Linux配置自建 YUM 软件存储库

yum软件仓库的搭建方式有三种，分别是本地yum源，网络yum源，第三方软件仓库。

以下示例演示了搭建本地yum仓库的方法：

1. 删除 /etc/yum.repos.d/dvd.repo 这个仓库文件

[root@desktop1 ~]# ll /etc/yum.repos.d/
total 8
-rw-r--r--. 1 root root  84 Sep 27 20:20 dvd.repo
-r--r--r--. 1 root root 114 Oct 30  2015 packagekit-media.repo
[root@desktop1 ~]# rm -f /etc/yum.repos.d/dvd.repo 

2.运行yum repolist，确保当前的电脑中没有yum仓库 

[root@desktop1 ~]# yum repolist 
Loaded plugins: langpacks
repolist: 0

3. 使用 yum-config-manager 工具，创建一个仓库文件，软件包的目录为本地主机文件系统 中的:/rhel7/dvd

[root@desktop1 ~]# yum-config-manager --add-repo=file:///rhel7/dvd
Loaded plugins: langpacks
adding repo from: file:///rhel7/dvd

[rhel7_dvd]
name=added from: file:///rhel7/dvd
baseurl=file:///rhel7/dvd
enabled=1

4. 再次查看／etc/repos.d／中已经有了新的软件仓库

[root@desktop1 ~]# ll /etc/yum.repos.d/
total 8
-r--r--r--. 1 root root 114 Oct 30  2015 packagekit-media.repo
-rw-r--r--. 1 root root  85 Nov  2 16:41 rhel7_dvd.repo

5. 编辑仓库文件rhel7_dvd.repo，确保 repo id 为“LOCAL_RHEL7”,repo name 为“LOCAL_REPO” 

　　原始文件：

[rhel7_dvd]
name=added from: file:///rhel7/dvd
baseurl=file:///rhel7/dvd
enabled=1

　　更改后：

[root@desktop1 ~]# cat /etc/yum.repos.d/rhel7_dvd.repo 

[LOCAL_RHEL7]
name=LOCAL_REPO

gpgcheck=1
gpgkey=file:///rhel7/dvd/RPM-GPG-KEY-redhat-release

6. 使用 yum repolist 确保上一步骤的更改已生效 

[root@desktop1 ~]# yum repolist
Loaded plugins: langpacks
LOCAL_RHEL7                                                                                | 4.1 kB  00:00:00     
(1/2): LOCAL_RHEL7/group_gz                                                                | 134 kB  00:00:00     
(2/2): LOCAL_RHEL7/primary_db                                                              | 3.4 MB  00:00:00     
repo id                                               repo name                                             status
LOCAL_RHEL7                                           LOCAL_REPO                                            4,305
repolist: 4,305

7. 尝试安装 bind 这个软件包，确认你的 YUM 仓库可以使用 

[root@desktop1 ~]# yum -y install bind
Loaded plugins: langpacks
