# 全节点账户历史插件使用教程

# 1. 插件概述

由于witness_node程序自身的account_history_plugin插件将账户交易历史保存到内存对象中，如果跟踪所有链上账户，并记录每个账户的所有交易记录，必然会造成极大的内存开销。为了保存全节点的账户交易历史，并降低节点配置要求，参考bitshares的ES插件，采用elastic_search数据库来保存所有交易记录。

插件名：elastic_search_plugin

数据库：Elastic Search

系统：Ubuntu16.04/MacOS

所需最低配置：

网络 内存 磁盘
主网 32G 1T
测试网 16G 500G

# 2. 插件的编译与启动

# 2.1 编译插件

# 1. 安装依赖

默认发布的release程序，并未包含该插件。如需使用该插件，请按照如下步骤编译带插件的witness_node程序。

安装libcurl库

sudo apt-get install libcurl4-openssl-dev
sudo apt-get install libcurl3 -y

# 2. 开启编译选项

按如下方式修改gxb-core/CMakeLists.txt文件，开启编译选项

set( LOAD_ELASTICSEARCH_PLUGIN 1)

# 3. 编译带插件的witness_node程序

在Ubuntu环境下编译：Build Ubuntu (opens new window)

在MacOS环境下编译：Build OSX (opens new window)

# 2.2 启动插件

# 1. 创建账户，使用非root账户(Ubuntu)

注：Elastic Search数据库只运行在非root账户下

sudo useradd -m myaccount -d /home/myaccount -s /bin/bash
sudo passwd myaccount

# 2. 安装java

# 1.执行
sudo apt-get update
# 2.下载jre和jdk
sudo apt-get install default-jre
sudo apt-get install default-jdk

# 3. 安装elastic_search

# 1 elasticsearch插件只能在非root账户下运行，切换到myaccount账户
su myaccount
# 2 下载安装包
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.0.zip
# 3 解压安装包
unzip elasticsearch-6.2.0.zip

提示

如果未安装unzip，请切换到root账户下安装

sudo apt-get install unzip

# 4. 配置Elastic Search数据库

修改total heap space大小

vim ./elasticsearch-6.2.0/config/jvm.options
#修改前:
-Xms1g
-Xmx1g
#修改后:
-Xms8g
-Xmx8g

# 5. 启动Elastic Search数据库

#后台模式启动
cd elasticsearch-6.2.0/
./bin/elasticsearch --daemonize

# 6. 查看Elastic Search数据库日志

tail -f ./logs/elasticsearch.log

# 7. 配置并启动全节点插件

elastic_search插件支持多项参数配置

# Elastic Search database node url(http://localhost:9200/)
# elasticsearch-node-url =

# Number of bulk documents to index on replay(10000)
# elasticsearch-bulk-replay =

# Number of bulk documents to index on a syncronied chain(100)
# elasticsearch-bulk-sync =

# Pass basic auth to elasticsearch database('')
# elasticsearch-basic-auth =

# Add a prefix to the index(gxchain)
# elasticsearch-index-prefix =

# Save operation as object(true)
# elasticsearch-operation-object =

# Start doing ES job after block(0)
# elasticsearch-start-es-after-block = 

# Maximum number of operations per account will be kept in memory
elasticsearch-max-ops-per-account = 1000

启动witness_node程序时，添加plugins参数，参数如下：

--plugins "witness elastic_search data_transaction"

# 8. 验证插件是否正常工作

默认配置情况下，在重放区块过程中，插件每5000条记录，发送到Elastic Search数据库中，可以使用如下查询语句，获取数据库中的条数。

curl -X GET 'http://localhost:9200/gxchain*/data/_count?pretty=true' -H 'Content-Type: application/json' -d '
{
	"query": {
		"bool": {
			"must": [{
				"match_all": {}
			}]
		}
	}
}
'
#返回数据，结构类似如下：
{
  "count" : 58797397,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "skipped" : 0,
    "failed" : 0
  }
}

# 3. 插件的使用说明

通过插件查询账户交易历史数据，可以通过多种类型的查询方式，查询语法参考Elastic Search数据库，查看语法 (opens new window)。

以下为一些常用查询方式，举例如下：

# 3.1 通过txid查询交易历史
