CentOS(Linux)中解决MySQL乱码
[root@Web_Mysql ~]# find / -iname "*.cnf" -print
/usr/share/mysql/my-huge.cnf
/usr/share/mysql/my-small.cnf
/usr/share/mysql/my-innodb-heavy-4G.cnf
/usr/share/mysql/my-medium.cnf
/usr/share/mysql/my-large.cnf
/usr/share/doc/mysql-server-5.1.61/my-huge.cnf
/usr/share/doc/mysql-server-5.1.61/my-small.cnf
/usr/share/doc/mysql-server-5.1.61/my-innodb-heavy-4G.cnf
/usr/share/doc/mysql-server-5.1.61/my-medium.cnf
/usr/share/doc/mysql-server-5.1.61/my-large.cnf
/etc/pki/tls/openssl.cnf
/etc/my.cnf
找到之后，复制一个出来
[root@Web_Mysql ~]# cp /usr/share/doc/mysql-server-5.1.61/my-medium.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y
2. 打开/etc/my.cnf修改配置文件：
[root@Web_Mysql ~]# vim /etc/my.cnf
在[client]下添加
default-character-set=utf8
在[mysqld]下添加
default-character-set=utf8
：wq #保存
3. 重启mysql
根据你安装mysql的方式的不同，采用不用的命令来重启你的mysql。如果你配置过使用mysqld自启动方式，可以执行
[root@Web_Mysql ~]# /etc/rc.d/init.d/mysqld restart
停止 mysqld： [确定]
正在启动 mysqld： [确定]
mysql配置成系统服务的方式，执行
[root@Web_Mysql ~]#service mysqld restart
停止 mysqld： [确定]
正在启动 mysqld： [确定]
4.登录mysql看看修改成功否
[root@Web_Mysql ~]# mysql -u root -p
Enter password: (输入密码)
mysql> show variables like 'character%';
+-----------------------------------------+------------------------------------------+
| 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/ |

配置完成！
