Can't start nginx in step 6 Running Extensible Service Proxy of Quickstart

[bitr...@gmail.com]

I am trying to do the Quickstart here: https://cloud.google.com/endpoints/docs/quickstart-compute-engine

When I get to step 6, and try and restart the nginx, I get the following:

The programs included with the Debian GNU/Linux system are free software;

the exact distribution terms for each program are described in the

individual files in /usr/share/doc/*/copyright.

Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent

permitted by applicable law.

user1@linux:~$ sudo service nginx restart

Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.

user1@linux:~$ systemctl status nginx.service

Failed to get D-Bus connection: No such file or directory

user1@linux:~$ journalctl -xn

No journal files were found.

As you can see I am using the Debian Linux Compute Engine Instance.

Any help appreciated.

I just tried it. It works for me.

It is possible that the service file was not downloaded if two metadata values were not set correctly.

Inside your GCE VM instance, you can check the folder /etc/nginx/endpoints/, it should have a file service.json.  If it is not there,  the service file was not downloaded. Most likely you did not set the two metadata value correctly. You can go to your VM instance in the Console to check the two metadata values.

They are set in the "Creating a Compute Engine instance" section,  the step 4. 

If they are not correct,  you have to delete this instance, and start over again at creating a new VM instance.

Thanks Wayne! That did it. I missed the step where I set the endpoints-service-version. It assumed I would do Add item again, as there is no step d telling me to do so.

Hi,

I am trying the tutorial at https://cloud.google.com/endpoints/docs/openapi/get-started-compute-engine

I am unable to get nginx (Extensible Service Proxy) working. Here's the contents of /var/log/nginx/error.log. I think I have set all the metadata values correctly. (Initially I had not set the config ID / service version, but had to set that to remove one error). 

Now facing this error. Is it due to a missing API key? Because when I paste the url into a browser, it says "The request is missing a valid API key."

Can you please help? Thanks.

cat /var/log/nginx/error.log

ESP is getting access token from GCE metadata server, and pass it to  https://servicemanagement.googleapis.com to fetch the service config.   It failed with 403.

The code is here: https://github.com/cloudendpoints/esp/blob/master/start_esp/fetch_service_config.py#L207

My speculation is:  GCE VM was not created with the same project as the service "echo-api.endpoints.example-serious-unison-203011.cloud.goog"

So it could not access the service config.
