RHEL AS5.1软件安装小结

outmylife

近来本打算在机上安装apache httpd的rpm包，使用rpm -ivh 命令安装时发现与很多包有依赖关系，这样一个包一个包安装且不说嫌麻烦况且也不知道那个先那个后；后来转变思路rpm不行，俺用下载个tar.gz压缩包自己编译呗，运行./configure命令发现机上没有gcc，通过rpm -ivh gcc时又发现包的相互依赖，感觉不甚其烦。在网上google发现有yum这个好东西，我把使用yum的一些心得小结如下，以下配置实现软件的在线安装。
1.yum安装
  在RHEL AS5.1的安装光盘中自带有yum的rpm包，运行rpm -ivh yum.****.rpm 即可。或者安装前通过rpm -qi yum命令查看下。
2.yum配置
  安装后，其配置文件位于/etc/yum.conf,通过vi yum.conf打开配置文件并末尾处添加以下内容

1. 
   
2. [Base]
   
3. name=as5-base
   
4. baseurl=http://centos.ustc.edu.cn/centos/5/os/$basearch
   
5. gpgcheck=1
   
6. gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

  由于RHEL AS系统升级为收费服务，所以无法使用RHEL自身的yum源进行软件安装和升级，但由于centos与RHEL系统几乎相差无几，所以对RHEL进行软件安装和升级时可使用centos的yum源。RHEL AS5.1yum的配置除更改yum.conf文件外还可在/etc/yum.repos.d下新建一个*.repo文件，把以上代码内容粘贴于此文件中而不用改动yum.conf文件,在以上代码中‘$basearch’表示电脑架构，PC的为I386。作此配置可实现软件的安装，如要实现系统升级需在配置[updates]项，完整repo配置文件内容如下。

1. 
   
2. # CentOS-Base.repo
   
3. #
   
4. # This file uses a new mirrorlist system developed by Lance Davis for CentOS.
   
5. # The mirror system uses the connecting IP address of the client and the
   
6. # update status of each mirror to pick mirrors that are updated to and
   
7. # geographically close to the client.  You should use this for CentOS updates
   
8. # unless you are manually picking other mirrors.
   
9. #
   
10. # If the mirrorlist= does not work for you, as a fall back you can try the
    
11. # remarked out baseurl= line instead.
    
12. #

如果我用的是rhel5.2的话，现在centos只到5.1，这样的话如何yum呢？
