Updating Control Center on master hosts

Use this procedure to update Control Center on both master hosts to version 1.5.0.
  1. Log in to the master host as root, or as a user with superuser privileges.
  2. Save the current serviced configuration file as a reference.
    1. Rename the file.
      mv /etc/default/serviced /etc/default/serviced-pre-1.5.0
    2. Set permissions to read-only.
      chmod 0440 /etc/default/serviced-pre-1.5.0
  3. Install the new version of Control Center.
    yum install --enablerepo=zenoss-mirror \
    If yum returns an error due to dependency issues, see Resolving package dependency conflicts for potential resolutions.
  4. Make a backup copy of the new configuration file.
    1. Copy the file.
      cp /etc/default/serviced /etc/default/serviced-1.5.0-orig
    2. Set permissions to read-only.
      chmod 0440 /etc/default/serviced-1.5.0-orig
  5. Display the settings of the reference configuration file.
    grep -E '^\b*[A-Z_]+' /etc/default/serviced-pre-1.5.0
  6. Open the new configuration file with a text editor, and then update the file for your environment.
