tomcat debug模式启动失败

错误：
ERROR: transport error 202: gethostbyname: unknown host
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/ws/back/debugInit.c:690]
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)

在/etc/hosts下面添加
127.0.0.1 localhost.localdomain localhost
上面一行就行了。
应该是localhost没有映射到127.0.0.1的缘故。因为eclipse调试的时候会连接localhost的.
