nginx does not start automatically

[AdventureTime]

It started when I updated the repo, then even when I updated the entire server using dnf upgrade -y

What are your thoughts about it?

It works by starting it manually by pressing the green start button.

check the bind

[AdventureTime]

Thanks for replying, even though I do not know what BIND is and how to configure it and even how it works.

What I did is the following:

So you need to tell your linux to allow processes to bind to the non-local address. Just add the following line into /etc/sysctl.conf file:

# allow processes to bind to the non-local address
# (necessary for apache/nginx in Amazon EC2)
net.ipv4.ip_nonlocal_bind = 1
and then reload your sysctl.conf by:

$ sysctl -p /etc/sysctl.conf

which will be fine on reboots.

It is from this site.

After I did that, I can restart the server and nginx will automatically start.

actually if you read the tail -f (the log) you can see that some-domain.tld having error, all you need is remove the dns/zone
or.... maybe just like your case.... BIND

That's weird. I use Cloudflare DNS so I think BIND would be completely bypassed. Right?

^_^ just read the log, then goto dns edit

btw.. that nginx on your server not at CF... right ? even you lock your home then you ask your friend to watch . after that you got fire at some places in side the home.. it's not about your friend... it about your home

[overseer]

nginx is complaining about not being able to bind to the assigned IP address. check that it is correct in the main and vhost config files.
