Question: Unable to start nginx: Not starting nginx as it is disabled in config


Applicable to:

• Plesk for Linux

Symptoms

• Plesk websites are not accessible.

• The following error can be found in the nginx error log file /var/log/nginx/error.log or on the Home page in Plesk:

• [emerg] 2060#0: duplicate listen options for [203.0.113.2]:80 in /etc/nginx/plesk.conf.d/server.conf:29

• It is not possible to start the Nginx webserver:

# systemctl status nginx
...
Process: 21034 ExecStartPre=/bin/sh -c [ '${NGINX_ENABLED}' = 'yes' ] || { echo Not starting nginx as it is disabled in Plesk. Run 'plesk sbin nginxmng -e' to enable nginx in Plesk.; exit 1; } (code=exited, status=1/FAILURE)


Cause

Nginx is disabled for starting in its own configuration.

In the corresponding configuration file, the NGINX_ENABLED line without any value is present:

• For RHEL-based operating systems: /etc/sysconfig/nginx.
• For Debian-like operating systems: /etc/default/nginx.

Resolution

1.Connect to the server via SSH.

2.Reconfigure nginx and Apache to listen on the correct ports by executing the two commands below:

# plesk sbin nginxmng -d

# plesk sbin nginxmng -e

                              In case LiteSpeed Web Server is used

Warning: LiteSpeed requires nginx to be disabled, as it cannot work with it.

1.Connect to the server via SSH.

2.Disable nginx in Plesk:

# plesk sbin nginxmng -d


Additional information

Nginx service enabled in Plesk is unable to start: Not starting nginx as it is disabled in Plesk.
