SSH Resource Manager Deployment

[Mr. Moritz Burmester__0001 0]

Hello guys,

i am trying to get the ssh resourse manager to work on my ubuntu 16.04 sever.

I followed the instructions in the adminguide, but something seems to be wrong.

 

The java application does start, but trying to access the webpage shows this:

 

 

the console output looks like this:

I spent hours trying to find solutions on the internet but didn't have any success.Can anyone help me with this?

Thanks in advance!

Hi Moritz,

 

this problem is probably due to a version clash of your mariaDB database and the corresponding JDBC driver. You probably have mariaDB 10.1. Try to install the lastest mariaDB version (10.3) which is provided on the download page of mariaDB.

 

By the way your current student license will not allow you to use the resource manager. I will send you an email.

 

best regards

 

Carsten
