ElasticSearch安裝SQL插件

ElasticSearch安裝SQL插件下載地址（中國大佬開發的，膜拜ing）：https://github.com/NLPchina/elasticsearch-sql

一、記得選擇和本身Elasticsearch對應的版本哦！若是你的是集羣默認，每一個節點都要按照這個SQL插件的哦，因爲個人是僞分佈集羣模式，個人安裝操做以下所示：

注意：安裝成功之後，是在/home/hadoop/soft/elasticsearch-5.4.3/plugins這個目錄下面的。請注意進行查收。

 1 [elsearch@slaver4 soft]$ ls
 2 elasticsearch-5.4.3  elasticsearch-head-master  el_slave  node-v8.16.2-linux-x64  nohup.out
 3 [elsearch@slaver4 soft]$ cd elasticsearch-5.4.3/
 4 [elsearch@slaver4 elasticsearch-5.4.3]$ ls
 5 bin  config  data  hs_err_pid11491.log  lib  LICENSE.txt  logs  modules  NOTICE.txt  plugins  README.textile
 6 [elsearch@slaver4 elasticsearch-5.4.3]$ ./bin/elasticsearch-plugin install https://github.com/NLPchina/elasticsearch-sql/releases/download/5.4.3.0/elasticsearch-sql-5.4.3.0.zip
 7 -> Downloading https://github.com/NLPchina/elasticsearch-sql/releases/download/5.4.3.0/elasticsearch-sql-5.4.3.0.zip
 8 [=================================================] 100%   
 9 -> Installed sql
10 [elsearch@slaver4 elasticsearch-5.4.3]$ ls
11 bin  config  data  hs_err_pid11491.log  lib  LICENSE.txt  logs  modules  NOTICE.txt  plugins  README.textile
12 [elsearch@slaver4 elasticsearch-5.4.3]$ cd plugins/
13 [elsearch@slaver4 plugins]$ ls
14 elasticsearch-analysis-ik  sql
15 [elsearch@slaver4 plugins]$ cd sql/
16 [elsearch@slaver4 sql]$ ls
17 druid.jar  elasticsearch-sql-5.4.3.0.jar  guava.jar  plugin-descriptor.properties
18 [elsearch@slaver4 sql]$ 

二、我在一個節點執行的，安裝成功之後，而後將解壓到plugins目錄下sql目錄拷貝到其餘es的節點的plugins目錄下面便可。以下所示：

 1 [elsearch@slaver4 soft]$ ls
 2 elasticsearch-5.4.3  elasticsearch-head-master  el_slave  node-v8.16.2-linux-x64  nohup.out
 3 [elsearch@slaver4 soft]$ cd elasticsearch-5.4.3/plugins/
 4 [elsearch@slaver4 plugins]$ ls
 5 elasticsearch-analysis-ik  sql
 6 [elsearch@slaver4 plugins]$ cp -r sql/ /home/hadoop/soft/el_slave/elasticsearch-5.4.3-slaver1/plugins/
 7 [elsearch@slaver4 plugins]$ cp -r sql/ /home/hadoop/soft/el_slave/elasticsearch-5.4.3-slaver2/plugins/
 8 [elsearch@slaver4 plugins]$ ls /home/hadoop/soft/el_slave/elasticsearch-5.4.3-slaver1/plugins/
 9 elasticsearch-analysis-ik  sql
10 [elsearch@slaver4 plugins]$ ls /home/hadoop/soft/el_slave/elasticsearch-5.4.3-slaver2/plugins/
11 elasticsearch-analysis-ik  sql
12 [elsearch@slaver4 plugins]$

三、若是你的僞分佈集羣啓動着呢，須要中止集羣，而後重啓集羣，查看安裝的SQL插件是否好使。

 1 [elsearch@slaver4 soft]$ ls
 2 elasticsearch-5.4.3  elasticsearch-head-master  el_slave  node-v8.16.2-linux-x64  nohup.out
 3 [elsearch@slaver4 soft]$ jps
 4 8048 Elasticsearch
 5 9428 Jps
 6 7928 Elasticsearch
 7 7998 Elasticsearch
 8 [elsearch@slaver4 soft]$ kill `ps -ef | grep Elasticsearch | grep -v grep | awk '{print $2}'`
 9 [elsearch@slaver4 soft]$ jps
10 9480 Jps
11 [elsearch@slaver4 soft]$ cd elasticsearch-5.4.3/
12 [elsearch@slaver4 elasticsearch-5.4.3]$ ls
13 bin  config  data  hs_err_pid11491.log  lib  LICENSE.txt  logs  modules  NOTICE.txt  plugins  README.textile
14 [elsearch@slaver4 elasticsearch-5.4.3]$ cd bin/
15 [elsearch@slaver4 bin]$ ls
16 elasticsearch         elasticsearch.in.sh         elasticsearch-plugin       elasticsearch-service-mgr.exe  elasticsearch-systemd-pre-exec  hs_err_pid9127.log

18 elasticsearch.in.bat  elasticsearch-keystore.bat  elasticsearch-service.bat  elasticsearch-service-x86.exe  elasticsearch-translog.bat
19 [elsearch@slaver4 bin]$ ./elasticsearch -d
20 [elsearch@slaver4 bin]$ cd ../../el_slave/
21 [elsearch@slaver4 el_slave]$ ls
22 elasticsearch-5.4.3-slaver1  elasticsearch-5.4.3-slaver2
23 [elsearch@slaver4 el_slave]$ cd elasticsearch-5.4.3-slaver1/
24 [elsearch@slaver4 elasticsearch-5.4.3-slaver1]$ ls
25 bin  config  data  hs_err_pid11491.log  lib  LICENSE.txt  logs  modules  NOTICE.txt  plugins  README.textile
26 [elsearch@slaver4 elasticsearch-5.4.3-slaver1]$ cd bin/
27 [elsearch@slaver4 bin]$ ls
28 elasticsearch         elasticsearch.in.sh         elasticsearch-plugin       elasticsearch-service-mgr.exe  elasticsearch-systemd-pre-exec
29 elasticsearch.bat     elasticsearch-keystore      elasticsearch-plugin.bat   elasticsearch-service-x64.exe  elasticsearch-translog
30 elasticsearch.in.bat  elasticsearch-keystore.bat  elasticsearch-service.bat  elasticsearch-service-x86.exe  elasticsearch-translog.bat
31 [elsearch@slaver4 bin]$ ./elasticsearch -d
32 [elsearch@slaver4 bin]$ cd ../../elasticsearch-5.4.3-slaver2/
33 [elsearch@slaver4 elasticsearch-5.4.3-slaver2]$ ls
34 bin  config  data  hs_err_pid11491.log  lib  LICENSE.txt  logs  modules  NOTICE.txt  plugins  README.textile
35 [elsearch@slaver4 elasticsearch-5.4.3-slaver2]$ cd bin/
36 [elsearch@slaver4 bin]$ ls
37 elasticsearch         elasticsearch.in.sh         elasticsearch-plugin       elasticsearch-service-mgr.exe  elasticsearch-systemd-pre-exec
38 elasticsearch.bat     elasticsearch-keystore      elasticsearch-plugin.bat   elasticsearch-service-x64.exe  elasticsearch-translog
39 elasticsearch.in.bat  elasticsearch-keystore.bat  elasticsearch-service.bat  elasticsearch-service-x86.exe  elasticsearch-translog.bat
40 [elsearch@slaver4 bin]$ ./elasticsearch -d
41 [elsearch@slaver4 bin]$ jps
42 9520 Elasticsearch
43 9651 Jps
44 9637 Elasticsearch
45 9578 Elasticsearch
46 [elsearch@slaver4 bin]$ 

四、此時，你就可使用瀏覽器進行測試，http://192.168.110.133:9200/_sql?sql=select * from player limit 10，個人測試以下所示：

注意：from後面跟的是你的索引Index哦！別查詢錯誤了。

五、而後你可使用界面的形式寫SQL，感受很喜歡這種方式哦！下載SQL的Server，方式以下所示：

注意：下面這個插件使用的是node編寫的，因此須要node相關的依賴包，以前弄過，這裏省略了。在一臺節點安裝便可哦！

開始執行解壓縮操做，命令以下所示：

注意：因爲unzip是解壓縮到當前目錄，你能夠將.zip的包刪除掉。

 1 [elsearch@slaver4 hadoop]$ cd soft/
 2 [elsearch@slaver4 soft]$ ls
 3 elasticsearch-5.4.3  elasticsearch-head-master  el_slave  node-v8.16.2-linux-x64  nohup.out
 4 [elsearch@slaver4 soft]$ mkdir el_sql
 5 [elsearch@slaver4 soft]$ cp ../es-sql-site-standalone.zip ./el_sql/
 6 [elsearch@slaver4 soft]$ ls
 7 elasticsearch-5.4.3  elasticsearch-head-master  el_slave  el_sql  node-v8.16.2-linux-x64  nohup.out
 8 [elsearch@slaver4 soft]$ cd el_sql/
 9 [elsearch@slaver4 el_sql]$ ls
10 es-sql-site-standalone.zip
11 [elsearch@slaver4 el_sql]$ unzip es-sql-site-standalone.zip 

六、開始安裝你的圖形化插件，以下所示：

 1 [elsearch@slaver4 el_sql]$ cd site-server/
 2 [elsearch@slaver4 site-server]$ ls
 3 node-server.js  package.json  site_configuration.json
 4 [elsearch@slaver4 site-server]$ npm install express --save
 5 npm notice created a lockfile as package-lock.json. You should commit this file.
 6 npm WARN site-server No description
 7 npm WARN site-server No repository field.
 8 npm WARN site-server No license field.
 9 
10 + express@4.17.1
11 added 50 packages from 37 contributors and audited 126 packages in 19.057s
12 found 0 vulnerabilities
13 
14 [elsearch@slaver4 site-server]$ 

七、修改SQL的Server的端口，vi site_configuration.json。默認端口號是8080，若是沒有佔用的話，能夠直接使用的。操做以下所示：

1 [elsearch@slaver4 site-server]$ vim site_configuration.json

八、安裝成功之後啓動你的服務，以下所示：

前臺啓動方式以下所示：node node-server.js

後臺啓動方式以下所示：node node-server.js &

1 [elsearch@slaver4 site-server]$ node node-server.js

九、啓動成功之後能夠查看界面，以下所示：

十、圖形化界面使用以下所示：

注意：記得修改右上角的地址哦！
