[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:
[emerg] 5048#0: bind() to x.x.x.x:80 failed (98: Address already in use)
4 v% N: K% x8 ^! M3 Q! p& T6 F' T最後再給你出現
[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)
0 T: e* Z$ G5 K+ T1 v+ I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; M/ s1 ?- \
. @7 D/ a1 [3 _) @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
