Once the internal repository is setup, configure each SAKA server to communicate with the internal repository for updates. On each SAKA server, follow these steps:

1. Login to this SAKA as the root user through SSH or the console.

2. Change directory to the yum repos folder:

   shell>cd /etc/yum.repos.d

3. Modify the default repository configuration to disable the default repo. Edit CentOS-Base.repo and add the lines highlighted:

   # 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-$releasever - Base
   mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
   #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
   gpgcheck=1
   enabled=0
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
   
   #released updates 
   [updates]
   name=CentOS-$releasever - Updates
   mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra
   #baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
   gpgcheck=1
   enabled=0
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
   
   #additional packages that may be useful
   [extras]
   name=CentOS-$releasever - Extras
   mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra
   #baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
   gpgcheck=1
   enabled=0
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
   
   #additional packages that extend functionality of existing packages
   [centosplus]
   name=CentOS-$releasever - Plus
   mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infra
   #baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/
   gpgcheck=1
   enabled=0
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
   

4. Create a new file called internal.repo. This file will host the configurations for the internal repository. Create the file as follows, replacing <internal-repo> with the FQDN of your internal repository:

   [internal-base]
   name=Internal CentOS-$releasever - Base
   baseurl=http://<internal-repo>/centos/$releasever/os/$basearch/
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
   
   #released updates 
   [internal-updates]
   name=Internal CentOS-$releasever - Updates
   baseurl=http://<internal-repo>/centos/$releasever/updates/$basearch/
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

5. Clear the yum cache with the following command:

   shell> yum clean all

6. Check whether SAKA is configured properly and if it can connect to the internal repository by running the following command:

   shell> yum repolist

7. If everything is working correctly, the command returns output similar to the following:

   shell> Loading mirror speeds from cached hostfile
   internal-base                                                                                                                                                                                                                                                      
   internal-updates                                                                                                                                                                                                                                                   
   repo id                         repo name                                                                                           
   internal-base                   Internal CentOS-7 - Base                                                                            
   internal-updates                Internal CentOS-7 – Updates

   A PYCURL ERROR indicates SAKA could not connect to the internal repository. Check that there are no routing issues or firewall issues and try again.

Now SAKA is configured to receive yum updates through the internal repository. Update this SAKA through the command yum update.

Remember that before making any updates to production appliances, make updates to your development/test appliance first. As part of the regression process, try restarting the development/test appliance and run any regression tests to confirm sane operations after the restart. A regression on the development/test appliance is absolutely required before updating production appliances.
