CentOS yum源设定使用方法的整理(转)

CentOS yum更新了很多版本更新，我本人认为CentOS yum很好使的文件系统，在此向大家推荐CentOS应该是做为服务器的linux的佼佼者。CentOS采用的二进制包是rpm，不过包的依赖性解决有时候却是个问题。

我比较喜欢debian的apt,非常方便。以前以为RedHat linux没这么方便，后来发现CentOS yum是个不错的东西。CentOS yum的使用和apt有几分相似，这样一来对于许多包的安装就方便多了。

这篇文章主要讲两点内容，一是CentOS yum使用方法的整理;二是找一个比较快的国内的源，这样一来，CentOS yum的大体使用过程就解决了。

1. 1.yum的使用:
2. 1)包的更新
3. 1.1)检查可更新包: yum check-update
4. 1.2)更新所有包: yum update
5. 1.3)更新指定包: yum update package_name
6. 1.4)版本升级: yum upgrade
7. 2)包安装与删除
8. 2.1)yum install package_name
9. 2.2)yum remove package_name
10. 3)包搜索
11. 3.1)搜索特定包: yum search package_name
12. 3.2)搜索包含特定文件名的包:yum provides name
13. 4)包列表
14. 4.1)列出所有安装或更新的包: yum list
15. 4.2)列出指定包:yum list name
16. 4.3)列出可更新包:yum list updates
17. 4.4)列出已安装包:yum list installed
18. 4.5)列出已安装但不包含在资源库中的包:yum list extras

CentOS yum源设定

1. 2.1)加快yum下载速度: yum -y install yum-fastestmirror,在CentOs 4上名字叫做yum-plugin-fastestmirror
2. 2.2)yum源文件:/etc/yum.repos.d/CentOS-Base.repo
3. 2.3)CentOS 5的yum源设为上海交通大学网站
4. CentOS-Base.repo

a.执行64位：rpm –import http://ftp.sjtu.edu.cn/centos/5.0/os/x86_64/RPM-GPG-KEY-CentOS-532位：rpm –import http://ftp.sjtu.edu.cn/centos/5.0/os/i386/RPM-GPG-KEY-CentOS-5b.执行 yum update.2.4)设置CentOS yum源为国内服务器

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