REDHAT YUM本地源的搭建和使用

yum源一般分为两种,本地yum源和本地网络yum源,前者是通过文件提供安装包,后者是通过网络下载安装包;

由于Redhat7.3的yum源需要注册付费,所以往往会出现下载yum源安装包失败,如下图:

(1)上传安装包

把Redhat的安装包传到root下某个路径;

(2)挂载镜像文件

进入到安装包的目录,执行:

mount -o loop rhel-server-7.3-x86_64-dvd.iso /cdrom

(3)复制镜像文件

#最好选择空间较大的路径

执行:

cp -r /cdrom /* /opt/yum/rhel-server-7.3-x86_64-dvd

(4)生成repodata

cd /opt/yum/rhel-server-7.3-x86_64-dvd 
createrepo . 

会在/opt/yum/rhel-server-7.3-x86_64-dvd下生成repodata文件夹,下面有filelists.xml.gz other.xml.gz primary.xml.gz repomd.xml这些文件

(5)配置客户端/etc/yum.repos.d/源配置文件, 创建rhel-source.repo

[root@redhat73 selinux]# cd /etc/yum.repos.d/
[root@redhat73 yum.repos.d]# ls
dave.repo.bak  epel.repo.bak  epel-testing.repo.bak  redhat.repo  redhat.repo.bak  rhel-source.repo
[root@redhat73 yum.repos.d]# more rhel-source.repo 
[rhel-source]
baseurl=file:///opt/yum/rhel-server-7.3-x86_64-dvd
enabled=1
gpgcheck=0 
gpgkey=file:///opt/yum/rhel-server-7.3-x86_64-dvd/RPM-GPG-KEY-redhat-release

(6)搭建的过程中出现的问题

运行createrepo .出错,下面是出错的信息

[root@localhost rhel-server-7.3-x86_64-dvd]# createrepo .

Traceback (most recent call last):

  File "/usr/share/createrepo/genpkgmetadata.py", line 28, in 

    import createrepo

  File "/usr/lib/python2.7/site-packages/createrepo/__init__.py", line 21, in 

    import yumbased

  File "/usr/lib/python2.7/site-packages/createrepo/yumbased.py", line 27, in 

    from yum.packages import YumLocalPackage

ImportError: No module named yum.packages

解决方法:

执行了以下三条命令安装createrepo:

[root@localhost Packages]# rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
[root@localhost Packages]# rpm -ivh yum-3.4.3-150.el7.noarch.rpm
[root@localhost Packages]# rpm -ivh createrepo-0.9.9-26.el7.noarch.rpm

最后执行createrepo .命令
