ElasticSearch报错记录

注册服务后启动报错

Missing service ImageFile错误

安装的时候一定需要按照顺序安装，先安装JDK，配置好JAVA_HOME，然后再使用elasticsearch-service.bat install进行服务安装

elasticsearch-head 连不上ES

通过修改config/elasticsearch.yml，在最后面加上下面两行信息，文章最后附上完整的yml文件
http.cors.enabled: true
http.cors.allow-origin: “*”
再次启动elasticsearch即可

安装IK之后服务无法启动

Plugin [analysis-ik] was built for Elasticsearch version 7.6.2 but version 7.6.1 is running
原因：我的ES是7.6.1版本，但是ik是7.6.2版本
ik下载：ik下载.

提示access denied

原因分析：安装目录中不能存在空格

filebeat出现 Non-zero metrics in the last 30s

将input和output设置enabled: true

filebeat指定索引之后无效，还是新增默认索引

增加配置：setup.ilm.enabled: false

filebeat上传数据定义mapping

1.在ES创建template
2.生成的文件每行一个json串
3.新增如下配置
