    ## Introduction

    [Nginx]( is the popular web server in the world and it is the backbone for hosting most significant sites on the web. It is used as a reverse proxy and it is user-friendly then Apache.

    In this guide, we will discuss how to Install Nginx on Ubuntu 18.04 server.

    ## Prerequisites

    Before installing Nginx, you should have access to an Ubuntu 18.04 server and created a non-root user account with sudo privileges by following our guide, [Initial server setup with Ubuntu 18.04](

    ## Installing Nginx

    Nginx is available in Ubuntu’s repositories, so you have to install it from these repositories using apt packages.

    First of all, you have to update the local packages index so that you have an access to most recent package listings and then you can install Nginx.
    $ sudo apt update
    $ sudo apt install nginx
    Now apt will install Nginx and required dependencies to your server.

    ## Adjusting the Firewall

    If you want to test Nginx, the first step is the firewall software needs to be adjusted to allow access to the service. If you install Nginx, it registers itself as a service with ufw installation to allow Nginx access.

    We can show the application programmes that ufw knows by using below command.
    $ sudo ufw app list
    Then you will get the following list.


    As above output, there are three profiles available for Nginx:

    ## Nginx Full
    This port opens both port 80 and port 443
    ## Nginx HTTP
    This port opens only port 80
    ## Nginx HTTPS
    This profile opens only port 443

    You can configure SSL for your server by entering the below command.
    $ sudo ufw allow ‘Nginx HTTP’
    You can check the status by entering the below command.
    $ sudo ufw status
    You can see HTTP traffic allowed in the following output.


    ## Checking Web Server
    After installation, Ubuntu 18.04 starts Nginx. The web server starts and running. You can check whether the system is running or not by entering the below command.

    $ systemctl status nginx
    First of all, to test Nginx you have to request a page from Nginx. Then you can see the default Nginx landing page to confirm the software is working correctly through navigating to your server’s IP address. You can get an IP address in several ways. Use the following command to know the IP address.
    $ ip addr show eth0 | grep inet | awk ‘{ print $2; }’ | sed ‘s//.*$//’
    Now you can check it in your browser’s address bar.

    Another way to check this, by entering the below command.
    $ curl -4
    If you have server’s IP address then enter it in your browser’s address bar.

    Then you can see Nginx landing page:


    Then your server is running correctly.

    ## Managing the Nginx Process

    Now you are having a web server up and it is running.

    Use the below command, to stop web server:
    $ sudo systemctl stop nginx
    Use the following command to start web server:
    $ sudo systemctl start nginx
    Enter the below command to restart:
    $ sudo systemctl restart nginx
    To reload the web server, enter the below command.
    $ sudo systemctl reload nginx
    If you want to disable the Nginx, enter the following command.
    $ sudo systemctl disable nginx
    If you want to re-enable Nginx, use the below command.
    $ sudo systemctl enable nginx
    ## Conclusion

    So far we have discussed how to install Nginx.
