rpm、yum、编译安装轻松管理centos7程序包（21）

四、自建yum仓库

使用createrepo命令建立repodata文件从而处理程序包的依赖关系

    createrepo [options] <directory>

1、创建仓库

# yum install createrepo -y
# ll
total 0
drwxr-xr-x 4 root root 33 Mar 19 21:49 xen4
# ls xen4/
drpms  Packages
# createrepo xen4/
Spawning worker 0 with 159 pkgs
Spawning worker 1 with 159 pkgs

# ls xen4/
drpms  Packages  repodata

2、指向仓库

# cat /etc/yum.repos.d/xen.repo
[xen4]
name=this is a xen
baseurl=file:///opt/xzen4
gpgcheck=0


# yum install xen -y
