Node networking topology
A networking mode with 6 nodes, 3 organizations and 2 groups as shown in the figure. Organization B and Organization C are located in Group 1 and Group 2, respectively. Organization A belongs to both group 1 and group 2.
Machine environment
The IP and port numbers of each node are as follows:
| mechanism | node | Belonging to the group | P2P address | RPC | Channel listening address |
|---|---|---|---|---|---|
| Agency A | Node 0 | Group 1, 2 | 127.0.0.1:30300 | 127.0.0.1:8545 | 0.0.0.0:20200 |
| - | Node 1 | Group 1, 2 | 127.0.0.1:30301 | 127.0.0.1:8546 | 0.0.0.0:20201 |
| - | Node 4 | Group 1, 2 | 127.0.0.1:30304 | 127.0.0.1:8549 | 0.0.0.0:20202 |
| Organization B | Node 2 | Group 1 | 127.0.0.1:30302 | 127.0.0.1:8547 | 0.0.0.0:20203 |
| - | Node 3 | Group 1 | 127.0.0.1:30303 | 127.0.0.1:8548 | 0.0.0.0:20204 |
| Institution C | Node 5 | Group 1, 2 | 127.0.0.1:30305 | 127.0.0.1:8550 | 0.0.0.0:20205 |

FISCO BCOS practical operation
Download and install
cd ~/ && git clone https://github.com/FISCO-BCOS/generator.git
cd ~/generator && bash ./scripts/install.sh //安装
./generator -h //查看帮助信息
./generator --download_fisco ./meta //拉取最新fisco-bcos二进制文
./meta/fisco-bcos -v //查看版本
Alliance chain initialization
Initialization mechanism A, B
cp -r ~/generator ~/generator-A
cp -r ~/generator ~/generator-B
Initialize chain certificate
cd ~/generator
./generator --generate_chain_certificate ./dir_chain_ca //生成链证书ca.crt 链私钥ca.key
ls ./dir_chain_ca //查看链证书及私钥:ca.crt ca.key
//The organization generates the private key agency.key locally—>generates the request file—>the certificate issuing authority obtains the agency.crt
//生成机构A证书
./generator --generate_agency_certificate ./dir_agency_ca ./dir_chain_ca agencyA
ls dir_agency_ca/agencyA/ 查看机构证书、机构私钥、链证书
cp ./dir_agency_ca/agencyA/* ~/generator-A/meta/
//机构B证书
./generator --generate_agency_certificate ./dir_agency_ca ./dir_chain_ca agencyB
cp ./dir_agency_ca/agencyA/* ~/generator-A/meta/
Organization A modifies the configuration file
node_deployment.ini to be the node configuration file, and the operation and maintenance deployment tool will generate relevant node certificates according to the configuration under node_deployment.ini, and generate node configuration folders, etc.
cd ../generator-A
vim ~/generator-A/conf/node_deployment.ini
[node0]
p2p_listen_port=30300
channel_listen_port=20200
jsonrpc_listen_port=8545
[node1]
p2p_listen_port=30301
channel_listen_port=20201
jsonrpc_listen_port=8546
Modify node_deployment.ini file
Modify the following configuration
vim ~/generator-B/conf/node_deployment.ini
[node0]
p2p_listen_port=30302
channel_listen_port=20202
jsonrpc_listen_port=8547
[node1]
p2p_listen_port=30303
channel_listen_port=20203
jsonrpc_listen_port=8548
Organizations A and B generate and send node information
1, generate node certificates, and p2p connection address files
cd ~/generator-A & ./generator --generate_all_certificates ./agencyA_node_info
cd ~/generator-B & ./generator --generate_all_certificates ./agencyB_node_info
2. Mutual storage of p2p address files
cp ~/generator-A/agencyA_node_info/peers.txt ~/generator-B/meta/peersA.txt
cp ~/generator-B/agencyB_node_info/peers.txt ~/generator-A/meta/peersB.txt
3. Mutual storage of node certificates
cp ./agencyA_node_info/cert*.crt ~/generator-B/meta/
cp ./agencyB_node_info/cert*.crt ~/generator-A/meta/
Institution A generates group 1 genesis block
cd ~/generator-A
vim ~/generator-A/conf/group_genesis.ini //修改机构A配置文件，用来生成创世块
/修改以下信息
[group]
group_id=1
[nodes]
node0=127.0.0.1:30300
node1=127.0.0.1:30301
node2=127.0.0.1:30302
node3=127.0.0.1:30303
Generate genesis block, which will be distributed to institution B
./generator --create_group_genesis ./group //生成创世块
cp ./group/group.1.genesis ~/generator-B/meta //创世块分发
Generate A and B node information according to the node_deployment.ini file
cd ~/generator & ./generator --build_install_package ./meta/peersB.txt ./nodeA //生成节点nodeA
bash ./nodeA/start_all.sh //启动节点nodeA
cd ~/generator & ./generator --build_install_package ./meta/peersA.txt ./nodeB //生成节点nodeB
bash ./nodeB/start_all.sh
fisco bcos supports mysql as backend storage,
configure mysql storage
Modify the group.1.ini configuration file (30300, 30301, 30302, 30303) 4 files to configure the database
vim generator-A/nodeA/node_127.0.0.1_30300/conf/group.1.ini
修改配置如下：
type=mysql
db_username=root
db_passwd=123
db_name=自定义数据库名
Generate sdk certificate
cd generator-A & ./generator --generate_sdk_certificate ./dir_sdk_ca ./dir_agency_ca/agencyA/
