Nginx(二) nginx 無法啟動

有時候在客戶端輸入：nginx

但是終端會輸出以下，顯示啟動失敗

nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)
nginx: [emerg] still could not bind()

這時候可以輸入：ps -ef| grep nginx

 終端會輸出以下，顯示占用的端口

    0   551     1   0  9:22PM ??         0:00.01 nginx: master process nginx
   -2   614   551   0  9:26PM ??         0:00.00 nginx: worker process
    0   618   606   0  9:27PM ttys000    0:00.00 grep nginx

然后輸入：kill 551

來停止該端口進程。

再在終端輸入：nginx

然后在瀏覽器輸入：http://127.0.0.1:8080/

就會顯示啟動正常。
