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

IT_man

tid=34542&當啟動nginx時, service nginx start (restart) 出現連續5個相同錯誤:
' k3 N1 p! x- L# m( U$ }[emerg] 5048#0: bind() to x.x.x.x:80 failed (98: Address already in use)
4 z# B& j# i( r( {9 u最後再給你出現
+ P/ Q$ o: Z2 C  k# Z[emerg] 5048#0: still could not bind()
5 h4 R; r) @2 S; @* j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
/ _$ C- ~7 `/ t! r; Lfuser 80/tcp  (fuser 指令可以參考 http://nixgeek.com/finding-out-what-process-is-listening-on-a-port-under-linux.html)
& z/ y# A' |) y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)
然後 service nginx restart  ======> OK
