nginx/httpd problem (98)Address already in use, bind to :80/443 failed

[brack]

Hello,

I get errors in nginx and httpd.

I used "fuser -k 80/tcp",
nginx worked, my web site is running but it keeps giving errors in the background.

How can i solve this?

Apa he needs to listen on 8181, not 80

Make sure your vhosts aren't trying to bind to 80

[rcschaff]

systemctl stop nginx
Systemctl stop httpd
Killall httpd
Killall nginx
Systemctl start nginx
Systemctl start httpd

Post any errors

I checked and i couldn't find port 80.

systemctl stop nginx
Systemctl stop httpd
Killall httpd
Killall nginx
Systemctl start nginx
Systemctl start httpd

Post any errors

No change.
Nginx and httpd are already running.
When I write "nginx" or "httpd" in terminal, it gives errors. But as i said, nginx is also working.
What else could be a reason?

seems some other httpd version installed do this :
yum remove httpd* cwp-httpd -y
yum install cwp-httpd -y

after that rebuild webserver config.

I did "Save & Rebuild Configuration" from Select Webservers.

and I checked with "yum list httpd" but showing "v2.4.6" again.

seems some other httpd version installed do this :
yum remove httpd* cwp-httpd -y
yum install cwp-httpd -y

after that rebuild webserver config.

"httpd" command doesn't work anymore.

"nginx" problem continues.

It also works.

if the service is already running, and you try to start it again, of course you are going to get bind errors.   try "nginx -s reload" if you want to reload config files, other than that, leave it alone.

Your only issue is apache failing to start due to trying to bind to port 80 as well.  That should have been resolved.  If your saying the systemctl doesn't list an httpd service:

nano /usr/lib/systemd/system/httpd.service

I thought there was a problem. Thank you.

My PHP problems are still not resolved. I can't install in any way.
Do you have any idea about this?

This solved the problem. My httpd.service was different, I don't know why. Thank you.
