[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:
, K3 S6 M" u$ M1 P! H[emerg] 5048#0: bind() to x.x.x.x:80 failed (98: Address already in use)
8 U6 ~5 Q$ p8 _" j5 o$ e! ?最後再給你出現
[emerg] 5048#0: still could not bind()
# I! t* N! a' h* o7 Q$ z重開機也沒用
8 {  R4 G1 \1 T( {5 N9 D) o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)
查看是誰占用 port 80,但nginx也沒占用(啟動不了當然不會占用)
0 B( u$ L0 L/ Z/ D  q2 c
% P- M3 l. k& B6 a, b
: Z% R- r  r" T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
