Systemd not starting Nginx properly on Debian 9

jangboing · 04-08-2019, 01:31 PM

Hello,

I'm having some trouble with Systemd and I was wondering if I could get some advice.

I have Nginx set to bind to an IP address. The problem with this configuration is that it doesn't start automatically on boot, but can be started manually afterward. I believe the issue is that Systemd is trying to start Nginx too early, and network configuration hasn't finished.

I've created an override unit file for Nginx that specifies "After=network-online.target" and "Wants=network-online.target", but that doesn't seem to help.

Does anyone have any idea about what might be going wrong? Just to make sure that I don't have something else that's causing the issue, I started another Debian 9 VPS to try it but I run into the same problem.

Thanks.

It would be great if you posted a few more details, such as error messages.

I had a look at Syslog and this is what it says:

Code:

Apr  8 18:07:49 localhost nginx[681]: nginx: [emerg] bind() to [RemovedIPV6]:80 failed (99: Cannot assign requested address)
Apr  8 18:07:49 localhost nginx[681]: nginx: configuration file /etc/nginx/nginx.conf test failed
Apr  8 18:07:49 localhost systemd[1]: nginx.service: Control process exited, code=exited status=1
Apr  8 18:07:49 localhost systemd[1]: Failed to start A high performance web server and a reverse proxy server.
Apr  8 18:07:49 localhost systemd[1]: nginx.service: Unit entered failed state.
Apr  8 18:07:49 localhost systemd[1]: nginx.service: Failed with result 'exit-code'.

Just to confirm that binding to IPv6 is the issue, I removed that part from the configuration file and it worked perfectly. It looks like the IPv6 address isn't available even when Systemd reaches the "Network is Online" target.

I guess I could roll without IPv6 but I'm still curious about why it isn't available during boot.

Thanks for responding.

iirc, there's an additional service called "network-wait-online", which needs to be activated, and then you need to make nginx depend on that.

There is something wrong with your config. Post your config file
