本地yum源搭建及failed to retrieve解决

第1章 yum是什么

YUM（Yellow dog Updater Modified）为多个Linux发行版的软件包管理器，例如Redhat RHEL,CentOS&Fedoro。YUM主要用于自动安装、升级rpm软件包，它能自动查找并解决rpm包之间的依赖关系。YUM自动下载rpm包并安装。类似某软件的一键安装。

1.1 yum源是什么？

要成功的使用YUM工具安装更新软件或系统，就需要有一个包含各种rpm软件包的repository（软件仓库），这个软件仓库我们习惯称为yum源。网络上有大量的yum源，但由于受到网络环境的限制，导致软件安装耗时过长甚至失败令人难以忍受特别是当有大量服务器大量软件包需要安装时，缓慢的进度条因此我们在优化系统时，都会更换国内的源。相比较而言，本地YUM源服务器最大优点是局域网的快速网络连接和稳定性。有了局域网中的YUM源服务器，即便在Internet连接中断的情况下，也不会影响其他YUM客户端的软件安装和升级。

1.2 yum工作原理

1.2.1 yum配置文件

[root@nfs01yum_bak]# cat /etc/yum.conf[main]定义了全局配置选项cachedir=/var/cache/yum/$basearch/$releaseveryum缓存的目录,存储下载的rpm包和数据库keepcache=0 是否保留安装包0为不保留,1为保留debuglevel=2 debug信息输出等级,默认为2,范围0-10logfile=/var/log/yum.log日志文件位置exactarch=1 update的参数,相当于upgrade,允许更新旧的rpm包obsoletes=1 有1和0两个选择,分别代表是否进行gpg(GNUPrivate Guard)校验,以确定rpm包的来源都是有效和安全的.这个选项如果设置在[main]部分,则对每个repository都有效.默认值 0gpgcheck=1plugins=1 是否启用插件,1表示允许,0不允许installonly_limit=5bugtracker_url=http://bugs.centos.org/set_project.php?project_id=19&ref=http://bugs.centos.org/bug_report_page.php?category=yumdistroverpkg=centos-release 指定一个软件包 # This is the default, if you make this biggeryum won't see if the metadata# is neweron the remote and so you'll "gain" the bandwidth of not having to# downloadthe new metadata and "pay" for it by yum not having correct#information.# It is esp. important, to have correctmetadata, for distributions like# Fedorawhich don't keep old packages around. If you don't like this checking#interupting your command line usage, it's much better to have something# manuallycheck the metadata once an hour (yum-updatesd will do this).#metadata_expire=90m # PUT YOURREPOS HERE OR IN separate files named file.repo# in/etc/yum.repos.d

1.2.2 yum命令用法

1.2.3 查看rpm帮助

1.2.4 查看rpm包信息

[root@m01/server/scripts]# rpm -qpinginx-1.6.3-1.x86_64.rpm Name : nginx Relocations: / Version : 1.6.3 Vendor: root@m01Release : 1 Build Date: 2016年06月26日 星期日 10时57分54秒InstallDate: (not installed) BuildHost: m01Group : default Source RPM:nginx-1.6.3-1.src.rpmSize : 5252902 License: unknownSignature : (none)Packager : <root@m01>URL : http://example.com/no-uri-givenSummary : no description givenDescription:nodescription given

1.2.5 查看rpm包内容

[root@m01~]# rpm -qvl nginx-1.6.3-1.x86_64.rpm packagenginx-1.6.3-1.x86_64.rpm is not installed

1.2.6 查看rpm包的依赖

[root@m01~]# rpm -qpR nginx-1.6.3-1.x86_64.rpm pcre-devel openssl-devel /bin/sh rpmlib(PayloadFilesHavePrefix)<= 4.0-1rpmlib(CompressedFileNames)<= 3.0.4-1

1.2.7 多个rpm包互相依赖强制安装

rpm -Uvh--aid *.rpm或rpm –ivh *.rpm--nodeps --force

1.2.8 查看rpm自带脚本

2.3 镜像同步公网yum源

上面只是将自己制作的rpm包，放入yum源。但还有一种企业需求，说的更具体一点，平时学生上课yum安装软件都是从公网下载的，占用带宽，因此在学校里搭建一个内网yum服务器，但又考虑到学生回家也要使用yum安装软件，如果yum软件的数据库文件repodata不一样，就会有问题。因此我 想到的解决方法就是直接使用公网yum源的repodata。上游yum源必须要支持rsync协议，否则不能使用rsync进行同步。http://mirrors.ustc.edu.cn/status/CentOS官方标准源：rsync://mirrors.ustc.edu.cn/centos/epel源：rsync://mirrors.ustc.edu.cn/epel/

2.3.1 同步命令：

使用rsync同步yum源，为了节省带宽、磁盘和下载时间，我只同步了CentOS6的rpm包，这样所有的rpm包只占用了21G，全部同步需要300G左右。
同步base源，小技巧，我们安装系统的光盘镜像含有部分rpm包，大概3G，这些就不用重新下载。
/usr/bin/rsync-av rsync://mirrors.ustc.edu.cn/centos/6/os/x86_64/ /data/yum_data/centos/6/os/x86_64//usr/bin/rsync-av rsync://mirrors.ustc.edu.cn/centos/6/extras/x86_64/ /data/yum_data/centos/6/extras/x86_64//usr/bin/rsync-av rsync://mirrors.ustc.edu.cn/centos/6/updates/x86_64/ /data/yum_data/centos/6/updates/x86_64/# epel源/usr/bin/rsync-av --exclude=debug rsync://mirrors.ustc.edu.cn/epel/6/x86_64/ /data/yum_data/epel/6/x86_64/

2.3.2 学生使用内网yum源方法

# 可以自建一个内网dns，如果没有，可使用hosts解析。echo'192.168.0.200 mirrors.aliyun.com' >>/etc/hosts

2.3.3 结果展示
