8、Fabric 瀏覽器的部署

8.1 環(huán)境準(zhǔn)備

1、nodejs安裝，在第1節(jié)里已經(jīng)說過node的安裝，需要注意的是node版本應(yīng)該是v9.x以下。
2、PostgreSQL的安裝，瀏覽器會把監(jiān)聽到的數(shù)據(jù)存儲在pg里，所以需要安裝pg數(shù)據(jù)。
ubuntu使用直接安裝

sudo apt update
sudo apt install postgresql postgresql-contrib

安裝好后，可以使用cli查看一下

#切換用戶
sudo -i -u postgres
#進(jìn)入控制臺
psql
#退出
postgres=# \q

3、安裝Jq，jq是一個輕量級且靈活的命令行JSON處理器，安裝很簡單，見官網(wǎng)https://stedolan.github.io/jq/download/

8.2、下載瀏覽器源碼

? 在github上下載fabric 瀏覽器的源碼，https://github.com/hyperledger/blockchain-explorer，把源碼拉下來，根據(jù)自己的需要選擇不用的版本，我目前使用的是1.1版本，所以我切換到對應(yīng)的1.1分支上。

8.3、修改配置

8.3.1 配置postgresql數(shù)據(jù)庫

? 進(jìn)入 app/persistence/postgreSQL/db/文件夾，找到pgconfig.json配置文件，修改連接pg數(shù)據(jù)庫的配置，默認(rèn)配置為

{
  "pg": {
    "host": "127.0.0.1",
    "port": "5432",
    "database": "fabricexplorer",
    "username": "hppoc",
    "passwd": "password"
  }
}

修改支運行createdb.sh腳本文件，創(chuàng)建瀏覽器所需的數(shù)據(jù)庫和表名。

8.3.2、配置啟動abric瀏覽器文件

進(jìn)入 blockchain-explorer/app/platform/fabric，找到對應(yīng)的config.json文件，配置對應(yīng)的fabric網(wǎng)絡(luò)信息，包括節(jié)點的請求接口，及監(jiān)聽接口，不同瀏覽器版本這個配置文件不太一樣，1.1版本的配置文件如下：

配置各節(jié)點的信息及tls的ca證書，管理員的私鑰及證書等信息。

8.3.3、構(gòu)建node項目

1、進(jìn)入blockchain-explorer/ 下，使用npm install 安裝項目所需package，
2、再進(jìn)入blockchain-explorer/app/test/下，使用npm install 安裝測試項目里的所需包，再跑測試腳本

#安裝包
npm install

#運行測試腳本
npm run test

3、進(jìn)入client/ 使用npm install 命令安裝包

npm install

npm test -- -u --coverage

npm run build

8.4、啟動fabric瀏覽器

? 使用腳本./start.sh來啟動項目，啟動成功后，可以打開瀏覽器查看一下.

瀏覽器截圖

其中做了一些漢化。

已完結(jié)
