How to solve the problem that the port is occupied when Nginx is opened?

As shown in the figure:

View port occupancy:

sudo netstat -apn | grep 80

To view processes occupying ports:

ps -ef | grep 3345

The result shows that port 80 is occupied by nginx itself, so you can kill the process and restart nginx.

sudo kill -9 3345

sudo netstat -apn | grep 80

After successfully killing the process, start nginx.

Nginx started successfully. Enter the ip address of the system where nginx is located in the browser to verify whether nginx started successfully.

The following describes the start, stop and restart of nginx.

start

Startup code format: nginx installation directory address-Cninx configuration file address

For example:

2. Kill the process

Quick stop

1. Check the process number

2. Kill the process

Forced stop

Method 2: add -t before the start command-c.

2. Method 1 of restarting nginx service: Enter the nginx executable directory sbin and enter the command. /nginx -s reload.

Method 2: Find the current nginx process number, and then enter the command: kill -hup process number to restart nginx service.
