用户认证功能的SQUID代理服务器

领测软件测试网

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
