CeTune broke at haproxy step for CentOS nodes

[ksingh7]

Hello guys ,
I am running CeTune on CentOS nodes and got stuck at haproxy step. On RHEL based machines there is no /etc/default/haproxy configuration file so CeTune fails , is this a known issue ?

BTW haproxy rpm is properly installed on these nodes

As a temporary fix i created a dummy file /etc/default/haproxyand it worked

In addition to that i am also seeing problems with haproxy service restart by CeTune

hi, @ksingh7 , deploy rgw part is quite hard coded, to make sure everything goes well after running 'deploy rgw', we add haproxy configuration and restart, but which only works on debian(apt-get installed ).I am thinking the more reasonable way is to remove 'haproxy deployment codes' away from 'deploy rgw codes', do you think that will be more workable in your environment?

Hi @xuechendi
In my opinion haproxy is useful in case we want to run COSbench over multiple RGW instances to test scalability and performance out of multiple RGW instances.

I guess as a long term solution we need to make haproxy part more flexible with a check like this

if os==ubuntu/debian 
 do this 
else if os==rhel 
 do this 

I am not sure how difficult it is to implement this ? Do you have any alternate thoughts to fix this ?

I didn't go that way is because I don't have a rhel setup myself, but I think to separate the handling by os is the first thing I need to add.

It that ok for you to share a centos haproxy default and rgw deployed configuration to me,so I can just fix this on my Ubuntu setup?

Unfortunately i don't have working haproxy config file for CentOS system , i hope if you have a Ubuntu one then tailoring it for CentOS should not be much change ?
