在配置Linux下MySQL时候主要经历一下步骤:

1、下载rpm,并且安装。问题:在安装完毕server后,出现输入mysql命令出错,,并且在修改密码时候/usr/bin/下没有mysqladmin。解决:没有安装客户端造成。

2、修改密码:mysqladmin -uroot password123456;密码为123456。注意格式。执行成功

3、修改字符集,找了/etc/下,没有找到my.cnf。解决需要拷贝一个/usr/share/下my-huge.cnf ,my-innodb-heavy-4G.cnf ,my-large.cnf ,my-medium.cnf ,my-small.cnf这几个文件,选一个适合你的(针对你服务器的用途),把它copy到/etc下。我选的是my-medium.cnf。

# cp ./my-medium.cnf /etc/my.cnf

给两部分地方添加
[mysql]
default-character-set=utf8
[mysqlId]
default-character-set=utf8

4、重启mysql
/usr/bin/mysqladmin -uroot -p***** shutdown //关闭服务
/etc/init.d/mysql start //启动服务

查看当前编码格式:
mysql> show variables like 'character_set_%';

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

OK。基本上配置成功。
