关于Tomcat无法启动以及无法访问小猫主页的问题排查

 在服务器部署web项目时，发现通过bin目录下的startup.bat启动一直闪退，可以看到在startup.bat调用catalina.bat的过程中可以看到有报错信息一闪而过，而后闪退，查看D:\apache-tomcat-7.0.77\logs目录下的日志文件：catalina.2018-06-06.log，日志记录如下：

可以发现是端口绑定的问题（win平台），查看端口占用情况netstat -ano，发现8080端口被占用，启动任务管理器，将javawe好像是这个名字的线程干掉，重启即可，除此以外，之前清理webapps文件夹的时候，莫名其妙在启动服务器后无法进入小猫的主页，发现webapps中的ROOT文件夹下除了一个web.xml文件别无他物，在服务器启动后的主页http://localhost:8080默认进入的是%tomcat%/webapps/ROOT，所以如果在误删ROOT下的文件后的情况下很可能导致服务器工程主页无法访问的情况，此时必须找到相应版本的tomcat再次解压将ROOT文件夹覆盖即可，重启便可看到小猫。
