Install rpm package directly via yum/rpm

We can copy the rpm file to compute node and install it via rpm/yum. If the package is likely to be there in the yum repository of rocks then it call also be installed via yum directly. For example: 

ssh <compute-node-hostname>
yum -y install iotop


Install rpm package via rocks build process

We can add package to rocks compute node installation process. This way all new compute nodes will automatically get this package also during initial OS installation itself. To achieve this use:

  1. Edit '/etc/yum.conf' and enable 
    keepcache=1
  2. Go to /etc/yum.repos.d folder and enable required repositories. For example edit '/etc/yum.repos.d/epel.repo' and set 
    enabled =1
  3. Install or reinstall the package so that its rpms are downloaded and available in yum-cache. If you have the rpm via other mechanism then that is also fine. 
    yum -y reinstall vim
    

    yum -y install htop
    If rpm is obtained from other mechanisms perhaps try "yum localinstall" of that rpm on a compute node to validate all dependencies before adding it to build process.
  4. Go to folder where we need to keep all custom rpm files and copy the new rpm files there 
    cd "/export/rocks/install/contrib/7.0/x86_64/RPMS/"
    

    cp /var/cache/yum/x86_64/7/Rocks-7.0/packages/vim-enhanced-7.4.160-2.el7.x86_64.rpm .
    

    cp /var/cache/yum/x86_64/7/epel/packages/htop-2.2.0-3.el7.x86_64.rpm .
  5. Create extend-compute.xml file using: 
    cd /export/rocks/install/site-profiles/7.0/nodes/
    

    cp skeleton.xml extend-compute.xml
  6. Edit 'extend-compute.xml' and list all the package rpms that are copied. We need to list all the packages one by one. 
    <package>vim-enhanced</package>
    

    <package>htop</package>
  7. Rebuild the compute node distribution 
    cd /export/rocks/install/
    

    rocks create distro
  8. Test the build on a compute node (one where these packages are not installed yet) 
    rocks set host boot <compute-node-hostname> action=install
    

    ssh <compute-node-hostname> "shutdown -r now"
