Squid代理缓存squid –k rec //重新加载配置文件

透明缓存原理图:
配置squid服务器内网卡ens33,外网卡ens37
内:192.168.100.10
外:12.0.0.1 //无网关
web服务器:12.0.0.100 网关12.0.0.1
客户:192.168.100.7 网关192.168.100.10
Squid服务器配置:
路由转发功能开启:
cd /proc/sys/net/ipv4
将 echo 1 > ip_forward 值改为1
[root@localhost ipv4]# vi /etc/squid.conf
将http_port 3128 改为http_port 192.168.100.10:3128 transparent
[root@localhost ipv4]# service squid restart
[root@localhost ipv4]# netstat -anpt | grep 3128
tcp 0 0 192.168.100.10:3128 0.0.0.0: LISTEN 2627/(squid-1)

配置web httpd服务:
这里记得修改网卡,vmnet2
Vm虚拟机网卡配置:
Client端widows7网卡配置如下:
Client端网页访问12.0.0.100
查看squid服务器日志:cat /usr/local/squid/var/logs/access_log
配置sarg日志分析软件--用来分析squid服务的日志
注意:需要在代理服务器上安装WWW服务器
[root@localhost sarg-2.3.11]# yum install httpd gd -y
[root@localhost sarg-2.3.11]# systemctl restart httpd
[root@localhost sarg-2.3.11]# tar xf sarg-2.3.11.tar.gz
[root@localhost sarg-2.3.11]# cd sarg-2.3.11
[root@localhost sarg-2.3.11]# ./configure --prefix=/usr/local/sarg --sysconfdir=/etc/sarg --enable-extraprotection
[root@localhost sarg-2.3.11]# make && make install
[root@localhost sarg-2.3.11]# vi /etc/sarg/sarg.conf 去掉#号修改的地方修改
7 access_log /usr/local/squid/var/logs/access.log //squid的访问日志位置
25 title "Squid User Access Reports" //网页标题
120 output_dir /var/www/html/squid-reports //分析报告的存放位置
178 user_ip no //不使用IP代替用户ID
184 topuser_sort_field BYTES reverse //升序排列
190 user_sort_field BYTES reverse
206 exclude_hosts /usr/local/sarg/noreport //设置不生成报告的主机
257 overwrite_report no
289 mail_utility mailx //指定发邮件命令

633 www_document_root /var/www/html //网页根目录
[root@localhost sarg-2.3.11]# touch /usr/local/sarg/noreport //建立不生成报告的主机列表文件
[root@localhost sarg-2.3.11]# ln -s /usr/local/sarg/bin/sarg /usr/local/bin/
[root@localhost sarg-2.3.11]# sarg //访问几次会有记录
SARG: Records in file: 627, reading: 100.00%
SARG: Successful report generated on /var/www/html/squid-reports/2019Jan10-2019Jan10
访问:http://192.168.100.10/squid-reports/ //访问日志页
配置反向代理:当外网主机访问缓存服务器外网口址时,实现内网调度,同时可以缓存提速,保护内网服务器
[root@localhost ~]# vi /etc/squid.conf
http_port 192.168.100.10:80 accel vhost vport
cache_peer 192.168.100.20 parent 80 0 no-query originserver round-robin max_conn=30 weight=1 name=web1
cache_peer 192.168.100.30 parent 80 0 no-query originserver round-robin max_conn=30 weight=1 name=web2
cache_peer_domain web1 web2 www.aa.com //添加
*修改真机host文件
192.168.100.20 www.aa.com
192.168.100.30 www.aa.com
[root@localhost ~]# service squid restart
[root@localhost ~]# netstat -anpt | grep squid
tcp 0 0 192.168.100.10:80 0.0.0.0: LISTEN 980/(squid-1)
在客户端测试效果:www.aa.com
**注意internet选项打开代理选项
自动轮询,反向代理成功!
