我无法启动我的Iot代理。它曾经工作过。可能是什么问题？
这是我的启动脚本（上下文代理在192.168.1.126下运行）：
export LD_LIBRARY_PATH=/usr/local/iot/lib
/usr/local/iot/bin/iotagent -i 192.168.1.126 -p 80 -v DEBUG -d /usr/local/iot/lib -c /etc/iot/config.json &
这是我的config.json文件：
{
"resources": [
{
"resource": "/iot/kuraResources",
"options": {
"FileName": "UL20Service"
}
}
],
"timezones": "/etc/iot/date_time_zonespec.csv",
"storage": {
"type": "mongodb",
"dbname": "iot"
},
"ngsi_url": {
"cbroker": "http://192.168.1.126:1026",
"updateContext": "/NGSI10/updateContext",
"registerContext": "/NGSI9/registerContext",
"queryContext": "/NGSI10/queryContext"
},
"timeout": 11,
"dir_log": "/var/log/"
}
当我尝试启动它时，这是我的日志：
[root@localhost iot]# sudo ./ini_iotagent.sh

另一个进程不使用端口80。我测试了另一个端口，但错误仍然存在：

似乎端口80正被另一个进程使用。
通过执行以下命令，您可以知道哪个进程正在侦听端口80：
netstat -lnp | grep 80
如果正在使用端口80，您可以在另一个端口上启动iotagent，例如端口8080：
/usr/local/iot/bin/iotagent -i 192.168.1.126 -p 8080 -v DEBUG -d /usr/local/iot/lib -c /etc/iot/config.json &

我对启动脚本中指定的Iot代理IP地址错误。
感谢您的帮助。
