2019-09-02我想问下使用nginx负载到es集群，用于数据写入是否可行，比如前端，客户端的指标数据上送，就不需要单独开发应用去做中间转换。直接使用es的api进行写入。可是我又怕这样会有安全问题和性能问题，老师有没有好点的建议？作者回复: ngix用来做软件的负载均衡是没有问题的。身份认证也可以通过nginx来实现，只是实现rbac会相对复杂，而且也最多只能做到index级别

作者回复: 直接用带https的endpoint
- 2019-10-15$ ./bin/elasticsearch-setup-passwords interactive
SSL connection to https://192.168.56.131:9200/_security/_authenticate?pretty failed: No subject alternative names present
Please check the elasticsearch SSL settings under xpack.security.http.ssl.
ERROR: Failed to establish SSL connection to elasticsearch at https://192.168.56.131:9200/_security/_authenticate?pretty.
执行设置用户密码报错这时什么问题
这时配置

2019-09-22设置只能通过https进行安全加密的对外数据传输，没做过ES的运维工作，先知道她是怎么玩的。- 2019-09-06生产环境如果要避免错误提示问题，需要购买收费证书么？
作者回复: 对
