How to configure load balancing for TCP in Nginx server

PHP code can be executed in many ways: 1. Use the command line to directly enter the "php file name" to execute the script; 2. Put the file into the document root directory and access it through the browser through the web server; 3. Run it in the IDE and use the built-in debugging tool; 4. Use the online PHP sandbox or code execution platform for testing.

Understanding Nginx's configuration file path and initial settings is very important because it is the first step in optimizing and managing a web server. 1) The configuration file path is usually /etc/nginx/nginx.conf. The syntax can be found and tested using the nginx-t command. 2) The initial settings include global settings (such as user, worker_processes) and HTTP settings (such as include, log_format). These settings allow customization and extension according to requirements. Incorrect configuration may lead to performance issues and security vulnerabilities.

Linux system restricts user resources through the ulimit command to prevent excessive use of resources. 1.ulimit is a built-in shell command that can limit the number of file descriptors (-n), memory size (-v), thread count (-u), etc., which are divided into soft limit (current effective value) and hard limit (maximum upper limit). 2. Use the ulimit command directly for temporary modification, such as ulimit-n2048, but it is only valid for the current session. 3. For permanent effect, you need to modify /etc/security/limits.conf and PAM configuration files, and add sessionrequiredpam_limits.so. 4. The systemd service needs to set Lim in the unit file

The steps for starting Nginx configuration are as follows: 1. Create a systemd service file: sudonano/etc/systemd/system/nginx.service, and add relevant configurations. 2. Reload the systemd configuration: sudosystemctldaemon-reload. 3. Enable Nginx to boot up automatically: sudosystemctlenablenginx. Through these steps, Nginx will automatically run when the system is started, ensuring the reliability and user experience of the website or application.

When configuring Nginx on Debian system, the following are some practical tips: The basic structure of the configuration file global settings: Define behavioral parameters that affect the entire Nginx service, such as the number of worker threads and the permissions of running users. Event handling part: Deciding how Nginx deals with network connections is a key configuration for improving performance. HTTP service part: contains a large number of settings related to HTTP service, and can embed multiple servers and location blocks. Core configuration options worker_connections: Define the maximum number of connections that each worker thread can handle, usually set to 1024. multi_accept: Activate the multi-connection reception mode and enhance the ability of concurrent processing. s

Through Docker containerization technology, PHP developers can use PhpStorm to improve development efficiency and environmental consistency. The specific steps include: 1. Create a Dockerfile to define the PHP environment; 2. Configure the Docker connection in PhpStorm; 3. Create a DockerCompose file to define the service; 4. Configure the remote PHP interpreter. The advantages are strong environmental consistency, and the disadvantages include long startup time and complex debugging.
