The purpose of this article is to tell you what to do when opening Nginx when the port is occupied. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

As shown in the figure:

View port occupancy:

Sudo netstat-apn | grep 80

View the processes that occupy the port:

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

The following describes the start, stop and restart of Nginx

Start

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

For example:

[root@LinuxServer sbin] # / usr/local/nginx/sbin/nginx-c / usr/local/nginx/conf/nginx.conf

Stop it

There are three ways to stop nginx:

Stop calmly

1. Check the process number

[root@LinuxServer ~] # ps-ef | grep nginx

2. Kill the process

[root@LinuxServer ~] # kill-QUIT 2072

Quick stop

1. Check the process number

[root@LinuxServer ~] # ps-ef | grep nginx

2. Kill the process

[root@LinuxServer ~] # kill-TERM 2132 or [root@LinuxServer ~] # kill-INT 2132

Forced stop

[root@LinuxServer] # pkill-9 nginx

Restart

1. Verify that the nginx configuration file is correct

Method 1: enter the nginx installation directory sbin and enter the command. / nginx-t

See the following display of nginx.conf syntax is ok

Nginx.conf test is successful

Indicates that the configuration file is correct!

Method 2: add-t before the startup command-c

2. Restart the Nginx service method 1: 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 the nginx service
