FISCO BCOS (16) Multi-machine deployment and related operations

Multi-machine deployment usually refers to building a joint system between multiple computers or virtual machines to achieve distributed computing or service purposes. This improves system reliability, performance and scalability. To ensure that virtual machines can communicate with each other, you can use static IP or dynamic IP allocation. Next, we will take you step by step to build a blockchain system with two machines, one organization, eight nodes and one group.

报错：ssh: connect to host 192.168.251.17 port 22: Connection refused

1. First, you need to ensure that the two virtual machines can communicate.

Install the sshd service (both virtual machines need to perform this operation)

apt-get install openssh-server

Start sshd service

service sshd restart

A confirmation box will pop up, enter the virtual machine password.

2. Set the network connection of the two virtual machines to overseas connection mode

The premise is ready, let’s build a blockchain system with two machines, one organization, eight nodes and one group.

1. Check the IPs of the two virtual machines
