Re: RadosGW - Multiple instances on same host

Thanks guys!

Doing this I’ll need have a load balancer in front of instances (like haproxy, nginx, etc…) to to redirect requests to each instance right?

Override 'rgw frontends' for each instance as well.
Eg:
rgw frontends = civetweb port=7480
rgw frontends = civetweb port=7481

The default value is:
rgw frontends = fastcgi, civetweb port=7480

Hello Somnath,

I’ve create the files, one for each instance but when I restart the radosgw I see the message bellow on radosgw logs:

2015-06-24 18:46:47.567711 7f30190e3780 0 civetweb: 0xaed360: set_ports_option: cannot bind to 7480: 98 (Address already in use)

Could you show how did you do that with civetweb?

Regards.

Hi Italo,
What we did was with civetweb and each RGW instances will be running with its own civetweb instances I guess.
Now, it seems you are trying to run multiple fastcgi external servers with single apache instance. This should work but I never tried and I am not sure how apache load balanced between those.
I think along with the different fcgi file, you need to create separate rgw conf file within /etc/apache2/sites-available .
Thanks & Regards

Thanks Somnath,
In this case I’ll need create a ceph.conf like bellow Also, I’ll need to create two different .fcgi files on /var/www/ one for each instance, as same with the apache config, right?
[client.radosgw.instance-01]
host = hostname
keyring = /etc/ceph/ceph.client.radosgw.instance-01.keyring
rgw socket path = /var/run/ceph/ceph.radosgw.instance-01.fastcgi.sock
log file = /var/log/radosgw/client.radosgw.log
rgw dns name = instance-01.mydomain
rgw enable apis = s3, admin
rgw enable ops log = true
[client.radosgw.instance-02]
host = hostname
keyring = /etc/ceph/ceph.client.radosgw.instance-02.keyring
rgw socket path = /var/run/ceph/ceph.radosgw.instance-02.fastcgi.sock
log file = /var/log/radosgw/client.radosgw.log
rgw dns name = instance-02.mydomain
rgw enable apis = s3, admin
rgw enable ops log = true
At.

Yes, it is possible. Each RGW instance is very cpu intensive, make sure you don’t run out of cpu though. Also, each one will be having its own webserver in front so you need a LB in front.
Thanks & Regards
