1.出现这个问题的原因可能是端口占用

　　　　tomcat没有 完全关闭进程还存在，杀死进程

　　　　其他软件占用相应端口 netstat -ano查看端口结束到，或者更改server.xml的默认端口

2.Cannot assign requested address的原因也有可能是localhost被路由到了别的机器。

 ping localhost看一下解析地址出不来 或者指向别的ip，打开/etc/hosts发现没有指定127.0.0.1的解析地址 

在/etc/hosts中添加指向到127.0.0.1的解析地址

127.0.0.1   localhost

重启tomcat
