产生这个文档，是因为在家里的虚拟机（32位）上，RHEL6环境yum安装MySQL非常不顺利。在公司的64位一体机上，打算在虚拟机上再试一次。没想到，寻找RHEL6的yum源配置文件，反而成了麻烦。

从昨天中午到下午4点，包括这篇文档的雏形才算基本完成。找了不少网络资料，太多不靠谱。我是根据文中的提到的2篇“参考资料”才完成的。
yum配置，从2011年秋天学RHCE的时候，就一直是我的痛点。现在，通过光盘挂载配置yum源应该没有问题。但是，通过Internet配置yum……虽然反复折腾多次，但好像没有太多的进步。
把这篇文档整理出来，希望在日后再遇到类似的问题，可以照猫画虎，先把问题解决再说。
1.删除redhat原有的
[root@nagios ~]# yum rpm -aq|grep yum|xargs rpm -e --nodeps Command line error: no such option: -a error: package Usage: is not installed error: package [options] is not installed error: package COMMAND is not installed error: package shell is not installed error: package Run is not installed error: package an is not installed error: package interactive is not installed error: package shell is not installed
2.下载yum安装文件
注意：最好自己到镜像站点（如：http://mirrors.163.com/centos/6/os/x86_64/）找相应的包，这里列出来的包名称，过段时间可能会过时。
[root@nagios ~]# wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm --2014-09-04 22:46:55-- http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm 正在解析主机 mirrors.163.com... 123.58.173.106 正在连接 mirrors.163.com|123.58.173.106|:80... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：1019540 (996K) [application/x-redhat-package-manager] 正在保存至: “yum-3.2.29-40.el6.centos.noarch.rpm” 100%[==========================================================================================================================================================>] 1,019,540 1.43M/s in 0.7s 2014-09-04 22:46:57 (1.43 MB/s) - 已保存 “yum-3.2.29-40.el6.centos.noarch.rpm” [1019540/1019540]) [root@nagios ~]# wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm --2014-09-04 22:47:20-- http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm 正在解析主机 mirrors.163.com... 123.58.173.106 正在连接 mirrors.163.com|123.58.173.106|:80... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：27224 (27K) [application/x-redhat-package-manager] 正在保存至: “yum-metadata-parser-1.1.2-16.el6.x86_64.rpm” 100%[==========================================================================================================================================================>] 27,224 --.-K/s in 0.08s 2014-09-04 22:47:20 (343 KB/s) - 已保存 “yum-metadata-parser-1.1.2-16.el6.x86_64.rpm” [27224/27224]) [root@nagios ~]# wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm --2014-09-04 22:48:15-- http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm 正在解析主机 mirrors.163.com... 123.58.173.106 正在连接 mirrors.163.com|123.58.173.106|:80... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：28220 (28K) [application/x-redhat-package-manager] 正在保存至: “yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm” 100%[==========================================================================================================================================================>] 28,220 --.-K/s in 0.05s 2014-09-04 22:48:15 (611 KB/s) - 已保存 “yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm” [28220/28220]) [root@nagios ~]# wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm --2014-09-04 22:49:42-- http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm 正在解析主机 mirrors.163.com... 123.58.173.106 正在连接 mirrors.163.com|123.58.173.106|:80... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：37052 (36K) [application/x-redhat-package-manager] 正在保存至: “python-iniparse-0.3.1-2.1.el6.noarch.rpm” 100%[==========================================================================================================================================================>] 37,052 88.7K/s in 0.4s 2014-09-04 22:49:43 (88.7 KB/s) - 已保存 “python-iniparse-0.3.1-2.1.el6.noarch.rpm” [37052/37052])
这里使用的是网易镜像，在这里可以找到你想要的，不一定要用CentOS的软件包。
3.安装yum，必须按照顺序
[root@nagios ~]# rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm warning: python-iniparse-0.3.1-2.1.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY Preparing... ########################################### [100%] package python-iniparse-0.3.1-2.1.el6.noarch is already installed [root@nagios ~]# rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm warning: yum-metadata-parser-1.1.2-16.el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY Preparing... ########################################### [100%] file /usr/lib64/python2.6/site-packages/_sqlitecache.so from install of yum-metadata-parser-1.1.2-16.el6.x86_64 conflicts with file from package yum-metadata-parser-1.1.2-14.1.el6.x86_64 file /usr/lib64/python2.6/site-packages/sqlitecachec.pyc from install of yum-metadata-parser-1.1.2-16.el6.x86_64 conflicts with file from package yum-metadata-parser-1.1.2-14.1.el6.x86_64 [root@nagios ~]# rpm -ivh yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm warning: yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY Preparing... ########################################### [100%] 1:yum-plugin-fastestmirro########################################### [100%]
注意：最后两个包必需同时安装，否则会相互依赖。
[root@nagios ~]# rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm warning: yum-3.2.29-40.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY Preparing... ########################################### [100%] file /etc/bash_completion.d/yum.bash from install of yum-3.2.29-40.el6.centos.noarch conflicts with file from package yum-3.2.27-14.el6.noarch file /etc/yum.conf from install of yum-3.2.29-40.el6.centos.noarch conflicts with file from package yum-3.2.27-14.el6.noarch file /usr/lib/python2.6/site-packages/yum/__init__.py from install of yum-3.2.29-40.el6.centos.noarch conflicts with file from package yum-3.2.27-14.el6.noarch ……其它输出略……
4.将CentOS 6的仓库作为yum源
[root@nagios ~]# cd /etc/yum.repos.d/ [root@nagios yum.repos.d]# ll 总用量 0
通过这次配置发现，yum源的名称不重要，只要保证后缀是“.repo”即可。
[root@nagios yum.repos.d]# cat 163.repo [base] #yum源的名称 name=CentOS-$releasever - Base #这个yum源的名称，在做kicakstart时需要特别注意 baseurl=http://mirrors.163.com/centos/6/os/$basearch/ #yum源地址：如果是本地源，“file:///”中的第3个“/”表示本地根目录 enable=1 #不启用这个yum源为“0”，启用安全校验为“1” gpgcheck=1 #不启用安全校验为“0”，启动安全校验为“1” gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6 #安全校验，检测这个yum源的rpm包是否为红帽官方包导入gpgkey #released updates [updates] name=CentOS-$releasever - Updates baseurl=http://mirrors.163.com/centos/6/updates/$basearch/ enable=1 gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6 #packages used/produced in the build but not released #[addons] #name=CentOS-$releasever - Addons #baseurl=http://mirrors.163.com/centos/$releasever/addons/$basearch/ #gpgcheck=1 #gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras baseurl=http://mirrors.163.com/centos/6/extras/$basearch/ enable=1 gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus baseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/ gpgcheck=1 enabled=0

5.清除yum的缓存（命令“yum clean all”）
6.yum安装mysql

安装失败，提示好像是没有更多的yum源地址。
更换另1个yum源配置文件，安装也失败。
[root@nagios yum.repos.d]# yum -y install mysql-server Loaded plugins: fastestmirror, refresh-packagekit, rhnplugin This system is not registered with RHN. RHN support will be disabled.

再次使用第1个yum源配置文件“163.repo”，安装成功。不过，安装过程中，还是有错误出现。
