Install and Configure Nginx on Ubuntu Linux 18.04 LTS

To install and configure Nginx on Ubuntu Linux 18.04 LTS, follow these steps:

1. Install Nginx using the package manager:

sudo apt update
sudo apt install nginx

2. After the installation is complete, start the Nginx service:

sudo systemctl start nginx

3. To configure Nginx, you will need to edit the configuration files in the /etc/nginx directory. The main configuration file is nginx.conf, which controls the global settings for Nginx.

4. Within the /etc/nginx directory, there is also a sites-available directory that contains configuration files for individual websites. To enable a website, you will need to create a configuration file in this directory and then create a symbolic link to it in the sites-enabled directory.

For example, to enable a website with the domain name example.com, you would create a configuration file called example.com in the sites-available directory and then run the following command:

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

5. The configuration files for Nginx use a specific syntax. Here is an example of a basic configuration file for a website:

server {
    listen 80;
    server_name example.com;
    root /var/www/example.com;

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

This configuration file tells Nginx to listen on port 80, to use the domain name example.com, and to serve files from the /var/www/example.com directory.

6. After you have created and enabled your website's configuration file, you will need to restart Nginx to apply the changes:

sudo systemctl restart nginx
