解决方案：

第一步  解决错误

yum运行时提示被锁住了解决办法

1、当大家用linux的yum时，是不是经常会遇到下面的情况

Loaded plugins: fastestmirror

Existing lock /var/run/yum.pid: another copy is running as pid 3404.

Another app is currently holding the yum lock; waiting for it to exit...

The other application is: yum

Memory : 41 M RSS (253 MB VSZ)

Started: Wed Apr 11 07:03:37 2012 - 00:25 ago

State : Sleeping, pid: 3404

没关系，两条语句就可以搞定它。

2、[[email protected] ~]# rm -r /var/run/yum.pid

rm：是否删除 一般文件 “/var/run/yum.pid”? y

[[email protected] ~]# /sbin/service yum-updatesd restart

停止 yum-updatesd： [确定]

启动 yum-updatesd： [确定]

3、[[email protected] ~]# yum install gcc*

搞定！！！

第二步 再进行安装yum

[[email protected] ~]# yum repolist                 #此命令不仅是安装yum的命令 还可以对yum进行更新

第三步  安装、备份与更新yum源

资源网站：http://mirrors.aliyun.com

备份yum源：

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

下载yum源：

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

下载epel源

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

小结：

yum repolist

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

yum -y install sl                   #进行安装需要的软件
