nacos-elasticsearch

这是一个elasticsearch的插件,实现将当前节点的http访问点注册到nacos,以便其他基于nacos注册中心的微服务得以访问elasticsearch。

欢迎提交PR和Issue

插件主要依赖nacos-client实现:

  • 注册服务
  • 保持服务心跳
  • 周期性刷新nacos服务器列表

编译

mvn package

安装

将构建的target/nacos-elasticsearch-xx.zip包解压到每个es节点的plugins目录,将外层文件夹重命名为nacos-elasticsearch(注意权限),最终目录结构如下:

也可以用elasticsearch-plugin命令直接安装zip

plugins
|--nacos-elasticsearch
    |--nacos-elasticsearch-1.0.0.jar
    |--plugin-descriptor.properties
    |--plugin-security.policy
    |--....

配置每个es节点,增加nacos相关配置项,并重启每个es节点,注意节点是否能正常启动。如果一切顺利,在nacos管理界面可以查看到elasticsearch的服务和实例。

当前构建的插件包,默认支持7.1.1的elasticsearch,如果需要适配其他版本,可以自行修改plugin-descriptor.properties 但也有可能因为jar包冲突等问题,无法适配elasticsearch

配置

为每个elasticsearch增加了如下配置:

key required default value description
nacos.register.enabled false false 是否启动nacos自动注册功能,默认不开启
nacos.server.addrs true nacos服务ip:port组成的list
nacos.server.user false nacos登录用户名,如果nacos开启安全验证,则需要配置
nacos.server.password false nacos登录密码,如果nacos开启安全验证,则需要配置
nacos.node.weight false 1.0 nacos节点权重, 0权重表示不可访问
nacos.service.namespace false public 命名空间
nacos.service.name false elasticsearch 配置当前es集群注册到nacos的服务名,默认服务名就是elasticsearch
nacos.beat.interval false 10s 保持心跳的上报周期
nacos.refresh.interval false 30s 刷新nacos服务列表的周期

要开启插件功能,至少配置nacos.register.enabled: truenacos.server.addr

使用keystore安全地存储密码

支持通过elasticseach-keystore将密码加密配置:

bin/elasticsearch-keystore add nacos.server.password.keystore
Enter value for nacos.server.password.keystore: 

插件会优先读取keystore中读取nacos.server.password.keystore的值作为密码,如果没有密码,则从elasicsearch.yml中尝试读取nacos.server.password
