Install Nginx 10.14 Ubuntu
What is Nginx?
Nginx is a popular open-source web server software created by Igor Sysoev in 2002 which is used to serve web pages, and as a reverse proxy, load balancer, mail proxy and HTTP cache. Nginx primarily works as a web server but due to its popularity, many web hosting companies have started offering it as part of their packages. It is free and can be used for both commercial and non-commercial purposes.
What are the advantages of Nginx?
Nginx offers several advantages when compared to traditional web servers like Apache. It is much faster than Apache and provides better performance. It also has fewer configuration options, meaning there is less up front and ongoing maintenance required. Its low overhead also makes it ideal for resource-intensive applications. Nginx is one of the most secure web servers on the market, making it ideal for hosting secure websites.
Installing Nginx on Ubuntu
Nginx can be quickly and easily installed on Ubuntu using apt-get, the package manager for Ubuntu. To get started, open a terminal window and update apt-get:
sudo apt-get update
Next, install the Nginx package:
sudo apt-get install nginx
Nginx is now installed and running. It should be listening on port 80 (default web port). To test to make sure it is working, you can try visiting http://localhost in a web browser. You should see the default Nginx page.
Confgiuring Nginx is fairly simple. The configuration files are located in /etc/nginx/. By default, there should be a file called nginx.conf. This is the main configuration file. It is important to note that any changes you make to the configuration will require a restart of Nginx to take effect.
The configuration file contains instructions on how Nginx should handle requests. For example, you can change the port on which Nginx listens, the document root (where web files are stored) and enable or disable server modules. For more information on configuring Nginx, please consult the official documentation. The most common configuration options can be found in the nginx.conf file.
Starting and Stopping Nginx
Nginx needs to be started and stopped in order to take any changes to the configuration into effect. To start Nginx, run the following command:
sudo systemctl start nginx
To stop it, run the following command:
sudo systemctl stop nginx
If you are running Nginx as an init script, you can use the service command instead of systemctl.
By default, Nginx is reasonably secure. It runs as an unprivileged user and is disabled from serving any content outside of its root directory. However, there are some simple steps you can take to make your server even more secure.
The first and most important step is to make sure all necessary components, scripts and configuration files are up to date. Most Linux distributions have package management systems like apt-get or yum which can be used to install and manage updates. It is also important to use secure file and directory permissions. Only allow read and execute permissions on files and directories that must be accessible, and use strict access control lists to limit access to sensitive or confidential files.
You should also enable additional security measures, such as IP whitelisting or rate limiting. These options can be enabled in the configuration files. To ensure maximum security, it is also important to keep the web application itself secure. This includes making sure user input is validated and secure coding best practices are followed.
Nginx is a powerful and secure web server, and it is easy to install and configure on Ubuntu. With a few simple steps, you can have your server up and running in no time. To further enhance the security of your server, make sure you keep the web application secure and use additional measures such as IP whitelisting and rate limiting.
