今天在測試Nginx功能的時候，出現問題如下：

nginx: [emerg] bind() to 0.0.0.0:443 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 0.0.0.0:8083 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:7091 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:7092 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8081 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:1935 failed (98: Address already in use)

原因是：

在測試過程中，關閉過rtmp的端口號，./kill -9 pid(rtmp:1935)

結果在啟動 Nginx時，./nginx -c /usr/local/nginx/conf/nginx.conf

出現上述錯誤

結果過程如下：

首先用lsof -i:80看下80端口被什么程序占用。lsof返回結果如下：

[root@localhost sbin]# lsof -i:80
COMMAND ? PID USER ? FD ? TYPE ? DEVICE SIZE/OFF NODE NAME
nginx ? 63170 root ? ?9u ?IPv4 14243472 ? ? ?0t0 ?TCP *:http (LISTEN)

關閉進程：kill -9 ?63170

重新啟動Nginx：[root@localhost sbin]# ./nginx -c /usr/local/nginx/conf/nginx.conf

問題解決
