Linux系统下，Tomcat启动有时报Address already in use<null>:8080
我知道 是端口被占用，可是第一次启动就是成功的，再关闭后，重启就报错，具体错误码信息如下：

这个项目里面使用的数据库是Sybase，另：在配制 Tomcat 时，那个文件夹名字有个空格怎么设置可以有效？
[解决办法]
那是因为你的tomcat已经启动了 tomcat自带的关闭脚本 有时候关闭看上去成功了 其实并没有关闭了
你可以ps -ef
[解决办法]
grep java查看 如果还在 就用kill -9 pid把它杀掉 再启动tomcat
另外在linux下 尽量避免用带空格的文件名 文件夹 容易搞错 在使用空格的时候加转义字符\ 即\空格
