[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:
* v! Q* R4 _8 J6 }# j[emerg] 5048#0: bind() to x.x.x.x:80 failed (98: Address already in use)
( q; C4 b: J) L# V/ i最後再給你出現
/ S: h4 N) a) M* o[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)
: [, x0 @  G9 W% J/ q, {- _查看是誰占用 port 80,但nginx也沒占用(啟動不了當然不會占用)
. O( g/ |3 e$ U
' U( h/ s" f/ g
! M& m4 R; z$ c+ `% d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
