今天在做LNMP的時(shí)候，啟動(dòng)nginx服務(wù)，無(wú)法開(kāi)啟，導(dǎo)致網(wǎng)頁(yè)打不開(kāi)。把服務(wù)從起一下發(fā)現(xiàn)提示錯(cuò)誤如下：

Starting nginx: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

問(wèn)題描述：地址已被使用?？赡躰ginx服務(wù)卡死了，導(dǎo)致端口占用，出現(xiàn)此錯(cuò)誤。

解決方法：首先用lsof:80看下80端口被什么程序占用。lsof返回結(jié)果如下：

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 3274 root 6u IPv4 10664 0t0 TCP *:http (LISTEN)
nginx 3547 nginx 6u IPv4 10664 0t0 TCP *:http (LISTEN)

發(fā)現(xiàn)是nginx程序，所以我們把nginx服務(wù)k掉，重新啟動(dòng)服務(wù)。。命令如下:

kill -9 3274

kill -9 3547

service nginx start

Starting nginx:                                            [  OK  ]

OK了，服務(wù)成功啟動(dòng)！~~
