squid代理http和https方式上网的操作记录
squid代理http和https方式上网的操作记录
8月前
需求说明: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)
操作思路: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。(当然也可以将下面B的http和C机器的https代理环境放在一台机器上部署)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 ]
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 []:[email protected] #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/[email protected]
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
[rootnew-test1 ~]# /etc/init.d/iptables stop -
[rootnew-test1 ~]# cd /usr/local/src/ -
[rootnew-test1 src]# pwd -
/usr/local/src
官网下载:http://www.stunnel.org/downloads.html
百度云盘下载:https://pan.baidu.com/s/1JXqfB7yc6H2GY9qtBVO4iw 提取密码:4kt8
[rootnew-test1 ~]#yum install -y openssl openssl-devel gcc -
[rootnew-test1 src]# ls -
stunnel-5.45.tar.gz
[rootnew-test1 src]# tar -zvxf stunnel-5.45.tar.gz -
[rootnew-test1 src]# ls -
stunnel-5.45 stunnel-5.45.tar.gz
[rootnew-test1 src]# cd stunnel-5.45 -
[rootnew-test1 stunnel-5.45]# ./configure -
[rootnew-test1 stunnel-5.45]# make && make install -
安装完成后,配置stunnel.conf
[rootnew-test1 stunnel-5.45]# cd /usr/local/etc/stunnel/ -
[rootnew-test1 stunnel]# ls -
stunnel.conf-sample
[rootnew-test1 stunnel]# cp stunnel.conf-sample stunnel.conf -
[rootnew-test1 stunnel]# ls -
stunnel.conf stunnel.conf-sample
[rootnew-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
[rootnew-test1 stunnel]# /usr/local/bin/stunnel /usr/local/etc/stunnel/stunnel.conf -
[rootnew-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
[rootnew-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
[rootnew-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)
[rootnew-test1 stunnel]# source /etc/profile #配置生效 -
4)测试:
[rootnew-test1 stunnel]# curl http://www.baidu.com #访问80端口ok -
[rootnew-test1 stunnel]# curl https://www.xqshijie.com #访问443端口ok -
[rootnew-test1 stunnel]# yum list #yum可以正常使用 -
[rootnew-test1 stunnel]# wget http://www.autohome.com.cn/3442 #wget正常下载 -
+++++++++++++++++++++++++++++++++++++++++++++++++++
如果客户机是ubuntu系统,则安装配置stunnel记录如下:
root@kevin-KVM:~# apt-get install stunnel4
root@kevin-KVM:~# cd /etc/stunnel/
root@kevin-KVM:/etc/stunnel# ls
README
root@kevin-KVM:/etc/stunnel# vim stunnel.conf #手动创建该配置文件
client = yes
[https]
accept = 127.0.0.1:8088
connect = 192.168.1.8:443
root@kevin-KVM:/etc/stunnel# vim /etc/default/stunnel4
......
ENABLED=1 #默认为0
=========================================================
注意:
上面的ENABLED一定要修改为1,否则启动stunne服务时会失败,通过status查看报错为:
5月 27 00:45:56 kevin-KVM systemd[1]: Starting LSB: Start or stop stunnel 4.x (SSL tunnel for network daemons)...
5月 27 00:45:56 kevin-KVM stunnel4[23356]: SSL tunnels disabled, see /etc/default/stunnel4
5月 27 00:45:56 kevin-KVM systemd[1]: Started LSB: Start or stop stunnel 4.x (SSL tunnel for network daemons).
=========================================================
接着启动stunne服务
root@kevin-KVM:~# /etc/init.d/stunnel4 start
root@kevin-KVM:~# /etc/init.d/stunnel4 restart
root@kevin-KVM:/etc/stunnel# lsof -i:8088
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
stunnel4 23625 root 7u IPv4 138476 0t0 TCP localhost:omniorb (LISTEN)
然后进行代理的环境变量配置
root@kevin-KVM:~# cat /etc/profile
......
export http_proxy=http://192.168.1.8:3128
export https_proxy=http://127.0.0.1:8088
root@kevin-KVM:~# source /etc/profile
测试上网:
root@kevin-KVM:~# curl http://www.baidu.com
root@kevin-KVM:~# curl https://www.baidu.com
