HomeDatabaseMysql TutorialLinux下MySQL的中文不能显示及sock链接错误问题解决

安装mysql后,默认的字符集是latin1。在linux下安装mysql不像在windows上安装那像,可以选择字符集(即使当时使用了默认的字符集,安装后也可以在安装目录下修改my.ini文件),但是在linux就不太一样了。

在shell输入mysql登陆后:

mysql>show variables like '%char%';

回车后显示:

+----------------------+---------------------
| Variable_name | Value
+-----------------------+---------------------
| character_set_client | latin1
| character_set_connection | latin1
| character_set_database | latin1
| character_set_filesystem | binary
| character_set_results | latin1
| character_set_server | latin1
| character_set_system | utf8
| character_sets_dir | /usr/share/mysql/charsets/
+---------------------+----------------------

这就是它默认的设置。

接下来到/usr/share/mysql/目录下,将my-medium.cnf文件(使用其它实例配置文件也行)拷贝到/etc目录下:

pds:~# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
pds:~# vi /etc/my.cnf

分别在如下几项中添加字符集:

[client]
default-character-set=gb2312
[mysqld_safe]
default-character-set=gb2312
[mysqld]
default-character-set=gb2312
#default-table-type=innodb
[mysql]
default-character-set=gb2312

再重启mysql让配置生效:

pds:~# service mysql restart

Shutting down MySQL done
Starting MySQL done

再次登陆mysql后,查看变量:

mysql>show variables like '%char%';

+----------------------+---------------------
| Variable_name | Value
+-----------------------+---------------------
| character_set_client | gb2312
| character_set_connection | gb2312
| character_set_database | gb2312
| character_set_filesystem | binary
| character_set_results | gb2312
| character_set_server | gb2312
| character_set_system | utf8
| character_sets_dir | /usr/share/mysql/charsets/
+---------------------+----------------------

如此显示就完成了配置了,在表中插入一条含中文的记录,就不再出现乱码,但是原来插入的记录很可能还是乱码,,因为原来的字符集与当前字符集不一致。

最好将上面的gb2312改成utf8,因为utf8比gb2312更加通用些,某些情况下可能不能正常显示
