nginx如何停止命令

Introduction

Nginx is a popular web server that is fast and highly efficient. However, there may be times when you need to stop or terminate the nginx process. In this article, we will discuss the different ways to stop nginx and shutdown its processes.

Stopping Nginx Gracefully

To gracefully stop nginx, you can use the -s flag followed by the stop command. This command will stop Nginx after it has completed its current requests.

sudo nginx -s stop

This command will send a signal to the nginx master process to stop accepting new connections, while allowing existing connections to complete before terminating.

Stopping Nginx Immediately

To stop nginx immediately, you can use the kill command followed by the process ID of the nginx master process. This command will kill all worker processes and stop nginx immediately.

sudo kill $(cat /var/run/nginx.pid)

This command sends a SIGTERM signal to the nginx master process, which in turn sends a SIGQUIT signal to each worker process to shut down gracefully.

Checking the Status of Nginx

To check the status of Nginx, you can use the systemctl command.

sudo systemctl status nginx

This command will show you the current status of Nginx, whether it is running or stopped. If Nginx is running, you will see a message that says “active (running)”. If Nginx is not running, you will see a message that says “inactive (dead)”.

Conclusion

In this article, we’ve covered the different ways to stop nginx and shutdown its processes. Whether you want to stop it gracefully or immediately, you can use the commands listed above to do so. It is important to note that you should always check the status of Nginx before stopping or restarting it to ensure that you are not disrupting any critical services.
