注意：更新yum源，163或者阿里的yum源都可以

添加RPM
    yum install https://download.postgresql.org/pub/repos/yum/9.5/redhat/rhel-7-x86_64/pgdg-centos95-9.5-3.noarch.rpm


安装PostgreSQL 9.5
    yum install postgresql95-server postgresql95-contrib

初始化数据库
    /usr/pgsql-9.5/bin/postgresql95-setup initdb
设置开机自启动
    systemctl enable postgresql-9.5.service

启动服务
    systemctl start postgresql-9.5.service
查看服务运行状态
	systemctl status postgresql-9.5.service

postgreSQL 安装完成后，会建立一下‘postgres’用户，用于执行PostgreSQL，数据库中也会建立一个’postgres’用户，默认密码为自动生成，需要在系统中改一下。

修改用户密码

1

4
su - postgres  切换用户，执行后提示符会变为 '-bash-4.2$'
psql -U postgres 登录数据库，执行后提示符变为 'postgres=#'
ALTER USER postgres WITH PASSWORD 'gooagoo'  设置postgres用户密码
\q  退出数据库

开启远程访问

1
2
3
vi /var/lib/pgsql/9.5/data/postgresql.conf
修改#listen_addresses = 'localhost'  为  listen_addresses='*'
当然，此处‘*’也可以改为任何你想开放的服务器IP

信任远程连接

5
vi /var/lib/pgsql/9.5/data/pg_hba.conf
    修改如下内容，信任指定服务器连接
    # IPv4 local connections:
    host    all            all      127.0.0.1/32      trust
    host    all            all      10.211.55.6/32（需要连接的服务器IP）  trust

重启

1
systemctl restart postgresql-9.5.service

su - postgres
cd blockchain-explorer/app

修改explorerconfig.json以更新postgresql属性

postgreSQL主机，端口，数据库，用户名，密码详细信息。
“postgreSQL”：{

  "host": "127.0.0.1",
  "port": "5432",
  "database": "fabricexplorer",
  "username": "postgres",
  "passwd": "gooagoo"
}

运行create database脚本

cd blockchain-explorer/app/persistence/fabric/postgreSQL/db
./createdb.sh

tar xvf  node-v11.10.0-linux-x64.tar
cd node-v11.10.0-linux-x64
./configure  && make && make install


装cnpm淘宝源
npm install -g cnpm --registry=https://registry.npm.taobao.org

cd blockchain-explorer/app/test
cnpm install
cnpm run test
cd client/
cnpm install
cnpm test -- -u --coverage
cnpm run build

由于config.json还没有写配置，所以node test会测试不成功

完成之后，在执行上面的，cnpm test

cd /var/lib/pgsql/blockchain-explorer/client/src
将components替换成我百度链接的包

之后还需要重新，cnpm build一下

由于区块链浏览器默认需要有锚节点，才能显示所有节点，所以在部署了第一个组织之后，需要在升级下锚节点
./bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID vaccine -asOrg Org1MSP

docker exec -it cli-vaccine peer channel update -o orderer1.vaccine.syj.vaccine.com:7050 -c vaccine -f ./channel-artifacts/Org1MSPanchors.tx
