[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:
# J% ?3 }) `! g0 n[emerg] 5048#0: bind() to x.x.x.x:80 failed (98: Address already in use)
8 v* b0 p0 b; Y% E最後再給你出現
* z4 ?, ~1 w* l0 K- ]" _) `. C[emerg] 5048#0: still could not bind()
重開機也沒用
* Q6 U! H3 {$ w4 w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
2 P. d% a( ^7 o* F+ s; k* Efuser 80/tcp  (fuser 指令可以參考 http://nixgeek.com/finding-out-what-process-is-listening-on-a-port-under-linux.html)
查看是誰占用 port 80,但nginx也沒占用(啟動不了當然不會占用)
2 ^2 l8 T. q% K  k. j
6 w9 ~( c$ k# g
4 x" a1 C1 N! a8 H. Z) @# n+ G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
