Rails server issue in production environment

Ruby
1

Hi guys,

I’m having troubles to run rails server in production environment.

It’s working fine in development environment.

However if i run it as ‘rails server -e production’,
Static page like public/index.html is fine.
But any controller (maybe it’s DB) involved requests will fail and cause
the server died, can’t stop it by CTRL+C, have to kill the process. The
page loading never end. No error page returned.

I’m assuming it could be some db connection issue.
Because production db is using AWS RDS.
However, both ‘rails c production’ and ‘rails dbconsole production’ can
successfully connect to RDS.

I couldn’t figured out why.

Can you share your production log? Since it dies after the request is
made
the answer should definitely be in that log file.

Unfortunately no errors in server log.

Could you (i.e., the OP) please also share some details about the
environment,
like O/S, softwares in use, etc.?

The problem is assets.
‘rake assets:precompile’ fixed it.

In production ENV the assets (e.g. static assets) are served by the web
server not by rack-servers. So you have to run rake assets:precompile
and configure the web-server to actually serve them.

Thanks guys

It is a bit strange that the log didn’t say anything about the assets
precompile not being done. Usually in the log it would mention that you
are
requred to run assets:precompile. Anyway happy to know that the issue
has
been resolved.
