搭建内网yum源
阅读(2,238)
一：因内网服务器 众多，当统一安装一些比较大的rpm的时候全部从外网下载就比较慢，而且还占用了一定的出口流量，因此在内网部署了一台yum服务器，将阿里云的epel源、zabbix、Base等定时镜像到一台单独的内网服务器，然后将其他内网服务器的yum地址全部指向此服务器以加快内网安装rpm包的速度，具体如下：
1.1：以镜像阿里云的zabbix 3.0 rhel7的yum源为例，先安装cobbler命令，然后添加repo源：
[root@aqdl repo_mirror]# cobbler repo add --name=zabbix --mirror=http://mirrors.aliyun.com/zabbix/zabbix/3.0/rhel/7/x86_64/ --arch=x86_64 --breed=yum #添加repo文件
[root@aqdl repo_mirror]# cobbler reposync #执行同步
task started: 2017-02-14_044922_reposync
task started (id=Reposync, time=Tue Feb 14 04:49:22 2017)
hello, reposync
run, reposync, run!
creating: /var/www/cobbler/repo_mirror/zabbix/config.repo
creating: /var/www/cobbler/repo_mirror/zabbix/.origin/zabbix.repo #其实就是通过命令/usr/bin/reporsync 进行的同步
running: /usr/bin/reposync -l -n -d --config=/var/www/cobbler/repo_mirror/zabbix/.origin/zabbix.repo --repoid=zabbix --download_path=/var/www/cobbler/repo_mirror -a x86_64

1.2：查看同步后的目录：
[root@aqdl ~]# ls /var/www/cobbler/repo_mirror/zabbix/
cache

repodata

zabbix-web-mysql-3.0.7-1.el7.noarch.rpm
zabbix-web-pgsql-3.0.7-1.el7.noarch.rpm
1.3：使用一台内网服务器配置yum源进行测试：
[root@bogon ~]# vim /etc/yum.repos.d/zabbix.repo
[local-zabbix]
name=local zabbix
baseurl=http://192.168.10.100/cobbler/repo_mirror/zabbix/ #cobbler服务器的地址，zabbix目录为镜像的阿里的zabbix源
enabled=1
gpgcheck=0
1.4：验证安装zabbix 客户端：
[root@bogon ~]# yum install zabbix-agent
Loaded plugins: fastestmirror, langpacks

1.5：设置定时任务计划，每天晚上2点定时更新:
0 2 * * * cobbler reposync &> /dev/null
1.6：epel源及base源等配置方法同上，如下：
[root@aqdl ~]# cobbler repo add --name=epel --mirror=https://mirrors.aliyun.com/epel/7/x86_64/ --arch=x86_64 --breed=yum
[root@aqdl ~]# cobbler repo add --name=saltstack --mirror=http://repo.saltstack.com/yum/redhat/latest/x86_64/latest/ --arch=x86_64 --breed=yum
[root@aqdl ~]# cobbler repo add --name=openstack-mitaka --mirror=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-mitaka/ --arch=x86_64 --breed=yum
[root@aqdl ~]# cobbler repo add --name=updates --mirror=https://mirrors.aliyun.com/centos/7/updates/x86_64/ --arch=x86_64 --breed=yum
[root@aqdl ~]# cobbler repo add --name=extras --mirror=https://mirrors.aliyun.com/centos/7/extras/x86_64/ --arch=x86_64 --breed=yum
[root@aqdl ~]# cobbler repo add --name=os --mirror=https://mirrors.aliyun.com/centos/7/os/x86_64/ --arch=x86_64 --breed=yum
[root@aqdl ~]# cobbler reposync #在夜深人静的时候同步效果显著！
1.7：验证最同步后的仓库大小并通过浏览器访问方库：
1.7.1：最终同步后的大小：
[root@aqdl ~]# cd /var/www/cobbler/repo_mirror/
[root@aqdl repo_mirror]# du -sh ./* #以下只包含centos 7的yum仓库
12G ./epel
527M ./extras
583M ./openstack-mitaka
7.4G ./os
27M ./saltstack
1.3G ./updates
11M ./zabbix
1.7.2：通过浏览器验证效果：
1.8：在内网服务器使用内网的yum源安装openstack进行测试能否正常安装：
1.8.1：内网yum源配置：
