Nginx: [emerg] bind () to [:]: 80 failed (98: Address already in use) error solution

Install nginx on ubuntu10.04 today. After installation is complete, start nginx and run the following command:

The code is as follows:	Copy code
Sudo/etc/init. d/nginx start

The error message is as follows:

Hankcs @ ubuntu :~ $ Sudo/etc/init. d/nginx start
[Sudo] password for hankcs:
* Starting nginx: [emerg] bind () to [:]: 80 failed (98: Address already in use)
Nginx: [emerg] bind () to [:]: 80 failed (98: Address already in use)
Nginx: [emerg] bind () to [:]: 80 failed (98: Address already in use)
Nginx: [emerg] bind () to [:]: 80 failed (98: Address already in use)
Nginx: [emerg] bind () to [:]: 80 failed (98: Address already in use)
Nginx: [emerg] still cocould not bind ()

Problem Description: The address is already in use. The nginx service may be stuck, causing Port occupation. This error occurs.

Solution:

First, use lsof: 80 to check which program occupies port 80. Lsof returns the following results:

The code is as follows:	Copy code
Hankcs @ ubuntu :~ $ Netstat-ntpl Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name Tcp 0 0 127.0.0.1: 53 0.0.0.0: * LISTEN- Tcp 0 0 127.0.0.1: 631 0.0.0.0: * LISTEN- Hankcs @ ubuntu :~ $ Killall-9 nginx

Nginx: no operation found

Nginx configuration file

The code is as follows:	Copy code
Hankcs @ ubuntu :~ $ Sudo gedit/etc/nginx/sites-available/default Modify this section: Listen 80; Listen [:]: 80 default_server; Is Listen 80; Listen [:]: 80 listen 6only = on default_server;

Start nginx and solve it perfectly!

If you find the operation, we can perform the following operations:

It was found that it was an nginx program, so we dropped the nginx service k and restarted the service .. The command is as follows:

The code is as follows:	Copy code
Kill-9 3274 Kill-9 3547 Service nginx start Starting nginx:

Add an 80 occupation solution

Cause: port 80 is occupied. Run the "lsof-I: 80" command to check which program occupies port 80. My result shows that port 80 is occupied by apache.
