nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

Today I’m facing the following error message after added custom module to nginx

1	root@ibnuyahya:~# sudo /etc/init.d/nginx restart

2	* Stopping Web Server nginx [OK]

3	* Starting Web Server nginx                                                                                                                                                         nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

4	nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

5	nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

6	nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

7	nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

8	nginx: [emerg] still could not bind()

solution?
check running pid

1	fuser -n tcp 80

2	80/tcp:              26621 26622

Kill

1	root@ibnuyahya:~# kill -9 26621

2	root@ibnuyahya:~# kill -9 26622

restart nginx

view source

print?

1	root@ibnuyahya:~# sudo /etc/init.d/nginx restart
