Nginx enable site command

Solution 1:

If you have installed the nginx package from the Ubuntu repositories, you will have two directories.

/etc/nginx/sites-enabled and /etc/nginx/sites-available.

In the main nginx configuration, /etc/nginx/nginx.conf, you have the following line:

include /etc/nginx/sites-enabled/*.conf;

So basically to list all available virtualhosts, you can run the following command:

ls /etc/nginx/sites-available

To activate one of them, run the following command:

ln -s /etc/nginx/sites-available/www.example.org.conf /etc/nginx/sites-enabled/

The scripts that comes with Apache is basically just simple shell wrappers that does something similar as above.

After linking the files, remember to run sudo service nginx reload/ service nginx reload

Solution 2:

Just create this script /usr/bin/nginx_modsite and make it executable.

#!/bin/bash

##
#  File:
#    nginx_modsite
#  Description:
#    Provides a basic script to automate enabling and disabling websites found
#    in the default configuration directories:
#      /etc/nginx/sites-available and /etc/nginx/sites-enabled
#    For easy access to this script, copy it into the directory:
#      /usr/local/sbin
#    Run this script without any arguments or with -h or --help to see a basic
#    help dialog displaying all options.

How it works:

To list all the sites

$ sudo nginx_modsite -l

To enable site "test_website"

$ sudo nginx_modsite -e test_website

To disable site "test_website"

$ sudo nginx_modsite -d test_website

Solution 3:

Are you referring to nginx_ensite and nginx_dissite?

Solution 4:

NGINX

If you're using one of the official upstream packages of nginx from http://nginx.org/packages/, the best way is to navigate to the /etc/nginx/conf.d directory, and rename the affected file from having a .conf suffix to having a different one to disable the site:

sudo mv -i /etc/nginx/conf.d/default.conf{,.off}

Or the opposite to enable it:

sudo mv -i /etc/nginx/conf.d/example.com.conf{.disabled,}

This is because the default /etc/nginx/nginx.conf has the following include directive:

http {
    …
    include /etc/nginx/conf.d/*.conf;
}

---

Debian/Ubuntu

However, if you're using a Debian/Ubuntu derivative, then in addition to conf.d, you may also have the evil non-standard sites-available and sites-enabled directories, some files under which may be sloppily included without regard to their extension:

http {
    …
    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

As such, in Debian/Ubuntu, you might first have to figure out where the site config is located.

• You could use the following command to get a list of all available sites by running find(1) to find all regular files matching the given mask:

  find /etc/nginx -maxdepth 2 -type f \( -path "*/conf.d/*.conf" -or -path "*/sites-*/*" \)

• You could use the following command to get a list of all enabled sites:

  find /etc/nginx -maxdepth 2 \( -path "*/conf.d/*.conf" -or -path "*/sites-enabled/*" \)

Then to disable/enable sites on Debian/Ubuntu:

• To disable a site: if the config is in conf.d, just rename the file to no longer have a .conf suffix; or if in sites-enabled, move it out of sites-enabled.

• To enable a site, the best way would be to move it to /etc/nginx/conf.d, and rename to have a .conf suffix.

P.S. Why do I think Debian's include /etc/nginx/sites-enabled/*; is evil? Try editing a couple of files in that directory, and have your emacs create the backup files (with the ~ suffix), then ask me again.
