Nginx Linux: Setup & Configuration Guide

Here are some common Nginx technical guides for Linux systems.

1. Install Nginx: Use a package manager (such as apt or yum) to install Nginx. For example, on Ubuntu, you can use the following command to install: sudo apt-get install nginx.
2. To start and stop Nginx: Use the command “sudo service nginx start” to start Nginx and “sudo service nginx stop” to stop it.
3. Configuration file: The main configuration file for Nginx is located at /etc/nginx/nginx.conf. This file can be used to configure global settings for Nginx, such as the number of worker processes and the location of log files.
4. Virtual host configuration: Nginx allows for configuring multiple virtual hosts, each with their own settings. The configuration files for virtual hosts are typically found in the /etc/nginx/conf.d/ directory.
5. Reverse Proxy: Nginx can act as a reverse proxy server, forwarding requests to the real servers in the backend. Use the proxy_pass directive in virtual host configuration to set up the reverse proxy.
6. Load balancing: Nginx can be configured to distribute requests to multiple backend servers. You can use the upstream directive to define backend servers and the proxy_pass directive to configure load balancing.
7. SSL/TLS support: Nginx can be configured to use SSL/TLS encryption to guarantee secure data transmission. You can use the directives ssl_certificate and ssl_certificate_key to configure SSL/TLS certificates.
8. Caching: Nginx can be configured to improve performance by setting up cache. The proxy_cache_path directive can be used to configure the location and size of the cache.
9. Nginx will generate access logs and error logs. The location and format of the log files can be configured in the configuration file.
10. Safety: Nginx can be configured with various security features such as access restrictions and prevention of DDoS attacks. Access can be limited using the allow and deny directives.

Here is a common Linux system Nginx technical guide. Depending on actual requirements, further understanding and configuring of Nginx may be needed as necessary.
