各位：

  最近小弟在做squid代理的时候，遇到下面问题，请大家帮忙分析一下，squid用的tar包。系统用的是rhel5.3  ，

/etc/sysconfig/network  hostname  /etc/hosts 里面主机名都是一样的，slave.example.com

[root@slave etc]# service named restart
Stopping named: [  OK  ]
Starting named: [  OK  ]


[root@slave etc]# nslookup slave.example.com
Server:         192.168.1.2
Address:        192.168.1.2#53

Name:   slave.example.com
Address: 192.168.1.2


[root@slave etc]# nslookup 192.168.1.2
Server:         192.168.1.2
Address:        192.168.1.2#53

2.1.168.192.in-addr.arpa        name = slave.example.com.


[root@slave etc]# cat /etc/resolv.conf
nameserver 192.168.1.2


[root@slave etc]# /usr/local/squid/sbin/squid -NCd1

呵呵，我的问题都是你来回答啊。上面的问题已经弄好了，我dns开了chroot，所以我在/etc/named.*都是来自/var/named/chroot/etc/named.*的软连接，其中一个连接处了问题，虽然dns能启动。不过现在又有个新问题，我在弄弄，如果弄不好再请教版主。

在/usr/local/squid/var/logs和/usr/local/squid/var/cache下面会生成如下文件。而且此时squid是运行状态

如果人为停止/usr/local/squid/sbin/squid -NCd1 命令，会提示如下内容。而且squid进程将停止运行
