apache zeppelin已启动，但在localhost:8080中存在连接错误

问题描述

在Ubuntu 14上成功构建apache zepellin之后，我启动zeppelin，它说成功启动，但是当我进入localhost:8080时，Firefox显示无法连接错误，就像它没有启动一样，但是当我从终端检查Zeppelin状态时，它说正在运行，我也只是复制了配置文件模板，所以配置文件是默认的

after successfully build apache zepellin on Ubuntu 14, I start zeppelin and it says successfully started but when I go to localhost:8080 Firefox shows unable to connect error like it didn't started but when I check Zeppelin status from terminal it says running and also I just copied config files templates so the config files are the default

将端口更改为8090，这是配置文件，但结果未更改

changed the port to 8090 , here is the config file , but no change in result

这是启动齐柏林飞艇后处于侦听状态的端口

and here are the ports which are in listening state after zeppelin is started

tcp6       0      0 :::8081                 :::*                    LISTEN
tcp6       0      0 ::1:631                 :::*                    LISTEN
tcp6       0      0 :::8091                 :::*                    LISTEN
tcp6       0      0 :::9001                 :::*                    LISTEN

和Zeppelin is running [ OK ]是运行命令bin/zeppelin-daemon.sh status

and Zeppelin is running [ OK ] is the response I get when I run command bin/zeppelin-daemon.sh status

推荐答案

检查是否可以在127.0.0.1:8080到达它.这对我有用，而localhost:8080也无法访问.

Check if you can reach it at 127.0.0.1:8080. This works for me, while localhost:8080 also is not reachable.
