Key points of domain name registration at present, the leading domain name service providers are Ali (Wanwang) and Tencent (Xin.com? ), Baidu, etc., recommend Ali, because many people's domain names are registered in Ali (a domain name can be queried through the Ministry of Industry and Information Technology) can only buy first-level domain names, second-level, third-level domain names cannot be purchased, second-level domain names, etc., after the purchase of first-level domain names, domain names are generally purchased on an annual basis in the interface of the service provider, which is cheaper in the first year and more expensive to renew later, com and cn are more expensive (about 50 yuan) New top and club cheaper (about 20) domain names must be authenticated by real name after purchase, individual domain name must be × × ×, enterprise domain name must be licensed, otherwise after domain name management key points can not be used for a period of time, after purchasing domain name, you can configure the ip of the first-level domain name in "Domain name Resolution" or configure another ip for the second-level domain name. Different second-level domain names can be configured with different ip or the same ip. It seems that you can also configure the ip+ port. However, the (unverified) dns servers that need to be put on record are generally available by default and will be displayed automatically. They do not need to be configured by themselves (Tencent needs to manually refresh them, Ali automatically). It seems that the main points for filing must be put on record, otherwise they will not be available after a period of time (at present, I have used it for a month, I can still use it, but not for the record) for filing individuals fill in personal information and enterprises fill in enterprise information. You also have to take photos according to the background. You need to put on record with the service provider of the host, rather than with the service provider of the domain name. The issuer of the certificate that has tried the key points of the SSL certificate is Symantec (known as No.1, in fact, the root certificate of digicert, because chrome has announced that it will not recognize its root certificate and has been acquired by digicert), honesty Asia and other integrity Asia have provided free certificates in Tencent Cloud. Ali Yun's is Symantec's free certificate. Show green https and green lock, but the data is not encrypted and you can only bind a single domain name. Other certificates generally cost several thousand yuan a year. Depending on whether you want to bind multiple first-level domain names or bind multiple second-level domain names under the same first-level domain name, the more you bind, the more expensive, the more expensive, the more secure you should be encrypted. After buying certificates ranging from 2000 yuan to 10000 yuan, browsers no longer prompt. Calling directly with the code is also successful (using the self-signed certificate browser will indicate that it is not safe, and the code call will also report an error) after buying the certificate, Ali Tencent will teach you on the web page how to configure on nginx, etc.
