需要准备的环境：
1, Go 1.15.6
2, Node.js v12.13.1
3, jq
4, gcc-c++
5,postgresql-9.5
软件下载及安装方式：
这里我只列出jq,gcc-c++,postgresql-9.5的安装，其他软件请参考之前的文章完成
jq安装：
yum install -y jq
gcc-c++安装：
yum install -y gcc-c++
postgresql-9.5安装：
先安装yum源：
yum install -y https://download.postgresql.org/pub/repos/yum/9.5/redhat/rhel-7.4-x86_64/pgdg-redhat-repo-42.0-11.noarch.rpm
下来再安装postgresql-9.5
yum install -y postgresql95-server postgresql95-contrib
systemctl enable postgresql-9.5.service
systemctl start postgresql-9.5.service
修改postgresql的密码
su - postgres
psql -U postgres #默认用户
ALTER USER postgres WITH PASSWORD '123456' #密码
\q #退出
exit
开启远程访问：
vim /var/lib/pgsql/9.5/data/postgresql.conf # 修改#listen_addresses = 'localhost' 为 listen_addresses='*'
信任远程连接：
vim /var/lib/pgsql/9.5/data/pg_hba.conf #填加一行
host all all 0.0.0.0/0 trust
重启postgresql
systemctl restart postgresql-9.5.service
你可以通过navicat尝试去连接如果可以说明一切都配置正常
完成后就可以了，下面是我的软件安装的路径：
其中有些软件不需要，可以不用安装
我的工作目录是/usr/local下，所以后面所有的操作及配置也都会基于此目录
安装完成nodejs和go以后记得去配置环境变量
到这里环境就准备好了
下载fabric-simple 和fabric-explorer
此下载需要Git，没有的提前装，这里不过多介绍
cd /usr/local/gopath/src/github.com/hyperledger
git clone -b v1.1.4 https://github.com/hyperledger/blockchain-explorer.git
我选择这个版本是因为在我安装时这个版本是最新的，一面出现版本不兼容这里特别记录出来
我的gopath是在/usr/local/下
fabric-simple 我下载在了/usr/local/下，当然你也可以放到gopath 下，会和blockchain-explorer同级
cd /usr/local
git clone -b v.1.4.3 https://github.com/hyperledger/fabric-samples.git
我这里用的是v1.4.3的版本
启动fabric-simple
cd /usr/local/fabric-samples/first-network
./byfn.sh generate
./byfn.sh up
修改blockchain-explorer的配置信息
cd /usr/local/gopath/src/github.com/hyperledger/blockchain-explorer/app
vim appconfig.json #修改"host": "localhost", 为"host": "虚拟机ip", 端口修改为8089
[root@bogon app]# cat appconfig.json
{
"sslEnabled": false,
"sslCertsPath": "ssl-certs",
"host": "192.168.56.19",
"port": "8089",
"license": "Apache-2.0"
}
[root@bogon app]#
vim explorerconfig.json #改文件和上面的文件同级，修改postgresql的连接信息
[root@bogon app]# cat explorerconfig.json
{
"persistence": "postgreSQL",
"platforms": ["fabric"],
"postgreSQL": {
"host": "127.0.0.1",
"port": "5432",
"database": "postgres",
"username": "postgres",
"passwd": "123456"
},
"sync": {

"platform": "fabric",
"blocksSyncTime": "1"
},
"jwt": {
"secret": "a secret phrase!!",
"expiresIn": "2h"
}
}
[root@bogon app]#
导入数据库信息：
cd /usr/local/gopath/src/github.com/hyperledger/blockchain-explorer/app/persistence/fabric/postgreSQL/db
./createdb.sh
完成后查看数据库可以看到多了一些表
explorer和fabric-simple例子结合
cd /usr/local/gopath/src/github.com/hyperledger/blockchain-explorer/app/platform/fabric
vim config.json
[root@bogon fabric]# cat config.json
{
"network-configs": {
"first-network": {
"name": "first Network",
"profile": "./connection-profile/first-network.json"
}
},
"license": "Apache-2.0"
}
编辑first-network.json文件，此文件原来是不存在的，我们需要将test-network.json文件复制一份进行改动
cd /usr/local/gopath/src/github.com/hyperledger/blockchain-explorer/app/platform/fabric/connection-profile
cp test-network.json first-network.json
[root@bogon connection-profile]# cat first-network.json

[root@bogon connection-profile]#
需要修改的地方我都标红和可以根据自己安装的fabric-simple进行配置
下来我们来打包部署explorer
cd /usr/local/gopath/src/github.com/hyperledger/blockchain-explorer
npm install
cd client/
npm install
npm run build
以上命令如果出现权限问题可以用以下方式解决
npm config set unsafe-perm true
然后再执行上面的命令
完成后我们就可以启动exporer了
用下面的命令启动
cd /usr/local/gopath/src/github.com/hyperledger/blockchain-explorer
npm start
启动输出：
[root@bogon blockchain-explorer]# npm start
> hyperledger-explorer@1.1.4 start /usr/local/gopath/src/github.com/hyperledger/blockchain-explorer
> run-s build app-start
> hyperledger-explorer@1.1.4 build /usr/local/gopath/src/github.com/hyperledger/blockchain-explorer
> tsc
> hyperledger-explorer@1.1.4 app-start /usr/local/gopath/src/github.com/hyperledger/blockchain-explorer
> ./start.sh
************************************************************************************
**************************** Hyperledger Explorer **********************************
************************************************************************************
[root@bogon blockchain-explorer]#
用下面的命令停止
npm run app-stop
停止输出
[root@bogon blockchain-explorer]# npm run app-stop
> hyperledger-explorer@1.1.4 app-stop /usr/local/gopath/src/github.com/hyperledger/blockchain-explorer
> ./stop.sh
Stopping node process hyperledger-explorer, id 19062
