关于错误：java.net.BindException: Cannot assign requested address

最近在centOS上面做j2ee开发，当启动tomcat7.0的时候总是报如下错误：

严重: StandardServer.await: create[localhost:8005]:

Threads are going to be renewed over time to try and avoid a probable memory leak.

在网上找了很多解决方法，都没有解决，然后我以后是项目工程改动的错误，但将项目从tomcat中去除后重启，还是不行，上网也有说是tomcat7的新问题，我换成6.0的版本后，还是不行，最后才记得可能是网络设置错误，我的解决方法出下：编辑/etc/hosts文件：

vim /etc/hosts

10.11.2.180 istore01 localhost

10.11.2.201 Dev01

10.11.2.202 Dev02

~
检查这里的IP地址是否和当前实际的地址相同，如果不相同，则改为当前的IP，我的情况就是本来我的IP是10.11.2.180的，但这个文件中记录的是192.168.0.180。这下找到这个问题了，记录在这里，让遇到相同问题的朋友也能快速解决问题。对了，以后我得养成写文章的习惯 了，帮助别人的同时也能对自己加深印象，虽然多花了点时间，我觉得还是值得的！！希望对有帮助的朋友回复下啊：）
