西安美林数据怎么样:【yum】自从有了yum，红帽变得好美丽！～

以下文章是转载，虽然内容很多，但我们并不想制作yum。我们只是想可以用yum下载并安装互联网上的软件包，因为红帽没有注册，所以不可以用红帽官方源，但可以用centos的，我在REDHAT5上是这样实现的（相信我）1、首先移动（这里用到是mv 命令，之所以用这个是不想让这两个文件影响下一步的操作）两个文件#mv /etc/yum.conf   /etc/yum.conf.bak#mv /etc/yum.repos.d   /etc/yum.repos.d.bak    注：这个方法并不需要yum.repos.d 目录，为了不让它影响我们，将它换个名字2、vi   /etc/yum.conf 并复制以下代码（这部是重新创建了/etc/yum.conf）[main]

3、 yum update

以下是转载

什么是 yum？yum 是 yellowdog updater modified 的缩写。yellowdog 是一个 Linux 的 distribution，RH 将这种升级技术利用到自己的 distribution 形成了现在的 yum，感觉上 yum 和 apt 的原理类似，但是 apt 是编译代码，执行效率远高于使用 python 写成的 yum。这是 yum 的主页。
   yum 的理念是使用一个中心仓库（repository）管理一部分甚至一个 distribution 的应用程序相互关系，根据计算出来的软件依赖关系进行相关的升级、安装、删除等等操作，减少了 Linux 用户一直头痛的 dependencies 的问题。这一点上，yum 和 apt 相同。apt 原为 debian 的 deb 类型软件管理所使用，但是现在也能用到 RH 门下的 rpm 了。
    一般这类软件通过一个或者多个配置文件描述对应的 repository 的网络地址，通过 http 或者 ftp 协议在需要的时候从 repository 获得必要的信息，下载相关的软件包。这样，本地用户通过建立不同的 repository 的描述说明，在有 Internet 连接时就能方便进行系统的升级维护工作。另外，如果需要使用代理，可以用 http_proxy 和 ftp_proxy 这些 shell 里面标准环境变量的设定。

repository 是用 yum-arch 或者 createrepo 命令创建的，也可以用别人已有的 repository 作为镜像，这里部探讨如何建立一个 repository。

## This file uses a new mirrorlist system developed by Lance Davis for# CentOS.

# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and

# geographically close to the client. You should use this for CentOS# updates

# unless you are manually picking other mirrors.

## If the mirrorlist= does not work for you, as a fall back you can try the

# remarked out baseurl= line instead.

yum配置方案2：寻找互联网上的源

大家都知道rhel想要更新软件都是要注册的，那么我们就不去官网更新！下面配置是前往centos.org和ustc.edu.cn站点更新!

配置rhel 5 使用CentOS的yum站点升级

删除原来的/etc/yum.conf文件和/etc/yum.repo.d目录
rm -rf /etc/yum.conf
cd /etc/yum.repos.d/
rm -rf rhel-debuginfo.repo

vi /etc/yum.conf

到此就ok了，是不是很方便！！！，这个是中科大的源，号称每隔小时跟新一次，速度确实蛮快

测试下

yum -y install system-config-date

ok.................................
