Server environment setup
(1) If you want to do good things, you must first sharpen your tools. To develop an independent site, you first need a stable and sustainable server environment. 2018.3.15: Purchase Alibaba Cloud Server.
The road to buying Alibaba Cloud is particularly bumpy. First of all, I don't know much about cloud servers, I don't know the industry situation, and I have no purchase experience, so I spent a lot of time deciding which server to buy this time, and finally chose Alibaba Cloud server.
For those who are new to the road, the first thing to know is that the upper right corner of Alibaba's official website provides a lot of help documents. These documents can be found and solved when you encounter difficulties. If you don't understand, you can open some documents to browse. Look, know where to find solutions to problems encountered.
When purchasing a server, you will be asked to create an instance. This instance is actually an operating system. After selecting an instance and related configurations, you can generate an instance by paying for it. There is a console in the upper right corner of Alibaba's official website, through which you can view the products owned by our current users, etc.
Open the console to display the relevant products of this user. In the recently used product column, you can see the word cloud server ECS. After clicking, you can enter the details of the server, and you can view the specific situation of the current server. As shown below
In the figure, you can see that a cloud server is running. Click to enter the server to pop up the instance list, and you can see the operating system (ie instance) installed on the current server.
Click on the remote connection to jump to the connection server page. When you enter the instance connection for the first time, the default instance connection password will pop up. If this password is not changed, it will always be the same. You can use this password to connect to this instance. If you forget it, you can also reset it to obtain a new connection code.
If the server system is a Linux server, you need to log in again. It should be noted here that the login account of the Linux system is the default user root. If the login password is not set, you need to reset the login password and then restart the server. The system login password and the instance connection password are not the same thing. Do not understand that mistakes are wasted time (don't ask how I know that! 
). After entering your username and password, you can log in.
(2) After logging in to the remote server, you need to perform a series of basic configurations on the server.
