Install Nginx Ubuntu Server 16.04
Introduction to Nginx
Nginx is a high performance web server and reverse proxy. It is normally used for serving static content such as images, static files, and even video and audio streams. It is also capable of supporting a large variety of web applications and framework, such as PHP, Ruby on Rails, as well as Django. Nginx is widely used in large-scale web applications and is becoming increasingly popular due to its stability, scalability, and performance.
Before embarking on your Nginx installation, there are several prerequisites that need to be accomplished. The first is that the latest version of Ubuntu Server 16.04 should be installed and running. Additionally, it is highly recommended to set a static IP address for the server. This can be accomplished by logging into the server, and then editing the /etc/network/interfaces file. Finally, it is essential that the server is updated and all required packages are installed. This can be done by running the following commands from the command line.
sudo apt-get update
sudo apt-get upgrade
apt-get install build-essential libpcre3 libpcre3-dev libssl-dev
Once all the pre-requisites have been met, you can now start the installation process for Nginx. The first step is to install the Nginx dependencies. This can be done by running the following command from the command line.
sudo apt-get install nginx
Once all the dependencies have been installed, you can now proceed to the actual installation. You can do this by running the below command from the command line.
sudo dpkg -i nginx_* and followed bysudo apt-get -f install
The above command will install the Nginx web server. Once the installation is finished, it is recommended to open the default Nginx configuration file and make any necessary adjustments according to your requirements. To open the Nginx configuration file, you can use the nano text editor, which is the command line editor, by running the following command.
sudo nano /etc/nginx/nginx.conf
Configuration of Nginx
Once you have opened the Nginx configuration file, you can begin editing the settings. This can be done by simply changing the values of the different options to suit your needs. As an example, the following options are important and should be changed depending on the requirements of your web application.
- user www-data;
- listen 80;
- server_name example.com;
- root /var/www/html;
Once the values have been set to your desired values, it is important to save the configuration file. This can be done by pressing ‘Ctrl + X’ followed by ‘Y’ and then ‘Enter’.
Testing the Installation
Once your Nginx configuration is complete, it is now time to test your installation. This can be done by running the following command from the command line.
sudo nginx -t
The above command will check if the Nginx configuration file is valid or not, and if everything is correct, it will output the following message.
test is successful
Once the testing has been successful, you can now start the Nginx web server. This can be done by running the following command.
sudo systemctl start nginx
