为摆脱ubuntu产生的阴影，果断中午重装Linux redhat enterprise 6.0，下面就开始mysql安装。。各种纠结待续……

[root@localhost kernels]# ls -l /etc/ |grep my
-rw-r--r--.  1 root root    251 Jul 15  2010 my.cnf
-rw-r--r--.  1 root root    251 Nov 26  2013 my.cnf_cp
[root@localhost kernels]# 

查看系统文件，发现系统中my.cnf已经存在

[root@localhost bin]# rpm -qa|grep mysql
mysql-libs-5.1.47-4.el6.i686

查找一下，发现有这个东东，咦……啥东东来着？

download_history  download_history~  mysql-5.5.25.tar.gz
[root@localhost Downloads]# tar -zxv -f mysql-5.5.25.tar.gz 
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Exiting with failure status due to previous errors

安装失败！！肯定是少了个啥东东。。少了这个cmake-2.8.12.1.tar.gz

下载地址：http://www.cmake.org/cmake/resources/software.html

[root@localhost Downloads]# tar-zxv -f cmake-2.8.12.1.tar.gz 

先把这个编译环境装上

[root@localhost cmake-2.8.12.1]# tar -zxv -f mysql-5.5.25.tar.gz 
tar (child): mysql-5.5.25.tar.gz: Cannot open: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now
[root@localhost cmake-2.8.12.1]# 

看上去还是不行，还是换个安装包下载，这个回去看看视频。。这个装的有点抓急，上网一查才知道redhat 6 的在线yum更新是收费的，下面就按照网上介绍的方法，先将系统自带的yum卸载，重新下载再安装。。soga ，copyright 的问题

软件包下载就到网易镜像，貌似好多的：http://mirrors.163.com/centos/6/os/x86_64/Packages/

经过一筐苦心，终于知道，我还是从光盘挂载IOS，再调整yum配置，挂载ing

[root@localhost /]# ls -l |grep cd
[root@localhost /]# ls /dev/ -l |grep cd
lrwxrwxrwx. 1 root root           3 Nov 28 14:36 cdrom1 -> sr0
lrwxrwxrwx. 1 root root           3 Nov 28 14:36 scd0 -> sr0

brw-rw----+ 1 root cdrom    11,   0 Nov 28 14:36 sr0

咦！看来只能挂载sr0，cdrom1是挂载不了的。。

[root@localhost srv]# mount -t auto /dev/sr0 /mnt/cdrom      
mount: block device /dev/sr0 is write-protected, mounting read-only

好啦，下面配置yum配置文档/etc/yum.repos.d/rhel-debuginfo.repo

[root@localhost yum.repos.d]# pwd
/etc/yum.repos.d

[root@localhost yum.repos.d]# vim rhel-debuginfo.repo

[rhel]
name=Install packages from localcate
baseurl=file:///mnt/cdrom
enabled=1
gpgcheck=1

终于，在挂载的光盘下找到了，里面全是i686的包，完全没有i386的rpm包，至此，选择重装centos

[root@localhost Packages]# ls  |grep yum

13天倒计时。。。
