IMG 1010 - GCEMS - Install Required Packages

This should all be done as a root user.

• Install packages via CentOS Repository \(follow this step if an internet connection is accessible on CentOS server).

  [root]# yum install compat\-libstdc\++\-33.i686 kexec\-tools fipscheck device\-mapper\-multipath sgpio perl\-Convert\-ASN1 python\-dmidecode imake emacs libsane\-hpaio tftp\-server freeradius festival audit net\-snmp\-utils mesa\-libGLU\-devel xorg\-x11\-utils httpd vsftpd dhcp tigervnc* wireshark wireshark\-gnome ksh

• Install packages via local Yum Repository (follow the steps below if an internet connection is not accessible on CentOS server).

  • Build a local repository, Download the Everything ISO.
    https://www.centos.org/download

• Mount your CentOS 7 installation DVD. For example, let us mount the installation media on /mnt directory.

• The CentOS installation DVD is mounted under /mnt directory. Next install vsftpd package and let the packages available over FTP to your local clients.
  Change to /mnt/Packages directory.

   

  Install vsftpd package, for instance.

  • Enable and start vsftpd service.

  • Create a storage location in our FTP server pub directory.

  • Install "createrepo" package, for instance.

  • Copy all the files from CentOS DVD(s) (i.e., from /mnt/Packages/ directory to the "localrepo" directory).

  • Once you copied all the files, create a repository file called "localrepo.repo" under /etc/yum.repos.d/ directory and add the following lines into the file. You can name this file as per your preference.

  • Add the following lines:

    Use three slashes (///) in the baseurl.

  • Start building local repository.

  • Clean the yum cache and update the repository lists.

  • Alternatively, you can install packages only from the local repository by mentioning the repository as shown below.
