Websphere报错"Cannot get canonical host name for server" 解决方法

今天帮人装一台Websphere,启动的时候报错:Cannot get canonical host name for server

[13-4-5 20:22:23:273 CST] 0000000a SystemErr     R Caused by: javax.naming.ConfigurationException: Cannot get canonical host name for server.

这是一个很常见,且简单的问题很明显是找不到主机名.检查系统主机名的配置文件

/etc/sysconfig/network
/etc/hosts

发现hosts文件里居然是空的~添加上

127.0.0.1 localhost.localdomain localhost

再启动一次. 成功~
