Systemd

Nginx, OCSP stapling, booting, systemd and Debian 9

Noticed these lines in journalctl when nginx didn’t start after a reboot: Dec 10 17:43:30 mail1 nginx[3485]: nginx: [warn] "ssl_stapling" ignored, host not found in OCSP responder "ocsp.int-x3.letsencrypt.org" in the certificate "/etc/letsencrypt/live/www.example.com/fullchain.pem" Dec 10 17:43:30 mail1 nginx[3485]: nginx: [emerg] bind() to [<IPv6 address>]:80 failed (99: Cannot assign requested address) Dec 10 17:43:30 mail1 nginx[3485]: nginx: configuration file /etc/nginx/nginx.conf test failed Dec 10 17:43:30 mail1 systemd[1]: nginx.service: Control process exited, code=exited status=1 Dec 10 17:43:30 mail1 systemd[1]: nginx.

Boot issue with systemd and NGINX

I ran into a problem with NGINX failing to start on boot/reboot on my Debian 8 (Jessie) server. After reviewing what seemed like a hundred sites to try to find a fix, I stumbled across one solution that worked, but was incredibly inelegant. This was to add: RestartSec=30s Restart=on-failure to nginx.service in the [Service] section using the override.conf. It worked but didn't fix the underlying problem. A quick look using `journalctl -u nginx` showed that the service was failing because the IPv6 address hadn't been assigned to the network adaptor yet.
