默认登录mysql之后show variables like %character% 出现
mysql> show variables like %character%;

找到mysql的配置文件拷贝到etc目录下第一步很重要
使用find命令查找cnf文件记得不要去找f因为它不一定存在而应该找f
[root@linuxserver classes] find / iname f print
/usr/share/doc/mysqlserver/f
/usr/share/doc/mysqlserver/f
/usr/share/doc/mysqlserver/myf
/usr/share/doc/mysqlserver/f
/usr/share/doc/mysqlserver/f
/usr/share/texmf/webc/f
/usr/share/texmf/webc/f
/usr/share/texmf/webc/f
/usr/share/texmf/tex/jadetex/f
/usr/share/ssl/f
找到之后复制一个出来
cp /usr/share/doc/mysqlserver/f /etc/f
打开f修改编码
vi /etc/f
在[client]下增加defaultcharacterset=utf
在[mysqld]下增加defaultcharacterset=utf
同时加上init_connect=SET NAMES utf (设定连接mysql数据库时使用utf编码以让mysql数据库为utf运行)
重新启动mysql执行:sudo /etc/initd/mysql stop 然后sudo /etc/initd/mysql start
mysql> show variables like %character%;

即使做了以上修改如果直接数据库再创建表然后存入中文取出来的会是问号解决的办法是
创建数据库的时候指明默认字符集为utf如
create database test default character set utf;
