使用sohu的网络yum源操作步骤

utydgf

一，下载yum的repo文件：
yum -y install wget
   cd /etc/yum.repos.d/
   wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo

二，将其他的配置文件改名设置备份
mv CentOS-Base.repo CentOS-Base.repo.bak

三，测试yum源可用性
yum list | wc -l
  显示5313个包即为配置正确


配置sohu的网络yum源常见报错：
一，路径错误：
[iyunv@localhost ~]# yum list | wc -l

http://mirrors.sohu.com/centos/6/addons/i386/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Trying other mirror.
http://ftp.jaist.ac.jp/pub/Linux ... epodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Trying other mirror.
解析：
此为配置路径错误

解决办法：
cd /etc/yum.repos.d/
vim  CentOS-Base-sohu.repo
找到addons修改为os即可

然后执行

yum makecache

问题解决。

二，进程占用

[iyunv@localhost yum.repos.d]# yum clean all
Loaded plugins: fastestmirror
Existing lock /var/run/yum.pid: another copy is running as pid 1224.
Another app is currently holding the yum lock; waiting for it to exit...
