First of all it, my version of centos 7.5
Here I mainly introduce the system by hanging in the image file and specify the network epel mirror source.
First, specify the local disk as a yum repository
1, delete all the files /etc/yum.repos.d
2、
cd / mkdir centos7 mount /dev/cdrom /centos7/
3, then cut into /etc/yum.repos.d directory to create a repo file
cd /etc/yum.repos.d/ vim centos7.repo
4, and then insert the following:
[centos7] name=centos7 baseurl=file:///centos7 enabled=1 gpgcheck=0 #gpgkey=/key/path [root@node01 yum.repos.d]#yum clean all [root@node01 yum.repos.d]#yum list all
5, and then execute the command yum list all
Then create yum use epel source
Then the computer side http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm download file using ftp and uploaded to the server system linux, run the following command as follows:
(During this operation, first run the command ping www.baidu .com, to see if the virtual machine connected to the network, if the ping fails, the venue of this blog https://www.cnblogs.com/xuzhaoyang/p/11239145. HTML .)
rpm -ivh epel-release-latest-7.noarch.rpm yum repolist
At this point, and generates epel.repo epel-testing.repo files, configuration files epel.repo example given here, configured as follows:
name=Extra Packages for Enterprise Linux 7 - $basearch - Source #baseurl=http://download.fedoraproject.org/pub/epel/7/SRPMS metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-source-7&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 gpgcheck=1
The change is not the same place and the same to the above configuration.
After this point epel yum warehouse source configuration, run "yum list all", as shown:
