Efficient yum installation



  1. Make a directory such as /etc/yum/Group, which is shared to all the nodes using NFS.
  2. Download package files:
    • yum groupinstall -y 'Development Tools' --downloadonly --downloaddir=/opt/yum/Group
    • yum update   --downloadonly --downloaddir=/opt/yum/  openmpi openmpi-devel openmpi-devel.x86_64 qt-devel cc gcc-c++ bison ncurses-devel tix.x86_64 glibc-devel flex zlib-devel libXt-devel binutils-devel gcc44 gcc44-c++ zlib-devel
    1. If "--downloadonly" option does not work, then
      • yum install  -y  yum-downloadonly
  3. To install downloaded package at the master as well as compute nodes:
    • yum  localinstall -y /opt/yum/Group/*.rpm 
  4. If you get errors regarding yum execution, try
    • yum clean dbcache
