这两天安装nginx的时候需要安装openssl-devel和pcre-devel
感觉使用yum的时候超慢，有没有什么办法可以更改成国内的镜像站点或者使用本地已经下载下来的文件呢？
答案是肯定的 ^_^
一、使用yum源为国内镜像：
1、备份/etc/yum.repos.d/CentOS-Base.repo文件
然后修改为如下：

[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=http://mirror.be10.com/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirror.be10.com/centos/RPM-GPG-KEY-CentOS-5

#released updates
[updates]
name=CentOS-$releasever - Updates
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
baseurl=http://mirror.be10.com/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=http://mirror.be10.com/centos/RPM-GPG-KEY-CentOS-5

#packages used/produced in the build but not released
[addons]
name=CentOS-$releasever - Addons
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=addons
baseurl=http://mirror.be10.com/centos/$releasever/addons/$basearch/
gpgcheck=1
gpgkey=http://mirror.be10.com/centos/RPM-GPG-KEY-CentOS-5

#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
baseurl=http://mirror.be10.com/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=http://mirror.be10.com/centos/RPM-GPG-KEY-CentOS-5

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus
baseurl=http://mirror.be10.com/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.be10.com/centos/RPM-GPG-KEY-CentOS-5

2、执行rpm –import http://mirror.be10.com/centos/RPM-GPG-KEY-CentOS-5

二、CentOS 下使用本地镜像源
如果你已经下载了centos的DVD或者多CD版本，那好办，解压i386目录到本地的目录，比如/pkgstore/CentOS而CentOS已经在/etc/yum.repos.d下面创建了CentOS-Media.repo，对该文件做适应修改就可以使用。以下是修改结果

[root@localhost etc]# cat yum.repos.d/CentOS-Media.repo
# CentOS-Media.repo
#
# This repo is used to mount the default locations for a CDROM / DVD on
# CentOS-5. You can use this repo and yum to install items directly off the
# DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos to
# yum –enablerepo=c4-media [command]
#
# or for ONLY the media repo, do this:
#
# yum –disablerepo=\* –enablerepo=c4-media [command]

[c5-media]
name=CentOS-$releasever - Media
baseurl=file:///pkgstore/CentOS
# file:///media/cdrom/
# file:///media/cdrecorder/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-beta

现在就可以使用yum check-update来测验一下本地源了。如果在没有连接网络情况，最好把yum.repos.d目录下面的其它repo文件适当更名，这样yum就只使用本地源，速度得以提升。
