这是用Squid 3.0设置的,也已经用Squid 3.1进行了测试,应该可以在Squid 2.7上使用。您的Windows用户必须是Active Directory中SQUID_USERS组的成员(无论如何,这种情况)。
在Windows方面,已经针对Windows 2008和Windows XP对Windows 2003进行了Windows XP和Windows 2007的测试。
请注意,几乎每个步骤都需要先执行该步骤。
如果您有问题,则DNS 始终是第一个查找的地方。两台Windows机器均应能够按名称ping Linux服务器(反之亦然),并且您可能ipconfig /flushdns
有时需要运行。如果您确实要确保没有死角,重新启动可能也会有所帮助。
dom.local
server.dom.local
,172.17.3.11
centos.dom.local
,172.17.3.10
dom.local
在DNS配置中创建反向区域。centos.dom.local
指向172.17.3.10
,当系统询问您是否还要设置反向PTR时,选择“ 是”。对于Windows 2008服务器,您需要安装Hotfix 951191。
安装套件
$ yum install -y cyrus-sasl-gssapi cvs autoconf automake openldap openldap-devel krb5-workstation krb5-devel gcc-c++
安装msktutil
。您需要先修补它,然后再构建它。
$ wget http://download.systemimager.org/~finley/msktutil/msktutil_0.3.16.orig.tar.gz
$ wget http://download.systemimager.org/~finley/msktutil/msktutil_0.3.16-7.diff.gz
$ gunzip msktutil_0.3.16-7.diff.gz
$ tar zxf msktutil_0.3.16.orig.tar.gz
$ cd msktutil-0.3.16
$ patch < ../msktutil_0.3.16-7.diff
$ ./configure && make && make install

ldap。
$ cvs -z3 -d:pserver:anonymous@squidkerbauth.cvs.sourceforge.net:/cvsroot/squidkerbauth co -P squid_kerb_ldap
$ cd squid_kerb_ldap
$ ./configure && make
用于system-config-network
将DNS点配置为域控制器,将主机名设置为centos.dom.local
。
重启
检查反向DNS是否正常工作:$ dig -x 172.17.3.10
您应该进入centos.dom.local
答案部分。如果不这样做,那就没有意义了。如果未正确配置DNS,则Kerberos身份验证将无法工作。
您krb.conf
应该看起来像这样:
[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log
[libdefaults]
default_realm = DOM.LOCAL
dns_lookup_realm = false
dns_lookup_kdc = false
ticket_lifetime = 24h
# For Windows XP:
default_tgs_enctypes = rc4-hmac des-cbc-crc des-cbc-md5
default_tkt_enctypes = rc4-hmac des-cbc-crc des-cbc-md5
permitted_enctypes = rc4-hmac des-cbc-crc des-cbc-md5
# For Windows 2007:
# default_tgs_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5
# default_tkt_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5
# permitted_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5
forwardable = yes
[realms]
DOM.LOCAL = {
kdc = 172.17.3.11:88
admin_server = 172.17.3.11:7491
default_domain = dom.local
}
[domain_realm]
.dom.local = DOM.LOCAL
dom.local = DOM.LOCAL
[appdefaults]
pam = {
debug = false
ticket_lifetime = 36000
renew_lifetime = 36000
forwardable = true
krb4_convert = false
}
创建密钥表:
$ kinit administrator
$ msktutil -c -b "CN=COMPUTERS" -s HTTP/centos.dom.local -h centos.dom.local -k /etc/HTTP.keytab --computer-name centos-http --upn HTTP/centos.dom.local --server server.dom.local --verbose
对于Windows 2008,您需要添加--enctypes 28
到msktutil
命令。
安装鱿鱼:
$ wget http://www.squid-cache.org/Versions/v3/3.0/squid-3.0.STABLE18.tar.gz
$ tar zxvf squid-3.0.STABLE18.tar.gz
$ cd squid-3.0.STABLE18
$ ./configure --enable-negotiate-auth-helpers=squid_kerb_auth --enable-stacktraces --prefix=/opt/squid-3.0
$ make
$ make install
$ cp helpers/negotiate_auth/squid_kerb_auth/squid_kerb_auth /opt/squid-3.0/sbin/
$ cp ~/squid_kerb_ldap/squid_kerb_ldap /opt/squid-3.0/sbin/
$ cd /opt/squid-3.0/
$ mv etc/squid.conf etc/squid.conf.ORIG
在squid.conf中设置适当的参数:
auth_param negotiate program /opt/squid-3.0/sbin/squid_kerb_auth -d -s HTTP/centos.dom.local
auth_param negotiate children 10
auth_param negotiate keep_alive o

pid_filename /var/run/squid-3.0.pid
cache_effective_user squid
cache_effective_group squid
coredump_dir /var/cache/squid-3.0
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
现在这很重要:Squid需要一些环境变量设置才能正常运行。最好的方法是使用初始化脚本。这是经过稍微编辑的CentOS:

# 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.

这些是重要的行:
KRB5_KTNAME=/etc/HTTP.keytab
export KRB5_KTNAME
centos.dom.local
使用port 将代理设置为服务器3128
。使用完全限定的域名而不是IP地址非常重要。
不必编辑/etc/init.d/squid来设置KRB5_KTNAME环境变量,您应该将行放在/ etc / sysconfig / squid中。由于初始化脚本在每次执行时都会输出/ etc / sysconfig / squid,因此它将选择这两行。
此外,您无需将主机明确命名为KDC和kadmin服务器,仅输入Active Directory域的DNS域就足够了。原因有两个:
按照这个教程,我可以让乌贼在fedora 12服务器上工作。检查Linux服务器上的防火墙(启用端口3128),并将SELinux设置为许可模式。
