Installing Control Center

Use this procedure to install Control Center.
  1. Log in to the master host as root, or as a user with superuser privileges.
  2. Install Control Center 1.3.3 from the local repository mirror.
    1. Clean the yum cache and update repository metadata.
      yum clean all && yum makecache fast
    2. Install Control Center.
      yum --disablerepo=\* --enablerepo=zenoss-mirror install -y \
        /opt/zenoss-repo-mirror/serviced-1.3.3-1.x86_64.rpm
  3. Disable automatic startup of Control Center.
    The cluster management software controls the serviced service.
    systemctl disable serviced
  4. Make a backup copy of the Control Center configuration file.
    1. Make a copy of /etc/default/serviced.
      cp /etc/default/serviced /etc/default/serviced-1.3.3-orig
    2. Set the backup file permissions to read-only.
      chmod 0440 /etc/default/serviced-1.3.3-orig
  5. Add a drop-in file for the NFS service.
    This step is a workaround for an an unresolved issue.
    1. Create a directory for the drop-in file.
      mkdir -p /etc/systemd/system/nfs-server.service.d
    2. Create the drop-in file.
      cat <<EOF > /etc/systemd/system/nfs-server.service.d/nfs-server.conf
      [Unit]
      Requires= 
      Requires= network.target proc-fs-nfsd.mount rpcbind.service
      Requires= nfs-mountd.service
      EOF
    3. Reload the systemd manager configuration.
      systemctl daemon-reload
