HomeOperation and MaintenanceNginxHow to check whether nginx is started in Linux system

First method: View the process list and filter

Every Linux application will generate a process, then we can judge whether the Nginx process is started by checking whether it exists.

Use ps -ef to list the process, and then filter it through grep.

For example: ps -ef | grep nginx You can see whether the Nginx process exists.

Second method: Check the process id directly

ps -C nginx -o pid

This method of directly returning the pid is more suitable for use in conjunction with other programs, such as Execute this command in the shell/python script to get the pid, and then use the pid to determine whether Nginx is started.

It is recommended to use this method.

Third method: Use the netstat command

If our Nginx is running on port 80, then we can use the netstat -anp | grep :80 command to determine whether Nginx is started.

What versions of Linux are there?

Linux versions include: Deepin, UbuntuKylin, Manjaro, LinuxMint, Ubuntu and other versions. Among them, Deepin is one of the best-developed Linux distributions in China; Ubuntu Kylin is a derivative distribution based on Ubuntu; Manjaro is a Linux distribution based on Arch; LinuxMint's default Cinnamon desktop is similar to Windows XP and is simple and easy to use; Ubuntu is a desktop application Mainly Linux operating system.

NGINX Unit: Key Features and CapabilitiesNGINX Unit: Key Features and CapabilitiesApr 25, 2025 am 12:17 AM

NGINXUnit is an open source application server that supports multiple programming languages ​​and provides functions such as dynamic configuration, zero downtime updates and built-in load balancing. 1. Dynamic configuration: You can modify the configuration without restarting. 2. Multilingual support: compatible with Python, Go, Java, PHP, etc. 3. Zero downtime update: Supports application updates that do not interrupt services. 4. Built-in load balancing: Requests can be distributed to multiple application instances.

NGINX Unit vs. Other Application ServersNGINX Unit vs. Other Application ServersApr 24, 2025 am 12:14 AM

NGINXUnit is better than ApacheTomcat, Gunicorn and Node.js built-in HTTP servers, suitable for multilingual projects and dynamic configuration requirements. 1) Supports multiple programming languages, 2) Provides dynamic configuration reloading, 3) Built-in load balancing function, suitable for projects that require high scalability and reliability.

NGINX Unit: The Architecture and How It WorksNGINX Unit: The Architecture and How It WorksApr 23, 2025 am 12:18 AM

NGINXUnit improves application performance and manageability with its modular architecture and dynamic reconfiguration capabilities. 1) Modular design includes master processes, routers and application processes, supporting efficient management and expansion. 2) Dynamic reconfiguration allows seamless update of configuration at runtime, suitable for CI/CD environments. 3) Multilingual support is implemented through dynamic loading of language runtime, improving development flexibility. 4) High performance is achieved through event-driven models and asynchronous I/O, and remains efficient even under high concurrency. 5) Security is improved by isolating application processes and reducing the mutual influence between applications.

NGINXUnit can be used to deploy and manage applications in multiple languages. 1) Install NGINXUnit. 2) Configure it to run different types of applications such as Python and PHP. 3) Use its dynamic configuration function for application management. Through these steps, you can efficiently deploy and manage applications and improve project efficiency.

NGINX vs. Apache: A Comparative Analysis of Web ServersNGINX vs. Apache: A Comparative Analysis of Web ServersApr 21, 2025 am 12:08 AM

NGINX is more suitable for handling high concurrent connections, while Apache is more suitable for scenarios where complex configurations and module extensions are required. 1.NGINX is known for its high performance and low resource consumption, and is suitable for high concurrency. 2.Apache is known for its stability and rich module extensions, which are suitable for complex configuration needs.

NGINX Unit's Advantages: Flexibility and PerformanceNGINX Unit's Advantages: Flexibility and PerformanceApr 20, 2025 am 12:07 AM

NGINXUnit improves application flexibility and performance with its dynamic configuration and high-performance architecture. 1. Dynamic configuration allows the application configuration to be adjusted without restarting the server. 2. High performance is reflected in event-driven and non-blocking architectures and multi-process models, and can efficiently handle concurrent connections and utilize multi-core CPUs.

NGINX vs. Apache: Performance, Scalability, and EfficiencyNGINX vs. Apache: Performance, Scalability, and EfficiencyApr 19, 2025 am 12:05 AM

NGINX and Apache are both powerful web servers, each with unique advantages and disadvantages in terms of performance, scalability and efficiency. 1) NGINX performs well when handling static content and reverse proxying, suitable for high concurrency scenarios. 2) Apache performs better when processing dynamic content and is suitable for projects that require rich module support. The selection of a server should be decided based on project requirements and scenarios.

The Ultimate Showdown: NGINX vs. ApacheThe Ultimate Showdown: NGINX vs. ApacheApr 18, 2025 am 12:02 AM

NGINX is suitable for handling high concurrent requests, while Apache is suitable for scenarios where complex configurations and functional extensions are required. 1.NGINX adopts an event-driven, non-blocking architecture, and is suitable for high concurrency environments. 2. Apache adopts process or thread model to provide a rich module ecosystem that is suitable for complex configuration needs.
