Tomca启动脚本遇到的坑

tomcat脚本：

原始脚本：

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-53scripts]#netstat-lntup|grepjava
tcp00:::8009:::*LISTEN10373/java
tcp00:::8080:::*LISTEN10373/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-53scripts]#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-53scripts]#netstat-lntup|grepjava
tcp00::ffff:127.0.0.1:8005:::*LISTEN10615/java
tcp00:::8009:::*LISTEN10615/java
tcp00:::8080:::*LISTEN10615/java

验证8005端口延时启动过程：

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。

实际验证操作：有的机器8005可以立马启动，有的是延迟启动
