另一种善后处理:卸载后 /var/lib/mysql 中的 /etc/my.cnf 会重命名为 my.cnf.rpmsave,/var/log/mysqld.log 会重命名为 /var/log/mysqld.log.rpmsave,如果确定没用后就手工删除。

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in ‘/root/.mysql_secret‘.
You must change that password on your first connect,
no other statement but ‘SET PASSWORD‘ will be accepted.
See the manual for the semantics of the ‘password expired‘ flag.
Also, the account for the anonymous user has been removed.
In addition, you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
See the manual for more instructions.
Please report any problems at
http://bugs.mysql.com/ The latest information about MySQL is available on the web at
http://www.mysql.com Support MySQL by buying support/licenses at
http://shop.mysql.com New default config file was created as /usr/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
3)检测 MySQL 3306 端口是否安打开。测试是否成功可运行 netstat 看 MySQL 端口是否打开,如打开表示服务已经启动,安装成功。MySQL 默认的端口是3306。

1:MySQL-client ^C########################################### [100%] 安装完成
MySQL安装完成后不像 SQL Server 默认安装在一个目录,它的数据库文件、配置文件和命令文件分别在不同的目录,了解这些目录非常重要,尤其对于Linux的初学者,因为 Linux本身的目录结构就比较复杂,如果搞不清楚MySQL的安装目录那就无从谈起深入学习。
6)更改 MySQL 目录。由于MySQL数据库目录占用磁盘比较大,而MySQL默认的数据文件存储目录为 /"var/lib/mysql",也可以把要把数据目录移到 "/" 根目录下的 "mysql_data" 目录中(如果做测试用就不用移动了)。
MySQL默认用户名为"root",此处的"root"与Linux的最高权限用户"root"不是一会儿,而且默认的用户"root"的密码为空,所以上图中让输入密码,直接点击回车即可。
如果"/etc/"目录下没有my.cnf配置文件,请到 "/usr/share/mysql/" 下找到 my-default.cnf 文件,拷贝其中一个合适的配置文件到 "/etc/" 并改名为 "my.cnf" 中。命令如下:
