21-win10下ElasticSearch.6.1.0安装SQL插件

简介：win10下ElasticSearch.6.1.0安装SQL插件

5.安装sql

5.0 es配置

安装es http://blog.csdn.net/qq_21383435/article/details/79275543

cluster.name: elasticsearch
node.name: "lcc_node"
node.master: true
# 指定该节点是否存储索引数据，默认为true。
node.data: true

# 设置默认索引分片个数，默认为5片。
#index.number_of_shards: 1

# 设置默认索引副本个数，默认为1个副本。如果采用默认设置，而你集群只配置了一台机器，
# 那么集群的健康度为yellow，也就是所有的数据都是可用的，但是某些复制没有被分配
#index.number_of_replicas: 1

# 设置配置文件的存储路径，默认是es根目录下的config文件夹。
#path.conf: J:\elasticsearch\elasticsearch-6.2.1\config

# 设置索引数据的存储路径，默认是es根目录下的data文件夹，可以设置多个存储路径，用逗号隔开
#path.data: J:\elasticsearch\elasticsearch-6.2.1\data

# 设置临时文件的存储路径，默认是es根目录下的work文件夹。
#path.work: J:\elasticsearch\elasticsearch-6.2.1\worker

# 设置日志文件的存储路径，默认是es根目录下的logs文件夹
# path.logs: /path/to/logs

# 设置为true来锁住内存不进行swapping。因为当jvm开始swapping时es的效率 会降低，
# 所以要保证它不swap，可以把ES_MIN_MEM和ES_MAX_MEM两个环境变量设置成同一个值，
# 并且保证机器有足够的内存分配给es。 同时也要允许elasticsearch的进程可以锁住内存，
# linux下启动es之前可以通过`ulimit -l unlimited`命令设置。
# bootstrap.mlockall: true

network.host: 127.0.0.1
http.port: 9200

http.cors.enabled: true
http.cors.allow-origin: "*"

action.auto_create_index : .security,.monitoring*,.watches,.triggered_watches,.watcher-history*
#xpack.security.enabled : false
#xpack.monitoring.enabled : true
#xpack.graph.enabled : false
#xpack.watcher.enabled : false
#xpack.ml.enabled : false


# 单个命令来删除所有数据可能会导致可怕的后果。这个设置使删除只限于特定名称指向的数据, 而不允许通过指定 _all 或通配符来删除指定索引库。
action.destructive_requires_name: true

#index.number_of_replicas: 0
#cluster.routing.allocation.enable : all

5.1 解决方法：命令安装(未成功)

J:\elasticsearch\elasticsearch-6.1.0\bin>elasticsearch-plugin  -u https://github.com/NLPchina/elasticsearch-sql/releases/download/1.4.7/elasticsearch-sql-1.4.7.zip --install sql

5.2 解决方法：直接下载(未成功)

直接下载解压J:\elasticsearch\elasticsearch-6.1.0\plugins\sql

运行保持报错
J:\elasticsearch\elasticsearch-6.1.0\bin>elasticsearch.bat
[2018-02-28T22:36:51,531][WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [lcc_node] uncaught exception in thread [main]

Caused by: java.nio.file.NoSuchFileException: J:\elasticsearch\elasticsearch-6.1.0\plugins\sql\plugin-descriptor.properties

再次命令运行

J:\elasticsearch\elasticsearch-6.1.0\bin>elasticsearch-plugin install https://github.com/NLPchina/elasticsearch-sql/releases/download/6.1.0.0/elasticsearch-sql-6.1.0.0.zip

Exception in thread "main" java.net.ConnectException: Connection timed out: connect

Caused by: java.net.ConnectException: Connection timed out: connect

5.3 解决方法：直接下载(未成功)

然后我尝试下载一个包elasticsearch-sql-elastic6.1.0.zip 放到目录J:\elasticsearch\elasticsearch-6.1.0\plugins\elasticsearch-sql-elastic6.1.0.zip 下，继续执行安装命令，结果如下

J:\elasticsearch\elasticsearch-6.1.0\bin>elasticsearch-plugin install https://github.com/NLPchina/elasticsearch-sql/releases/download/6.1.0.0/elasticsearch-sql-6.1.0.0.zip
-> Downloading https://github.com/NLPchina/elasticsearch-sql/releases/download/6.1.0.0/elasticsearch-sql-6.1.0.0.zip

5.4 解决方法：下载后编译(未成功)

J:\elasticsearch\elasticsearch-6.1.0\plugins\sql>mvn package

5.5 解决方法：命令安装(成功)

网友说，6.2.0的没有这个插件，然后，让我修改成6.1.0的，结果还是不对
最后查询
https://github.com/NLPchina/elasticsearch-sql/issues/610

https://github.com/NLPchina/elasticsearch-sql/issues/615

Exception:Unknown properties in plugin descriptor: [jvm, site] since 6.1.3 #615

First thank you for a great work

The plugin don't work since 6.1.3   es-sql从6.1.3后开始就不工作了

And can you please update to 6.2.2  请更新到6.2.2

但是更新到6.2.2后，发现https://github.com/NLPchina/elasticsearch-sql（这个网页有安装命令，往下拉）现在最大的es-sql版本为6.1.0，还没更新出来6.2.2

所以我使用了es6.1.0去尝试

D:\elasticsearch\elasticsearch-6.1.0\bin>elasticsearch-plugin install https://github.com/NLPchina/elasticsearch-sql/releases/download/6.1.0.0/elasticsearch-sql-6.1.0.0.zip
-> Downloading https://github.com/NLPchina/elasticsearch-sql/releases/download/6.1.0.0/elasticsearch-sql-6.1.0.0.zip
[=================================================] 100%??
-> Installed sql

D:\elasticsearch\elasticsearch-6.1.0\bin>

然后在D:\elasticsearch\elasticsearch-6.1.0\plugins目录下有个sql文件夹

然后事实证明，最新不一定最好

启动出现，下面一句话就对了

D:\elasticsearch\elasticsearch-6.1.0\bin>elasticsearch.bat
[2018-03-01T13:46:34,606][INFO ][o.e.p.PluginsService     ] [node-120.0.0銆?] loaded plugin [sql]

执行这个命令，可能报错

2018-03-01 21:42:03,406 main ERROR Could not register mbeans java.security.AccessControlException: access denied ("javax.management.MBeanTrustPermission" "register")
        at java.security.AccessControlContext.checkPermission(AccessControlContext.java:472)
        at java.lang.SecurityManager.checkPermission(SecurityManager.java:585)

这个是权限问题，因为不是linux系统，所以这里暂时不管，我也没找到解决方法

但是我的最后访问http://localhost:9200/_plugin/sql/ 居然没反应
看官方文档
https://github.com/NLPchina/elasticsearch-sql
发现

Basic Usage
On elasticsearch 1.x / 2.x, visit the elasticsearch-sql web front-end:

http://localhost:9200/_plugin/sql/

On elasticsearch 5.x/6.x, download and extract site.

Then start the web front-end like this:

cd site-server
npm install express --save
node node-server.js 

然后我去下载download and extract site.这几个字对应的包，然后解压

执行命令

D:\elasticsearch\es-sql-site-standalone\site-server>npm install express --save
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN site-server No description
npm WARN site-server No repository field.
npm WARN site-server No license field.

+ express@4.16.2
added 49 packages in 17.728s

D:\elasticsearch\es-sql-site-standalone\site-server>node node-server.js

访问

es的head如下http://localhost:9100/

使用查询语句

http://localhost:9200/_sql?sql=select * from indexName limit 10

但是我新建一个索引

PUT /megacorp
{
  "settings":{
           "number_of_shards":1,     
           "number_of_replicas":0
  }
}


POST /megacorp/employee/1
{
    "first_name" : "John",
    "last_name" :  "Smith",
    "age" :        25,
    "about" :      "I love to go rock climbing",
    "interests": [ "sports", "music" ]
}

再次查询
