1.今天我想把tomcat中以前部署的一些项目删除，结果tomcat一直启动不了，可能哪里相关配置的原因，可以想不通会有这样的问题。后来直接加入一个小项目helloworld，改成webtest项目后，tomcat就启动了，好吧！我觉得是不是因为jenkins配置了webtest，又把webtest部署到这个tomcat上的原因，导致直接删除，tomcat找不到文件不能启动。有谁能提供更好的解答吗？
2.输入网址,端口，虽然到了tomcat页面，但是里面的web应用都已经不能正常访问

问题是该文件在该路径下，而且出现一个permission denied错误，所以找到该文件后修改权限
chmod 666 ××××，但是还是不能启动tomcat。无可奈何，在webapp中删除该应用，然后让jenkins构建项目，部署过去，正常使用，jenkins持续部署，没有问题。现在猜想是不是这样一个原因，是不是某一次提交的代码有问题，导致tomcat出故障，jenkins部署连接时有问题，后续的构建一直失败！有谁还可以提供这错误原因得大致分析吗？
谢谢
