启动Weblogic报java.net.UnknownHostException:……

 

问题：
java.lang.AssertionError: Could not obtain the localhost address. The most likely cause is an error in the network configuration of this machine.

java.net.UnknownHostException:localhost: localhost
 
发现有这么一句报错比较关键：
at weblogic.server.channels.AddressUtils$AddressMaker.getLocalHost(AddressUtils.java:40)
显然函数取值时出错。
 

解决办法：
$ cat /etc/hosts
/etc/hosts:Permission denied
$ ll /etc/hosts
-rw-------   1 root       root           744 Dec  8 15:36 /etc/hosts
$ su - root
# chmod 644 /etc/hosts
# ll /etc/hosts
-rw-r--r--   1 root       root           744 Dec  8 15:39 /etc/hosts

$cd /weblogic/bea/user_projects/domains/base_domain
$sh startWebLogic.sh
 
问题解决。
