Virtual machine came into being. Compared with traditional host, virtual machine has more coverage, fast response, elastic scalability on demand and easy management. However, many users do not know how to create it. The following will describe how Tencent cloud creates a cloud server.
How to apply for free virtual machine?
1. First search in the search engine: Tencent cloud, enter the Tencent cloud official website, as shown in the figure below, and click "experience now".
2. You need to log in before applying for free. Click the login button in the upper right corner of the page to open the login interface. It is recommended to log in with QQ number, preferably the QQ number with real name authentication. In this way, the real name authentication can be exempted.
3. After logging in, click the free package on the home page. Many ECS CVMs can be seen on the slide page. If the button is gray, it means that it has been robbed today. Come back tomorrow. You can apply under normal circumstances.
4. After clicking a virtual machine, open "start on the machine".
5. The second step requires real name authentication. If QQ has real name authentication, it is not necessary. Then the user will enter the IP allocation state and wait a moment.
6. After that, we can enter the virtual machine.
Supplement: server introduction
Servers, also known as servers, are devices that provide computing services. Since the server needs to respond to service requests and process them, generally speaking, the server should have the ability to undertake services and ensure services.
The composition of the server includes processor, hard disk, memory, system bus, etc., which is similar to the general computer architecture. However, due to the need to provide highly reliable services, it requires high processing capacity, stability, reliability, security, scalability, manageability and so on.
In the network environment, according to the different types of services provided by the server, it is divided into file server, database server, application server, web server, etc.

1. System blue screen, frequent crash, restart, slow response
The of the server is very similar to our ordinary computer, whether it is hardware structure or running system. Therefore, just like our computers, they may be infected with viruses, crash, blue screen, restart and other failures due to system vulnerabilities, software conflicts and hardware failures, and slow response due to too much garbage cache information.
2. The remote desktop connection exceeds the maximum number of connections
Since the server allows 2 connections by default, if you forget to log off after logging in and directly close the remote desktop, the server recognizes that the login is still on the server side. In this case, the most common is to restart the server. However, if it is the peak period, the loss caused by restarting the server is obvious. At this time, you can use the mstsc / console command to forcibly log in. Open the "run" box and type "mstsc / V: xxx.xxx.xxx.xxx (server IP) / console" to forcibly log in to the remote desktop.
3. How to clean up files that cannot be deleted
In this case, it may be that the file is still running. You can restart and delete it, or run CMD, enter the name of the folder arrtib-a-s-h-r you want to delete, and finally enter the name of the folder del wants to delete. It cannot be recovered after running this command. Please use it with caution.
4. Hidden trouble of system port
For the server, the first thing is to ensure stability and security. Therefore, we only need to ensure the most basic functions of the server, just like the sound card is prohibited by default. We don't need too many functions and port support. For example, some unnecessary and high-risk ports can be blocked. For some necessary and risky ports, such as ports 3389 and 80, we can set them as non-special secret ports by modifying the registry, so that the security hidden dangers of server ports no longer exist.
