linux下设置mysql编码

?

首先查找MySql的cnf文件的位置：

[root@flyHome gaoxiang]# find / -iname '*.cnf' -print
/etc/pki/tls/openssl.cnf
/etc/my.cnf
/usr/share/openvpn/easy-rsa/2.0/openssl-0.9.6.cnf
/usr/share/openvpn/easy-rsa/2.0/openssl.cnf
/usr/share/openvpn/easy-rsa/1.0/openssl.cnf
/usr/share/mysql/my-small.cnf
/usr/share/mysql/my-large.cnf
/usr/share/mysql/my-innodb-heavy-4G.cnf
/usr/share/mysql/my-huge.cnf
/usr/share/mysql/my-medium.cnf
/usr/share/doc/mysql-server-5.5.18/my-small.cnf
/usr/share/doc/mysql-server-5.5.18/my-large.cnf
/usr/share/doc/mysql-server-5.5.18/my-innodb-heavy-4G.cnf
/usr/share/doc/mysql-server-5.5.18/my-huge.cnf
/usr/share/doc/mysql-server-5.5.18/my-medium.cnf

?

然后拷贝my-small.cnf、my-medium.cnf、my-huge.cnf、my-innodb-heavy-4G.cnf 其中一个到 /etc/my.cnf 下

[root@flyHome gaoxiang]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y

?

再修改my.cnf

[root@flyHome gaoxiang]# vi /etc/my.cnf

在[client]下添加

default-charater-set=utf8

在[mysqld]下添加
collation_server = utf8_general_ci
character_set_server = utf8

保存退出后重启mysqld：

[root@flyHome gaoxiang]#service mysqld restart

?

完成以上的操作就OK了。

?

看一下效果:

mysql> show variables like 'character_set_%';
+--------------------------+----------------------------+
| Variable_name??????????? | Value????????????????????? |
+--------------------------+----------------------------+
| character_set_client???? | utf8?????????????????????? |
| character_set_connection | utf8?????????????????????? |
| character_set_database?? | utf8?????????????????????? |
| character_set_filesystem | binary???????????????????? |
| character_set_results??? | utf8?????????????????????? |
| character_set_server???? | utf8?????????????????????? |
| character_set_system???? | utf8?????????????????????? |
| character_sets_dir?????? | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
