ubuntu下的squid

1.安装linux系统,选择自定义安装,选择开发工具包,webSERVER服务,去掉squid，安装的时候把SELINUX选成DISABLE

 

你也可以不用做以下的步骤,用我提供的脚本安装一下的一些配置!!!把setup.tar.bz2拷贝到

/root目录下,然后用

tar –jxvf setup.tar.bz2

cd ./setup

sh ./setup

这三个命令就可以完成下面的配置了.安装完毕后系统会重新启动,启动后进入系统,配置ipmacfile文件(ip与mac地址绑定文件)和初始化你用户和密码(具体请看服务器使用说明)

 

 

2.下载源代码并解压

 

cd /usr/src

wget -c http://www.squid-cache.org/Versions/v2/2.5/squid-2.5.STABLE14.tar.gz

tar -zxvf squid-2.5.STABLE14.tar.gz

 

 

3.安装Squid Proxy Server

 

cd /usr/src/squid-2.5.STABLE14

 

./configure --prefix=/usr/local/squid --sysconfdir=/etc/squid --bindir=/usr/bin --sbindir=/usr/sbin --mandir=/usr/share/man --enable-gnuregex --enable-carp --enable-async-io=80 --enable-removal-policies=heap,lru --enable-icmp --enable-delay-pools --enable-useragent-log --enable-referer-log --enable-kill-parent-hack --enable-snmp --enable-arp-acl --enable-htcp --enable-cache-digests --enable-default-err-language=Simplify_Chinese --enable-err-languages="Simplify_Chinese" --enable-poll --enable-linux-netfilter --disable-ident-lookups --enable-underscores --enable-auth="basic" --enable-basic-auth-helpers="NCSA" --enable-external-acl-helpers="ip_user" --enable-x-accelerator-vary

 

make && make install

 

 

4.设置squid.conf

 

cd

mv /etc/squid/squid.conf /etc/squid/squid.conf.bak

vi /etc/squid/squid.conf  #在按下i键

==============================/etc/squid/squid.conf=========================

coredump_dir /usr/local/squid/var/cache

===============================脚本结束================================

 

 

5.初始化cache目录和启动squid

 

cd

htpasswd -cb /etc/squid/passwd.sq proxy proxy

chmod 666 /etc/squid/passwd.sq

mkdir -p /usr/local/squid/var/cache

cd /usr/local/squid/var

chown -R nobody.nobody cache logs

squid -z

squid start

squid -k parse        #检查配置是否有错误,没有任何输出,证明配置基本是正确的!!!

squid -zX               #可以加一个X参数,看看初始化具体的项目.  

如果因为DNS无法启动squid,可以用下面的命令启动squid

squid -D

 

 

6.安装squid密码修改工具

 

修改/etc/httpd/conf/httpd.conf的内容,把"AddDefaultCharset" 设置成 GB2312,是WEB显示中文.

cd /usr/src

vi /var/www/html/index.html

 

============================/var/www/html/index.html=======================<a href="../cgi-bin/chpasswd.cgi">请单击这里修改您的用户密码</a>

===================================配置结束============================

 

wget -c http://jaist.dl.sourceforge.net/sourceforge/orsochpasswd/chpasswd-2.2.3.tar.gz

wget -c http://sarg.sourceforge.net/htoi.patch

tar -zxvf chpasswd-2.2.3.tar.gz

cd /usr/src/chpasswd-2.2.3

patch -p0 < ../htoi.patch

./configure --enable-language=Chinese --enable-cgidir=/var/www/cgi-bin

make && make install

vi /usr/local/etc/chpasswd/chpasswd.conf

 

=================/usr/local/etc/chpasswd/chpasswd.conf=========================

password_file /etc/squid/passwd.sq

=================================脚本结束==============================

 

 

7.防火墙设置及IP地址与MAC地址绑定

 

touch /usr /sbin/firewall

chmod u+x /usr/sbin/firewall

vi /usr/sbin/firewall

 

===============================/usr/sbin/firewall===========================

#!/bin/sh

 

UPLINK="eth0"

=================================脚本结束==============================

注:

建立IP地址与MAC地址对应关系表

touch /etc/ipmacfile

vi /etc/ipmacfile

ipmacfile文件格式

100.100.100.100 00:16:36:05:a6:54

100.100.100.101 00:16:36:05:a6:53

 

8.配置系统日志查看

cd

mkdir /var/www/html/logs

touch /usr/sbin/sqbak

chmod u+x /usr/sbin/sqbak

vi /etc/squid/index.html

 

===============================/etc/squid/index.html========================

<H1>客户端网络访问日志</H1>

<HR WIDTH="100%">

======================================================================

 

cp /etc/squid/index.html /var/www/html/logs/index.html

 

===============================/usr/sbin/sqbak============================

#!/bin/sh

logdir=/usr/local/squid/var/logs/

fl=access.log.0

bakpath=/logbak/

wwwpath=/var/www/html/logs/

sysdate=`date +%F`

day=`date +%d`

#lanip=`ifconfig eth1 | awk '/inet/{print $2}' | awk -F: '{print $2}' | grep -v ^$`

if [ "$day" = "01" ]

then

rm -f /var/www/html/logs/*

cp /etc/squid/index.html ${wwwpath}

fi

if [ -s "${logdir}""${fl}" ]

then

cd ${bakpath}

mv ${logdir}${fl} ${sysdate}.log

cat ${sysdate}.log | awk '{print NR " " substr($4,2) " " $3 " " $1 " " $7 " " $11 "/n"}' | awk '{printf "%-16s %-24s %-16s %-24s %-150s %-s/n",$1,$2,$3,$4,$5,$6}' > ${sysdate}.txt

tar -cvf ${sysdate}.tar ${sysdate}.txt

bzip2 -f ${sysdate}.tar

cp ${sysdate}.txt ${wwwpath}

echo "<br><a href=../logs/$sysdate.txt>[$sysdate]</a></br>" >> ${wwwpath}index.html

rm -f ${sysdate}.log ${sysdate}.txt

fi

======================================================================

 

crontab -u root -e

======================================================================

01 0 * * * /usr/sbin/squid -k rotate

15 0 * * * /usr/sbin/sqbak

======================================================================

 

 

9.设置启动项目

 

vi /etc/rc.d/rc.local

 

/usr/sbin/squid start

/sbin/firewall start

/usr/sbin/httpd start

10.批量生成用户名密码脚本

 

脚本一.

 

touch /usr/sbin/uuadd

chmod u+x /usr/sbin/uuadd

vi /usr/sbin/uuadd

 

=========================/usr/sbin/uuadd==================================

#!/bin/sh

#uuadd: batch add squid user.

#install step.

#chmod u+x uuadd

#./uuadd userfile

if [ $# -lt 1 ]

then

echo "Usage: Please set user's name file."

echo "Exmple: `basename $0` userfile."

echo "######userfile######"

echo "      username1"

echo "      username2"

echo "      username3"

echo "          ."

echo "          ."

echo "          ."

echo "      usernamen"

echo "#####################"

exit 1

fi

userfile=$1

uuadd=/usr/bin/htpasswd

while read line

do

$uuadd -b /etc/squid/passwd.sq $line $line

done < $userfile

=============================脚本结束==================================

注:

userfile文件内容的格式

username1

username2

    .

    .

    .

usernamen

脚本二.

 

touch /usr/sbin/upadd

chmod u+x /usr/sbin/upadd

vi /usr/sbin/upadd

 

===================================/usr/sbin/upadd========================

#!/bin/sh

#upadd: batch add squid user.

#install step.

#chmod u+x upadd

#./upadd userfile

if [ $# -lt 2 ]

then

echo "usage: $0 userfile"

exit 1

fi

userfile=$1

upadd=/usr/bin/htpasswd

while read username passwd

do

$upadd -b /etc/squid/passwd.sq $username $passwd

done < $userfile

=================================脚本结束==============================

注:

userfile文件内容的格式

username1 passwd1

username2 passwd2

 

 

请帮用户名设置为小写字母,批量生成的密码与用户名相同

 

单独更改用户密码:

htpasswd -b /etc/squid/passwd.sq 用户名 密码

 

 

 

 

 

 

 

 

 

 

Squid proxy server 使用FAQ

 

1.怎样添加新用户?

 

htpasswd -b /etc/squid/passwd.sq username password

 

说明:用htpasswd工具生成用户名为username密码为password的用户,保存在用户数据库/etc/squid/passwd.sq里.

 

2.怎样批量添加新用户?

 

1)      生成用户名和密码一样,然后用户自己更改

 

uuadd userfile

 

说明:用uuadd命令批量生成密码与用户名一样的初始用户,用此命令时请指定userfile文件,userfile文件格式如下,是多行单列的内容,请注意在初始化时,如果用户名里包含大写字母的,初始化时密码被初始成小写.

注:

userfile文件内容如下

username1

username2

    .  

    .                

Usernamen

 

最好是所有用户都用小写字母的用户名!!!

注意:

当下次在想批量添加用户时请指定你新的用户文件,因为如果你在还用以前的userfile文件的话,那么原来你的用户数据将被重新初始化.所以请每次批量添加玩用户时,把此文件删除!!!  

 

2)生成用户自己设的的用户名和密码

upadd userfile

 

说明:用upadd命令批量生成密码与用户名,用此命令时请指定userfile文件,userfile文件格式如下,是多行单列的内容,请注意在初始化时,如果用户名里包含大写字母的,初始化时密码被初始成小写.

注:

userfile文件内容的格式

username1 passwd1

username2 passwd2

3.用户初始化密码的更改和当用户想更换密码怎么办?

 

IE浏览器里输入http://服务器ip地址 点击"请单击这里修改您的代理服务器密码",看说明修改你的密码!!!

 

4.如果有用户忘记自己的密码怎么办?

 

请用第1个问题里方法给用户设置密码.

 

5.怎样查看系统日志?

 

请在IE浏览器里输入http://服务器ip/logs 能够查看一个月内的用户上网日志.

如果想查看全部的用户上网日志请用WINSCP连接上服务器,在目录/logbak目录下是以日期命名的日志.请你下载想看的日志到本地机器.然后用WINRAR解压后,用记事本即可查看日志了!

 

 

6.如果客户端上不去网怎么办?

1)

可以重新启动服务器 用命令 reboot或者shutdown -r now

 

2)  可能是硬盘空间不足,系统无法写入日志而导致代理服务器进程无法启动,请把/logbak目录下的日志文件拷贝到别的机器上,再把此目录里的文件删除,然后用reboot命令重新启动系统.

 

3)

也可能是突然断电,导致系统文件丢失,这中情况一般是不会发生,应为LINUX有自我修复功能.如果真的启动不起来,那么请用一张别的LINUX启动光盘启动,把系统里面的重要数据备份出来.重新安装系统吧!!!

要备份的文件包括:用户数据库文件/etc/squid/passwd.sq   系统日志文件/logbak目录下的所有文件和/usr/local/squid/var/logs/access.log文件 /etc/ipmacfile ip地址与mac地址绑定文件

 

4)网络不通,请检查网络状况

 

5)硬件系统出现故障,请检查内存,网卡等

 

6）ip和MAC的地址绑定问题
