Part 2: Introduction to Nginx

Nginx is a web server software that is known for its fast performance and ability to handle high traffic websites. It was created by Igor Sysoev in 2002 and has since become one of the most popular web server software options available. Nginx is open source and free to use, and is commonly used in combination with Cent OS web server.

Some of the key features of nginx include its ability to handle multiple connections simultaneously, its scalability, and its ability to act as a reverse proxy. Additionally, nginx is known for its low resource usage, which makes it an excellent choice for websites with high traffic or limited resources.

Part 3: Installing and Configuring Nginx on Cent OS Web Server

Now that we have a better understanding of both Cent OS web server and nginx, let’s take a look at how to install and configure nginx on Cent OS web server.

Step 1: Update Your System

The first step in installing nginx on Cent OS web server is to make sure that your system is up-to-date. You can do this by running the following command:

yum update

This will update your system’s packages to the latest version.

Step 2: Install Nginx

The next step is to install nginx. You can do this by running the following command:

yum install nginx

This will download and install nginx on your system.

Step 3: Start and Enable Nginx

Once nginx is installed, you can start it by running the following command:

systemctl start nginx

You can also enable nginx to automatically start at boot time by running the following command:

systemctl enable nginx

Now that nginx is installed and started, let’s take a look at how to configure it for your website.

Step 4: Configure Nginx for Your Website

The configuration file for nginx is located in the /etc/nginx directory. You can edit this file using a text editor such as vi or nano.

To configure nginx for your website, you will need to create a new configuration file in the /etc/nginx/conf.d directory. This file should be named after your website, with a .conf extension. For example, if your website is example.com, the configuration file should be named example.com.conf.

Open the configuration file in your text editor and add the following code:

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

This code specifies that nginx should listen on port 80 (the default HTTP port), that the server name is example.com, that the root directory for the website is /var/www/example.com, and that the default file to load is index.html.

Save the configuration file and exit your text editor.

Step 5: Test Your Configuration

Before you can use nginx to serve your website, you should test your configuration to make sure there are no errors. You can do this by running the following command:

nginx -t

If there are no errors, you can restart nginx by running the following command:

systemctl restart nginx

Your website should now be accessible at http://example.com.

Part 4: Optimizing Nginx for Performance

Now that nginx is installed and configured for your website, it’s important to optimize it for maximum performance. There are a few key areas you can focus on to improve nginx’s performance:

Optimization 1: Caching

Caching is a technique that can significantly improve website performance by storing frequently requested content in memory or on disk. When a user requests content that is already cached, nginx can serve the content directly from cache without having to retrieve it from the backend server.

To enable caching in nginx, you will need to add the following code to your website’s configuration file:

location / {
    proxy_cache cache_zone;
    proxy_cache_key "$scheme$request_method$host$request_uri";
    proxy_cache_valid 200 1h;
}

This code specifies that nginx should cache content in a cache zone named cache_zone, and that cached content should be valid for 1 hour.

Optimization 2: Compression

Compression is a technique that can reduce the size of content sent over the network, which can significantly improve website performance. Nginx supports gzip compression, which compresses content before sending it to the client.

To enable compression in nginx, you will need to add the following code to your website’s configuration file:

gzip on;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

This code enables gzip compression and specifies which file types should be compressed.

Optimization 3: Load Balancing

If your website receives a lot of traffic, you may want to consider using load balancing to distribute the load across multiple backend servers. Nginx supports load balancing out of the box, and can be configured to distribute traffic based on various algorithms such as round-robin, least connections, and IP hash.

To enable load balancing in nginx, you will need to add the following code to your website’s configuration file:

upstream backend {
    server backend1.example.com;
    server backend2.example.com;
}

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://backend;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

This code specifies that nginx should distribute traffic to two backend servers named backend1.example.com and backend2.example.com.

Optimization 4: SSL/TLS

If your website requires secure connections, you should consider enabling SSL/TLS encryption. Nginx supports SSL/TLS out of the box, and can be configured to use a variety of encryption protocols and ciphers.

To enable SSL/TLS in nginx, you will need to obtain an SSL/TLS certificate and key, and then add the following code to your website’s configuration file:

server {
    listen 443 ssl;
    server_name example.com;

    ssl_certificate /path/to/certificate.crt;
    ssl_certificate_key /path/to/private.key;

    location / {
        proxy_pass http://backend;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

This code specifies that nginx should listen on port 443 (the default HTTPS port), use SSL/TLS encryption, and use the specified SSL/TLS certificate and key.
