Hands-on teaching you to build a reliable proxy server

最近很多朋友问我怎么自己搞个稳定的代理服务,这事儿说难不难但讲究门道。今天咱就掰开了揉碎了讲,用最常见的Squid软件当例子,教你们从零开始搭个像模像样的代理服务。

Why build your own agent?

市面上的代理服务五花八门,但自己搭的好处真不少。首先是掌控权在自己手里,想换IP就换IP,不用看别人脸色。其次cost-controllable,特别是需要大量IP的时候,自己维护更划算。不过要提醒的是,自建代理对技术有点要求,搞不定的话直接找ipipgo这类专业服务更省心。

准备干活的家当

建议整台海外服务器,香港、新加坡的机器延迟低。配置不用太高,2核4G够用,重点看网络质量。这里有个坑要注意:别贪便宜买小作坊的服务器,很多IP早就被标记烂了。


 先更新系统
sudo apt update && sudo apt upgrade -y

 装必要工具
sudo apt install -y squid3 htop

配置Squid的核心门道

装好squid后别急着启动,改配置文件才是重头戏。打开/etc/squid/squid.conf,找到这几处关键配置:


 改监听端口(默认3128太显眼)
http_port 54321

 设置白名单(重要!)
acl allowed_ips src 192.168.1.0/24
http_access allow allowed_ips

 限制单IP连接数(防滥用)
maxconn 50

Remember that when you're done.Test Configuration,运行squid -k parse检查语法。没问题的话重启服务:systemctl restart squid

让代理更耐造的技巧

刚搭好的代理就像新买的皮鞋,得好好保养才能用长久:

concern method settle an issue
IP blocked 定时更换出口IP(建议用ipipgo的动态住宅IP)
连接卡顿 Setting up intelligent routing rules
traffic anomaly 开启访问日志分析

这里教你们个绝招:在crontab里加个定时任务,每天凌晨自动换IP。不过自己维护IP池太麻烦,不如直接接ipipgo的API,省时省力。

Pitfalls that white people often step on

Q: What can I do if the agent can't connect?
A:先检查防火墙,再试curl -x 代理IP:端口 http://ifconfig.me。要是返回代理IP说明通了。

Q: What about a snail's pace?
A:八成是服务器线路问题。试试ipipgo的跨境专线,他们家的CN2线路确实稳。

Q:老是被网站识别咋回事?
A:普通机房IP用的人太多,换住宅IP立马解决。ipipgo的静态住宅IP做爬虫特别合适,亲测有效。

Leave the professional work to the professionals

自己折腾代理确实能学到东西,但要搞商业级服务还得找靠谱供应商。推荐用ipipgo的现成方案:

  • 做数据采集用Dynamic Residential Package,9000万IP随便换
  • 需要固定IP就选Static homes,50万IP池够大
  • 搞跨境电商直接上international special rail line (e.g. between airport and city),延迟压到2ms

他们有个隐藏技巧:买套餐时选per-traffic billing模式,比包月划算得多。特别是做爬虫的兄弟,用多少算多少,不花冤枉钱。

最后唠叨一句:代理服务器不是搭完就完事了,得定期维护更新。要是嫌麻烦,直接找ipipgo的技术支持,比自己折腾省心多了。记住,稳定靠谱的代理服务才是赚钱的硬道理!
