Proxy server construction guide: self-built proxy server complete tutorial

Hands-on with a proxy server.

There are always people asking whether it is particularly difficult to build a proxy server, in fact, it is almost the same as building blocks. Today, let's nag some real, with the most coarse words to understand this matter. First of all, let's make it clear that the main purpose of building your own server is to do data collection, multi-account management and these serious purposes, don't organize those that have nothing.

Why do you have to do it yourself?

There are so many agent service providers in the market, like us.ipipgoSuch professionals are not vegetarians either. But some of the old iron love to do it themselves, may feel more at ease, or to get some special operation. For example, you want to test a software in different areas of the operation, or need to fix the IP of a certain location for a long time, this time to build their own really more flexible.

Don't be sloppy with your preparations.

First of all, the whole reliable server, it is recommended to choose the machine room close to the target area. For example, if you want to get a U.S. IP, the whole U.S. West VPS. memory does not need to be too large, 1GB is enough to make, focusing on the quality of the network. The system is recommended to use Ubuntu, friendly to newbies.

Here's a quick aside. If it's too much trouble, you can just go withCloud servers for ipipgo, their machines come with the proxy environment pre-installed, so you don't have to fiddle with it yourself.

Hands-on building process

Take HTTP proxy for example, let's use Squid, an old school tool:

sudo apt-get update
sudo apt-get install squid
sudo nano /etc/squid/squid.conf

locatehttp_portChange it to the desired port, for example 3128. then add two lines to the configuration file:

acl localnet src your IP address
http_access allow localnet

Save and restart the service:

sudo systemctl restart squid

At this point, you can set the proxy server address and port in your local browser and it will work. If you want to use socks5, you can use Dante-server, the steps are similar.

Guide to avoiding the pit

Seen too many people planted in these places:

1. Fireproof no open ports - remember to release them in the server security group
2. Configuration file formatting errors - check for semicolons and spaces a few more times
3. IP Blocked by Target Website - Time to Consider Professional Services

QA session

Q: What can I do about the slow speed of self-built agents?
A: First look at the server bandwidth, and then check the configuration to see if there is a speed limit. If the physical distance is too far, change the server room, or directly on theipipgo's cross-border lineThe

Q: What should I do if my IP is blocked?
A: If you build your own, you can only change servers, which is time-consuming and expensive. It is recommended to useDynamic residential IP for ipipgoThe automatic switching doesn't hurt.

Saving Program Recommendations

It's fine to build your own for fun, but for real work you need a pro. For exampleipipgoThese packages:

The best smell in their house is supportsocks5 direct connectionIf you want to get the IP address, you don't need to install the software, you just need to fill in the IP address directly into the program, and it's also easy to extract the API, so let's give you a sample code:

import requests

proxy = {
    'http': 'http://username:password@gateway.ipipgo.com:端口',
    'https': 'http://username:password@gateway.ipipgo.com:端口'
}

response = requests.get('destination URL', proxies=proxy)

Finally, to tell the truth, self-built this thing, short-term use of the short-term use, long-term use or professional services cost-effective. Especially when you need high-quality IPs, you can't really play with a professional service provider on your own server.
