This is undoubtedly DDos/CC Attacks or all kinds of malicious scanning, brute-force cracking, and malicious garbage crawlers can have very good interception effects, and hide the real server. IP In the case of DDos/CC Attacks can basically be ignored, what are the so-called CC Can be broken down CloudFlare It can only mean that I can't use it, there is no other explanation! Anyway, use CloudFlare Later, he was a young strongman who could not be beaten!

Note:at present CloudFlare Free version is only for the website DDos/CC Defensive, APP、 The game requires a paid version！

2、It has anti-collection and anti-theft chain

CloudFlare of【Server-side exclusion】and【HotLink】Just simply set it up on the website to prevent collection and anti-theft links, those common collections UA I haven't been there for more than a month Nginx I've seen it in the log! Cool! ! !

3、More thorough server performance optimization

With the help CloudFlare Officially announced nodes IP Cooperation based Linux The kernel's firewall application restrictions are only CloudFlare node IP Only then can you return to the source server to request 443 and 80 Ports can not only greatly enhance the security of the server, but also effectively exert the server hardware performance, removing all illegal source requests to reduce the risk of server load soaring. if CloudFlare If the cache time is long, it can even make the server not allow the large number of concurrent requests. CPU、 The load of memory, etc. is soaring.

Let's talk about the bad things

1、Domestic browsing speed will have regional differences and different effects

Regarding this aspect, Mingyue’s actual test is that the mobile network speed is the best, followed by China Unicom, the telecom network, and the mobile phone and PC There will be a slight difference on it. The mobile phone network where Mingyue is located has the best effect, and the speed is turned on in seconds. There are delays and stutters in China Unicom and Telecom mobile phone networks, but they are both within an acceptable range. Special statement: Mingyue's tests are not available CloudFlare of Anycast IP Preferred, completely random CloudFlare node IP Effect. So it's called CloudFlare The impact on the speed of domestic visits is only in some areas. For example, some provinces with strict control in areas such as rampant telegram fraud and cybercrime are relatively large, and most provinces and cities have very little impact.

Of course, some visitors also reported CloudFlare of IP Mingyue has not encountered any nodes because of the content of the black industry website. Theoretically, Mingyue has not encountered it. CloudFlare of IP The node library is not small, this kind of thing is inevitable, there is Anycast With the support of technology, it can usually return to normal soon.

To sum up, Mingyue recommends that domestic stations use CloudFlare If it is only for overseas routes, domestic routes are still used CDN The best. As for overseas websites, there will generally be no problem to pay attention to harmonious content!

2、Need to adjust customization frequently WAF rule

CloudFlare of WAF The rules are quite flexible, free and powerful, so this is also difficult for many novices to use CloudFlare The main reason is, like those who shouted CloudFlare Can be the same DDos/CC The rat shit that was beaten to death belongs to this category. I don’t know where to pretend, thirteen o’clock!

It's because CloudFlare of WAF Too powerful, so you need to adjust it regularly according to the situation of your site WAF The rules are mainly to reduce misinterception, especially most domestic search engines have not publicly search crawlers. IP The library requires frequent analysis Nginx/Apache Logs and CloudFlare inside【Security】——【event】to adjust your own records WAF Rules, basically CloudFlare 5 items available in the free version WAF There are no end to the rules.

Note: Considering that each site has its own different situations, Mingyue does not recommend that you copy it. WAF Otherwise, the rules will cause many unnecessary faults and errors, and it is best to use them as reference!

Summarize

About site usage CloudFlare The benefits and disadvantages are summarized at this time. Although there are good and bad, considering that it is free to get a job and can defend against it. DDos/CC Attacks invade, and from then on, say goodbye to the embarrassment of causing server black holes and blocking due to being attacked. CloudFlare It's definitely worth using it, especially when it's affected DDos/CC When intrusion, although there are also domestic WAF Free CDN ， But Mingyue experienced it all and found that almost all of them were castrated versions, like CloudFlare So complete and free CDN I haven't encountered it yet! It’s a pity!
