概述:前面的文章已经大致描述并配置了通过cobbler服务结合PXE+Kickstart+DHCP+TFTP+HTTP无人值守安装多系统的自动化运维安装系统服务;利用这一特性,cobbler还有一个妙用,用来搭建(同步)本好的yum源仓库;用来统一安装更新本地的(IDC)系统软件与第三方软件仓库;
需要用到的无非还是cobbler rsync httpd,本文是线上部署时的整理笔记,旨在备忘与分享,如有错误和遗漏欢迎指正~
安装配置:
由于基于cobbler所以请参考前前方自动化运维之cobbler安装多版本系统
因此只介绍如何基于httpd服务同步更新源,需要安装的cobbler及配置,httpd安装启动好即可配置成本地的更新源;
添加同步及管理本地yum源主要用到cobbler repo 相关命令
cobbler repo命令说明:
# cobbler repo
cobbler repo add #添加yum源
cobbler repo copy
cobbler repo edit
cobbler repo find
cobbler repo list #列出已添加的yum源
cobbler repo remove #删除已添加的本地yum源
cobbler repo rename #重命名本地已添加的源
cobbler repo report #列出全部源的详细信息
添加本地仓库:
cobbler repo add --name=Centos6-UPDATES --mirror=http://mirrors.aliyun.com/centos/6/updates/x86_64/
cobbler repo add --name=Centos6-salt201611 --mirror=https://repo.saltstack.com/yum/redhat/6/x86_64/2016.11/
cobbler repo add --name=Centos7-extras --mirror=https://mirrors.aliyun.com/centos/7/extras/x86_64/
cobbler repo add --name=epel6-x86_64-testing --mirror=http://mirrors.aliyun.com/epel/testing/6/x86_64/
cobbler repo add --name=Centos7-salt201707 --mirror=https://repo.saltstack.com/yum/redhat/7Server/x86_64/2017.7/
cobbler repo add --name=Centos6-Base --mirror=http://mirrors.aliyun.com/centos/6/os/x86_64/
cobbler repo add --name=epel6-x86_64 --mirror=http://mirrors.aliyun.com/epel/6/x86_64/
cobbler repo add --name=Centos7-epel --mirror=https://mirrors.aliyun.com/epel/7Server/x86_64/
cobbler repo add --name=Centos6-webtatic --mirror=http://sp.repo.webtatic.com/yum/el6/x86_64/
cobbler repo add --name=Centos7-webtatic --mirror=https://sp.repo.webtatic.com/yum/el7/x86_64/
cobbler repo add --name=Centos6-percona --mirror=http://repo.percona.com/release/6Server/os/x86_64/
cobbler repo add --name=Centos7-salt201611 --mirror=https://repo.saltstack.com/yum/redhat/7/x86_64/2016.11/
cobbler repo add --name=Centos7-zabbix3 --mirror=http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/
cobbler repo add --name=Centos6-extras --mirror=http://mirrors.aliyun.com/centos/6/extras/x86_64/
cobbler repo add --name=Centos6-zabbix3 --mirror=http://repo.zabbix.com/zabbix/3.4/rhel/6/x86_64/
cobbler repo add --name=Centos7-percona --mirror=http://repo.percona.com/release/7Server/os/x86_64/
查看已经添加的仓库
[root@localhost repo_mirror]# cobbler repo list
Centos6-Base
Centos6-UPDATES
Centos6-extras
Centos6-percona
Centos6-salt201611
Centos6-webtatic
Centos6-zabbix3
Centos7-Base
Centos7-epel
Centos7-extras
Centos7-percona
Centos7-salt201611
Centos7-salt201707
Centos7-webtatic
Centos7-zabbix3
epel6-x86_64
epel6-x86_64-testing
添加好以上各种镜像源后可以通过
#cobbler reposync 命令开始同步所有的镜像源到本地
也可以指定仓库名同步,(cobbler reposync --only=“仓库名”)由于 同步所有需要时间比较长,故这里只指定更新同步一个源做演示,其他的原理一样,以同步Centos7-zabbix3为例
# cobbler reposync --only=Centos7-zabbix3
task started: 2018-06-18_102322_reposync
task started (id=Reposync, time=Mon Jun 18 10:23:22 2018)
hello, reposync
run, reposync, run!
creating: /var/www/cobbler/repo_mirror/Centos7-zabbix3/config.repo
creating: /var/www/cobbler/repo_mirror/Centos7-zabbix3/.origin/Centos7-zabbix3.repo
running: /usr/bin/reposync -l -n -d --config=/var/www/cobbler/repo_mirror/Centos7-zabbix3/.origin/Centos7-zabbix3.repo --repoid=Centos7-zabbix3 --download_path=/var/www/cobbler/repo_mirror -a x86_64
2.9 kB 00:00
3.6 kB 00:00
......以下省略....
由于这个仓库不大同步到本地很快,默认同步到/var/www/cobbler/repo_mirror/下
如图:
此时就可以在浏览器上访问:
http://172.16.0.4/cobbler/repo_mirror/Centos7-zabbix3/ 如图:
制作本地的repo 在其他本地机器上制作
注意:这里的baseurl=http://"ip"/cobbler/repo_mirror/这段是固定的,如果您也是默认安装的httpd,后面的一段指定的方法就是:config.repo所在位置 如zabbix3同步完后config.repo所在目录 Centos7-zabbix3下,因此baseurl=http://172.16.0.4/cobbler/repo_mirror/Centos7-zabbix3/;而同步Centos7-Base时cofig.repo 时所在目录下会有一个Packages用于存放所有的rpm包,baseurl则不应该指到Packages而是:baseurl=http://172.16.0.4/cobbler/repo_mirror/Centos7-Base/
#cat local.repo
[root@localhost yum.repos.d]# cat local.repo
[zabbix-34]
name=local CentOS7 zabbix34
baseurl=http://172.16.0.4/cobbler/repo_mirror/Centos7-zabbix3/
enable=1
gpgcheck=0
[CentoS7-Base]
name=local Centos7 base
baseurl=http://172.16.0.4/cobbler/repo_mirror/Centos7-Base/
enable=1
gpgcheck=0
查看:
# yum clean all
# yum makecache
# yum repolist
如图:
接下来就可以愉快的把这个local.repo分发到所有内部(能访问这个cobbler服务器)机器上,当作zabbix本地源使用了,这里只添加了zabbix,还可以同步以上添加的镜像库,全部同步到本地后制作针对centos6 centos7的本地理更新源!
添加计划任务每天凌晨1点同步所有源到本地(由于基于rsync,同步时自动保持一致)
# crontab -l
1 1 * * * /bin/cobbler reposync >/dev/null
至此一个本地的yum源仓库完成;如果觉得不错点个赞啊!
