Plesk Nginx fail to start on boot
On a Debian Server with Plesk Control Panel, Nginx did not start on boot.
On checking status, i get
root@server:~# systemctl status nginx * nginx.service - Startup script for nginx service Loaded: loaded (/lib/systemd/system/nginx.service; enabled) Active: failed (Result: exit-code) since Mon 2018-01-22 18:30:19 CET; 2min 21s ago Process: 700 ExecStartPre=/usr/sbin/nginx -t (code=exited, status=1/FAILURE) Process: 646 ExecStartPre=/usr/bin/test $NGINX_ENABLED = yes (code=exited, status=0/SUCCESS) Jan 22 18:30:19 server.hostonnet.com nginx[700]: nginx: the configuration file /etc/nginx/nginx.conf syntax is ok Jan 22 18:30:19 server.hostonnet.com nginx[700]: nginx: [emerg] bind() to 82.211.1.93:80 failed (99: Cannot assign requested address) Jan 22 18:30:19 server.hostonnet.com nginx[700]: nginx: configuration file /etc/nginx/nginx.conf test failed Jan 22 18:30:19 server.hostonnet.com systemd[1]: nginx.service: control process exited, code=exited status=1 Jan 22 18:30:19 server.hostonnet.com systemd[1]: Failed to start Startup script for nginx service.

Solution
Edit nginx.service file
vi /etc/systemd/system/multi-user.target.wants/nginx.service
Find line
ExecStartPre
Add above (on a new line)
ExecStartPre=/bin/sleep 60
Find
After=network.target remote-fs.target nss-lookup.target
Replace with
After=network-online.target remote-fs.target nss-lookup.target
Reload service file
systemctl daemon-reload
Here is my modified nginx.service file
