Applicable to:

• Plesk Onyx for Linux

Symptoms

• The following error occurs on attempt to start nginx service:

# service nginx start
(98) Address already in use: make_sock: could not bind to address [::]:80

• Apache is listening service listen on 80 port:

# netstat -tulpn | grep :80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 7424/httpd

Note: in case IP address is used by nginx, just kill the hung nginx process

• Apache is configured to listen on port 80 in /etc/httpd/conf/httpd.conf file:

# grep Listen /etc/httpd/conf/httpd.conf

1.Log into the server via SSH

2.Use any text editor to correct aforementioned directive in the Apache configuration files:

Before:

# grep -R Listen /etc/httpd/
/var/httpd/conf/httpd.conf:Listen 0.0.0.0:80

After:

# grep -R Listen /etc/httpd/
/var/httpd/conf/httpd.conf: Listen 0.0.0.0:7080

3.Restart Apache service:

# service httpd restart

4.Regenerate web configuration:

# plesk repair web -y

5.Start nginx service:

# service nginx start
