Crawler Server: Distributed Collection Node Deployment and IP Management Solution

Without IP management in this day and age, crawlers are like running around naked

The friends who engage in data collection understand that the stand-alone crawler is now basically to send a person's head. Last week, an e-commerce price comparison brother and I complained, he wrote the script ran for two days by the target site blocked more than 20 IP. this scene is like wearing slippers to participate in the marathon - not yet started running is destined to fall head over heels.

Distributed node deployment is franklySplit up collection tasks into parts and distribute them to different workers. But if the workers (servers) all wear the same uniform (IP address), the supervisor (anti-crawling system) can recognize it at a glance. At this point, we need to prepare a different identity card for each worker, which is the meaning of the existence of proxy IP.

The trick to putting an invisibility cloak on a reptile

Ever seen a chameleon? Proxy IP is the equivalent of letting the server learn this camouflage. Here's an easy pitfall to step into: many people think that a large number of IPs is all that matters, but in factIP quality is the lifeblood.It's like buying fruit. It's like buying fruit, looking at a truckload of rotten apples is better than asking for a basket of fresh ones.

Take ipipgo, their residential IP is a real home network address, and the difference between the ordinary room IP is like the difference between live and frozen fish in the market. 90 million real residential IP resources, equivalent to the collection of each task are arranged for a different "home address", the website anti-climbing system can not feel the pattern. The website anti-climbing system simply can't feel the law.

Dynamic VS Static IP Selection Guide

Nodal Deployment of Seven Injuries Fist and Tai Chi Chuan

Ever seen a villain in a martial arts movie swinging his fists around? Many newbies deploy nodes like this: dozens of servers are opened on AWS, resulting in highly similar IP segments, and instead they are all over the place. The right way to do it isMix of different service providers + IP typesIt is like playing Tai Chi to emphasize the combination of rigidity and flexibility.

Here is a practical skill: the collection nodes are divided into three, six, nine and so on. The core task with ipipgo static residential IP to ensure stability, the edge of the task with dynamic IP to do cover. Just like the ancient war, the front elite troops with heavy armor, scouts wearing light clothing, each in its own way in order to improve the overall combat efficiency.

IP Management Four Minefields Self-Checklist

- Minefield 1: IP switching frequency like a jerk (too fast to trigger an anomaly)
- Minefield 2: All nodes crowded in the same time zone (too regular a pattern of behavior)
- Minefield 3: Impersonating a real person with a server room IP (easily recognized)
- Minefield 4: IP licenses won't play (wasted resources)

Here focuses on the authorization issue. ipipgo supports socks5/http(s) full protocol access, just like the different body types of workers to prepare a fitted uniform. In particular, their API dynamic extraction function, you can take IP resources on demand like a buffet, to avoid the end of the plate can not eat waste.

Quick questions and answers for veteran drivers

Q: What should I do if my IP is always blocked?
A: Check three points: 1. whether mixed residential / room IP 2. whether the switching frequency is reasonable 3. whether there is no imitation of a real person operating intervals. It is recommended to use ipipgo's dynamic residential IP pool, their automatic fusion mechanism can effectively avoid wind control.

Q: What can I do if the latency of transnational acquisition is too high?
A: That's why it's so advantageous to go with ipipgo. They have local relay nodes in more than 240 countries, which is equivalent to arranging a receiver at the doorstep of the target website. For example, if you grab the data of a U.S. website and use their node in Virginia directly, the delay can be controlled within 200ms.

Q：What should I do if I need to manage thousands of IPs at the same time?
A: Don't use the stone-age method of Excel! ipipgo's background has the function of grouping tags, which can be used to manage IPs just like a library classifies books. it supports multi-dimensional filtering according to country, operator, expiration date and so on, and it can set up automatic recycling rules, which is even more reliable than hiring ten administrators.

In the end, proxy IP management is just like stir-frying, the ingredients (IP quality), the fire (switching strategy), seasoning (authorization) which is not in place will affect the final taste. Choose a reliable "ingredients supplier" like ipipgo, at least to ensure that your data meal will not be made into dark cuisine. Remember, in this era where data is king, only the team that can play IP is qualified to play poker.
