[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:
: b$ ?  I- b2 f$ g; ~. @" e" i[emerg] 5048#0: bind() to x.x.x.x:80 failed (98: Address already in use)
9 Z& e) R: d" H' E7 u/ m" x最後再給你出現
; i/ _' O$ y$ M; Z/ e6 u$ T[emerg] 5048#0: still could not bind()
重開機也沒用
. _- L3 I# l; t/ r' f( S% d2 C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
0 \4 W) c( _5 u' x& |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)
" D; \: [. q% r! O查看是誰占用 port 80,但nginx也沒占用(啟動不了當然不會占用)
' S& n1 [1 j: y# |& ~, L

. r* S! `/ V% d* F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
