I created the “common” folder/directory and proceeded with the installation. The site creation completed, up to the point where NGINX needed to reload, and then it came to a screeching halt, with the following errors/debug info:
2018-10-16 12:27:54,096 (INFO) ee : Reload : nginx
2018-10-16 12:27:54,126 (DEBUG) ee : nginx: [emerg] open() "/etc/nginx/common/acl.conf" failed (2: No such file or directory) in /etc/nginx/common/locations-php7.conf:47
nginx: configuration file /etc/nginx/nginx.conf test failed
2018-10-16 12:27:54,126 (INFO) ee : [Failed]
2018-10-16 12:27:54,126 (INFO) ee : Oops Something went wrong !!
2018-10-16 12:27:54,127 (INFO) ee : Calling cleanup actions ...
…and then the script goes into removal mode; removing the website I just tried to create.
At this point I uninstalled NGINX using:
sudo ee stack purge --nginx
…and then re-installed it using:
sudo ee stack install --nginx
…and finally created a website using:
ee site create
This time, the creation of the website went as it should have.
