Nginx 2019 Beginner To Advanced
What is Nginx?
Nginx (pronounced ‘Engine-X’) is an open source web server and a reverse proxy server for HTTP, SMTP, POP3 and IMAP. It was first developed by Igor Sysoev and later donated to the Nginx Software Foundation in July 2011. Nginx is known to be one of the fastest web servers in the world. It has become the first choice for high-traffic websites due to its scalability, ease of use and stability.
Nginx is Primarily used as a web server, but it can also be used as a proxy server for email (IMAP, POP3, and SMTP) and a reverse proxy and load balancer for HTTP, TCP, and UDP servers. It has a number of advanced features that make it an excellent choice for web hosting on a virtual private server (VPS).
Best Practices for using Nginx
When setting up an Nginx server, there are a few best practices to keep in mind. First, always ensure that the server is secure and your web applications are up to date. Some version of Nginx come with security features such as TLS/SSL, anti-malware, and OWASP secure header to protect your web content and user data. Secondly, always keep your server software up to date with the latest security patches. Finally, configure the server to serve only the content and features that you need. Minimizing the configuration and features will help increase the server’s performance and decrease the risk of security vulnerabilities.
Nginx Configuration For Best Performance
To get the best performance out of your Nginx server, there are a few configuration steps you can take. The most important step is to optimize your server’s memory usage. To do this, you will need to adjust the worker_processes, worker_connections, and keepalive_timeout settings in the nginx.conf file. You will also need to increase the server’s performance by adding the gzip feature to compress the content. Finally, configure the server to serve your static content (e.g., images, HTML pages, etc.) from a separate location or server.
How to Secure Nginx Server?
Securing your Nginx server is a must for any webmaster or administrator. To secure it, you can implement a few measures such as enabling SSL/TLS, configuring the web server to listen on only certain ports and IP addresses, and setting up a password protected directory. You can also configure Nginx to hide your server header and use the ModSecurity module to detect and protect against malicious attacks. Finally, using the latest version of Nginx will help ensure that all security patches are applied and updated.
How to Monitor Nginx Performance?
Monitoring your Nginx server’s performance is an essential part of web development. To do this, you can use tools such as the web server monitoring programs and the Nginx Status page. These tools allow you to view the response times and throughput of your web server, as well as detect any errors or performance issues. You can also use log files to monitor the performance of your server, as well as measure your server’s uptime and total traffic.
How to Troubleshoot Nginx Server?
Troubleshooting your Nginx server can be a time consuming task. To make the process easier, it is important to use a good logging utility such as the Apache mod_log_config module or a third-party log monitoring tool. You can also use the Nginx Status page to troubleshoot any issues with the server. Additionally, using a debugging tool such as the GDB debugger can make the process of troubleshooting much easier.
Conclusion
Nginx is a powerful and versatile open source web server and proxy server that is used by many of the world’s largest websites. For maximum performance and security, it is important to configure your Nginx server correctly. Additionally, it is important to monitor and troubleshoot your server regularly to ensure that it is running smoothly.
