我们通常使用的是阿里源，搜狐源等，看着这么高大上，有没有想试一试怎么搭建。。。
获得rpm包
可以在网上找到一些rpm包，放到文件夹里面。这里使用光盘里的rpm包。为了速度快，就复制少量的rpm包到文件夹里
[root@CentOS7 ~]# mkdir customrepo
[root@CentOS7 ~]# cp /misc/cd/Packages/tr* ./customrepo/
[root@CentOS7 ~]# ls customrepo/
trace-cmd-2.6.0-3.el7.x86_64.rpm tracker-firefox-plugin-1.2.7-2.el7.x86_64.rpm trousers-0.3.13-1.el7.x86_64.rpm
traceroute-2.0.22-2.el7.x86_64.rpm tracker-needle-1.2.7-2.el7.x86_64.rpm trousers-devel-0.3.13-1.el7.i686.rpm

tracker-devel-1.2.7-2.el7.x86_64.rpm tree-1.6.0-10.el7.x86_64.rpm

注意： 只要有repodata目录，就可以为yum源
生成yum源
[root@CentOS7 ~]# createrepo ./customrepo/
[root@CentOS7 ~]# ls -ld customrepo/repodata/
drwxr-xr-x. 2 root root 4096 Jun 10 17:40 customrepo/repodata/
#查看这个文件夹是否存在
配置yum源
要配置yum源，则需要在/etc/yum.repo.d/中新建以repo结尾的文件，或者在已存在的以repo结尾的文件中写入。此处就在已存在的文件中写入下列几行：
[CentOS7-custom]
name=CentOS-custom
baseurl=file:///root/customrepo/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
验证
[root@CentOS7 ~]# yum repolist
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
repo id repo name status
CentOS7-base CentOS-7-base 9,363
CentOS7-custom CentOS-custom 19
aliyun_epel/7 ailiyun_yum_epel 11,787
aliyun_yum ailiyun_yum 9,363
repolist: 30,532
发现 CentOS-custom 已经存在。下面我安装一下软件
yum install tree --disablerepo=CentOS7-base此处是使用禁用某个默认源
发现可以使用自制的Centos-custom源安装成功
[root@CentOS7 ~]# yum install tree --disablerepo=CentOS7-base
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
