Re: ceph-deploy problems on CentOS-6.4

I don’t think this is true… I am behind a proxy and use ceph-deploy and I do not have to use --no-adjust-repos if I set up all my proxies correctly.

One more thing, because you are using a proxy, you need to include the --no-adjust-repos flag at the end of the install command in Ceph-deploy.

I will be honest. I found with my install that doing the yum install outside of Ceph-deploy on the Ceph node itself works much better. It does require all the packages and dependencies to be available on the node, but it saved me a lot of debugging hassle and time. In fact, I am fast developing the opinion that doing most things outside of Ceph-deploy (certainly on my Red Hat build) is the easier option.

Now you need to set the Curl proxy in /root/.curlrc (might also set it in ~/.curlrc for good measure).

 

To ceph-deploy on CentOS 6.4 I had to set all these proxies:

Curl: /root/.curlrc

rpm: /root/.rpmmacros

wget: /etc/wgetrc

yum: /etc/yum.conf

I made the changes and it seems now it can successfully wget the rpm but getting a different error now:

You also want to make sure that if you are using a proxy your proxy settings are maintained through sudo.  

 

With my deployment I had to add a line to my sudoers file to specify that the https_proxy and http_proxy settings are maintained.  Didn’t work otherwise.

 

Defaults env_keep += "http_proxy https_proxy"

If you are behind a proxy try configuring the wget proxy through /etc/wgetrc.  I had a similar problem where I could complete wget commands manually but they would fail in ceph-deploy until I configured the wget proxy in that manner.

Hi All,

 

I am a newbie to ceph. I am installing ceph (dumpling release) using ceph-deploy (issued from my admin node) on one monitor and two OSD nodes running CentOS 6.4 (64-bit) using followed instructions in the link below:

 

http://ceph.com/docs/master/start/quick-ceph-deploy/

 

My setup looks exactly like the diagram. I followed pre-flight instructions exacty as outlined in the link below:

 

http://ceph.com/docs/master/start/quick-start-preflight/

 

The ceph-deploy takes forever and then throws up the following error:

Interestingly, “wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm” on each nodes (1 mon and 2 OSDs) succeeds without any problem. I have tried everything many times with root user, ceph user etc. but it fails every time! It is very frustrating!

 

Has anyone else experienced the same or similar problem?

 

Thanks a lot in advance!
