yum源仓库搭建

系统：centos7

一、安装nginx

yum install -y nginx

yum  install -y createrepo   安装建yum源仓库的工具，可以用来建立yum仓库
yum  install  -y yum-plugin-priorities 安装控制yum源更新优先级工具，这个工具可以用来控制进行yum源检索的先后顺序，建议可以用在client端。

二、配置nginx

/etc/nginx/nginx.conf

server{

listen ;
autoindex on;

autoindex_exact_size on;

autoindex_localtime on;

}

默认index路径/usr/share/nginx/html

那么在html下面建立以下目录：

mkdir -p /usr/share/nginx/html/CentOS-YUM/CentOS/version_6./64bit/

mkdir -p /usr/share/nginx/html/CentOS-YUM/CentOS/version_7./64bit/

mkdir -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_6./64bit/

mkdir -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_7./64bit/

且不要忘记给目录增加可读和可执行权限，否则在web页面显示不出来。

chmod -R +x  /usr/share/nginx/html/

在web的index.html首页里面添加指向文件目录的超链接：

<p style="font-weight:bolder;color:green;font-size:30px;">ALL of the packages in the below:</p>
<br/>

<a href="http://159.138.1.77/CentOS-YUM/Aliyun">Aliyun</a><br/>

These packagers from of CentOS ISO.<br/>

<a href="http://159.138.1.77/CentOS-YUM/CentOS">CentOS</a><br/>

These packagers from of "Internet service provider".<br/>

<p style="font-weight:bolder;color:red;font-size:18px;">Please replace the file and fill in the following content:</p>
<p style="font-weight:bolder;color:blue;font-size:15px;">Way: /etc/yum.repos.d/CentOS-Base.repo</p>

重启nginx

systemctl restart nginx

三、修改当前系统yum来源repo文件

1.首先对此文件进行备份

cp -p /etc/yum.repos.d/CentOS-Base.repo    /etc/yum.repos.d/CentOS-Base.repo.bak

2.接下来去阿里云的官方网站下载阿里云的CentOS-Base.repo文件,如下所示：

mkdir -p /etc/yum.repos.d/Aliyun
wget -O /etc/yum.repos.d/Aliyun/CentOS-6.repo http://mirrors.aliyun.com/repo/Centos-6.repo

wget -O /etc/yum.repos.d/Aliyun/CentOS-7.repo http://mirrors.aliyun.com/repo/Centos-7.repo

四、进行同步脚本的创建并执行同步

vim /etc/yum.repos.d/yum.reposync.sh

#!/bin/bash

reposync -p /usr/share/nginx/html/CentOS-YUM/CentOS/version_7./64bit/

/usr/bin/sed -i "s/7/6/g" `grep  -rl /etc/yum.repos.d/CentOS-Base.repo`

reposync -p /usr/share/nginx/html/CentOS-YUM/CentOS/version_6./64bit/

cat /etc/yum.repos.d/Aliyun/CentOS-.repo > /etc/yum.repos.d/CentOS-Base.repo

reposync -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_6./64bit/

/usr/bin/sed -i "s/6/7/g" `grep  -rl /etc/yum.repos.d/CentOS-Base.repo`

reposync -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_7./64bit/

cat /etc/yum.repos.d/CentOS-Base.repo.bak > /etc/yum.repos.d/CentOS-Base.repo

chmod +x  /etc/yum.repos.d/yum.reposync.sh

然后执行脚本

sh /etc/yum.repos.d/yum.reposync.sh

createrepo -p /usr/share/nginx/html/CentOS-YUM/CentOS/version_6./64bit/base/Packages

createrepo -p /usr/share/nginx/html/CentOS-YUM/CentOS/version_7./64bit/base/Packages

createrepo -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_6./64bit/base/Packages

createrepo -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_7./64bit/base/Packages

当yum源仓库建立好以后，会在对应的目录下面出现“repodata”的目录。如下图所示：

五、客户端Client的yum配置：

1、安装优先级软件：

yum install -y yum-plugin-priorities

2.首先对client端的/etc/yum.repos.d/目录下的repo文件进行更改。

mkdir –p /etc/yum.repos.d/back

mv /etc/yum.repos.d/* /etc/yum.repos.d/back/

vim /etc/yum.repos.d/CentOS-Base.repo
[mylocal]

name=source_from_localserver  #这里是整合到server端的centos6的光盘镜像yum源

baseurl=http://http://159.138.1.77/centos/6.6/x86_64/Packagers/

gpgcheck=

enable=

priority=    #这里的priority就是上面安装的优先级工具，设定从小到大

[Aliyun_6.6_base]

name=source_from_localserver

baseurl=http://159.138.1.77/CentOS-YUM/Aliyun/version_6.6/64bit/base/Packages

gpgcheck=

enable=

priority=

[Centos_6.6_base]

name=source_from_localserver

baseurl=http://159.138.1.77/CentOS-YUM/CentOS/version_6.6/64bit/base/Packages

gpgcheck=

enable=

priority=

[Aliyun_6.6_extras]

name=source_from_localserver

baseurl=http://159.138.1.77/CentOS-YUM/Aliyun/version_6.6/64bit/extras/Packages

gpgcheck=

enable=

priority=

[Centos_6.6_extras]

name=source_from_localserver

baseurl=http://159.138.1.77/CentOS-YUM/CentOS/version_6.6/64bit/extras/Packages

gpgcheck=

enable=

priority=

[Aliyun_6.6_updates]

name=source_from_localserver

baseurl=http://159.138.1.77/CentOS-YUM/Aliyun/version_6.6/64bit/updates/Packages

gpgcheck=

enable=

priority=

[Centos_6.6_updates]

name=source_from_localserver

baseurl=http://159.138.1.77/CentOS-YUM/CentOS/version_6.6/64bit/updates/Packages

gpgcheck=

enable=

priority=

---------------------

 3.然后进行本利的缓存的清理和建立

yum clean all

yum makecache

yum repolist 
yum源仓库搭建

当缓存建立好以后，就可以在client端直接使用yum进行安装软件包了。而检索的顺序就是根据优先级来的。

六、配置server端的yum源自动更新机制

 1.首先来写一个bash脚本在/home/crontab/下，这个脚本的作用说白了就是通过一条一条自动执行，最终达到，自动更新yum源的目的，代码如下：

vim /home/crontab/oderforrepo.sh
#!bin/bash

/usr/bin/reposync -np /usr/share/nginx/html/CentOS-YUM/CentOS/version_7./64bit/

/usr/bin/sed -i "s/7/6/g" `grep  -rl /etc/yum.repos.d/CentOS-Base.repo`

/usr/bin/reposync -np /usr/share/nginx/html/CentOS-YUM/CentOS/version_6./64bit/

cat /etc/yum.repos.d/CentOS-Base.aliyun.repo.bak > /etc/yum.repos.d/CentOS-Base.repo

/usr/bin/reposync -np /usr/share/nginx/html/CentOS-YUM/Aliyun/version_6./64bit/

/usr/bin/sed -i "s/6/7/g" `grep  -rl /etc/yum.repos.d/CentOS-Base.repo`

/usr/bin/reposync -np /usr/share/nginx/html/CentOS-YUM/Aliyun/version_7./64bit/

cat /etc/yum.repos.d/CentOS-Base.repo.bak > /etc/yum.repos.d/CentOS-Base.repo

“-np”的意思为仅仅更新新更新的软件到指定目录

其他的跟第四步的语句是一个意思。

 2、然后再来添加定时计划：

vim /etc/crontab

  * *  rootrun-parts /home/crontab/oderforrepo.sh

这个定时任务表示：每周6的晚上凌晨2点开始执行oderforrepo.sh的脚本.

这样就可以自动更新yum源了。

最后记得查看本地系统的系统时间，如果觉得有必要可以将时间同步。
