my rstudio server was hanging too often while loading starting r shiny app. So after googling around i tried to stop and start the rstudio server again. i also tried to kill all process running on 8787 port. But had no luck solving the issue. now r studio server keeps waiting while opening on web browser.
I have used below command to kill process running on 8787 port. after running the command there was no result.
sudo kill -TERM 20647
(20647 is port where rserver process is listening. i got this port number after running 'sudo netstat -ntlp | grep :8787' command).
to stop and restart r studio server, i used below command
sudo rstudio-server stop
sudo rstudio-server start
expected result is working sr studio server which doesnt hang while loading shiny app.
after running status command i found below error logged for rstudio server.

I have installed freeradius on Centos 8. I installed it and it worked just fine but after installing mariaDB, issues came out when trying to start the service.

I'm following this YouTube Tutorial to setup my Server with Flask and Nginx: https://www.youtube.com/watch?v=o2WA-A67Bks&t=360s
Right now I'm at the Gunicorn part. I tried to start following commands:
systemctl daemon-reload
systemctl start index
systemctl enable index
systemctl status index
But it doesn't work. The Error Message looks like this:

I had setup my nginx server fine last week until I noticed I was receiving DOSS attacks against it. I then noticed at this point my Nginx server was failing to start. I have tried everything else and unsure what to do to resolve the issue apart from reading documentation which does not help.
Documentation on Nginx
main nginx.conf appears to be empty and I cannot save to it for some reason.

Removed Nginx from ubuntu and done a clean installation onto server. Managed to sort the server blocks out this time so all good.
I am installing Apache cloudstack on ubuntu 16.0.4, but after installing cloudstack setup when I start services of cloudstack management service it displayed the following errors. (I have installed tomcat7, but tomcat 6 is not installed)

No details on this log.
My yaml configuration has only this props:
server.port: 5601
server.host: "0.0.0.0"
I also have tried writing to a log file(hoping for more info there), I tried adding this configurations:
logging.dest: /var/log/kibana/kibana.log
logging.verbose: true
I gave the folder/file full access control but nothing is being written there(still writing to the stdout)
