Editor to share with you how to use the official browser of Fabric blockchain, I believe most people do not know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. Let's learn about it together.

Blockchain-explorer is the official blockchain browser provided by Hyperledger, which currently supports Fabric 1.4.x blockchain. Download address: https://github.com/ezpod/blockchain-explorer/.

The official installation steps are a little complicated, the Chinese version of the detailed installation instructions here. The following is a quick installation guide:

1. Start the sample network of Fabric

First, refer to the official documentation of the Fabric blockchain to install and launch the first-network network in fabric-samples:

~ / fabrc-samples$. / byfn.sh up-l node

If it is a windows system, you can use this Fabric blockchain one-click installation tool.

2. Install the basic software required by the Fabric Block chain browser

Before installing and configuring the Fabric browser, you need to install the following software on the local machine:

Postgresql 9.5

Nodejs 8-10-12

Docker CE 18.09.2 +

Docker Compose 1.14.0

3. Download the Chinese version of the Fabric blockchain browser code

Download the code of the Chinese version of the Fabric blockchain browser locally using the following command:

~ $git clone https://github.com/ezpod/blockchain-explorer.git4, configure the connection to the Fabric network

Modify the following configuration user identity MSP path that is used by Fabric browsers to access the Fabric network:

Blockchain-explorer/app/platform/fabric/connection/first-network.json

There are three points involved, which are modified by referring to your own fabric-smaples path:

Organizations-> Org1MSP-> adminPrivateKey

Organizations-> Org1MSP-> signedCert

Peers-> peer0.org1.example.com-> tlsCACerts-> papth

5. Initialize the postgresql database

Initialize the postgresql database by executing the following command:

~ $cd blockchain-explorer/app/persistence/fabric/postgreSQL/db~/blockchain-explorer/app/persistence/fabric/postgreSQL/db$ sudo-u postgres. / createdb.sh

Note that the createdb.sh script requires nodejs support, so you can access node by switching to the postgres account.

6. Build fabric block chain browser.

Execute the following command: back-end service and front-end application of fabric block chain browser:

~ $cd blockchain-explorer~/blockchain-explorer$. / main.sh install7, start the Fabric blockchain browser service

Execute the following command to start the fabric blockchain browser service:

~ / blockchain-explorer$. / start.sh

This is a background process, so when started, it returns to the command line prompt. This is normal. At this point, you should already be listening on port 8080, and you can access it using a browser. On the first visit, you will automatically go to the login interface:

Note that the login account and password are associated with the network. For first-network, the default user name is admin and the password is adminpw. You can configure it in the file mentioned earlier:

Blockchain-explorer/app/platform/fabric/connection/first-network.json

If you need to stop the fabric blockchain browser from running, execute the following command:

~ / blockchain-exlorer$. / stop.sh

If it is inaccessible or abnormal in the browser after startup, you can refer to the log file of the Fabric browser for troubleshooting:

Logs/app/app.log

Logs/console/console.log

Logs/db/db.log
