RHEL5.5更改为CentOS的163源

jiel

最近在用RHEL5.5做ISCSI的客户端挂载iscsi盘，但不断出现问题。想更新iscsi-initiator-utils这个包，但又没注册RHN，没办法了，只好换到CentOS源去更新了，我这里选择163的源。

更新源当然要用root用户登录了

GO!去/etc/yum.repos.d/目录

#cd /etc/yum.repos.d/

停用原有的RHEL5.5的RPM源

#mv rhel-debuginfo.repo rhel-debuginfo.repo.bak

如果有其它的源，一律加个.bak

编辑新的163源repo文件

#vi CentOS-Base-163.repo

内容如下：

# CentOS-Base.repo

#

# The mirror system uses the connecting IPaddress of the client and the

# update status of each mirror to pickmirrors that are updated to and

# geographically close to the client.You should use this for CentOS updates

# unless you are manually picking othermirrors.

#

# If the mirrorlist= does not work for you,as a fall back you can try the

# remarked out baseurl= line instead.

网上有些文章会让你去下载wget http://mirrors.163.com/.help/CentOS5-Base-163.repo这个文件，直接有上面的内容了。但可能是人品问题了，下载的文件其中$releasever这个变量死活读不出来，所以把这个变量全部改成了“5”(这是系统的版本，双引号不用)，然后把所有mirrorlist这句都注释了，就是上面这个文件的内容了。

再执行命令：

更改CentOS的163源

#yum clean metadata

#yum makecache

再导入163的key文件

#rpm --import http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-5

到这里就完成了163源的修改了

在这里，你要更新什么包，安装什么包，直接yum就可以了

#yum install iscsi-initiator-utils
