准备工作

1、 安装Nodejs 10.19.0

wget https://nodejs.org/download/release/v10.19.0/node-v10.19.0-linux-x64.tar.gz
tar -xvf node-v10.19.0-linux-x64.tar.gz
sudo ln -s /home/ubuntu/node-v10.19.0-linux-x64/bin/node
/usr/local/bin/node
sudo ln -s /home/ubuntu/node-v10.19.0-linux-x64/bin/npm
/usr/local/bin/npm
mv /home/ubuntu/node-v8.14.0-linux-x64  /home/ubuntu/node
vim /etc/profile  #修改profile加入下面内容
export PATH="$PATH:/home/ubuntu/node/bin"

2、 PostgreSQL 9.5以上，我用的是10
更新 apt 包索引

sudo apt-get update

安装数据库，安装后会自动添加postgres 的操作系统用户，密码是随机的

sudo apt-get install postgresql

打开客户端工具 psql

sudo -u postgres psql

修改 postgres 数据库用户的密码为123456

postgres=# ALTER USER postgres WITH
PASSWORD '123456'; 

退出 psql

postgres=# \q

修改 ubuntu 操作系统的 postgres 用户的密码

sudo passwd -d postgres
sudo -u postgres passwd

修改配置实现远程访问

vi /etc/postgresql/10/main/postgresql.conf

修改连接权限

#listen_addresses = 'localhost' 改为 listen_addresses = '*'

设置所有用户可连接

vi /etc/postgresql/10/main/pg_hba.conf

在最后一行插入以下内容

host all all 0.0.0.0/0 md5

重启服务

/etc/init.d/postgresql restart

3、安装 Jq

sudo apt-get install jq

验证版本

jq -V

4、 Docker CE 18.09.2 or later
5、 Docker Compose 1.14.0
6、 保证first-network可以运行

开始搭建
拉取项目

git clone https://github.com/hyperledger/blockchain-explorer.git
#太慢的话用码云

进入目录

cd blockchain-explorer

修改配置文件

进入目录blockchain-explorer/app，默认配置就好，其实不需要修改

vim explorerconfig.json

cd blockchain-explorer/app/persistence/fabric/PostgreSQL
chmod -R 775 db/
cd db

查看是否创建成功
连接 postgresSQL

sudo -u postgres psql

查看已有数据库

\l

创建表

\d

退出

\q

修改配置文件

cd blockchain-explorer/app
"jwt": {
"secret" : "a secret phrase!!",
"expiresIn": "2 days"
}

启动first-network

./byfn.sh up

修改first-network.json配置文件

(1) 把搭建Fabric网络时生成的crypto-config复制到blockchain-explorer目录下任意位置。

(2) 替换organizations和peers下的证书位置，最好使用全路径。使用全路径时，需要把fullpath设为true.

构建Hyperledger Explorer

cd ~
cd blockchain-explorer/
./main.sh install
./main.sh test

运行

cd ~
cd blockchain-explorer/
./start.sh

可能出现的错误

./createdb.sh
could not change
directory to "/home/dc2-user/kongli/blockchain-explorer/app/persistence/postgreSQL/db":
权限不够

需要把blockchain-explorer下载在非当前用户文件夹下，比如/tmp
