[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:
% a) M' E" e  @5 m  C[emerg] 5048#0: bind() to x.x.x.x:80 failed (98: Address already in use)
$ ?: U# _8 z4 _最後再給你出現
[emerg] 5048#0: still could not bind()
5 _* J" g4 R% K" \  W$ s" Q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
# ?: B7 ~5 T9 Tfuser 80/tcp  (fuser 指令可以參考 http://nixgeek.com/finding-out-what-process-is-listening-on-a-port-under-linux.html)
  Q0 q( z' [1 |) d查看是誰占用 port 80,但nginx也沒占用(啟動不了當然不會占用)

* \" @. J( s# e: o  d! m9 |1 Z
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
