Hyperledger Explorer Download
cd /opt/gopath/src/github.com/hyperledger
git clone https://github.com/hyperledger/blockchain-explorer.git
create database
We use the default version for database creation:
cd blockchain-explorer/app
vi explorerconfig.json
Modify the configuration as follows:
{
"persistence": "postgreSQL",
"platforms": ["fabric"],
"postgreSQL": {
"host": "127.0.0.1",
"port": "5432",
"database": "fabricexplorer",
"username": "postgres",
"passwd": "postgres"
},
"sync": {
"type": "local",
"platform": "fabric",
"blocksSyncTime": "1"
},
"jwt": {
"secret": "a secret phrase!!",
"expiresIn": "2h"
}
}
Run the script that creates the database
cd /opt/gopath/src/github.com/hyperledger/blockchain-explorer/app/persistence/fabric/postgreSQL/db
./createdb.sh
View database status command:
sudo -u postgres psql -c '\l'
sudo -u postgres psql fabricexplorer -c '\d'
Define fabric network connection parameters
cd /opt/gopath/src/github.com/hyperledger/blockchain-explorer/app/platform/fabric/
vim config.json
Set enableAuthentication attribute false to turn off login authentication
{
"network-configs": {
"first-network": {
"name": "firstnetwork",
"profile": "./connection-profile/first-network.json",
"enableAuthentication": false
}
},
"license": "Apache-2.0"
}
Set first-network.json configuration
Continue to set up (the Fabric network environment must be in a normal startup state, otherwise the file in the following path does not exist)
cd /opt/gopath/src/github.com/hyperledger/blockchainexplorer/app/platform/fabric/connection-profile/
vim first-network.json
The key settings are as follows:

}
}
}- adminCredential Set the user password for browser login
- channels set channel name, peer0 name
- organizations Set the certification path
- peers set peer-ca certificate path
- certificateAuthorities set ca certificate path
Note: It needs to be explained that these two "tlsCACerts" are not in the same dictionary, special attention should be paid when configuring, and the file path of your own is the main one.
