如何把镜像站的资源弄到本地

我们设置yum后，发现安装程序经常网络原因下载很慢，要不就是直接下载到一半GG，所以搞个本地的yum还是非常重要的

1.安装rpm包构建工具

yum install createrepo yum-utils

2.移除不用的yum源

[root@localhost yum.repos.d]# mv /etc/yum.repos.d/CentOS-* /opt/
[root@localhost yum.repos.d]# ls

3.创建你自己需要下载到本地的yum

我这里拿openstack-pike为列，使用的是阿里的镜像站提供的源

vi pike.repo

[pike]
name=pike
baseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-pike/
gpgcheck=0
enabled=1

删除那些不用的yum只是为了不要混了，现在 /etc/yum.repo/ 下面就只有一个源了

[root@localhost yum.repos.d]# ls
pike.repo

4.清理一下，然后查看当前的yum

[root@localhost yum.repos.d]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: pike
Cleaning up everything

你会发现有一个pike的源，就是我们刚刚创建的

[root@localhost yum.repos.d]# yum repolist
Loaded plugins: fastestmirror
pike                                                                                                                           | 2.9 kB  00:00:00     
pike/primary_db                                                                                                                | 927 kB  00:00:00

pike                                                                     pike                                                                   2,182
repolist: 2,182

5.缓存到本地

reposync -r [你要缓存下来的那个源的名字]

[root@localhost yum.repos.d]# reposync -r pike
(1/2182): GitPython-1.0.1-5.el7.noarch.rpm                                                                                     | 501 kB  00:00:00

6.创建索引，很重要如果不创建就无法使用

进入刚刚缓存下来的文件夹中，执行createrepo .

[root@localhost yum.repos.d]# cd pike
[root@localhost pike]# createrepo .
Spawning worker 0 with 2182 pkgs
Workers Finished
Saving Primary metadata
Saving file lists metadata
Saving other metadata
Generating sqlite DBs
Sqlite DBs complete

执行完上诉命令命令会生成一个叫repodata的文件夹，可以去看看

[root@localhost pike]# cd repodata/
[root@localhost repodata]# ls
00007899bb2ef33f791537ad8b4bf7668affe30251cec2ce433b6d1512e7d0e0-filelists.xml.gz

7.本地源完成，你要怎么用自己看着办，也可以打包传出来耍

tar -zcvf pike.tar.gz pike#打包压缩
tar -zxvf pike.tar.gz#解压缩
