我正在尝试在docker容器中运行selenium测试。我在Oracle Linux 6.7的基本映像上创建了映像，并在其上安装了firefox 24。在入口点脚本中设置显示，该脚本也运行selenium测试。但是当它运行测试时，错误地说
[java] org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

[java] See the manual page for dbus-uuidgen to correct this issue.
[java] D-Bus not built with -rdynamic so unable to print a backtrace
这是我在入口点脚本中设置显示的方式
#Set the Display
vncserver :1
export DISPLAY=:1
有人可以告诉我可能做错了什么吗？
我做的其他信息和疑难解答： 我认为这可能是Firefox和Selenium的版本兼容性问题（使用selenium 2.44.0和firefox 24），但看起来并非如此。
