[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:
[emerg] 5048#0: bind() to x.x.x.x:80 failed (98: Address already in use)
; p2 K0 k# e* R, |5 z7 x. N! Y最後再給你出現
[emerg] 5048#0: still could not bind()
2 T$ {$ ^2 {! E- J. \* w1 ]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)
$ v1 O9 M" y" V查看是誰占用 port 80,但nginx也沒占用(啟動不了當然不會占用)

) A9 M( m- L2 c5 z
5 |; T# s- F$ }最後  fuser -k 80/tcp  刪除占用 port 80 的的所有程序(process)
/ e( {8 I0 F8 q/ W然後 service nginx restart  ======> OK
