Teach you step by step how to use the build_chain.sh script to deploy a single group four-node blockchain network locally

introduction

Just get started and you're done. It is recommended that you analyze the structure of the nodes directory yourself. Some of the main configuration files in the nodes directory will be explained in detail later.

Environmental requirements

Install ubuntu dependencies

sudo apt install -y openssl curl

Install centos dependencies

sudo yum install -y openssl openssl-devel

Create an operating directory and download the installation script

## 创建操作目录
cd ~ && mkdir -p fisco && cd fisco

## 下载脚本
curl -#LO https://github.com/FISCO-BCOS/FISCO-BCOS/releases/download/v2.9.1/build_chain.sh && chmod u+x build_chain.sh

After downloading, get the build_chain.sh script

annotation

If the build_chain.sh script cannot be downloaded for a long time due to network problems, please try curl -#LO https://osp-1257653870.cos.ap-guangzhou.myqcloud.com/FISCO-BCOS/FISCO-BCOS/releases/v2. 9.1/build_chain.sh && chmod u+x build_chain.sh

chmod u+x build_chain.sh adds execution permissions to ordinary users

Build a single group 4-node alliance chain

Execute the following command in the fisco directory to generate a single group 4-node FISCO chain. Please make sure that the machine's port30300~30303，20200~20203，8545~8548 is not occupied.

bash build_chain.sh -l 127.0.0.1:4 -p 30300,20200,8545

annotation

The -p option specifies the starting port, which are p2p_port, channel_port, and jsonrpc_port.

For security and ease of use, the latest configuration of version v2.3.0 splits listen_ip into jsonrpc_listen_ip and channel_listen_ip, but still retains the parsing function of listen_ip.

To facilitate development and experience, the reference configuration of channel_listen_ip is 0.0.0.0. For security reasons, please change it to a safe listening address based on the actual business network conditions, such as an internal IP or a specific external IP.

Start FISCO BCOS chain

Start all nodes

bash nodes/127.0.0.1/start_all.sh

Started successfully! ! !

Check progress

Check if the process is started

ps -ef | grep -v grep | grep fisco-bcos

Normally, there will be output similar to the following; if the number of processes is not 4, the process has not started (usually caused by the port being occupied)

Check log output

As follows, check the number of nodes linked to node node0

tail -f nodes/127.0.0.1/node0/log/log*  | grep connected

Execute the following command to check whether the consensus is reached

tail -f nodes/127.0.0.1/node0/log/log*  | grep +++
