Raspbian中的OpenHAB：無法連接：連接被拒絕

Question

當我瀏覽到http：// localhost：8082 / openhab.app？sitemap = demo時 ，出現以下錯誤（即使在清除了完整的歷史記錄緩存和cookie之后）：

Could not connect: Connection Refused.

ls -l顯示-rwxrwxrwx root root為demo.sitemap在文件sitemaps的文件夾openhab 。

所以當我做sudo netstat -tulpn | grep 8082 sudo netstat -tulpn | grep 8082沒有顯示任何內容，但我收到此錯誤：

FAILED SelecyChannelConnector@0.0.0.0:8082:java.net.BindException: Address Already in use.

我已經在使用8080的整個openhab文件夾中的任何位置使用了8082 。 知道如何解決嗎？

sudo lsof -i :8080顯示以下內容：

pi@raspberrypi:~ $ sudo lsof -i :8080
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 756 openhab 128u IPv6 12383 0t0 TCP *:http-alt (LISTEN)

而：

pi@raspberrypi:~ $ sudo lsof -i :8082
pi@raspberrypi:~ $

我有些困惑，因為我想在端口8082而不是端口8080上運行openHAB。

我在以下文件中將8080更改為8082 。 請讓我知道這是錯的嗎？

我正在使用OpenHAB version 1.8.1

Answer 1

HTTP_PORT在start.sh或start_debug.sh更改HTTP_PORT變量start_debug.sh 。 也可以使用8082而不是8080 ，而且我可以打開UI。

可以肯定的是：您在url中使用了localhost ，但是openhab在Raspberry Pi上運行。 這是否意味着您在Pi本身上使用的是瀏覽器？

Answer 2

因為我是OpenHAB的新手，所以我既手動安裝了它，也從apt-get中安裝了它，所以apt-get中的一個已安裝到/usr/share/openhab並且在后台運行，並且每次都自動啟動。 我通過'$ sudo /etc/init.d/openhab stop'命令停止了它。 我還檢查了是否有人在運行端口之前使用了8080或8082（ sudo lsof -i :8080 ）。 您只需要在start.sh文件中指定，而無需在openhab_default.cfg或openhab.cfg文件中指定，您想通過start.sh文件中的HTTP_PORT=8082使用8080以外的其他端口。

Remove openhab from autostart:
sudo update-rc.d openhab remove
