大数据学习第3天---------------------多台机器,利用软连接快速部署yum源
1:如果每台机器一个一个的部署,利用加载iso镜像特别占磁盘空间
下面利用一台机器部署yum源,然后将yum源发布的web服务器,其他虚拟机更改源地址即可
具体;
先挑选一台机器mini4,挂载一个系统光盘到本地目录/mnt/cdrom,然后启动一个httpd服务器,
将/mnt/cdrom 软连接到httpd服务器的/var/www/html目录中 (cd
/var/www/html; ln -s /mnt/cdrom ./centos )
然后通过网页访问测试一下: http://mini4/centos 会看到光盘的目录内容
至此:网络版yum私有仓库已经建立完毕
剩下就是去各台yum的客户端配置这个http地址到repo配置文件中
自己部署下:首先 我192.168.36.197 已经部署好yum源了
下面我吧此yum源 创建软连接,发布到web服务器上(httpd)
[[email protected] html]# mkdir centos
[[email protected] html]# ln -s /mnt/cdrom ./centos
浏览器:http://192.168.36.197/centos/
3:需要配置yum源的机器:
cd /etc/yum.repo.d
[[email protected] yum.repos.d]# rename .repo .repo.bak *
[[email protected] yum.repos.d]# ll

# This repo can be used with mounted DVD media, verify the mount point for
# CentOS-7. You can use this repo and yum to install items directly off the
# DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos too:
# yum --enablerepo=c7-media [command]
#
# or for ONLY the media repo, do this:
#
# yum --disablerepo=\* --enablerepo=c7-media [command]
