Solve the problem that tomcat is stuck in INFO: Deploying web application when started in centos.

When centos7. + is not familiar with the tomcat project, when it is started, it is suddenly strange that no error is reported, but the website cannot be accessed../shutdown.shBut it cannot end. It always appears:

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)    at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188)    at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392)    at java.net.Socket.connect(Socket.java:589)    at java.net.Socket.connect(Socket.java:538)    at java.net.Socket.<init>(Socket.java:434)    at java.net.Socket.<init>(Socket.java:211)    at org.apache.catalina.startup.Catalina.stopServer(Catalina.java:498)    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)    at java.lang.reflect.Method.invoke(Method.java:498)    at org.apache.catalina.startup.Bootstrap.stopServer(Bootstrap.java:343)    at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:430)

You must use the kill command to end the process:

ps -aux | grep javakill -9 19562

After checking the relevant blog, I found that it is actually a security issue of centos7. +. You need to install the jdk source file and find java. security:

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

In

securerandom.source=file:/dev/urandom

Changed:

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

You can solve the problem.
