Auto Reload NGINX

NGINX Virtual Host

[mitesh@Matrix ~]$  cat /etc/nginx/nginx.conf
##
# Virtual Host Configs
##

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

• As you noticed all the Virtual Host Configuration is stored at /etc/nginx/sites-enabled/location.
• The /etc/nginx/sites-enabled/ location contains only symbolic link of/etc/nginx/sites-available/.

For Example:

[mitesh@Matrix ~]$ ls -l /etc/nginx/sites-available/example.com
-rw-r--r-- 1 root root 418 Jun 23 18:14 /etc/nginx/sites-available/example.com
[mitesh@Matrix ~]$ ls -l /etc/nginx/sites-enabled/example.com
lrwxrwxrwx 1 root root 38 Jun 23 18:14 /etc/nginx/sites-enabled/example.com -> /etc/nginx/sites-available/example.com
