linux中yum源在那个目录下,Linux ---各种yum源配置详解
yum,是Yellow dog Updater, Modified 的简称,是杜克大学为了提高RPM 软件包安装性而开发的一种软件包管理器。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RedHat 门下的rpm 了。
yum 主要功能是更方便的添加/删除/更新RPM 包,自动解决包的倚赖性问题,便于管理大量系统的更新问题。
yum 可以同时配置多个资源库(Repository),简洁的配置文件(/etc/yum.conf),自动解决增加或删除rpm 包时遇到的依赖性问题,保持与RPM 数据库的一致性。
(一)yum的安装与卸载
1,查看该系统是否安装yum:[root@localhost ~]# rpm -qa|grep yum
yum-3.2.29-69.el6.centos.noarch
yum-metadata-parser-1.1.2-16.el6.x86_64
yum-plugin-fastestmirror-1.1.30-30.el6.noarch
2,这表示已安装,如果没有安装的话,可以使用系统自带的ISO包来进行安装,一下操作为:[root@localhost ~]# mount /dev/cdrom /mnt
[root@localhost ~]# ll /mnt/Packages/ |grep yum*
-r--r--r--. 3 root root 1019540 Feb 24 2013 yum-3.2.29-40.el6.centos.noarch.rpm
-r--r--r--. 3 root root 27224 Sep 26 2011 yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
-r--r--r--. 3 root root 28220 Jun 25 2012 yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
[root@localhost ~]# rpm -v
3,卸载的步骤为:[root@localhost ~]# rpm -e yum-3.2.29-40.el6.centos.noarch.rpm | yum-metadata-parser-1.1.2-16.el6.x86_64.rpm | yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
[root@localhost ~]# rpm -qa|grep yum
[root@localhost ~]#
(二)yum的配置文件的详解:
yum 的配置文件分为两部分:main 和repositorymain 部分定义了全局配置选项,整个yum 配置文件应该只有一个main。常位于/etc/yum.conf 中。
repository 部分定义了每个源/服务器的具体配置,可以有一到多个。常位于/etc/yum.repo.d 目录下的各文件中。[root@localhost ~]# cat /etc/yum.conf
[main]
cachedir=/var/cache/yum
//yum 缓存的目录,yum 在此存储下载的rpm 包和数据库,默认设置为/var/cache/yum
keepcache=0
//安装完成后是否保留软件包,0为不保留(默认为0),1为保留
debuglevel=2
//Debug 信息输出等级,范围为0-10,缺省为2
logfile=/var/log/yum.log
//yum 日志文件位置。用户可以到/var/log/yum.log 文件去查询过去所做的更新。
pkgpolicy=newest
//包的策略。一共有两个选项,newest 和last,这个作用是如果你设置了多个repository,而同一软件在不同的repository 中同时存在,yum 应该安装哪一个,如果是newest,则yum 会安装最新的那个版本。如果是last,则yum 会将服务器id 以字母表排序,并选择最后的那个服务器上的软件安装。一般都是选newest。
distroverpkg=redhat-release
//指定一个软件包,yum 会根据这个包判断你的发行版本,默认是redhat-release,也可以是安装的任何针对自己发行版的rpm 包。
tolerant=1
//有1和0两个选项,表示yum 是否容忍命令行发生与软件包有关的错误,比如你要安装1,2,3三个包,而其中3此前已经安装了,如果你设为1,则yum 不会出现错误信息。默认是0。
exactarch=1
//有1和0两个选项,设置为1,则yum 只会安装和系统架构匹配的软件包,例如,yum 不会将i686的软件包安装在适合i386的系统中。默认为1。
retries=6
//网络连接发生错误后的重试次数,如果设为0,则会无限重试。默认值为6.
obsoletes=1
//这是一个update 的参数,具体请参阅yum(8),简单的说就是相当于upgrade,允许更新陈旧的RPM包。
plugins=1
//是否启用插件,默认1为允许,0表示不允许。我们一般会用yum-fastestmirror这个插件。
bugtracker_url=http://bugs.centos.org/set_project.php?project_id=16&ref=http://bugs.centos.org/bug_report_page.php?category=yum
# Note: yum-RHN-plugin doesn't honor this.
metadata_expire=1h
installonly_limit = 5
# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d
除了上述之外,还有一些可以添加的选项,如:
exclude=selinux* // 排除某些软件在升级名单之外,可以用通配符,列表中各个项目要用空格隔开,这个对于安装了诸如美化包,中文补丁的朋友特别有用。 gpgcheck=1 // 有1和0两个选择,分别代表是否是否进行gpg(GNU Private Guard) 校验,以确定rpm 包的来源是有效和安全的。这个选项如果设置在[main]部分,则对每个repository 都有效。默认值为0。
(三)配置本地的yum源
1,挂载安装光盘或ISO镜像[root@localhost ~]# mount /dev/cdrom /mnt/
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: /dev/sr0 already mounted or /mnt/ busy
mount: according to mtab, /dev/sr0 is already mounted on /mnt
[root@localhost ~]# ll /mnt/
total 82
-r--r--r--. 1 root root 14 Nov 29 2013 CentOS_BuildTag

-r--r--r--. 1 root root 3380 Nov 29 2013 TRANS.TBL
2,配置本地的yum源:[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ll
total 24
-rw-r--r--. 1 root root 1991 Aug 4 00:13 CentOS-Base.repo
-rw-r--r--. 1 root root 647 Aug 4 00:13 CentOS-Debuginfo.repo
-rw-r--r--. 1 root root 289 Aug 4 00:13 CentOS-fasttrack.repo
-rw-r--r--. 1 root root 630 Aug 4 00:13 CentOS-Media.repo
-rw-r--r--. 1 root root 6259 Aug 4 00:13 CentOS-Vault.repo
[root@localhost yum.repos.d]# vim CentOS-Media.repo
# CentOS-Media.repo
#
# This repo can be used with mounted DVD media, verify the mount point for
# CentOS-6. You can use this repo and yum to install items directly off the
# DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos too:
# yum --enablerepo=c6-media [command]
#
# or for ONLY the media repo, do this:
#
# yum --disablerepo=\* --enablerepo=c6-media [command]
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///mnt/Packages/ #####改成挂载的地址
file:///media/cdrom/
file:///media/cdrecorder/
gpgcheck=1
enabled=1 #####启用本地的yum源
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
-- INSERT --
3,禁用默认的yum网络源,否则会现在网络中寻找合适的包,改名后直接从本地源进行读取[root@localhost yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak
[root@localhost yum.repos.d]#
4,执行yum源更新命令:[root@localhost ~]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: base c6-media extras updates
Cleaning up Everything
Cleaning up list of fastest mirrors
[root@localhost ~]# yum makecache
Loaded plugins: fastestmirror

备注:关于repo 文件的格式
所有repository 服务器设置都应该遵循如下格式:[serverid]
name=Some name for this server
baseurl=url://path/to/repository/serverid 是用于区别各个不同的repository,必须有一个独一无二的名称;
name 是对repository 的描述,支持像$releasever $basearch这样的变量;
baseurl 是服务器设置中最重要的部分,只有设置正确,才能从上面获取软件。它的格式是:baseurl=url://server1/path/to/repository/
url://server2/path/to/repository/
url://server3/path/to/repository/
其中url 支持的协议有 http:// ftp:// file:// 三种。baseurl 后可以跟多个url,你可以自己改为速度比较快的镜像站,但baseurl 只能有一个,也就是说不能像如下格式:baseurl=url://server1/path/to/repository/
baseurl=url://server2/path/to/repository/
baseurl=url://server3/path/to/repository/
其中url 指向的目录必须是这个repository header 目录的上一级,它也支持$releasever $basearch 这样的变量。url 之后可以加上多个选项,如gpgcheck、exclude、failovermethod 等,比如:[updates-released]
name=Fedora Core $releasever - $basearch - Released Updates
baseurl=http://download.atrpms.net/mirrors/fedoracore/updates/$releasever/$basearch
http://redhat.linux.ee/pub/fedora/linux/core/updates/$releasever/$basearch
http://fr2.rpmfind.net/linux/fedora/core/updates/$releasever/$basearch
gpgcheck=1
exclude=gaim
failovermethod=priority
(四)配置国内yum源
系统默认的是国外的yum源,速度较慢,如何使用国内的yum源,以国内网易的163yum源为例:
1,下载repo文件[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost ~]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
2,备份并替换repo文件[root@localhost ~]# mv CentOS-Base.repo CentOS-Base.repo.bak
[root@localhost ~]# mv CentOS6-Base-163.repo CentOS-Base.repo
3,执行yum源更新命令[root@localhost ~]# yum clean all
root@localhost ~]# yum makecache
[root@localhost ~]# yum update
4,导入GPG KEY
yum 可以使用gpg 对包进行校验,确保下载包的完整性,所以我们先要到各个repository 站点找到gpg key(由于我们使用的是163,可以在163官网上下载然后导入即可,下图),一般都会放在首页的醒目位置,一些名字诸如RPM-GPG-KEY-CentOS-5 之类的纯文本文件,把它们下载下来,然后用rpm --import RPM-GPG-KEY-CentOS-6 命令将key 导入
[root@localhost yum.repos.d]# wget http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
--2015-12-24 13:59:16-- http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6

[root@localhost yum.repos.d]# rpm --import RPM-GPG-KEY-CentOS-6
[root@localhost yum.repos.d]#
或者直接把该文件复制到/etc/pki/rpm-gpg/目录下即可[root@localhost yum.repos.d]# cp RPM-GPG-KEY-CentOS-6 /etc/pki/rpm-gpg/
备注:以下是相关的配置文件的解释[root@localhost yum.repos.d]# more CentOS-Base.repo
# CentOS-Base.repo
#
# 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.

关于变量$releasever:代表发行版的版本,从[main]部分的distroverpkg获取,如果没有,则根据redhat-release包进行判断。
$arch:cpu体系,如i686,athlon等
$basearch:cpu的基本体系组,如i686和athlon同属i386,alpha和alphaev6同属alpha。
其他国内yum源列表如下:
(五)使用第三方软件库
Centos/RHEL默认的yum软件仓库非常有限,仅仅限于发行版本那几张盘里面的常规包和一些软件包的更新,利用RpmForge,可以增加非常多的第三方rpm软件包。RpmForge库现在已经拥有超过10000种的CentOS的软件包,被CentOS社区认为是最安全也是最稳定的一个第三方软件库。
1、安装yum-priorities插件
这个插件是用来设置yum在调用软件源时的顺序的。因为官方提供的软件源,都是比较稳定和被推荐使用的。因此,官方源的顺序要高于第三方源的顺序。如何保证这个顺序,就需要安装yum-priorities这插件了。[root@localhost yum.repos.d]# yum install yum-priorities

Complete!
[root@localhost yum.repos.d]#
2、安装完yum-priorities插件后需要设置/etc/yum.repos.d/ 目录下的.repo相关文件(如CentOS-Base.repo),在这些文件中插入顺序指令:priority=N (N为1到99的正整数,数值越小越优先)
一般配置[base], [addons], [updates], [extras] 的priority=1,[CentOSplus], [contrib] 的priority=2,其他第三的软件源为:priority=N (推荐N>10)
以CentOS-Base.repo 为例:[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=http://ftp.sjtu.edu.cn/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
priority=1
3、下载与安装相应rpmforge的rpm文件包[root@localhost yum.repos.d]# wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm

4、安装DAG的PGP Key[root@localhost yum.repos.d]# rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
[root@localhost yum.repos.d]#
5、验证rpmforge的rpm文件包
# rpm -K rpmforge-release-0.5.2-2.el5.rf.*.rpm[root@localhost yum.repos.d]# rpm -K rpmforge-release-0.5.2-2.el5.rf.i386.rpm
rpmforge-release-0.5.2-2.el5.rf.i386.rpm: (sha1) dsa sha1 md5 gpg OK

3,使用vim创建yum repo文件[root@localhost yum.repos.d]# vim CentOS-My.repo
[local] ###指定yum源名
name=my rpm base from local ###yum名字的描述
baseurl= ###指定URL或使用“file://”指定本地路径,注意“/”的数量;
gpgcheck=0 ###不验证来源及package的完整性(由于是本地的文件)
enable=1 ###启用此yum源
4, 清除缓存,并重新构建yum缓存[root@localhost yum.repos.d]# yum clean all ###清除yum缓存
Loaded plugins: fastestmirror, priorities
Cleaning repos: base extras local rpmforge updates
Cleaning up Everything
Cleaning up list of fastest mirrors
[root@localhost yum.repos.d]# yum repolist ###重建yum缓存

备注:yum 常用的操作:
一,yum 常用的操作:
1,yum search keyword(关键字) 搜索
2,yum list (all |installed |recent |updates) 列出全部的,安装的,最近的,软件更新的
3,yum info pachagename 显示指定软件的信息
4,yum whatprovides filename 查询哪个RPM软件包含的目标文件
5,yum remove 软件名 删除yuma安装的软件
二,创建yum仓库简单的步骤:
1,将所有的rpm包拷贝到一个文件夹中
2,通过rpm命令手工安装createrepo软件
3,运行命令createrepo -v /rpm-directory
如果有分组信息,则在运行命令的时候使用-g参数指定分组文件
createrepo -g /tmp/*comps.xml /rpm-directory
4,CentOS/RHEL的分组信息保存在光盘repodata/目录下,文件名以comps.xml结尾的xml文件
创建好之后本机可以通过file方式使用,如果需要作为对外的yum仓库服务器,可以通过http,ftp或nfs协议共享出去。
