Nginx is open source web and reverse proxy server.In this blog we will learn how to create authentication on Nginx server to access the web site running on nginx server.
I have create a scenario to apply the authentication. lets the domain name of website is www.gnu-org, and its running by Nginx web server. Document root for the site is in /var/www/html/gnu-linux and the configuration of the nginx for the gnu-linux is in /etc/nginx/nginx.conf
Document root is the directory where you keep the website file for the domain,
Now to make authentication to access the site, we will follow these steps.
Step 1. Create the password file
Use apache’s htpasswd to create the password file.If it is not found install it.
# yum install httpd-tools
# htpasswd -c /var/www/html/gnu-linux/.htpasswd user1
It will ask to create a password, type your password.
htpasswd takes two parameter first the location of htpasswd file in documented root and second parameter is the user name.
Step 2. Configure Nginx file
# vim /etc/nginx/nginx.conf
Now in this edit these two lines to the location where you want the authentication.
auth_basic_user_file /var/www/gnu-linux/.htpasswd ;
server_name www.gnu-linux.org ;
auth_basic_user_file /var/www/html/gnu-linux/.htpasswd ;
index index.html index.htm;
save the file and restart your nginx server.
# service nginx restart
Step 3. Open the web browser and type your url.
You will find a authentication window.
So its just very simple to create a Authentication for the Nginx
