    tar zxvf cephlib.tar.gz
\cp cephlib/* /opt/gcache/lib/
  5. Assign a permission for the directory.

    chmod 550  /opt/gcache/lib/*

    cp /etc/ceph/ceph.conf /opt/gcache/ceph/
cp /etc/ceph/ceph.client.admin.keyring /opt/gcache/ceph/
chown globalcache:globalcache -R /opt/gcache/ceph/

    After the RPM package is installed, an /opt/gcache directory is generated. The server programs and configuration files are stored in the /opt/gcache/bin and /opt/gcache/conf directories respectively.
