[Solved] I've updated CentOS 7 and now nginx doesn't start automaticaly on system boot

networking

I've updated my server's OS (CentOS 7) through the command "yum update" and now NGINX doesn't start during system boot.

At startup log shows:

Curiously, I can start NGINX manually after booting, and it works fine.

CentOS 7.4.1708

NGINX 1.12.1

/etc/systemd/system/multi-user.target.wants/nginx.service

[Unit]
Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs/
After=network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

[Service]
Type=forking
PIDFile=/var/run/nginx.pid
ExecStartPre=/usr/sbin/nginx -t -c /etc/nginx/nginx.conf
ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s TERM $MAINPID

[Install]
WantedBy=multi-user.target

I have a server with the same configuration on DigitalOcean and that same problem didn't happen. Can it be a problem with the package, since the repositories are different?

If you try to start a daemon that binds to a network interface that hasn't been started yet, then you get the above error (Cannot assign requested address).

To allow daemons to bind to non-existing network interfaces, and thus avoid this problem, create the file: /etc/sysctl.d/80-network.conf with the following contents:

net.ipv4.ip_nonlocal_bind = 1
net.ipv6.ip_nonlocal_bind = 1

Yep… and it works. Thank you!
