Plesk 17: Websites not accessible after system reboot

Hosted websites stopped after rebooting a server with Plesk 17.x (I had problems with 17.0 and 17.5 with activated nginx reverse proxy onUbuntu 16.x)

I only could reproduce this problem (so far), if I activate nginx as a reverse proxy for Apache.

What does the cause seem to be?

The nginx service isn’t started after a reboot. It can therefore be assumed that the service must be simply enabled in the host system:

/usr/local/psa/admin/sbin/nginxmng -- disable && /usr/local/psa/admin/sbin/httpdmng --reconfigure-all

I’ve also created a more detailed GIST on GitHub

I hope that helps you too — if yes, just clap a few times ツ
