squid (Version 2.5.STABLE5)的问题

horseman1214

debian linux 2.6.3

安装了squid 2.5.STABLE5,配置完启动出现下面的提示:

/usr/local/squid/sbin/squid -z
FATAL: Could not determine fully qualified hostname.  Please set 'visible_hostname'

Squid Cache (Version 2.5.STABLE5): Terminated abnormally.
CPU Usage: 0.007 seconds = 0.004 user + 0.003 sys
Maximum Resident Size: 0 KB
Page faults with physical i/o: 0
Aborted

实际上我在/etc/squid/squid.conf中，已经加了
visible_hostname xxxxx

其中，xxxxx我用了主机名，IP地址,任意名字，都不行。请问各位，如何解决。
