查看hostname： 

[root@serv1 bin]# hostname  serv1  [root@serv1 bin]# hostname -i  未知的主机  在查看/etc/hosts  [root@serv1bin]# vi /etc/hosts  127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4  ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6   

解决方案：

其中没有hostname的映射，导致找不到主机。  ①修改hosts文件，添加主机的hostname即可：  [root@serv1 bin]# vi /etc/hosts  127.0.0.1    localhost localhost.localdomain localhost4 localhost4.localdomain4  ::1               localhost localhost.localdomain localhost6 localhost6.localdomain6       127.0.0.1    serv1

② 重启主机 reboot -n 

③ 重启tomcat服务
