windows-server-2008 – 让squid通过kerberos和Windows 2008/200

设置用户和目录：

$chown -R squid:squid /opt/squid-3.0/
$mkdir /var/cache/squid-3.0
$chown -R squid:squid /var/cache/
$mkdir /var/log/squid-3.0
$chown -R squid:squid /var/log/squid-3.0/
$chown squid:squid /etc/HTTP.keytab

创建缓存：

$/opt/squid-3.0/sbin/squid -z

初始化脚本

现在这很重要：Squid需要一些环境变量设置才能正常运行.执行此操作的最佳方法是使用init脚本.这是一个略有编辑的CentOS：

#!/bin/bash
# squid     This shell script takes care of starting and stopping
#       Squid Internet Object Cache
#
# chkconfig: - 90 25
# description: Squid - Internet Object Cache. Internet object caching is 
#   a way to store requested Internet objects (i.e.,data available 
#   via the HTTP,FTP,and gopher protocols) on a system closer to the 
#   requesting site than to the source. Web browsers can then use the 
#   local Squid cache as a proxy HTTP server,reducing access time as 
#   well as bandwidth consumption.

exit $?

这些是重要的路线：

KRB5_KTNAME=/etc/HTTP.keytab
export KRB5_KTNAME

客户端机器

使用端口3128将代理设置为服务器centos.dom.local.使用完全限定的域名而不是IP地址非常重要.
