解决centos下启动tomcat的时候一直卡在INFO: Deploying web application

在用centos7.+不熟tomcat项目的时候,启动时突然很奇怪的没报错,但是又访问不了网址,调用./shutdown.sh又结束不了,一直出现:
java.net.ConnectException: Connection refused (Connection refused)
    at java.net.PlainSocketImpl.socketConnect(Native Method)
    at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350)
    at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206)

一定要用kill命令才结束地了:

ps -aux | grep java
kill -9 19562
后面查了相关博客才发现,其实是centos7.+本身安全性的问题,需要改安装jdk源文件,找到java.security :

vi /usr/java/default/jre/lib/security/java.security
中的

securerandom.source=file:/dev/urandom
改成:

securerandom.source=file:/dev/./urandom
即可解决问题 (责任编辑:IT)
