一、linux上使用
前提:
1)elasticsearch 2.3.2 安装成功,测试ok。
2)mysql安装成功,能实现增、删、改、查。
可供测试的数据库为test,表为cc,具体信息如下:
mysql> select * from cc;
+----+------------+
| id | name |
+----+------------+
| 1 | laoyang |
| 2 | dluzhang |
| 3 | dlulaoyang |
+----+------------+
3 rows in set (0.00 sec)
第一步:下载工具。
址:http://xbib.org/repository/org/xbib/elasticsearch/importer/elasticsearch-jdbc/2.3.2.0/elasticsearch-jdbc-2.3.2.0-dist.zip
第二步:导入Centos。路径自己定,笔者放到根目录下,解压。unzip elasticsearch-jdbc-2.3.2.0-dist.zip
第三步:设置环境变量。
[root@5b9dbaaa148a /]# vi /etc/profile
export JDBC_IMPORTER_HOME=/elasticsearch-jdbc-2.3.2.0
使环境变量生效:
[root@5b9dbaaa148a /]# source /etc/profile
第四步:配置使用。详细参考:https://github.com/jprante/elasticsearch-jdbc
1)、根目录下新建文件夹odbc_es 如下:
[root@5b9dbaaa148a /]# ll /odbc_es/
drwxr-xr-x 2 root root 4096 Jun 16 03:11 logs
-rwxrwxrwx 1 root root 542 Jun 16 04:03 mysql_import_es.sh
2)、新建脚本mysql_import_es.sh,内容如下;
[root@5b9dbaaa148a odbc_es]# cat mysql_import_es.sh
’#!/bin/sh
bin=$JDBC_IMPORTER_HOME/bin
lib=$JDBC_IMPORTER_HOME/lib
echo '{
"type" : "jdbc",
"jdbc": {
"elasticsearch.autodiscover":true,
"elasticsearch.cluster":"my-application", #簇名,详见:/usr/local/elasticsearch/config/elasticsearch.yml
"url":"jdbc:mysql://10.8.5.101:3306/test", #mysql数据库地址
"user":"root", #mysql用户名
"password":"123456", #mysql密码
"sql":"select * from cc",
"elasticsearch" : {
"host" : "10.8.5.101",
"port" : 9300
},
"index" : "myindex", #新的index
"type" : "mytype" #新的type
}
}'| java \
-cp "${lib}/*" \
-Dlog4j.configurationFile=${bin}/log4j2.xml \
org.xbib.tools.Runner \
org.xbib.tools.JDBCImporter
3)、为 mysql_import_es.sh 添加可执行权限。
[root@5b9dbaaa148a odbc_es]# chmod a+x mysql_import_es.sh
4)执行脚本mysql_import_es.sh
[root@5b9dbaaa148a odbc_es]# ./mysql_import_es.sh
第五步:测试数据同步是否成功。
使用elasticsearch检索查询:
[root@5b9dbaaa148a odbc_es]# curl -XGET 'http://10.8.5.101:9200/myindex/mytype/_search?pretty'
{
"took" : 4,
"timed_out" : false,
"_shards" : {
"total" : 8,
"successful" : 8,
"failed" : 0
},
"hits" : {
"total" : 3,
"max_score" : 1.0,
"hits" : [ {
"_index" : "myindex",
"_type" : "mytype",
"_id" : "AVVXKgeEun6ksbtikOWH",
"_score" : 1.0,
"_source" : {
"id" : 1,
"name" : "laoyang"
}
}, {
"_index" : "myindex",
"_type" : "mytype",
"_id" : "AVVXKgeEun6ksbtikOWI",
"_score" : 1.0,
"_source" : {
"id" : 2,
"name" : "dluzhang"
}
}, {
"_index" : "myindex",
"_type" : "mytype",
"_id" : "AVVXKgeEun6ksbtikOWJ",
"_score" : 1.0,
"_source" : {
"id" : 3,
"name" : "dlulaoyang"
}
} ]
}
}
出现以上包含mysql数据字段的信息则为同步成功。
[root@5b9dbaaa148a odbc_es]# cat mysql_import_es_simple.sh
#!/bin/sh
bin=$JDBC_IMPORTER_HOME/bin
lib=$JDBC_IMPORTER_HOME/lib
java \
-cp "${lib}/*" \
-Dlog4j.configurationFile=${bin}/log4j2.xml \
org.xbib.tools.Runner \
org.xbib.tools.JDBCImporter statefile.json
[root@5b9dbaaa148a odbc_es]# cat statefile.json
{
"type" : "jdbc",
"jdbc": {
"elasticsearch.autodiscover":true,
"elasticsearch.cluster":"my-application",
"url":"jdbc:mysql://10.8.5.101:3306/test",
"user":"root",
"password":"123456",
"sql":"select * from cc",
"elasticsearch" : {
"host" : "10.8.5.101",
"port" : 9300
},
"index" : "myindex_2",
"type" : "mytype_2"
}
}
脚本和json文件分开,脚本执行前先加载json文件。
执行方式:直接运行脚本 ./mysql_import_es_simple.sh 即可。
目标:实现从表cc中查询id=3的name信息。
1)MySQL中sql语句查询:
mysql> select * from cc where id=3;
+----+------------+
| id | name |
+----+------------+
| 3 | dlulaoyang |
+----+------------+
1 row in set (0.00 sec)
2)elasticsearch检索:
[root@5b9dbaaa148a odbc_es]# curl http://10.8.5.101:9200/myindex/mytype/_search?pretty -d '
{
"filter" : { "term" : { "id" : "3" } }
}'
{
"took" : 3,
"timed_out" : false,
"_shards" : {
"total" : 8,
"successful" : 8,
"failed" : 0
},
"hits" : {
"total" : 1,
"max_score" : 1.0,
"hits" : [ {
"_index" : "myindex",
"_type" : "mytype",
"_id" : "AVVXKgeEun6ksbtikOWJ",
"_score" : 1.0,
"_source" : {
"id" : 3,
"name" : "dlulaoyang"
}
} ]
}
}
二、windoes上使用
脚本配置:
@echo off
set LIB=%JDBC_IMPORTER_HOME%\lib\*
set BIN=%JDBC_IMPORTER_HOME%\bin
echo {^
"type" : "jdbc",^
"jdbc" : {^
"url" : "jdbc:mysql://localhost:3306/test",^
"user" : "root",^
"password" : "esri",^
"sql" : "select * from mysql2es_test",^
"treat_binary_as_string" : true,^
"elasticsearch" : {^
"cluster" : "application",^
"host" : "localhost",^
"port" : 9300^
},^
"index" : "test"^
}^
}^ | "%JAVA_HOME%\bin\java" -cp "%LIB%" -Dlog4j.configurationFile="%BIN%\log4j2.xml" "org.xbib.tools.Runner" "org.xbib.tools.JDBCImporter"
