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)
" L, B$ |8 H+ f+ H% W& i最後再給你出現
[emerg] 5048#0: still could not bind()
9 q1 \/ L4 {+ r; r8 U# P重開機也沒用
% x: U) n3 ^) ^* I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)
