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

當啟動nginx時, service nginx start (restart) 出現連續5個相同錯誤:
- k" z- D  D8 w3 Q[emerg] 5048#0: bind() to x.x.x.x:80 failed (98: Address already in use)
/ [6 R% j# w& Y; q0 ^0 J- R+ Y! ]最後再給你出現
[emerg] 5048#0: still could not bind()
$ O/ T3 a# v* ]  Z( f# p重開機也沒用
) d! s  [. s/ ?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)
% j# J3 d. C. b$ h3 p/ M查看是誰占用 port 80,但nginx也沒占用(啟動不了當然不會占用)

: f4 [" j4 N7 H/ e, j0 V
2 l. p9 e$ z$ }4 b- ]最後  fuser -k 80/tcp  刪除占用 port 80 的的所有程序(process)
然後 service nginx restart  ======> OK
