redhat没法注册RHN的解决办法

1.问题

初学Linux,采用边实战nginx边学Linux命令的方式,这样学习的还快还真实一些.固然,问题来的很快.我使用的是redhat,安装pcre就出现了问题,以下:php

 1 [root@localhost ~]# yum install pcre
 2 Loading "security" plugin
 3 Loading "installonlyn" plugin
 4 Loading "rhnplugin" plugin
 5 This system is not registered with RHN.
 6 RHN support will be disabled.
 7 Setting up Install Process
 8 Setting up repositories
 9 No Repositories Available to Set Up
10 Reading repository metadata in from local files
11 Parsing package install arguments
12 Setting up repositories
13 No Repositories Available to Set Up
14 Reading repository metadata in from local files
15 No Match for argument: pcre
16 Nothing to do

从5-6行的描述来看,系统尚未注册RHN.网上查了一下整理到这里,固然你通过本人测试过的.大体过程是从新安装CentOS的yum,卸载Redhat的.好吧,继续node

2.解决问题过程

1)查看redhat版本.python

不一样的redhat版本安装的yum不一样,因此在这里须要先知道linux的版本.使用命令linux

1 cat /etc/issue

个人Linux版本为:nginx

1 Red Hat Enterprise Linux Server release 5.1 (Tikanga)
2 Kernel \r on an \m

2)卸载yum.centos

1 rpm -qa|grep yum|xargs rpm -e --nodeps

执行后等待,后不会有任何提示,不过能够使用命令缓存

1 rpm -qa|grep yum

在卸载先后查看一下yum就能够对比得出,卸载是否有效.app

3)安装yum.ide

从http://mirrors.ustc.edu.cn/centos/(网址可能会发生变化,请网上找最新的版本)找到对应版本的RPM包,进入http://mirrors.ustc.edu.cn/centos/5.1/readme,内容是:学习

1 This directory (and version of CentOS) is depreciated.  For normal users,
2 you should use /5/ and not /5.1/ in your path. Please see this FAQ
3 concerning the CentOS release scheme:
4 
5 http://www.centos.org/modules/smartfaq/faq.php?faqid=34
6 
7 If you know what you are doing, and absolutely want to remain at the 5.1
8 level, go to http://vault.centos.org/ for packages.

大体的意思是使用centos5的版本便可.根据32位仍是64位执行不一样的命令下载便可.

CentOS5
32位版的：
wget http://mirrors.ustc.edu.cn/centos/5/os/i386/CentOS/python-iniparse-0.2.3-6.el5.noarch.rpm
wget http://mirrors.ustc.edu.cn/centos/5/os/i386/CentOS/yum-3.2.22-40.el5.centos.noarch.rpm

wget http://mirrors.ustc.edu.cn/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
64位版的：
wget http://mirrors.ustc.edu.cn/centos/5/os/x86_64/CentOS/python-iniparse-0.2.3-6.el5.noarch.rpm
wget http://mirrors.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-3.2.22-40.el5.centos.noarch.rpm

4)下载yum配置源.

1 mv rhel-debuginfo.repo rhel-debuginfo.repo.bak
2 cd /etc/yum.repos.d
3 wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo

5)生成缓存.

执行命令:

1 yum makecache
