[root@devops01-web-53 scripts]#tomcat启动的时候看不出异常，关闭的时候回报错类似：
SEVERE: Could not contact localhost:8005. Tomcat may not be running.
即为8005端口未运行，使用命令netstat -ant 发现 没有找到8005端口
[root@devops01-web-53 scripts]# netstat -lntup|grep java tcp 0 0 :::8009 :::* LISTEN 10373/java tcp 0 0 :::8080 :::* LISTEN 10373/java
解决办法：
修改$JAVA_HOME/jre/lib/security/Java.security 文件中 securerandom.source 配置项:
将 securerandom.source=file:/dev/random 修改为： securerandom.source=file:/dev/urandom（网上查询的结果，我改完这个就可以了，下面的未测试） 如果，仍然不生效，则修改为： file:/dev/./urandom
实战如下：
[root@devops01-web-53 scripts]# vim /usr/java/jdk/jre/lib/security/java.security securerandom.source=file:/dev/random 修改为 securerandom.source=file:/dev/urandom
再次启动tomcat就有8005端口了
[root@devops01-web-53 scripts]# netstat -lntup|grep java tcp 0 0 ::ffff:127.0.0.1:8005 :::* LISTEN 10615/java tcp 0 0 :::8009 :::* LISTEN 10615/java tcp 0 0 :::8080 :::* LISTEN 10615/java
最后脚本被修改为：
验证脚本：
脚本在root下面可以正常运行，在设置的普通账号可以运行，但是在非设置非root提示没有权限。
