Dataiku not starting due to issue with nginx

Gabriel

Hi everyone

When I try to start dss, I get an error associated with nginx. See the following two commands.

$ /home/.../dataiku/dss_data/bin/dss start

Waiting for DSS supervisor to start ...
backend                          STARTING
ipython                          STARTING
nginx                            BACKOFF   Exited too quickly (process log may have details)
DSS started, pid=6238
Waiting for DSS backend to start ....

$ /home/.../dataiku/dss_data/bin/dss status

backend                          RUNNING   pid 6250, uptime 0:00:20
ipython                          RUNNING   pid 6251, uptime 0:00:20
nginx                            FATAL     Exited too quickly (process log may have details)

When I check the logs, I see the following.

$ sudo nano home/.../dataiku/dss_data/run/nginx.log

nginx binary "nginx" not found
nginx binary "nginx" not found
nginx binary "nginx" not found

In my understanding, the path dss uses to initiate the nginx binary is wrong since nginx is running on my server:

$ sudo systemctl status nginx

nginx.service - The Nginx Web Server
   Loaded: loaded (/etc/systemd/system/nginx.service; enabled; vendor preset: disabled)

  Process: 1520 ExecStart=/usr/local/nginx/sbin/nginx (code=exited, status=0/SUCCESS)
  Process: 1473 ExecStartPre=/usr/local/nginx/sbin/nginx -t (code=exited, status=0/SUCCESS)

           ├─1536 nginx: master process /usr/local/nginx/sbin/nginx
           └─1537 nginx: worker process

Am I correct in my assumption and where can I set the path to the nginx binary? I couldn't find the corresponding setting.

Thanks in advance, help is greatly appreciated.

Hello

You should point your nginx to the following path /usr/sbin/nginx

You can do it with symlink command :

sudo ln -s /usr/local/nginx/sbin/nginx /usr/sbin/nginx

Stop current nginx process and restart the application.

I spent several hours on troubleshooting. You made my day!
