MQTT服务端程序部署，tomcat一直启动，卡着不动了

公司有个项目，需要做个云喇叭系统，用户在喇叭上按按钮，触发指令到服务端，服务端收到指令后给云喇叭发消息，云喇叭播报消息。最后决定用MQTT技术，现在服务端的程序在测试研发环境调试都通过了，但是部署到服务器上出了问题。测试研发环境是在windows开发环境下的tomcat8.5，能正常运行。

MQTT的服务端程序是java开发的，生产环境是linux服务器，tomcat8.5，tomcat服务一直出于启动中，服务访问不了，好像卡死了一样，麻烦大佬帮忙看看是怎么回事。tomcat启动日志如下：

这时tomcat也不能关闭，只能通过kill进程的方式关闭，小弟刚刚接触mqtt，请大佬帮忙看看

1、在tomcat的bin/catalina.sh中加入这么一行：JAVA_OPTS="-Djava.security.egd=file:/dev/./urandom" 即可。　　

       2、jvm环境：打开$JAVA_PATH/jre/lib/security/java.security这个文件，找到下面的内容：

　　　　securerandom.source=file:/dev/urandom

　　　　替换成

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

试试看这篇文章能不能解决，https://blog.csdn.net/sq_bang/article/details/57086263，另外还要注意在代码里面没有引用特殊的windows的特性的东西

有没有等过，也许是启动时间相当长
