Error 500 on ZooNavigator and Marathon pages
Error 500 on the Marathon and ZooNavigator pages when ML is installed under the root user.
Description
By default, in this case, the installer fails to add a user for Nginx in nginx.conf, and all slave processes start under the "nobody" user. And the user has problems with access to some files. As a result, you receive error 500.
Solution
To fix the issue, add the following line in nginx.conf:
user root;
After that, restart the Nginx service.
