按照之前的四篇文章,走到現在,接下來就是需要安裝jdbc了。這裡是用的是jdbc的2.3.4.0版本,雖然按照官方給出的對應版本對應不上,https://github.com/jprante/elasticsearch-jdbc,但是實際測試,是可以支援的。
下載解壓並移動到/usr/local/jdbc目錄
#wget http://xbib.org/repository/org/xbib/elasticsearch/importer/elasticsearch-jdbc/2.3.4.0/elasticsearch-jdbc-2.3.4.0-dist.zip //wget下載地址
# unzip elasticsearch-jdbc-2.3.4.0-dist.zip
# mv elasticsearch-jdbc-2.3.4.0-dist.zip /usr/local/jdbc/
配置環境變數
# vim /etc/profile //把下面兩行程式碼放入底部
export JDBC_HOME=/usr/local/jdbc
export ES_HOME=/usr/local/elasticsearch
# source /etc/profile //生效
接下來建立匯入指令碼
# cd /usr/local/
# mkdir shell shell/logs
# vim mysql-elasticsearch.sh
#指令碼內容
#!/bin/sh
bin=$JDBC_HOME/bin
lib=$JDBC_HOME/lib
echo '{
"type" : "jdbc",
"jdbc": {
"elasticsearch.autodiscover":true,
"elasticsearch.cluster":"my-application", #簇名,對應好配置
"url":"jdbc:mysql://192.168.9.155:3306/hb", #mysql地址/埠/庫名
"user":"root", #Mysql賬號
"password":"wt000000", #Mysql密碼
"sql":"select product_name,id as _id from hp_product where id >10 limit 10 ", #SQL語句 .........注意的是,這裡只是測試,在實際配置中需要對應好要存入文件的欄位,同樣表的主見id對應文件id
"elasticsearch" : {
"cluster":"my-application",
"host" : "192.168.9.155",
"port" : 9300
},
"index" : "myindex", #新的index,這裡測試的是商品表,用的index是myindex,其實可以規範命名~
"type" : "mytype" #新的type,型別也可以規範命名
}
}'| java \
-cp "${lib}/*" \
-Dlog4j.configurationFile=${bin}/log4j2.xml \
org.xbib.tools.Runner \
org.xbib.tools.JDBCImporter
# chmod a+x mysql-elasticsearch.sh //賦予許可權
# ./mysql-elasticsearch.sh //執行指令碼
執行完成之後,檢視一下日誌檔案,[INFO]成功資訊~
cat /usr/local/shell/logs/jdbc.log
# curl -XGET 'http://192.168.9.155:9200/myindex/mytype/_search?pretty'

通過命令檢視es中資料
curl -XGET 'http://XXX.XXX.XXX.XXX:9200/knowledge_index/knowledge/_search?pretty'
刪除指定索引
# curl -XDELETE 'http://172.16.170.122:9200/index_name'
