blockchain-explorer（pg版） 部署及配置详解
前置工具：
Git
Node.js 8.11.X 高版本暂不支持
PostgreSQL 9.5 以上 此处使用10
本篇部署环境：Ubuntu
准备环境：
安装git
sudo apt-get install git
安装node 8.11
因为版本限制，采用源码安装
#路径为 /usr/local
cd /usr/local
sudo wget https://npm.taobao.org/mirrors/node/latest-v8.x/node-v8.11.1-linux-x64.tar.xz
sudo tar xvf node-v8.11.1-linux-x64.tar.xz
cd node-v8.11.1-linux-x64/bin
./node -v #此时显示 8.11.1
sudo vim ~/.bashrc
#在打开文件的最后一行添加
export PATH=/usr/local/node-v8.11.1-linux-x64/bin:$PATH
#打开一个新的终端node -v 验证
安装Postgresql
#查看unbuntu版本
cat /etc/issue
#参数YOUR_UBUNTU_VERSION_HERE为 xenial(16.04)/bionic(18.04)/trusty(14.04)
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ YOUR_UBUNTU_VERSION_HERE-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
#例，版本为16.04 => deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main
sudo apt-get install wget ca-certificates
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql-10
psql --version #验证版本
开始部署
下载代码
这里直接取用了master的代码
git clone https://github.com/hyperledger/blockchain-explorer.git
下载fabric工具
这里下载的目前最新的1.2版本，就是fabric configtxgen 之类的工具包，部署fabric时应该已下载。
VERSION=1.2.0
ARCH=$(echo "$(uname -s|tr '[:upper:]' '[:lower:]' | sed 's/mingw64_nt.*/windows/')-$(uname -m | sed 's/x86_64/amd64/g')" | awk '{print tolower($0)}')
curl https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/${ARCH}-${VERSION}/hyperledger-fabric-${ARCH}-${VERSION}.tar.gz | tar xz
postgresql配置成可访问并开启服务
先启动pg
$sudo systemctl enable postgresql
$sudo systemctl start postgresql
//检查是否启动成功
$sudo systemctl status postgresql
ubuntu@ubuntu00:~$ sudo systemctl status postgresql
● postgresql.service - PostgreSQL RDBMS
Loaded: loaded (/lib/systemd/system/postgresql.service; enabled; vendor preset: enabled)
Active: active (exited) since Fri 2018-08-03 14:12:16 CST; 4h 22min ago
Main PID: 10398 (code=exited, status=0/SUCCESS)
CGroup: /system.slice/postgresql.service
Aug 03 14:12:16 ubuntu00 systemd[1]: Starting PostgreSQL RDBMS...
Aug 03 14:12:16 ubuntu00 systemd[1]: Started PostgreSQL RDBMS.
Aug 03 14:12:28 ubuntu00 systemd[1]: Started PostgreSQL RDBMS.
Aug 03 18:34:24 ubuntu00 systemd[1]: Started PostgreSQL RDBMS.
#绿色则启动成功
再进入pg执行代码中的数据库脚本 （老版本）
$ cd blockchain-explorer/
# 进入控制台
$ sudo -u postgres psql
#变成这样子
ubuntu@ubuntu00:~$ cd blockchain-explorer/
ubuntu@ubuntu00:~/blockchain-explorer$ sudo -u postgres psql
psql (10.4 (Ubuntu 10.4-2.pgdg16.04+1))
Type "help" for help.
#执行语句，这里是相对路径
postgres=# \i app/persistence/postgreSQL/db/explorerpg.sql
#上一句执行完会进入此数据库，再执行
fabricexplorer=# \i app/persistence/postgreSQL/db/updatepg.sql
#查看已有数据库
\l
#查看已创建表
\d
#退出
\q
-----------------------------------2018.8.16更新-------------------------------------------------
官方更新了release3.5的代码，更新了创建数据库脚本，新步骤如下，仍可用上一步得方法查看脚本执行结果。
$sudo apt-get install jq
$cd blockchain-explorer/app/persistence/postgreSQL/db
$./createdb.sh
修改pg访问权限，重启pg
//进入配置文件目录
$ cd /etc/postgresql/10/main
//修改访问控制文件
$ sudo vi postgresql.conf
把这里原来的注释取消掉
listen_addresses = 'localhost'
$ sudo vi pg_hba.conf
在此处插入一行或直接在最上面
# TYPE DATABASE USER ADDRESS METHOD
host all all 0.0.0.0/0 md5
$ systemctl restart postgresql
修改数据库配置
$cd blockchain-explorer/app/persistence/postgreSQL/db
$vi pgconfig.json

#若在本机，一般无需改动
配置fabric网络
$vi blockchain-explorer/app/platform/fabric/config.json

启动
$sudo apt-get install make
$sudo apt-get install g++ #可能有遗漏，就是安装一些C语言编译相关的插件，install时根据错误提示安装即可
$cd blockchain-explorer
$npm install
$cd blockchain-explorer/app/test
$npm install
$npm run test
$cd client/
$npm install
$npm test -- -u --coverage
#这一步可能非常慢，试了几次有的机器几分钟，有时一个小时
$npm run build
#表示返回
$cd blockchain-explorer
#端口配置在blockchain-explorer/appconfig.json文件，默认8080
$./start.sh
#看日志是否报错,有时候启动失败的话需要一定的时候才会打印错误日志
$cat logs/console/console-xxxxxxx.log
$./stop.sh
-----------------------------------2018.8.9更新-------------------------------------------------
若部署的是fabric1.2，目前不能用master版本代码，可切换release3.5版本，而且仍有BUG，对最新的fabric并不能完全兼容。
