Make local repository and network repository for RHEL6 & telnet enable

创建RHEL6 和 Centos6 的yum 本地源，不过我平时还是喜欢用source包安装。

1、 yum是否安装

[root@heliy ~]# rpm -qa | grep yum

yum-rhn-plugin-0.9.1-5.el6.noarch

 

PackageKit-yum-0.5.8-13.el6.i686
yum-metadata-parser-1.1.2-14.1.el6.i686
yum-utils-1.1.26-11.el6.noarch
yum-3.2.27-14.el6.noarch
PackageKit-yum-plugin-0.5.8-13.el6.i686

2、 挂载

[root@heliy ~]# ls /mnt/
C  dvd1  dvd2  fat32  ISO  ntfs  usb

[root@heliy ~]# cat /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
mount -t ntfs-3g /dev/sda6 /mnt/fat32

#mkdir /home/fukeyun/centosrpm

#cp /mnt/dvd1/Packages/* /homefukeyun/centosrpm

#cp /mnt/dvd2/Packages/* /homefukeyun/centosrpm

/dev/sda6 是我硬盘安装时划分的一个fat32分区，存放RHEL6的安装文件

3、 制作repo文件

可以用createrepo自动生成repo文件

# cd /mnt/fat32/Packages

#createrepo  ./   ##make repomd.xml file

[root@heliy ~]# ls /etc/yum.repos.d/
base.repo  centso6.repo
[root@heliy ~]# cat /etc/yum.repos.d/base.repo
[heliypackages]
name = package
baseurl = file:///mnt/fat32/Packages/
enabled=1
gpgcheck=1
gpgkey=file:///mnt/fat32/RPM-GPG-KEY-redhat-release

[heliyHA]
name = HA
baseurl = file:///mnt/fat32/HighAvailability/
enabled=1
gpgcheck=1
gpgkey=file:///mnt/fat32/RPM-GPG-KEY-redhat-release

[heliyLB]
name = LB
baseurl = file:///mnt/fat32/LoadBalancer/
enabled=1
gpgcheck=1
gpgkey=file:///mnt/fat32/RPM-GPG-KEY-redhat-release

[heliyServer]
name = server
baseurl = file:///mnt/fat32/Server/
enabled=1
gpgcheck=1
gpgkey=file:///mnt/fat32/RPM-GPG-KEY-redhat-release
 

4、监测

[root@heliy ~]# yum repolist

Loaded plugins: refresh-packagekit, rhnpluginThis system is not registered with RHN.RHN support will be disabled.

file:///home/fukeyun/centosrpm/repodata/repomd.xml: [Errno 14] Could not open/read file:///home/fukeyun/centosrpm/repodata/repomd.xml

Trying other mirror.

repo id                                 repo name                         status

heliyHA                                 HA                                   24

heliyLB                                 LB                                    2

heliyServer                             server                            2,646

heliypackages                           package                           2,646

repolist: 5,318

[root@heliy ~]# yum list

报错

Error: Cannot retrieve repository metadata (repomd.xml) for repository: InstallMedia. Please verify its path and try again

用网上的方法：

方法一：删除软件仓库中的 media.repo和/etc/yum.repos.d/packagekit-media.repo （注：如果只删除 packagekit-media.repo是没有用的，之后又会产生新的packagekit-media.repo 文件）

方法二：在/etc/yum.conf增加以下选项

skip_if_unavailable=True

 

方法三：也可直卸载Packagekit 包，yum remove -y PackageKit     但是这样会把gnome-packagekit等7个包一起删了，其它的包我不知道是做什么用的，但gnome-packagekit删掉后肯定无法使用图形界面的“添加/删除软件”了

再次运行yum list ，出现如下错误：

[root@heliy ~]# yum list

Loaded plugins: refresh-packagekit, rhnplugin

This system is not registered with RHN.

RHN support will be disabled.

file:///home/fukeyun/centosrpm/repodata/repomd.xml: [Errno 14] Could not open/read file:///home/fukeyun/centosrpm/repodata/repomd.xml

Trying other mirror.

Error: Cannot retrieve repository metadata (repomd.xml) for repository: heliypackagesdvd1. Please verify its path and try again

这个错误在repolist就有

解决方法：

#mkdir /home/fukeyun/centosrpm/repodata

# cp /mnt/dvd1/repodata/* /home/fukeyun/centosrpm/repodata/

或者用createrepo

#createrepo -p -d -o /home/fukeyun/centosrpm/repodata /home/fukeyun/centosrpm/repodata

createrepo -p -d -o -C --update 常用参数或者到制定目录下createrepo ./创建

这样启动httpd可做为http源，file作为本地源。

上面是本地源,下面将介绍网络源：

参考了这篇：http://www.linuxde.net/2011/10/1578.html

RHEL6用centos6的源安装

1、 删除RHEL6自带的yum 包

     # rpm -aq | grep yum|xargs rpm -e --nodeps

      安装centos6的yum包，在这个URL下载安装：http://mirror.centos.org/centos/6.0/os/i386/Packages,我是下载相关yum的文件，rpm -ivh *.rpm安装，会提示一些depense包，再下载到同一个目录下再安装。

centos官网和国内centos yum镜像站点：

http://mirror.centos.org
http://mirrors.163.com
http://mirrors.btte.net/centos/
http://mirrors.ta139.com/centos/
http://mirror.neu.edu.cn/centos/
http://centos.ustc.edu.cn/centos/
http://mirrors.sohu.com/

http://mirror.tuna.tsinghua.edu.cn/  清华大学开源镜像站

http://mirror.tju.edu.cn/  天津大学开源镜像站

在这些站点的首页都有help，打开这个页面下载repo文件放入/etc/yum.repos.d下

，把文件里面的$releasever全部替换为版本号，即6 或者6.0（具体看站点目录）。

# yum clean all
# yum makecach 或 yum repolist

安装PackageKit这些yum图形界面rpm，而rhn 这些包的错误不许要安装，是我们没有注册即没有购买RedHat许可的原因。
