Most people do not understand the knowledge points of this article "how to deploy Neo private chain", so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "how to deploy Neo private chain" article.

Configure a virtual machine

The deployment of the NEO private chain requires at least four servers to reach a consensus, with each server corresponding to a consensus node. Pay-per-view virtual machines (all window server machines) can be bought on Aliyun.

Record the intranet IP addresses of the four machines, which you will use later.

172.xxx.xxx.142 port

If you want external programs to access the node's API, you need to open firewall ports: 10331-10334, 20331-20334

Aliyun's vpc does not need to be set if it is in a security group. All entrances can also be opened through the security group.

Install Runtime

Operation environment

.NET Core Runtime is required to run the NEO node, and version 1.0.1 or above is required.

Installation method under Windows system

It is very convenient to install .NET Core under the Windows system, so you can download and run it directly.

NOTE

Windows may also need to install Microsoft Visual C++ 2015 Redistributable Update 3 (https://www.microsoft.com/en-us/download/details.aspx?id=53840)), otherwise Neo-CLI cannot be started later.

Create a wallet

Create a wallet database on each of the four machines, and the database files will be generated under the neo-cli directory by default

Create wallet wallet.json

Database files with db3 suffixes are no longer supported

If you have previously opened cli, delete the files in the chain directory so that the block chain height starts at 1.

Intercept one of the prints, which is convenient for debugging later.
