[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：

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，提示不是立刻就有8005端口，要等一小会才会有。
[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

exit 0验证脚本：root下面正常；syadmin下面start正常，stop不正常；其他普通账号sysadm下面运行也有问题
脚本需要达到的目的是：
脚本在root下面可以正常运行，在设置的普通账号sysadmin可以运行，但是在非root账号非设置的sysadmin账号下面提示没有权限。

exit 0经过测试此启动脚本ok
此脚本经过使用过程中发现有bug，特意优化一下
第二次优化脚本如下：
tomcat-sbce脚本如下：
export JAVA_HOME、export PATH、CATALINA_HOME、TOMCAT_USER
其中CATALINA_HOME=/application/tomcat-sbce/目录后面一定要带/否则，tomcat_pid匹配的时候不精确，比如有两个实例tomcat-sbce和tomcat-sbce-h5,要确定每个pid进程的时候，使用ps -ef|grep /application/tomcat-sbce可以查看两个进程，不精确，所以要带完整路径ps -ef|grep /application/tomcat-sbce/才精确。
变化的只有这4个变量。
