用户认证功能的SQUID代理服务器

SQUID和MYSQL的安装采用了SUN发布的二进制安装包，它在software_companion_x86 CD中可以找到；MYSQL_AUTH用GOOGLE搜索就可以找到。

一、安装配置SQUID+MYSQL

1.建立用户和组

# groupadd squid

# useradd -g squid -d /dev/null -s /bin/false squid

# groupadd mysql

# useradd -g mysql -s /bin/false mysql

2. 安装MYSQL

# mount –F hsfs –o ro /dev/dsk/c1t0d0p0 /cdrom

# cd /cdrom/components/i386/Packages

# pkgadd -d ./ -s /var/spool/pkg SFWmysql SFWgcmn

# pkgadd SFWgcmn SFWmysql

# chown -R root /opt/sfw/mysql

# chgrp -R mysql /opt/sfw/mysql

# chown -R mysql /opt/sfw/mysql/var

# /opt/sfw/mysql/bin/mysql_install_db

# /opt/sfw/mysql/bin/mysqld_safe &

# cp /opt/sfw/mysql/share/mysql/my-medium.cnf /etc/my.cnf

# vi /etc/my.cnf

bind-address = 127.0.0.1

设置启动脚本：

# cp /opt/sfw/mysql/share/mysql/mysql.server /etc/init.d/mysql.server

# ln /etc/init.d/mysql.server /etc/rc3.d/S79mysql

# ln /etc/init.d/mysql.server /etc/rc0.d/K00mysql

# ln /etc/init.d/mysql.server /etc/rc1.d/K00mysql

# ln /etc/init.d/mysql.server /etc/rc2.d/K00mysql

# ln /etc/init.d/mysql.server /etc/rcS.d/K00mysql

# chown root:sys /etc/init.d/mysql.server /etc/rc3.d/S79mysql

# chmod 0744 /etc/init.d/mysql.server /etc/rc3.d/S79mysql

设置ROOT密码：

# mysqladmin -u root password llzqq

3．安装SQUID

# pkgadd -d ./ -s /var/spool/pkg SFWsquid

# pkgadd SFWsquid

# cd /opt/sfw/squid/etc

# cp squid.conf.default squid.conf

# cp mime.conf.default mime.conf

4.配置SQUID.CONF

http_port 192.168.0.1:3128

cache_mgr llzqq@nero.3322.org

error_directory /opt/sfw/squid/share/errors/Simplify_Chinese

dns_nameservers 202.99.160.68 202.99.168.8

visible_hostname nero.3322.org

httpd_accel_uses_host_header on

httpd_accel_host virtual

httpd_accel_port 80

httpd_accel_with_proxy on

cache_mem 20 MB

maximum_object_size 4096 KB

minimum_object_size 0 KB

maximum_object_size_in_memory 30 KB

minimum_object_size_in_memory 0 KB

cache_swap_low 85

cache_swap_high 90

cache_dir ufs /opt/sfw/squid/var/cache

cache_effective_user squid

cache_effective_group squid

#http_access allow manager localhost

#http_access allow localhost

#http_access deny manager

#http_access deny !Safe_ports

#http_access deny CONNECT !SSL_ports

#http_access deny all

http_reply_access allow all

icp_access allow all

miss_access allow all

--------------------------------------------------------

# chown –R squid:squid /opt/sfw/squid/var

# /opt/sfw/squid/sbin/squid -z

5. SQUID启动脚本

# vi /etc/rc3.d/S78squid

====================== S78squid =====================

#!/sbin/sh

#

# Copyright (c) 2004 by llzqq, Inc

# llzqq@126.com

# All rights reserved.

#

#ident '@(#)squid 1.1 04/05/24 SMI'

case '$1' in

start)

/opt/sfw/squid/sbin/squid -s

;;

stop)

/opt/sfw/squid/sbin/squid -k shutdown

pkill squid

;;

*)

echo 'Usage: $0 { start | stop }'

exit 1

;;

esac

exit 0

====================== S78squid =====================

# chown root:sys /etc/rc3.d/S78squid

# chmod 744 /etc/rc3.d/S78squid

# ln -s /etc/rc3.d/S78squid /etc/rc2.d/K78squid

二、 安装MYSQL_AUTH

# gzip -d mysql_auth-0.6beta.tar.gz

# tar vxf mysql_auth-0.6beta.tar

# cd mysql_auth-0.6beta

Makefile中需要修改的内容如下：

# vi Makefile

CFLAGS = -I/opt/sfw/mysql/include -L/opt/sfw/mysql/lib/mysql

INSTALL = /usr/ucb/install

$(INSTALL) -o root -g sys -m 700 mypasswd /usr/local/bin/mypasswd

$(INSTALL) -o squid -g squid -m 755 mysql_auth /usr/bin/mysql_auth

$(INSTALL) -o squid -g squid -m 600 $(CONF) /etc/mysql_auth.conf

$(INSTALL) -o squid -g squid -m 600 $(CONF) /etc/mysql_auth.conf.default

src/define.h中需要修改的内容如下：

# vi +5 src/define.h

#define CONFIG_FILE '/etc/mysql_auth.conf'

#define DEF_MYSQLD_SOCKET '/tmp/mysql.sock'

src/mysql_auth.conf中需要修改的内容如下：

# vi src/mysql_auth.conf

mysqld_socket /tmp/mysql.sock

# /usr/ccs/bin/make

# /usr/ccs/bin/make install

创建用户数据库：

# cd scripts

# mysql -u root -p****** < create_script

测试MYSQL_AUTH

1.添加一个测试用户

# mypasswd llzqq 123456

Password record ADDED succesfully.

2.验证刚才建立的用户

# mysql_auth

llzqq 123456

0K

3.删除一个已经建立的用户用这个命令

# mypasswd –d username

三、在SQUID.CONF中增加MYSQL_AUTH认证部分

# vi /etc/squid/squid.conf

添加下面的代码到SQUID.CONF中“TAG: acl”一节的后面

auth_param basic program /usr/bin/mysql_auth

auth_param basic realm LLZQQ’S CACHING SERVER

auth_param basic children 5

auth_param basic credentialsttl 2 hours

acl password proxy_auth REQUIRED

http_access allow password

authenticate_ip_ttl 2 hours

http_access deny all

四、客户端设置

在浏览器的代理服务器设置中填写SQUID服务器的IP和端口：

192.168.0.1:3218

在下载软件FLASHGET的代理服务器设置中填写SQUID服务器的IP、端口、用户和密码：

192.168.0.1:3218

user:llzqq

passwd:123456

五、注意事项

在进行以上安装前要先安装GCC否则不能编译MYSQL_AUTH，另外在添加用户前需要设置ROOT用户的LD_LIBRARY_PATH变量中有这个路径：/opt/sfw/mysql/lib/mysql
