8、Fabric 瀏覽器的部署
8.1 環(huán)境準備
1唇礁、nodejs安裝，在第1節(jié)里已經(jīng)說過node的安裝惨篱，需要注意的是node版本應該是v9.x以下盏筐。
2、PostgreSQL的安裝砸讳，瀏覽器會把監(jiān)聽到的數(shù)據(jù)存儲在pg里琢融，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
安裝好后簿寂，可以使用cli查看一下
#切換用戶
sudo -i -u postgres
#進入控制臺
psql
#退出
postgres=# \q
3漾抬、安裝Jq，jq是一個輕量級且靈活的命令行JSON處理器常遂，安裝很簡單纳令，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 瀏覽器的源碼烈钞，https://github.com/hyperledger/blockchain-explorer泊碑，把源碼拉下來，根據(jù)自己的需要選擇不用的版本毯欣，我目前使用的是1.1版本馒过，所以我切換到對應的1.1分支上。
8.3酗钞、修改配置
8.3.1 配置postgresql數(shù)據(jù)庫
? 進入 app/persistence/postgreSQL/db/文件夾腹忽，找到pgconfig.json配置文件，修改連接pg數(shù)據(jù)庫的配置砚作，默認配置為
{
"pg": {
"host": "127.0.0.1",
"port": "5432",
"database": "fabricexplorer",
"username": "hppoc",
"passwd": "password"
}
}
修改支運行createdb.sh腳本文件窘奏，創(chuàng)建瀏覽器所需的數(shù)據(jù)庫和表名。
8.3.2葫录、配置啟動abric瀏覽器文件
進入 blockchain-explorer/app/platform/fabric着裹，找到對應的config.json文件，配置對應的fabric網(wǎng)絡信息米同，包括節(jié)點的請求接口骇扇，及監(jiān)聽接口摔竿，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證書少孝，管理員的私鑰及證書等信息继低。
8.3.3、構建node項目
1稍走、進入blockchain-explorer/ 下袁翁，使用npm install 安裝項目所需package，
2婿脸、再進入blockchain-explorer/app/test/下粱胜，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盖淡、進入client/ 使用npm install 命令安裝包
npm install
npm test -- -u --coverage
npm run build
8.4年柠、啟動fabric瀏覽器
? 使用腳本./start.sh來啟動項目，啟動成功后褪迟，可以打開瀏覽器查看一下.
其中做了一些漢化。
已完結
