Configure the environment is: CentOS + Tomcat 7 8
A few days before the project reason need to deploy a war file, test whether can normal open,
But oddly, deploy Tomcat after every time manually shut down will be submitted to the following error:

Can certain is that, before the deployment of war file, there is no question of Tomcat,
So I on the Internet to find solutions to find for a long time, most say it's because the port 8005 start too slow (when calculating the random number block)
. The solution is to modify the Java security, this file will be securerandom. The source of this changed to:
Securerandom. Source=file:/dev/./urandom
Good,
However I tried find still won't do...
So for this problem and made two days still didn't understand, depressed for a long time,
Until one day I put the virtual machine network adapter by NAT connection mode is changed to bridge mode and replicate physical network connection state,
The problem is solved
Now I am still a face of meng, so far all don't know why,
