ChefServer – Server returned error 502

I’m facing a problem during the Chef server configuration. When I install Chef server for the first time, everything goes well. Now, since I need to do some tests, when I uninstall Chef server and I try to install it again and add a new user, this happens:

ERROR: Server returned error 502 for https://127.0.0.1/users/, retrying 1/5 in 4s
ERROR: Server returned error 502 for https://127.0.0.1/users/, retrying 2/5 in 5s

    from /opt/opscode/embedded/service/omnibus-ctl/chef-server-ctl:192:in `<main>'

Probably is also worth to mention, that when I remove Chef server, I do:

chef-server-ctl uninstall
rm -rf /etc/chef
rm -rf /etc/opscode
rm -rf /opt/opscode
rpm -e chef-server-core-12.2.0-1.el5

I’m using SLES 11 SP1

Any help is appreciated.

Answer

I found how to uninstall Chef completely and also be able to install it successfully:

chef-server-ctl uninstall
rpm -qa | grep chef
rpm -e chef-server-12.2.1-pipapo
rm -rf /root/.chef
rm -rf /etc/opscode
rm -rf /opt/opscode
rm -rf /var/opt/opscode
rcapache2 restart

At this point if you want to add a user or do a chef-server-ctl test you might receive an error like:

ERROR: Errno::ECONNRESET: Connection reset by peer - SSL_connect

To fix this, restart apache2 again and retry.

I hope it helps you!
