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.repo http://mirrors.aliyun.com/repo/Centos-6.repo

centos7.0：

wget -O /etc/yum.repos.d/CentOS-Base.repo http://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 -y install createrepo

[root@nginx1 yum.repos.d]# yum -y install httpd
[root@nginx1 yum.repos.d]# systemctl restart httpd
[root@nginx1 yum.repos.d]# mkdir -p /var/www/html/centos7.2/x86_64
[root@nginx1 yum.repos.d]# mount /dev/cdrom /mnt/
[root@nginx1 yum.repos.d]# cp -ar /mnt/* /var/www/html/centos7.2/x86_64
[root@nginx1 yum.repos.d]# cd /var/www/html/
[root@nginx1 html]#createrepo -p -d -o centos7.2/x86_64/ centos7.2/x86_64/

在client客户端上面：

[root@host3 yum.repos.d]# cat test.repo
[test]
name=test
baseurl=http://172.25.254.130/centos7.2/x86_64
gpgcheck=0
[root@host3 yum.repos.d]#
[root@host3 yum.repos.d]# yum clean all
[root@host3 yum.repos.d]# yum install -y virt-manager……………………………………………………………………mesa-libEGL.x86_64 0:10.6.5-3.20150824.el7  mesa-libGL.x86_64 0:10.mesa-libgbm.x86_64 0:10.6.5-3.20150824.el7  mesa-libglapi.x86_64 nmap-ncat.x86_64 2:6.40-7.el7               pango.x86_64 0:1.36.8pixman.x86_64 0:0.32.6-3.el7                pulseaudio-libs.x86_6pulseaudio-libs-glib2.x86_64 0:6.0-7.el7    pycairo.x86_64 0:1.8.pygobject3.x86_64 0:3.14.0-3.el7            python-ipaddr.noarch rest.x86_64 0:0.7.92-3.el7                  spice-glib.x86_64 0:0spice-gtk3.x86_64 0:0.26-5.el7              unbound-libs.x86_64 0usbredir.x86_64 0:0.6-7.el7                 virt-manager-common.nvte-profile.x86_64 0:0.38.3-2.el7           vte3.x86_64 0:0.36.4-Complete!
