Tomcat启动时卡在“INFO: Deploying web application directory ......”的解决方法

启动tomcat时，一直卡在

root@iz8vbdzx7y7owm488t4d89z bin]# tail -f ../logs/catalina.out
09-Jun-2017 15:57:06.666 INFO [main] org.apache.coyote.AbstractProtocol.init Initializing ProtocolHandler ["ajp-nio-8009"]

的解决办法：

永久：oracle 说修改 $JAVA_HOME/jre/lib/security/java.security 文件，替换securerandom.source=file:/dev/random 为 securerandom.source=file:/dev/urandom。对所有使用JVM的应用生效。（这个永久的方法，这里面有个问题，就是设置时候实际应该设置为securerandom.source=file:/dev/./urandom，否则不生效）
