Selenium独立服务器无法启动

Question

我在VPS上启动selenium独立服务器时遇到了麻烦

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

输出:

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

之后再没有输出了.在本地,相同的命令就像魅力一样.任何提示如何解决这个问题？

Java的

root@PIV:/usr/share/nginx/pivdev/tests# java -version
java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.14.04.1)

该服务根本没有在任何端口上运行

Netstat输出

好吧,这里的主要问题是selenium服务器在启动时遇到困难,我不知道为什么.我摧毁了我的VPS机器并从头开始.selenium服务器启动一次,在我停止并再次启动之后问题发生了(并且在重启后仍然存在).有时它甚至在第一次尝试时也不起作用.

我不确定它是java问题还是selenium服务器问题还是我的VPS主机问题.

长短篇小说:

Selenium使用/ dev/random(不知道为什么,不要问)并且它正在等待足够的熵来生成随机数.

固定

只需在启动selenium时添加参数:-Djava.security.egd=file:///dev/urandom switch你就可以了
