按照之前的四篇文章,走到现在,接下来就是需要安装jdbc了。这里是用的是jdbc的2.3.4.0版本,虽然按照官方给出的对应版本对应不上,https://github.com/jprante/elasticsearch-jdbc,但是实际测试,是可以支持的。
下载解压并移动到/usr/local/jdbc目录
#wget http://xbib.org/repository/org/xbib/elasticsearch/importer/elasticsearch-jdbc/2.3.4.0/elasticsearch-jdbc-2.3.4.0-dist.zip //wget下载地址
# unzip elasticsearch-jdbc-2.3.4.0-dist.zip
# mv elasticsearch-jdbc-2.3.4.0-dist.zip /usr/local/jdbc/
配置环境变量
# vim /etc/profile //把下面两行代码放入底部
export JDBC_HOME=/usr/local/jdbc
export ES_HOME=/usr/local/elasticsearch
# source /etc/profile //生效
接下来创建导入脚本
# cd /usr/local/
# mkdir shell shell/logs
# vim mysql-elasticsearch.sh
#脚本内容
#!/bin/sh
bin=$JDBC_HOME/bin
lib=$JDBC_HOME/lib
echo '{
"type" : "jdbc",
"jdbc": {
"elasticsearch.autodiscover":true,
"elasticsearch.cluster":"my-application", #簇名,对应好配置
"url":"jdbc:mysql://192.168.9.155:3306/hb", #mysql地址/端口/库名
"user":"root", #Mysql账号
"password":"wt000000", #Mysql密码
"sql":"select product_name,id as _id from hp_product where id >10 limit 10 ", #SQL语句 .........注意的是,这里只是测试,在实际配置中需要对应好要存入文档的字段,同样表的主见id对应文档id
"elasticsearch" : { "cluster":"my-application",
"host" : "192.168.9.155",
"port" : 9300
},
"index" : "myindex", #新的index,这里测试的是商品表,用的index是myindex,其实可以规范命名~
"type" : "mytype" #新的type,类型也可以规范命名
}
}'| java \
-cp "${lib}/*" \
-Dlog4j.configurationFile=${bin}/log4j2.xml \
org.xbib.tools.Runner \
org.xbib.tools.JDBCImporter
# chmod a+x mysql-elasticsearch.sh //赋予权限
# ./mysql-elasticsearch.sh //执行脚本
执行完成之后,查看一下日志文件,[INFO]成功信息~
cat /usr/local/shell/logs/jdbc.log
# curl -XGET 'http://192.168.9.155:9200/myindex/mytype/_search?pretty'
