EOS mongodb + GraphQL 查询

 2018-08-30　  Surou　  阅读 　  EOS-新手教程　  0 评论

为了更灵活的查询EOS blocks入库到MongoDB的数据，我们将支持 GraphQL

GraphQL

GraphQL 既是一种用于 API 的查询语言也是一个满足你数据查询的运行时。 GraphQL 对你的 API 中的数据提供了一套易于理解的完整描述，使得客户端能够准确地获得它需要的数据，而且没有任何冗余，也让 API 更容易地随着时间推移而演进，还能用于构建强大的开发者工具。

项目支持

基于开源项目 eosio-graphql 提供GraphQL支持
此项目内部依赖 eosio-mongodb-queries提供MongoDB查询支持

开始部署

clone代码

git clone https://github.com/EOS-BP-Developers/eosio-graphql.git

进入源码目录，安装依赖

cd eosio-graphql
npm i
npm 安装参考 ubuntu npm 升级到新版

修改项目配置

修改 config.ts文件中的 MongoDB uri为本地配置的MongoDB配置

export const MONGODB_URI = process.env.MONGODB_URI || "mongodb://localhost:20000";

编辑index.ts 修改远程访问地址和端口

export function eosGraphQLGateway(config: any = {}) {
  const {
    host = "0.0.0.0",
    port = 443,
    mongoClient,
    buildSchema = defaultBuildSchema,
    buildResolvers = defaultBuildResolvers,
    abiDir = "",
  } = config;

运行项目

npm start
  • 如果出现Error: Cannot find module 'typescript/tsc.js'
    sudo npm install -g typescript

此时程序已经运行

> eosio-graphql@0.2.0 start /mnt/data/eosio-graphql
> tsc && node service.js

?. Server ready at http://0.0.0.0:443/graphql

访问服务器

访问服务器ip:端口/graphql
测试查询

query {
  blocks(sort: { block_num: -1 }, match: { irreversible: true }) {
    block_num
    irreversible
    block {
      producer
    }
  }
}

注意

由于eosio-mongodb-queries项目中写死了查询的EOS在MongoDB数据库名称为EOS（区分大小写），所以要将nodeos同步到MongoDB数据库时，确认数据库名字为EOS

plugin = eosio::mongo_db_plugin
mongodb-uri = mongodb://localhost:20000/EOS
mongodb-filter-on = *

常规保证EOS智能合约资金安全

 2018-08-28　  Surou　  阅读 　  EOS-新手教程　  0 评论

方法一：多重签名智能合约

EOS权限体系通过权重（Weight）和阈值（Threshold）来限制合约账户，可以实现多个人共同管理一个账户资金，假设智能合约账户有5个人的公钥，每个公钥的权重为1，权限的总阈值为3，这就表示必须要这5个人中至少3个人签名，才可以转移资金和修改合约代码。

方法二：移交智能合约权限

这种方式也比较安全，我们可以修改合约权限为eosio.prods账户，直接将智能合约权限移交给官方21个节点来控制，未来如果需要转移资金或修改合约，则需要申请节点仲裁。

方法三：设置合约黑洞公钥

这种方式是最接近区块链定义的，我们可以将智能合约权限修改为黑洞公钥，官方在超级节点竞选时临时用过的这个公钥：EOS1111111111111111111111111111111114T1Anm，它的公钥是0值加检验数据生成的，任何人都不知道它的私钥，未来合约也不可能再被转移资金或修改。

搭建EOS MongoDB 分片集群

 2018-08-24　  Surou　  阅读 　  EOS-新手教程　  0 评论

由于EOS blocks数据同步到Mongo数据库后，体积很大，查询缓慢，并且机器配置比较低，同时运行nodeos写入MongoDB有点遭不住，so，部署下mongo集群，并做分片配置

1. 安装 MongoDB

准备了三台分别1T存储的云主机。三台主机在同一内网，IP分别如下

172.31.32.31 172.31.32.29 172.31.32.30
mongos mongos mongos
config server config server config server
shard server1 主节点 shard server1 副节点 shard server1 仲裁
shard server2 仲裁 shard server2 主节点 shard server2 副节点
shard server3 副节点 shard server3 仲裁 shard server3 主节点

端口分配：

占用 端口
mongos 20000
config 21000
shard1 27001
shard2 27002
shard3 27003

分别在每台机器建立conf、mongos、config、shard1、shard2、shard3六个目录，
因为mongos不存储数据，只需要建立日志文件目录即可。/mnt/data为机器挂载的1T存储盘

mkdir -p /mnt/data/mongodb/conf \
mkdir -p /mnt/data/mongodb/mongos/log \
mkdir -p /mnt/data/mongodb/config/data \
mkdir -p /mnt/data/mongodb/config/log \
mkdir -p /mnt/data/mongodb/shard1/data \
mkdir -p /mnt/data/mongodb/shard1/log \
mkdir -p /mnt/data/mongodb/shard2/data \
mkdir -p /mnt/data/mongodb/shard2/log \
mkdir -p /mnt/data/mongodb/shard3/data \
mkdir -p /mnt/data/mongodb/shard3/log

安装 mongodb-server

sudo apt install mongodb-server

配置环境变量

vi /etc/profile
# MongoDB 环境变量内容
export MONGODB_HOME=~/opt/mongodb
export PATH=$MONGODB_HOME/bin:$PATH

使立即生效

source /etc/profile

2. config server配置服务器

mongodb3.4以后要求配置服务器也创建副本集，不然集群搭建不成功。
(三台机器)添加配置文件 vi /mnt/data/mongodb/conf/config.conf

## Profile content
pidfilepath = /mnt/data/mongodb/config/log/configsrv.pid
dbpath = /mnt/data/mongodb/config/data
logpath = /mnt/data/mongodb/config/log/congigsrv.log
logappend = true

bind_ip = 0.0.0.0
port = 21000
fork = true

#declare this is a config db of a cluster;
configsvr = true

#Replica set name
replSet = configs

#Set the maximum number of connections
maxConns = 20000

启动三台服务器的config server

mongod -f /mnt/data/mongodb/conf/config.conf

登录任意一台配置服务器，初始化配置副本集

连接 MongoDB

mongo --port 21000

config 变量

config = {
    _id : "configs",
    members : [
    {_id : 0, host : "172.31.32.31:21000" },
    {_id : 1, host : "172.31.32.29:21000" },
    {_id : 2, host : "172.31.32.30:21000" }
    ]
}

初始化副本集

rs.initiate(config)

其中，"_id" : "configs"应与配置文件中配置的 replicaction.replSetName 一致，"members" 中的 "host" 为三个节点的 ip 和 port
响应内容如下

> config = {
...     _id : "configs",
...     members : [
...     {_id : 0, host : "172.31.32.31:21000" },
...     {_id : 1, host : "172.31.32.29:21000" },
...     {_id : 2, host : "172.31.32.30:21000" }
...     ]
... }
{
    "_id" : "configs",
    "members" : [
        {
            "_id" : 0,
            "host" : "172.31.32.31:21000"
        },
        {
            "_id" : 1,
            "host" : "172.31.32.29:21000"
        },
        {
            "_id" : 2,
            "host" : "172.31.32.30:21000"
        }
    ]
}
> rs.initiate(config)
{
    "ok" : 1,
    "operationTime" : Timestamp(1535116186, 1),
    "$gleStats" : {
        "lastOpTime" : Timestamp(1535116186, 1),
        "electionId" : ObjectId("000000000000000000000000")
    },
    "$clusterTime" : {
        "clusterTime" : Timestamp(1535116186, 1),
        "signature" : {
            "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
            "keyId" : NumberLong(0)
        }
    }
}
configs:SECONDARY> rs.status()

此时会发现终端上的输出已经有了变化。

//从单个一个
>
//变成了
configs:SECONDARY>

查询状态

configs:SECONDARY> rs.status()

输出如下

configs:SECONDARY> rs.status()

3. 配置分片副本集

3.1 设置第一个分片副本集

(三台机器)设置第一个分片副本集
配置文件vi /mnt/data/mongodb/conf/shard1.conf

pidfilepath = /mnt/data/mongodb/shard1/log/shard1.pid
dbpath = /mnt/data/mongodb/shard1/data
logpath = /mnt/data/mongodb/shard1/log/shard1.log
logappend = true

bind_ip = 0.0.0.0
port = 27001
fork = true
replSet = shard1

#declare this is a shard db of a cluster;
shardsvr = true
maxConns = 20000

启动三台服务器的shard1 server

mongod -f /mnt/data/mongodb/conf/shard1.conf

登陆任意一台服务器，初始化副本集(除了172.31.32.30)
连接 MongoDB

mongo --port 27001

使用admin数据库

use admin

定义副本集配置

config = {
    _id : "shard1",
     members : [
         {_id : 0, host : "172.31.32.31:27001" },
         {_id : 1, host : "172.31.32.29:27001" },
         {_id : 2, host : "172.31.32.30:27001" , arbiterOnly: true }
     ]
 }

初始化副本集配置

rs.initiate(config)

响应内容如下

> use admin
switched to db admin
> config = {
...     _id : "shard1",
...      members : [
...          {_id : 0, host : "172.31.32.31:27001" },

{
        "_id" : "shard1",

                },
                {
                        "_id" : 1,
                        "host" : "172.31.32.29:27001"
                },
                {
                        "_id" : 2,
                        "host" : "172.31.32.30:27001",
                        "arbiterOnly" : true
                }
        ]
}
> rs.initiate(config)
{ "ok" : 1 }

3.2 设置第二个分片副本集

设置第二个分片副本集
配置文件 vi /mnt/data/mongodb/conf/shard2.conf

pidfilepath = /mnt/data/mongodb/shard2/log/shard2.pid
dbpath = /mnt/data/mongodb/shard2/data
logpath = /mnt/data/mongodb/shard2/log/shard2.log
logappend = true

bind_ip = 0.0.0.0
port = 27002
fork = true

replSet=shard2

#declare this is a shard db of a cluster;
shardsvr = true
maxConns=20000

启动三台服务器的shard2 server

mongod -f /mnt/data/mongodb/conf/shard2.conf

连接 MongoDB

mongo --port 27002

使用admin数据库

use admin

定义副本集配置

config = {
    _id : "shard2",
     members : [
         {_id : 0, host : "172.31.32.31:27002"  , arbiterOnly: true },
         {_id : 1, host : "172.31.32.29:27002" },
         {_id : 2, host : "172.31.32.30:27002" }
     ]
 }

初始化副本集配置

3.4 配置路由服务器 mongos

（三台机器）先启动配置服务器和分片服务器,后启动路由实例启动路由实例:
修改配置文件vi /mnt/data/mongodb/conf/mongos.conf

pidfilepath = /mnt/data/mongodb/mongos/log/mongos.pid
logpath = /mnt/data/mongodb/mongos/log/mongos.log
logappend = true

bind_ip = 0.0.0.0
port = 20000
fork = true

#The configuration server that listens can only have 1 or 3 configs to configure the replica set name of the server.
configdb = configs/172.31.32.31:21000,172.31.32.29:21000,172.31.32.30:21000

maxConns = 20000

启动三台服务器的mongos server

mongos -f /mnt/data/mongodb/conf/mongos.conf

4. 串联路由服务器

目前搭建了mongodb配置服务器、路由服务器，各个分片服务器，不过应用程序连接到mongos路由服务器并不能使用分片机制，还需要在程序里设置分片配置，让分片生效。
登陆任意一台mongos

mongo --port 20000

使用admin数据库

use admin

串联路由服务器与分配副本集

sh.addShard("shard1/172.31.32.31:27001,172.31.32.29:27001,172.31.32.30:27001");
sh.addShard("shard2/172.31.32.31:27002,172.31.32.29:27002,172.31.32.30:27002");

5. 启用集合分片生效

目前配置服务、路由服务、分片服务、副本集服务都已经串联起来了，但我们的目的是希望插入数据，数据能够自动分片。连接在mongos上，准备让指定的数据库、指定的集合分片生效。
登陆任意一台mongos

mongo --port 20000

使用admin数据库

use admin

指定eos数据库分片生效

db.runCommand( { enablesharding :"eos"});

指定数据库里需要分片的集合和片键，哈希id 分片

db.runCommand( { shardcollection : "eos.blocks",key : {"_id": "hashed"} } );

6. 修改eos config.ini

三台机器其中一台，运行nodeos并同步blocks数据到mongodb

plugin = eosio::mongo_db_plugin
mongodb-uri = mongodb://localhost:20000/eos

重置数据

nodeos --data-dir /mnt/data/data --hard-replay-blockchain --mongodb-wipe

需要清空数据的话加下 --mongodb-wipe
然后查看任意一台mongo数据库

mongo --port 20000
mongos> show databases;
admin   0.000GB
config  0.001GB
eos     0.071GB

已经正确分片存储
