New Version Nginx Stable Centos 7

Introduction to Nginx

Nginx is an open-source, high-performance web server and reverse proxy with a strong focus on scalability, security, and performance. It is an extremely versatile and powerful web server that can handle the most complex applications and workloads. It is also an extremely fast web server, capable of serving thousands of requests per second. In addition to being a web server, it is also a reverse proxy server, allowing for incoming requests to be sent to different web applications, or even different servers.

CentOS 7 is an enterprise-level Linux distribution that is designed for long-term stability. It offers a wide range of applications and is a popular choice of operating system amongst web hosting and cloud providers. The latest version, CentOS 7, comes with the latest version of Nginx, and it is becoming increasingly popular as an alternative to Apache, one of the most popular web servers in the world.

Installing Nginx on a CentOS 7 Server

Installing Nginx on CentOS 7 is a fairly simple process. The first step is to download and install the Nginx package. This can be done by using the yum package manager. Simply run the following command as root:

yum install nginx

Once the installation is complete, the Nginx service will need to be started. This can be done with the following command:

systemctl start nginx

Once Nginx is running, it can be configured to listen for incoming requests on a specific port, and to serve them from a specific directory. This can be done by editing the Nginx configuration file. This file is usually located in the “/etc/nginx/nginx.conf” directory. Once the configuration file has been edited, the Nginx service will need to be restarted.

Tuning Nginx

Tuning Nginx on CentOS 7 is an important step in ensuring that the web server is performing at its best. This includes setting the worker connections, processes, and threads, as well as ensuring that limits are in place so that the web server is not overloaded. The following settings can be used to tune Nginx to match the needs of the application being served:

• worker_processes – This option is used to set the number of worker processes that will be used by Nginx.
• worker_connections – This option is used to set the maximum number of connections that can be handled by each worker process.
• client_max_body_size – This option is used to limit the size of uploaded files. It is important to note that it is best to set this option to a lower value than the maximum size that can be uploaded to the server.
• limit_conn_zone – This option is used to set limits on the number of connections that can be established from a single IP address. This is important to prevent DDoS attacks.

These settings are only a small subset of the settings that can be configured in Nginx. As such, it is important to read through and understand the Nginx configuration documentation to ensure that the web server is tuned for peak performance.

Nginx Security

The security of a web server is of paramount importance, and this is especially true when it comes to Nginx. Nginx is designed to be secure by default, but there are some important settings that should be configured to ensure maximum security. The following settings should be used to ensure that Nginx is secured properly:

• disable_symlinks – This setting should be used to disable the ability for Nginx to follow symbolic links.
• server_tokens – This setting should be used to prevent Nginx from disclosing server information.
• add_header – This setting can be used to add response headers that can be used to further secure the server.
• X-Frame-Options – This header should be used to prevent clickjacking attacks.
• X-XSS-Protection – This header should be used to prevent cross-site scripting (XSS) attacks.

In addition to the above settings, it is also important to ensure that all software packages and security patches are kept up to date. This can be done by using the yum package manager.

Nginx Performance Tuning

Nginx can be tuned for better performance by tweaking different settings. These settings include the keepalive timeout, the number of worker connections, the Gzip compression level, the TLS session cache size, and the request header size limit. These settings can be configured in the Nginx configuration file. It is important to note that these settings should be tuned based on the needs of the application being served by the web server.

In addition to the above settings, it is also possible to tune the Nginx server for caching. This can be done by setting the cache_zone, cache_key, and cache_max_size directives. This will allow for the server to cache static content, resulting in improved performance.

Conclusion

Nginx is a powerful web server and reverse proxy with a strong focus on scalability, security, and performance. Installing and configuring Nginx on CentOS 7 is a fairly simple process, and tuning the server for optimal performance can be done by tweaking different settings. Additionally, there are several security settings that should be configured to ensure that the server is secure. With the right configurations, Nginx can be a very powerful and reliable web server for any application.
