Cannot connect to rapidminer-server

sbuschjaeger

Hi,

I just installed rapidminer-server on a linux machine which seems to work. However, I cannot access the web interface to manage the server.
I followed the installer GUI and installed rapidminer-server on my local machine. The MySQL connection to 'localhost' worked without any problems. I did not configure a SMTP server. Installation was done into my local home folder without root privileges. Startup looks like this:

[10:52:54]~/tools/rapidminer-server/bin$ ./standalone.sh

When I try to connect to to 'localhost:8080' from the same machine, I get "unable to connect". And indeed, 'lsof -i' doesnt show any port 8080. I double checked the configuration file
"standalone.xml" which contains
""
, so everything should be setup correct. However, I doesnt work

年代ome additional system information:

任何想法为什么这不是工作吗?

Hi,

RM服务器还没有使用Java 8。请我们e Java 7 instead as indicated on our system requirements page:http://docs.www.kenlockard.com/server/installation/system-requirements.html

Regards,
Marco

Hello everyone,

I have the same problem. I cannot be connected to the RapidMiner Server from the Web interface. I have checked my IP address and i use the same Repository URL as i used to do the previous days.

Thanks in advance for your help!

Hi. You cannot connect from Studio to Server or from your browser to the Server's web interface? Did Server start correctly? Let's have a look into the the server.log file in the RapidMiner Server home directory. Is your network able to connect to the IP address of Server? Maybe try with a ping or the telnet command in the command prompt? Have you maybe changed the listen/bound to property to 127.0.0.1/localhost in the installer?.
