CentOS下配置yum本地源服务环境

转载自： http://www.blogjava.net/kxbin/articles/371388.html

本地yum报错提示：

loaded plugins:fastestmirror
loading mirror speeds from cached hostfile
could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=i386&repo=addons error was

解决方法：

环境 vmware + centos5.7
目录 /data/Centos/i386/

1、挂载文件
mkdir -p /mnt/soft
mount -o loop -t iso9660 /dev/cdrom /mnt/soft
cd /data/Centos/i386/

2.新建一个自定义的目录，用来放置你的RPM包，并复制一份。
mkdir -p /data/Centos/i386/
cp -rf /mnt/soft/CentOS/ /data/CentOS/i386/

3.将/mnt/soft下的repodata/ 拷贝到/data/Centos/i386/CentOS下
cp -rf /mnt/soft/repodata/ /data/Centos/i386/CentOS/

4.安装rpm -ivh /mnt/soft/CentOS/createrepo-0.4.11-3.el5.noarch.rpm （此包是用来安装服务端设置软件仓库及信息文件）

5.生成客户端所需的信息文件
createrepo -g /mnt/soft/repodata/comps.xml /data/Centos/i386/

6.将key文件（用于客户端与服务端的认证）拷入指定目录/data/Centos/i386 下
cp /mnt/soft/RPM-GPG-KEY-CentOS-5 /data/Centos/i386/

7.更改yum的配置文件，更改之前CentOS-Base.repo要做好备份
vim CentOS-Base.repo
[base]
name=CentOS5.7-base
baseurl=file:///data/Centos/i386/
enable=1
gpgcheck=1
gpgkey=file:///data/Centos/i386/RPM-GPG-KEY-CentOS-5

先执行下yum clean all

验证结果
[root@lx_web_s1 CentOS]# yum install zlib
