linux 修改host后启动tomcat报错
错误: 代理抛出异常错误: java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: centos4: centos4: 未知的名称或服务
Error: Exception thrown by the agent : java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: centos4: centos4: Name or service not known
原因是/etc/hosts文件里没有主机名为：centos4，解决方法就是在hosts文件中加入centos4，修改后的hosts的文件是：
127.0.0.1 centos4 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
