本地yum库制作及本地安装Docker
生产环境中，我们总是会遇到服务器无法连接外网的情况，这样，如果想安装某个应用，而这个应用依赖的其他类库又特别多，就很痛苦了。这个时候，就需要自己制作个本地的yum库，进行本地安装。本文将以Docker本地安装为例，详细介绍如何制作本地yum库。
1、首先，在能够上网的、与不能上网服务器的Linux发行版本相同的服务器上，执行安装命令，得到安装所需的各种依赖包，如下：

2、下载对应版本的rpm包，网址：
http://rpmfind.net/linux/rpm2html/search.php
3、制作本地yum库。将全部的rpm包拷贝到一个文件夹中，例如docker_rpms，执行如下命令：
[root@localhost test]# ls docker_rpms [root@localhost test]# createrepo . Spawning worker 0 with 18 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@localhost test]# ls docker_rpms repodata
4、编辑docker.repo文件
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-$releasever - Base baseurl=file:///home/dockeryum gpgcheck=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 [update] name=CentOS-$releasever - update baseurl=file:///home/dockeryum gpgcheck=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
5、将docker_rpms文件夹、repodata文件夹、docker.repo拷贝到/home/dockeryum（因为docker.repo文件中做的如此配置）文件夹下。执行如下操作：
[root@localhost home]# ls dockeryum laizy [root@localhost home]# cp -r /etc/yum.repos.d/ /etc/yum.repos.d.bak （备份原始yum源） [root@localhost home]# rm -rf /etc/yum.repos.d/* （清空原始yum源） [root@localhost home]# cp /home/dockeryum/docker.repo /etc/yum.repos.d/ （拷贝自己写的yum源） [root@localhost home]# ll /etc/yum.repos.d/ total 4 -rw-r--r--. 1 root root 682 May 6 10:26 docker.repo [root@localhost home]# yum install libdevmapper* docker （yum安装） Loaded plugins: fastestmirror, langpacks Existing lock /var/run/yum.pid: another copy is running as pid 13870.
