Re: Problem with radosgw

Hi,
first checks you can do:
- Check the RADOSGW process is running
- Check the output of ceph auth list for typos in permissions for the RADOSGW user
- Check you have the keyring file for the user you created on the RADOSGW node
- Check the output of ceph df to verify the RADOSGW was able to create its pools
- Check the execute permission on the FCGI script file
- Check the content of your ceph.conf file on the RADOSGW node and check for typos.

Feel free to post the result of those checks (ceph.conf file, ls -l, ceph df output, ps -ef | grep radosgw output) remove any key

I use CentOS 7 on all nodes. Also I can not start radosgw with this command:
systemctl start ceph-radosgw
because it shows:
Failed to start ceph-radosgw.service: Unit ceph-radosgw.service failed to load: No such file or directory.

But this command seems to work:
systemctl start ceph-radosgw@radosgw.gateway.service

httpd and ceph-radosgw@radosgw.gateway service is: active (running)

Please help me to figure out how to repair it.
