自动化部署必备技能—搭建YUM仓库
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。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。特别是当有大量服务器大量软件包需要安装时，缓慢的进度条令人难以忍受。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。
1.1 服务端配置
mkdir -p
/application/yum/centos6/x86_64/ ß1.创建yum仓库目录,rpm包都上至此目录
yum -y install createrepo ß2.安装createrepo软件
createrepo -pdo
/application/yum/centos6/x86_64/ /application/yum/centos6/x86_64/ ß3.初始化repodata索引文件
cd /application/yum/centos6/x86_64/ ß4.进入需要提供仓库的目录
python -m SimpleHTTPServer 80 &>/dev/null & ß5.可以用Apache或nginx提供web服务，但用Python的http模块更简单，适用于内网环境, 可以通过浏览器输入本机IP查看。
createrepo –update /application/yum/centos6/x86_64/ ß6.每加入一个rpm包就要更新一下
sed -i ‘s#keepcache=0#keepcache=1#g’
/etc/yum.conf ß修改yum配置文件keepacache=0改为1，保存下载过的软件
cachedir=/var/cache/yum/$basearch/$releasever ß安装包存储目录=
/var/cache/yum/x86_64/6/base/packages
1.2客户端配置
cd /etc/yum.repos.d
[root@B yum.repos.d]# vi oldboy.repo ß连接本地yum源
[xuliangwei]
name=Server
baseurl=http://10.0.0.5
enable=1
gpgcheck=0
[root@YUM ~]# yum
–-enablerepo=xuliangwei –disablerepo=base,extras,updates,epel list ß指定使用xuliangwei库(临时生效)
或：
|
1 |
<span class="comment">yum</span> <span class="comment">install</span> <span class="literal">-</span><span class="literal">-</span><span class="comment">disablerepo=\*</span> <span class="literal">-</span><span class="literal">-</span><span class="comment">enablerepo=Local</span> <span class="comment">php</span><span class="literal">-</span><span class="comment">fpm</span> |
[root@oldboy yum.repos.d]# vim
/etc/yum.repos.d/CentOS-Base.repo
# 在每一个启动的源加上
# enabled=0#改为1就启用，没有此参数也是启用。
[base]
…………
enabled=0
[updates]
…………
enabled=0
[extras]
…………
enabled=0
# 还有其他开启的仓库就使用这个办法关闭
2.Yum服务配置文件
2.1全局配置文件
main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，位于/etc/yum.cof
[root@XuBuSi ~]# cat /etc/yum.conf
[main]
cachedir=/var/cache/yum/$basearch/$releasever ßyum缓存的目录，存储下载的rpm包和数据库
keepcache=0 ß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 ßDebug信息输出等级，范围为0-10，缺省为2
logfile=/var/log/yum.log ß日志文件位置
exactarch=1 ß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。
obsoletes=1 ß update的参数，相当于upgrade，允许更新陈旧的RPM包。
gpgcheck=1 ß
plugins=1 ß是否启用插件，默认1为允许，0表示不允许
installonly_limit=5
bugtracker_url=http://bugs.centos.org/set_project.php?project_id=16&ref=http://bugs.centos.org/bug_report_page.php?category=yum
distroverpkg=centos-release ß指定一个软件包，yum会根据这个包判断发行版本
2.2yum仓库配置文件
repository部分定义了每个源服务器的具体配置，可以有一到多个，位于/etc/yum.repos.d/目录下的各文件中
[root@XuBuSi ~]# ll /etc/yum.repos.d/
CentOS-Base.repo ß网络源的配置文件
CentOS-Media.repo ß本地源的配置文件
epel.repo ß第三方源的配置文件
2.3配置本地yum源
[root@XuBuSi ~]# grep -v “^#”
/etc/yum.repos.d/CentOS-Media.repo
[c6-media]
name=CentOS-$releasever – Media
baseurl=file:///media/CentOS/
file:///media/cdrom/ ß修改为/mnt/cdrom(即为光盘挂载点)
file:///media/cdrecorder/
gpgcheck=1
enabled=0 ß改为1就启动，没有此参数也是启用。
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
#当然也可以像上面自己写一个文件,然后指定为下载点即可。
3.企业yum仓库搭建实战
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。
镜像同步公网yum源上游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/
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/
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。

=====================================================
搭建CentOS在线yum源镜像服务器
说明：
操作系统：CentOS 6.x
IP地址：192.168.21.188
实现目的：同步CentOS镜像站点的内容到此服务器，并且通过配置http服务器，能够向外提供yum服务
准备篇：
一、安装http服务器
这里使用Nginx服务器提供http服务
关于Nginx服务器搭建，参考：CentOS安装配置LNMP服务器（Nginx+PHP+MySQL）
http://www.osyunwei.com/archives/5910.html
二、系统约定
Nginx站点根目录:/usr/local/nginx/html
服务器执行脚本文件存放目录:/home/crontab
三、开始Nginx目录浏览功能
vi /usr/local/nginx/conf/nginx.conf #编辑配置文件，在http {下面添加以下内容：
autoindex on; #开启nginx目录浏览功能
autoindex_exact_size off; #文件大小从KB开始显示
autoindex_localtime on; #显示文件修改时间为服务器本地时间
:wq! #保存，退出
service nginx reload #重新加载配置
http://www.osyunwei.com/archives/5051.html

安装篇：
一、创建镜像文件存放目录
mkdir -p /usr/local/nginx/html/centos #CentOS官方标准源
mkdir -p /usr/local/nginx/html/repoforge #第三方rpmforge源
mkdir -p /usr/local/nginx/html/epel #第三方epel源
说明：这里创建三个文件夹，分别存放CentOS官方标准源、第三方的rpmforge源和epel源
二、确定以上三个yum源上游源的同步镜像地址
1、CentOS官方标准源：rsync://mirrors.ustc.edu.cn/centos/
2、rpmforge源：rsync://mirrors.ispros.com.bd/repoforge/
3、epel源：rsync://mirrors.ustc.edu.cn/epel/
备注：上游yum源必须要支持rsync协议，否则不能使用rsync进行同步。
参考：
CentOS官方标准源：
rsync://mirrors.kernel.org/centos
rpmforge源：
http://apt.sw.be/
rsync://ftp-stud.fht-esslingen.de/dag
epel源：
http://mirrors.fedoraproject.org/publiclist/EPEL/
rsync://mirrors.kernel.org/fedora-epel
三、创建以上三个yum源同步脚本，并且设定脚本自动执行
mkdir -p /home/crontab #创建目录
vi /home/crontab/yum_rsync.sh #添加以下代码
#!/bin/sh
/usr/bin/rsync -avrt rsync://mirrors.ustc.edu.cn/centos/ –exclude-from=/usr/local/nginx/html/exclude_centos.list /usr/local/nginx/html/centos/
/usr/bin/rsync -avrt rsync://mirrors.ispros.com.bd/repoforge/ –exclude-from=/usr/local/nginx/html/exclude_repoforge.list /usr/local/nginx/html/repoforge/
/usr/bin/rsync -avrt rsync://mirrors.ustc.edu.cn/epel/ –exclude-from=/usr/local/nginx/html/exclude_epel.list /usr/local/nginx/html/epel/
:wq! #保存退出
chmod +x /home/crontab/yum_rsync.sh #添加脚本执行权限
备注：运行此脚本前，先要创建好同步目录及不需要同步的目录列表文件
cd /usr/local/nginx/html/ #进入目录
touch exclude_centos.list #创建文件
touch exclude_repoforge.list #创建文件
touch exclude_epel.list #创建文件
把不需要同步的目录写到上面对应的文件中，每行一个目录
例如：
vi exclude_epel.list
4/
4AS/
4ES/
4WS/
:wq! #保存退出
四、添加脚本定时执行任务
vi /etc/crontab #在最后一行添加以下代码
0 1 * * * root /home/crontab/yum_rsync.sh #设置每天凌晨1点整开始执行脚本
:wq! #保存退出
service crond restart #重启
测试篇：
一、安装rsync同步软件
yum install rsync xinetd #安装
vi /etc/xinetd.d/rsync #编辑配置文件，设置开机启动rsync
disable = no #修改为
/etc/init.d/xinetd start #启动（CentOS中是以xinetd 来管理Rsync服务的）
:wq! #保存退出
二、执行同步脚本
sh /home/crontab/yum_rsync.sh
注意：等待脚本执行完毕，首次同步，耗费的时间比较长！
三、根据不同版本创建三个yum源的repo配置文件
cd /etc/yum.repos.d/ #进入目录
mv /etc/yum.repos.d/CentOS-Base.repo CentOS-Base.repo-bak
1、CentOS官方标准源：
CentOS 5.x系列：
vi /etc/yum.repos.d/CentOS-Base.repo #添加以下代码
# 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.

四、测试yum源是否配置正确
1、当前系统版本为CentOS 6.x，以此为例
cd /etc/yum.repos.d/
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
vi CentOS-Base.repo #添加以下代码
# 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.

yum clean all #清除当前yum缓存
yum makecache #缓存yum源中的软件包信息
yum repolist #列出yum源中可用的软件包
2、使用yum命令安装软件
yum install php #测试CentOS官方标准源
yum install htop #测试rpmforge源
yum install nginx #测试epel源
至此，搭建CentOS在线yum源镜像服务器完成！
