一、数据从文件导入elasticsearch
1、数据准备：
1、数据文件：test.json 2、索引名称：index 3、数据类型：doc 4、批量操作API：bulk
{"index":{"_index":"index2","_type":"type2","_id":0}}
{"age":10,"name":"jim"}
{"index":{"_index":"index2","_type":"type2","_id":1}}
{"age":16,"name":"tom"}
2、_bulk API导入ES的JSON文件需要满足一定的格式，每条记录之前，需要有文档ID且每一行\n结束
curl -H ‘Content-Type: application/x-ndjson‘ -s -XPOST localhost:9200/_bulk --data-binary @test.json
如果是在test.json文件中没有指定index名、type、id时：
curl -H ‘Content-Type: application/x-ndjson‘ -s -XPOST localhost:9200/index2/type2/_bulk --data-binary @test.json
{ "index" : { } }
{"age":16,"name":"tom"}
但是id会自动生成
3、对于普通json文件的导入，可以logstash进行导入：
logstash的安装准备详细过程请查阅：
https://www.cnblogs.com/yfb918/p/10763292.html
json数据准备
[root@master mnt]# cat data.json
{"age":16,"name":"tom"}
{"age":11,"name":"tsd"}
创建配置文件：
[root@master bin]# cat json.conf
input{
file{
path=>"/mnt/data.json"
start_position=>"beginning"
sincedb_path=>"/dev/null"
codec=>json{
charset=>"ISO-8859-1"
}
}
}
output{
elasticsearch{
hosts=>"http://192.168.200.100:9200"
index=>"jsontestlogstash"
document_type=>"doc"
}
stdout{}
}
执行结果：
[root@master bin]# ./logstash -f json.conf
[2019-04-25T10:59:14,803][INFO ][logstash.agent ] Pipelines running {:count=>1, :running_pipelines=>[:main], :non_running_pipelines=>[]}
[2019-04-25T10:59:16,084][INFO ][logstash.agent ] Successfully started Logstash API endpoint {:port=>9600}
{
"name" => "tom",
"age" => 16,
"path" => "/mnt/data.json",
"@timestamp" => 2019-04-25T02:59:16.009Z,
"host" => "master",
"@version" => "1"
}
{
"name" => "tsd",
"age" => 11,
"path" => "/mnt/data.json",
"@timestamp" => 2019-04-25T02:59:16.096Z,
"host" => "master",
"@version" => "1"
}
从结果中可以看到：默认增加了几个字段。那么我们想要这几个默认生成的字段我们应该怎么么办呢，可以如下解决：
在配置文件中使用filter进行过滤：
[root@master bin]# cat json.conf
input{
file{
path=>"/mnt/data.json"
start_position=>"beginning"
sincedb_path=>"/dev/null"
codec=>json{
charset=>"ISO-8859-1"
}
}
}
filter{
mutate {
remove_field => "@timestamp"
remove_field => "@version"
remove_field => "host"
remove_field => "path"
}
}
output{
elasticsearch{
hosts=>"http://192.168.200.100:9200"
index=>"jsontestlogstash"
document_type=>"doc"
}
stdout{}
}
过滤之后的结果：
