Nginx

Let Start with Nginx...

Nginx, pronounced like “engine-ex”, is an open-source web server that, since its initial success as a web server, is now also used as a reverse proxy, HTTP cache, and load balancer.

Features of NGINX

Some features of Nginx are as follows:

• Reverse proxy with caching
• IPV6
• Load Balancing
• Web Sockets
• Handling of static files, index files, and auto-indexing
• FastCGI support with caching
• URL rewriting and redirection

Installation in ubuntu

Before the Nginx installation,update the system.

sudo apt update -y

After completing the updating process,install the Nginx

sudo apt-get install nginx

Managing the Nginx Process

Check nginx status

sudo systemctl status nginx

To stop your web server

sudo systemctl stop nginx

To start the web server when it is stopped

sudo systemctl start nginx

To stop and then start the service again

sudo systemctl restart nginx

It will show whether nginx is installed and running

Run localhost in curl for looking response Nginx page

Enable UFW (Uncomplicated Firewall)

Uncomplicated Firewall is a program for managing a netfilter firewall designed to be easy to use.UFW is available by default in all Ubuntu installations after 8.04 LTS.

To enable ufw service,type:

sudo ufw enable

To view which applications have installed a profile

sudo ufw app list

To allow Nginx Full service

sudo ufw allow ‘Nginx Full’

To check ufw status

sudo ufw status

Create a Directory Structure

Set up hacking-capture.com as your domain name, but you should replace it with your own. Nginx on Ubuntu 18.04 has one server block enabled by default that is configured to serve documents out of a directory at /var/www/html.

sudo mkdir /var/www/hacking-capture.com/

set owership of directory with www-data

sudo chown -R www-data:www-data /var/www/hacking-capture.com/

set the permission of directory

sudo chmod -R 755 /var/www/hacking-capture.com/

create a html page in /var/www/hacking-capture.com/index.html

save and exit

Setting up server block

nginx server block

In nginx server configuration block, which is similar to the default, but updated for our new directory and domain name:

sudo nano /etc/nginx/sites-available/hacking-capture.com

server {
        listen 80;
        listen [::]:80;

        root /var/www/hacking-capture.com/;
        index index.html;

        server_name hacking-capture.com www.hacking-capture.com;

        location / {
                try_files $uri $uri/ =404;
        }
}

Enable the server block

Enable the file by creating a link from it to the sites-enabled directory, which Nginx reads from during startup:

sudo ln -s /etc/nginx/sites-available/hacking-capture.com /etc/nginx/sites-enabled/

To avoid a possible hash bucket memory problem that can arise from adding additional server names, it is necessary to adjust a single value in the /etc/nginx/nginx.conf file.

sudo nano /etc/nginx/nginx.conf

Find the server_names_hash_bucket_size directive and remove the # symbol to uncomment the line

...
http {
    ...
    server_names_hash_bucket_size 64;
    ...
}
...

test the nginx syntax error in any nginx files

nginx -t

Then, reload the nginx

sudo systemctl reload nginx
