Linux上部署apache-tomcat-6.0.18 启动报错

错误信息

SEVERE: StandardServer.await: create[8005]: java.net.UnknownHostException: localhost: localhostat java.net.InetAddress.getAllByName0(InetAddress.java:1128)at java.net.InetAddress.getAllByName0(InetAddress.java:1098)at java.net.InetAddress.getAllByName(InetAddress.java:1061)at java.net.InetAddress.getByName(InetAddress.java:958)at org.apache.catalina.core.StandardServer.await(StandardServer.java:373)at org.apache.catalina.startup.Catalina.await(Catalina.java:642)at org.apache.catalina.startup.Catalina.start(Catalina.java:602)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)at java.lang.reflect.Method.invoke(Method.java:585)at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:288)at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413)

测试方案：
ping 127.0.0.1 可以ping通
ping localhost 不通

说明是主机映射的原因。

解决方法： 修改etc/hosts 文件

[oracle@bogon ~]$ su - root
Password:
[root@bogon ~]# cd ..
[root@bogon /]# cd ..
[root@bogon /]# cd etc
[root@bogon etc]# cat hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 bogon.localdomain bogon

在hosts文件中追加下面一行就OK了：
127.0.0.1 localhost.localdomain localhost
