三种方式搭建yum源

1、本地搭建yum源:

[root@Nginx1 x86_64]# vim /etc/yum.repos.d/mnt.repo

[root@Nginx1 x86_64]# cd /etc/yum.repos.d/

[root@Nginx1 yum.repos.d]# ll

total 36

-rw-r--r--. 1 root root 1664 Dec 9 2015 CentOS-Base.repo

-rw-r--r--. 1 root root 1309 Dec 9 2015 CentOS-CR.repo

-rw-r--r--. 1 root root 649 Dec 9 2015 CentOS-Debuginfo.repo

-rw-r--r--. 1 root root 290 Dec 9 2015 CentOS-fasttrack.repo

-rw-r--r--. 1 root root 630 Dec 9 2015 CentOS-Media.repo

-rw-r--r--. 1 root root 1331 Dec 9 2015 CentOS-Sources.repo

-rw-r--r--. 1 root root 1952 Dec 9 2015 CentOS-Vault.repo

-rw-r--r-- 1 root root 57 Sep 6 15:23 mnt.repo

-rw-r--r--. 1 root root 100 Jul 14 05:54 Nginx.repo

[root@Nginx1 yum.repos.d]# pwd

/etc/yum.repos.d

[root@Nginx1 yum.repos.d]#cat/etc/yum.repos.d/mnt.repo

[mnt]
name=mnt
baseurl=file:///mnt
gpgcheck=0
enabled=1

[root@Nginx1 yum.repos.d]# mount /dev/cdrom /mnt/

[root@Nginx1 yum.repos.d]# df -TH

2、阿里云yum源：

centos6.0：

wget-O/etc/yum.repos.d/CentOS-Base.repohttp://mirrors.aliyun.com/repo/Centos-6.repo

centos7.0：

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

运行生成缓存：yum makecache

3、搭建yum服务器

createrepo是yum源维护的工具。

在yum server服务器上面：

yum-yinstallcreaterepo

[root@Nginx1yum.repos.d]#yum-yinstallhttpd
[root@Nginx1yum.repos.d]#systemctlrestarthttpd
[root@Nginx1yum.repos.d]#mkdir-p/var/www/html/centos7.2/x86_64
[root@Nginx1yum.repos.d]#mount/dev/cdrom/mnt/
[root@Nginx1yum.repos.d]#cp-ar/mnt/*/var/www/html/centos7.2/x86_64
[root@Nginx1yum.repos.d]#cd/var/www/html/
[root@Nginx1html]#createrepo-p-d-ocentos7.2/x86_64/centos7.2/x86_64/

在client客户端上面：

[root@host3yum.repos.d]#cattest.repo
[test]
name=test
baseurl=http://172.25.254.130/centos7.2/x86_64
gpgcheck=0
[root@host3yum.repos.d]#
[root@host3yum.repos.d]#yumcleanall
[root@host3yum.repos.d]#yuminstall-yvirt-manager
