squid代理http和https方式上网的操作记录

时间:2022-04-23
本文章向大家介绍squid代理http和https方式上网的操作记录,主要内容包括其使用实例、应用技巧、基本知识点总结和需要注意事项,具有一定的参考价值,需要的朋友可以参考一下。

背景: 公司IDC机房有一台服务器A,只有内网环境:192.168.1.150 现在需要让这台服务器能对外访问,能正常访问http和https请求(即80端口和443端口)

思路: 在IDC机房里另找其他两台有公网环境的服务器B(58.68.250.8/192.168.1.8)和服务器C(58.68.250.5/192.168.1.5),且这两台服务器和内网环境的服务器A能相互ping通。 其中: 在服务器B上部署squid的http代理,让服务器C通过它的squid代理上网,能成功访问http 在服务器C上部署squid的https代理,让服务器C通过它的squid代理上网,能成功访问https   [需要在客户端安装stunnel ]

下面开始记录这一需求的操作记录: --------------------------------------------------------------------------------------------------------------------------- 一、服务器B上的操作记录(http代理)

1)安装squid yum命令直接在线安装squid [root@openstack ~]# yum install -y gcc openssl openssl-devel #依赖软件要先提前安装 [root@openstack ~]# yum install squid

安装完成后,修改squid.conf 文件中的内容,修改之前可以先备份该文件 [root@openstack ~]# cd /etc/squid/ [root@openstack squid]# cp squid.conf squid.conf_bak [root@openstack squid]# vim squid.conf http_access allow all                                                   #修改deny为allow http_port 192.168.1.8:3128 cache_dir ufs /var/spool/squid 100 16 256                    #打开这个注释,保证/var/spool/squid这个缓存目录存在

2)启动squid,启动前进行测试和初始化 [root@openstack squid]# squid -k parse                    #测试 2016/08/09 13:35:04| Processing Configuration File: /etc/squid/squid.conf (depth 0) 2016/08/09 13:35:04| Processing: acl manager proto cache_object .............. .............. 2016/08/09 13:35:04| Processing: refresh_pattern . 0 20% 4320 2016/08/09 13:35:04| Initializing https proxy context

[root@openstack squid]# squid -z                            #初始化 2016/08/09 13:35:12| Creating Swap Directories

[root@openstack squid]# /etc/init.d/squid start Starting squid: . [ OK ]

如果开启了防火墙iptables规则,则还需要在/etc/sysconfig/iptables里添加下面一行,即允许3128端口访问: -A INPUT -s 192.168.1.0/24 -p tcp -m state --state NEW -m tcp --dport 3128 -j ACCEPT

然后重启iptables服务 [root@openstack squid]# /etc/init.d/iptables restart

--------------------------------------------------------------------------------------------------------------------------- 二、服务器C上的的操作记录(https代理)

1)安装squid yum命令直接在线安装squid [root@openstack ~]# yum install -y gcc openssl openssl-devel #依赖软件要先提前安装 [root@openstack ~]# yum install squid [root@openstack ~]# cd /etc/squid/ [root@openstack squid]# cp squid.conf squid.conf_bak

2)现在开始生成加密代理证书: [root@bastion-IDC squid]# pwd /etc/squid [root@bastion-IDC squid]# openssl req -new > lidongbest5.csr Generating a 2048 bit RSA private key ..........................................................................+++ .........................................................................................................+++ writing new private key to 'privkey.pem' Enter PEM pass phrase:                                                                   #输入密码,后面会用到,比如这里输入123456 Verifying - Enter PEM pass phrase: ----- You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [XX]:cn                                                  #国家 State or Province Name (full name) []:beijing                                       #省份 Locality Name (eg, city) [Default City]:beijing                                      #地区名字 Organization Name (eg, company) [Default Company Ltd]:huanqiu        #公司名 Organizational Unit Name (eg, section) []:Technology                            #部门 Common Name (eg, your name or your server's hostname) []:huanqiu    #CA主机名 Email Address []:wangshibo@xqshijie.cn                                              #邮箱

Please enter the following 'extra' attributes to be sent with your certificate request A challenge password []:123456                                                         #证书请求密钥,CA读取证书的时候需要输入密码 An optional company name []:huanqiu                                                #-公司名称,CA读取证书的时候需要输入名称

[root@bastion-IDC squid]# openssl rsa -in privkey.pem -out lidongbest5.key Enter pass phrase for privkey.pem:                                                     #输入上面设置的密码123456 writing RSA key

[root@bastion-IDC squid]# openssl x509 -in lidongbest5.csr -out lidongbest5.crt -req -signkey lidongbest5.key -days 3650 Signature ok subject=/C=cn/ST=beijing/L=beijing/O=huanqiu/OU=Technology/CN=huanqiu/emailAddress=wangshibo@xqshijie.cn Getting Private key

修改squid.conf配置文件 [root@bastion-IDC squid]# vim squid.conf http_access allow all #deny修改为allow #http_port 3128                                                                    #注释掉 https_port 192.168.1.5:443 cert=/etc/squid/lidongbest5.crt key=/etc/squid/lidongbest5.key            #添加这一行 cache_dir ufs /var/spool/squid 100 16 256                             #打开这个注释,保证/var/spool/squid这个缓存目录存在

3)重启squid服务 [root@bastion-IDC squid]# squid -k parse [root@bastion-IDC squid]# squid -z [root@bastion-IDC squid]# squid reload [root@bastion-IDC squid]# /etc/init.d/squid restart

如果开启了防火墙iptables规则,则还需要在/etc/sysconfig/iptables里添加下面一行,即允许443端口访问: -A INPUT -s 192.168.1.0/24 -p tcp -m state --state NEW -m tcp --dport 443 -j ACCEPT

然后重启iptables服务 [root@bastion-IDC squid]# /etc/init.d/iptables restart

--------------------------------------------------------------------------------------------------------------------------- 三、服务器A(即客户端)上的操作记录

1)安装配置stunnel

关闭客户端的iptables防火墙 [root@dev-new-test1 ~]# /etc/init.d/iptables stop

[root@dev-new-test1 ~]# cd /usr/local/src/ [root@dev-new-test1 src]# pwd /usr/local/src

下载:http://pan.baidu.com/s/1boDDwrP (提取秘钥:pc7p) [root@dev-new-test1 ~]#yum install -y openssl openssl-devel gcc

[root@dev-new-test1 src]# ls stunnel-5.35.tar.gz [root@dev-new-test1 src]# tar -zvxf stunnel-5.35.tar.gz [root@dev-new-test1 src]# ls stunnel-5.35 stunnel-5.35.tar.gz [root@dev-new-test1 src]# cd stunnel-5.35 [root@dev-new-test1 stunnel-5.35]# ./configure [root@dev-new-test1 stunnel-5.35]# make && make install

安装完成后,配置stunnel.conf [root@dev-new-test1 stunnel-5.35]# cd /usr/local/etc/stunnel/ [root@dev-new-test1 stunnel]# ls stunnel.conf-sample [root@dev-new-test1 stunnel]# cp stunnel.conf-sample stunnel.conf [root@dev-new-test1 stunnel]# ls stunnel.conf stunnel.conf-sample [root@dev-new-test1 stunnel]# cat stunnel.conf              #把原来内容清空,写入: client = yes [https] accept = 127.0.0.1:8088 connect = 192.168.1.5:443                               #运行本机stunnel端口8088连接squid服务端192.168.1.5的443端口,然后在/etc/profile里配置本机8088端口代理(如下)

2)启动stunnel服务 [root@dev-new-test1 stunnel]# /usr/local/bin/stunnel /usr/local/etc/stunnel/stunnel.conf [root@dev-new-test1 stunnel]# ps -ef|grep stunnel root 20281 1 0 02:23 ? 00:00:00 /usr/local/bin/stunnel /usr/local/etc/stunnel/stunnel.conf root 20283 13002 0 02:23 pts/0 00:00:00 grep --color stunnel [root@dev-new-test1 stunnel]# lsof -i:8088 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME stunnel 20281 root 7u IPv4 745475 0t0 TCP localhost:radan-http (LISTEN)

3)配置/etc/profile系统环境变量 底部添加下面两行 [root@dev-new-test1 stunnel]# vim /etc/profile ............... export http_proxy=http://192.168.1.8:3128                          #这个是通过服务端A机器的3128端口的squid上网(http代理) export https_proxy=http://127.0.0.1:8088                            #这个是通过服务端B机器的443端口的squid上网(https代理)

[root@dev-new-test1 stunnel]# source /etc/profile                   #配置生效

4)测试: [root@dev-new-test1 stunnel]# curl http://www.baidu.com                           #访问80端口ok [root@dev-new-test1 stunnel]# curl https://www.xqshijie.com                      #访问443端口ok [root@dev-new-test1 stunnel]# yum list                                                     #yum可以正常使用 [root@dev-new-test1 stunnel]# wget http://www.autohome.com.cn/3442      #wget正常下载
