lingducloud-Tengxun Cloud Distributor: How to Correctly Connect Domain Name to Tengxun Cloud DNSPod and Perfect Open HTTPS for All Stations
In the Internet circle, there is a saying called "laymen look at the interface, professionals look at DNS".
As the "first hop" of the entire network, the speed and stability of DNS resolution directly determines the life and death of your website. Many teams spend a lot of budget to optimize servers and buy high-security CDN, but they just drop the chain on DNS resolution-slow resolution takes effect, overseas users visit Caton, and even suffer frequent DNS hijacking. To make matters worse, if HTTPS is not done well in the whole station, a red "unsafe" warning will pop up directly in the browser, and the users who are finally drained will be lost instantly.
In today's in-depth tutorial, I will not talk about textbook theories. I will directly start from the actual combat of the production environment and take you to connect the domain name to the so-called "resolution speed ceiling"
Tencent Cloud DNSPod
, and one step in place to open
Site-wide secure HTTPS protocol
.
Why did 1. choose Tencent Cloud DNSPod?
Before we start, we need to understand why we have to do this "domain name move".
The traditional domain name registrar's own resolution service often has the problems of few overseas nodes and slow resolution (sometimes it takes 24-48 hours). As the "big brother" in the domestic DNS field, Tencent Cloud DNSPod has the following hard-core advantages:
Global multi-line BGP coverage: BGP nodes with top-level computer rooms at home and abroad can intelligently match the optimal resolution path in seconds, whether in telecom, Unicom, mobile or overseas networks.
Second-level effective (TTL is extremely low): After modifying the analysis record, the global nodes can be updated synchronously in almost a few seconds, and temporary server switching during the big promotion period is no longer necessary.
High Anti-DDoS Anti-D: The node comes with strong DDoS protection capability to calmly deal with malicious attacks against the DNS layer.
2. Phase 1: Smooth migration of domain names to DNSPod (zero downtime migration)
Many people are afraid to change DNS, mainly because they are afraid that the website will interrupt access during the modification of DNS servers. In fact, as long as the standard mobile operation is followed, "zero downtime and no sense of migration" can be achieved ".
Step 1: Import parsing records in advance on DNSPod side
Log on to the Tengxun Cloud console, search and enter DNS to resolve DNSPod.
Click "Add a domain name" and enter your domain name (for example, yourdomain.com).
Core skill: Don't change the DNS of the domain name registrar at this time! First, in the DNSPod console, manually add all the analysis records (A records, CNAME, MX records, etc.) from the original registrar, or import them in batches through TXT/CSV files.
Step 2: Go to the original domain name registrar to modify the DNS server address
After ensuring that the records on this side of DNSPod are exactly the same as the original records, log on to the platform where you purchased the domain name (such as ariyun, GoDaddy, etc.) and find "modify DNS server (d
NS Servers) ", modify it to the exclusive DNS address of tengxun DNSPod:
f1g1ns1.dnspod.net
f1g1ns1.dnspod.com
Architect Tip: After modification, a global DNS refresh can take anywhere from a few hours to 24 hours. During this period, some users will visit the original DNS and some will visit the new DNS, but because the resolution records on both sides are exactly the same, your website will never interrupt access.
3. Phase 2: Apply for an SSL certificate and enable HTTPS for the entire site
After the domain name resolution migration is completed, the next step is to put on a secure "encryption cloak" for the website ".
Step 1: Apply for a free/paid SSL certificate in Tengxun Cloud
Search for SSL certificates (SSL Certificates) in the Tencent Cloud console.
For small and medium-sized enterprises or individual projects, tengxunyun provides a free DV certificate (usually provided by Let's Encrypt or DigiCert), which can be issued in a few minutes at the earliest. If security compliance requirements are extremely high, it is recommended to purchase a more advanced OV or EV team certificate.
Step 2: Use DNSPod to automatically complete DNS verification
When applying for a certificate, you need to prove that you are the owner of this domain name ".
Because our domain name has been connected to DNSPod, select in the authentication method
"DNS Automatic Verification"
. Tengxunyun will automatically add a TXT record for verification to your DNSPod record. Without manually copying and pasting, the certificate can be automatically issued within a few minutes, and the experience is extremely smooth.
Step 3: Deploy Certificate and Force HTTPS Jump
After the certificate is issued, download and deploy it to your Web server (Nginx / Apache / Tomcat) or Tengxun Cloud's load balancing (CLB) or EdgeOne. Take Nginx as an example, the standard "full-site HTTPS and automatic jump" configuration is as follows:
4. Pit Avoidance and Enterprise High Availability Closed Loop: Key Support at Non-technical Level
No matter how well the technical solution is deployed, it is only part of the enterprise IT operation. In the actual enterprise production environment, the stability and security of domain names are related to the digital lifeline of the entire company. If you are deploying this system for enterprises, the following compliant and cost-effective "non-technical channels" can help you avoid detours:
Avoid the risk of domain name and asset loss: the ownership and resolution control of domain names purchased by regular Tencent cloud accounts are the core assets of the company. Enterprises in progress
Purchase a Tencent Cloud account
When, be sure to go through official formal channels, and be sure to use the company's business license for enterprise real-name authentication. Don't try to save trouble and let technicians use their personal accounts to buy or trust on their behalf. Otherwise, once employees leave their jobs or disputes arise over their accounts, it is very easy for analysis to be maliciously tampered with and the website cannot be visited overnight.
Ask about catastrophic events.
Business discount and expert technical escort: docking tengxunyun agents for enterprises that need to manage hundreds of domain names in batches or purchase advanced enterprise DNS (supporting greater anti-d traffic and more intelligent resolution routes), it is recommended to contact compliant tengxunyun agents before purchasing. Price advantage: agents can apply to the official website direct orders can not get the big customer exclusive discount, package purchase discount, so that you can use the budget to buy the basic version directly to win the enterprise high distribution version. Technical blessing: the agent's own senior network engineer can help you design "overseas/domestic dual-route intelligent analysis" for complex scenarios such as cross-border e-commerce and overseas games, so as to accelerate overseas travel and domestic travel to domestic high defense and maximize performance.
Put an end to domain name expiration and arrears: make good use of tengxunyun to recharge DNS intelligent resolution (enterprise version) and advanced SSL certificates are usually paid on an annual basis. Many enterprises because of the financial reimbursement process cumbersome, foreign exchange control and other reasons, often forget to renew or insufficient account balance led to the analysis of the tragedy of the suspension. Through the agent to carry out tengxunyun recharge, enterprises can not only enjoy more flexible account period support and multi-currency compliance invoices, but also apply for advance emergency quota at an emergency juncture. Make sure that your domain name, resolution service, and SSL certificate are always renewed and stable during any traffic peaks or holidays.
5. epilogue
Connecting the domain name to tengxunyun DNSPod and opening the HTTPS of the whole station is not only the first step to improve the access speed of the website, but also the foundation for building a solid network security defense line. Through "zero downtime migration" to ensure business continuity, the use of "automatic verification" to speed up the issuance of certificates, combined with compliance and stable cloud ecological procurement channels (enterprise accounts, agents, on-behalf recharge services), the technical team can use the lowest business cost, build a set of fast and stable top-level network access architecture.
