[emerg] 5048#0: bind() to x.x.x.x:80 failed (98: Address already in use)

IT_man

當啟動nginx時, service nginx start (restart) 出現連續5個相同錯誤:
* x7 w' Z# {0 v! a+ Z[emerg] 5048#0: bind() to x.x.x.x:80 failed (98: Address already in use)
6 M9 A0 a3 V  N; l最後再給你出現
. B# ]0 \: f) \$ s' I[emerg] 5048#0: still could not bind()
重開機也沒用
這個意謂"nginx或其他程序正在使用 port 80" , 可以指令 netstat -pan | grep ":80" 或
fuser 80/tcp  (fuser 指令可以參考 http://nixgeek.com/finding-out-what-process-is-listening-on-a-port-under-linux.html)
查看是誰占用 port 80,但nginx也沒占用(啟動不了當然不會占用)


最後  fuser -k 80/tcp  刪除占用 port 80 的的所有程序(process)
* F. w  N3 h% X6 [然後 service nginx restart  ======> OK
