutil.cnf 
11. /usr/share/ssl/openssl.cnf 

找到之后,復(fù)制一個(gè)出來(lái):

cp /usr/share/doc/mysql-server-4.1.12/my-large.cnf /etc/my.cnf

2.打開(kāi)my.cnf修改編碼:

vi /etc/my.cnf

在[client]下增加default-character-set=utf8,在[mysqld]下增加default-character-set=utf8,同時(shí)加上init_connect=‘SET NAMES utf8’(設(shè)定連接mysql數(shù)據(jù)庫(kù)時(shí)使用utf8編碼,以讓mysql數(shù)據(jù)庫(kù)為utf8運(yùn)行)

重新啟動(dòng)mysql，執(zhí)行：sudo /etc/init.d/mysql stop 然后sudo /etc/init.d/mysql start.

1. mysql》 show variables like ‘%character%’; 
2. +--------------------------+----------------------------+ 
3. | Variable_name | Value | 
4. +--------------------------+----------------------------+ 
5. | character_set_client | utf8 |  --Vevb.com 
6. | character_set_connection | utf8 | 
7. | character_set_database | utf8 | 
8. | character_set_filesystem | binary | 
9. | character_set_results | utf8 | 
10. | character_set_server | utf8 | 
11. | character_set_system | utf8 | 
12. | character_sets_dir | /usr/share/mysql/charsets/ | 
13. +--------------------------+----------------------------+ 

即使做了以上修改如果直接數(shù)據(jù)庫(kù)再創(chuàng)建表,然后存入中文,取出來(lái)的會(huì)是問(wèn)號(hào),解決的辦法是.

創(chuàng)建數(shù)據(jù)庫(kù)的時(shí)候指明默認(rèn)字符集為utf8,如:

create database test default character set utf8;
