Change Yellowdog Updater Modifier (Yum) Repository on CentOS

Hi All, it's really boring to read certification book, and do anything. But If I go home, today I can't reach the goal for today. So I try to open ssh client and access my cent-OS server. When I want to Install pinfo in Cent-OS it's really long.. I think mirror choice server from Kartolo, then after yum clean all, I found from axarva, dionpe, and etc (Kind of server in Indonesia). I want to fix my repository server,  So I try to change my repository and steer static to Kambing server  (another sever in Indonesia).. If it's first time you hear about yum. I'll let you know for a little: Yum is an automatic updater and package installer/remover for rpm systems. It automatically computes dependencies and figures out what things should occur to install packages. for further information please visit: http://yum.baseurl.org/





So the step must we do:
  1. Go to Yum Repo directory, do command this
    $ cd /etc/yum.repos.d/ 
    $ ls -l
    After execute the command, you my find CentOS-Base.repo, the file is contained repo source and I want to modify so I just download repo from kambing repository

  2. Before modify the repository file, do copy first for backup
    $ cp CentOS-Base.repo CentOS-Base.repo.standard

  3. Then modify file CentOS-Base.repo, using vim editor
    $ vim CentOS-Base.repo 
    The output from the command:

  4. Now you can change mirrorlist to baseurl parameter in [base], [updates], [extras] with remove the sharp/hashtag icon and add kambing repo's url. Like below:

    Sample for [base] url on kambing website



    so I change the base url refer to kambing
    # 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.
    #
    #
    
    [centosplus]
    name=Kambing-CentOS-Plus
    #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
    baseurl=http://kambing.ui.ac.id/centos/7.2.1511/centosplus/x86_64/
    enabled=1
    gpgcheck=1
    gpgkey=http://kambing.ui.ac.id/centos/RPM-GPG-KEY-CentOS-7
    
    #released updates
    [updates]
    name=Kambing-CentOS-Updates
    #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
    baseurl=http://kambing.ui.ac.id/centos/7.2.1511/updates/x86_64/
    enabled=1
    gpgcheck=1
    gpgkey=http://kambing.ui.ac.id/centos/RPM-GPG-KEY-CentOS-7
    
    #additional packages that may be useful
    [extras]
    name=Kambing-CentOS-Extras
    #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
    baseurl=http://kambing.ui.ac.id/centos/7.2.1511/extras/x86_64/
    enabled=1
    gpgcheck=1
    gpgkey=http://kambing.ui.ac.id/centos/RPM-GPG-KEY-CentOS-7
    
    After that, add some repo key, that kambing give like fasttrack, OS,
    
    [Fasttrack]
    name=Kambing-CentOS-Fastrack
    baseurl=http://kambing.ui.ac.id/centos/7.2.1511/fasttrack/x86_64/
    enabled=1
    gpgcheck=1
    gpgkey=http://kambing.ui.ac.id/centos/RPM-GPG-KEY-CentOS-7
    
    #released OS
    [OS]
    name=Kambing-CentOS-OS
    baseurl=http://kambing.ui.ac.id/centos/7.2.1511/os/x86_64/
    enabled=1
    gpgcheck=1
    gpgkey=http://kambing.ui.ac.id/centos/RPM-GPG-KEY-CentOS-7
    Then pres Esc button then type :wq
  5. After change repository script, you must clean all cache last repo before. with
    $ yum clean all
    then output should be appear

  6. Then download the list with command
    $ yum list
    When the server directed to kambing.ui, the output should be appear like below:

    No more server reachable information because there is one server to get installed file. 

I Hope it can help you to change your repository in your CentOS
