Foreman Installer giving error while installing in CentOS 7

Support

Problem:
[root@mongos foreman-proxy]# foreman-installer
/Stage[main]/Foreman_proxy::Register/Foreman_smartproxy[mongos.example.com]: Could not evaluate: Proxy mongos.example.com cannot be retrieved: unknown error (response 500)

Expected outcome: Clean 100% installation without any error

hostname :
[root@mongos foreman-debug-gDw0M]# hostname -f
mongos.example.com

I already made the entry in /etc/hosts

Foreman and Proxy versions:

[root@mongos foreman-debug-gDw0M]# rpm -qa | grep foreman

Did you make the entry for localhost, or did you make the entry for the actual IP? Mongo may not be listening on localhost. You can check with “netstat -tupln” and see what IP/port it listens on.

Hey James,

Thanks for your reply.

Could you please tell where should I make an entry for localhost or IP.

I already make an entry in /etc/hosts as IP & mongos.example.com.

Kindly reply.

I think he is asking if there is a 127.0.0.1 entry in your /etc/hosts file.

The netstat would be useful to see if your service is listening on ipv4 or ipv6 vs both.

netstat -tupln

Thank You Jeff…

It’s working now after rebooting my machine.

7

Sounds like that started the mongodb service, which wasn’t running, based on your netstat output.

8

Yes Probably… Thanks for your help & support.

You can close this thread.

Waiting for your reply

a 500 error indicates that there was some issue with the smart proxy, not necessarily the same one as described in this thread - many errors might lead to 500 message. Note that this thread is from over two years ago, so most likely you are seeing a different issue.
I suggest opening a new thread with what foreman versions you are attempting to install, as well as the contents of /var/log/foreman-proxy/proxy.log and /var/log/foreman-installer/installer.log.

Ok,thank you so much
