最近在centOS上面做j2ee開發，當啟動tomcat7.0的時候總是報如下錯誤：

在網上找了很多解決方案，都沒有解決，然後我以後是項目工程改動的錯誤，但將項目從tomcat中去除後重啟，還是不行，上網也有說是tomcat7的新問題，我換成6.0的版本後，還是不行，最後才記得可能是網路設定錯誤，我的解決方案出下：編輯/etc/hosts檔案：
vim /etc/hosts
10.11.2.180 istore01 localhost
10.11.2.201 Dev01
10.11.2.202 Dev02
~
檢查這裡的IP地址是否和當前實際的地址相同，如果不相同，則改為當前的IP，我的情況就是本來我的IP是10.11.2.180的，但這個檔案中記錄的是192.168.0.180。這下找到這個問題了，記錄在這裡，讓遇到相同問題的朋友也能快速解決問題。對了，以後我得養成寫文章的習慣 了，協助別人的同時也能對自己加深印象，雖然多花了點時間，我覺得還是值得的！！希望對有協助的朋友回複下啊：）
