极限网关案例分享(1):使用极限网关代替 Nginx 访问 ECE
2024-12-28
背景 #
某 ECE 集群,后端 300+ 实例,最开始使用 Nginx + Keepalived 代理请求,转发到 ECE Proxy。
随着业务请求的增多,Nginx 出现异常,不能满足需求。
方案 #
进行请求代理改造,为了减少对现网环境有大的改动,设计方案如下:
- 保留当前的 Nginx + Keepalived,极限网关和 Nginx 混合部署在一台机器上面,同时借用 Keepalived 保障网关的高可用性。
- 替换用来承载业务访问的 Nginx 代理功能,由极限网关来承载外部请求,转发给后端的 ECE Proxy。
极限网关配置如下:
path.data: data
path.logs: log

- name: my_es_entry
enabled: true
router: my_router
max_concurrency: 10000
network:

配置说明:
path.data: /data
path.logs: /log
- 网关本地的存储路径,建议配置 SSD,磁盘空间在 500GB 以上。
tls:
enabled: true
cert_file: /etc/ssl.crt
key_file: /etc/ssl.key
- 泛域名证书,保持和 Nginx 一致。
- http:
schema: "https" #https or http
hosts:
- "192.168.200.209:9243"
- "192.168.200.210:9243"
- "192.168.200.211:9243"
- ECE Proxy 的访问地址。
- name: logging-server
enabled: true
endpoints:
- https://d6794e84d46e4b7db21d364de10620c4.192.168.200.209.ip.es.io:9243
basic_auth:
username: elastic
password: 1qaz!QAZ
- 记录访问日志的集群,用于分析发送给 Elasticsearch 服务器的请求。

关于极限网关(INFINI Gateway) #
INFINI Gateway 是一个面向搜索场景的高性能数据网关,所有请求都经过网关处理后再转发到后端的搜索业务集群。基于 INFINI Gateway,可以实现索引级别的限速限流、常见查询的缓存加速、查询请求的审计、查询结果的动态修改等等。
Gateway 现已开源(https://github.com/infinilabs/gateway),如有相关问题或建议,欢迎提交 PR 或 Issue,一起参与开源共建!
