Selenium standalone server does not start

I'm having problems starting a standalone selenium server on my VPS

root@PIV :/usr/share/nginx/pivdev/tests# java -jar selenium-server.jar

Output:

 21:53:08.857 INFO - Launching a standalone Selenium Server 21:53:08.911 INFO - Java: Oracle Corporation 24.79-b02 21:53:08.914 INFO - OS: Linux 3.13.0-52-generic amd64 21:53:08.945 INFO - v2.47.1, with Core v2.47.1.

After that, it is no longer displayed. Locally, the same team works like a charm. Any hint on how to solve this problem?

Java

Update 1

The service does not work at all on any port

Netstat Output

Update 2

Well, the main problem here is that the selenium server is stuck at startup, and I don't know why. I destroyed my VPS machine and started from scratch. The selenium server booted up once, after I stopped and started the problem again (and persists after reboot). Sometimes it does not work even on the first try.

I am not sure if this is a java problem or a problem with selenium server or a problem with a VPS host.

Long story:

Selenium uses / dev / random (I don’t know why, don’t ask), and he expected enough entropy to generate a random number.

CORRECTION

Just add a parameter when starting selenium: -Djava.security.egd=file:///dev/urandom switch , and you're good to go

When running on linux, it is better to start the selenium server with some of the features listed below:

 java -jar selenium-server.jar -Dwebdriver.chrome.bin=/path/to/google-chrome -Dwebdriver.chrome.driver=/path/to/chromedriver -browser browserName=chrome platform=LINUX -port 4444

Also, not sure if your local system is Linux.
