Nginx代理Redis哨兵主从配置怎么实现

一、环境

nginx版本：1.21.6
center7.5及以上或mas os
搭建redis哨兵主从模式
springboot集成redis哨兵主从模式

提示：Nginx必须安装upstream模块

二、配置

Nginx配置有三个方案（详见后续内容），其中：方案一将哨兵所有节点使用一个端口对外映射；方案二是每个哨兵端口配置一个对应的映射端口，总体和正常哨兵配置方式无差别；方案三其实就是方案一和方案二的结合体。个人认为其意义不大，有兴趣的小伙伴可以自行尝试。

2.1、方案一（推荐）

# stream模块配置和http模块在相同级别
stream {
    upstream redis {
        server 127.0.0.1:26379 max_fails=3 fail_timeout=10s;
        server 127.0.0.1:26380 max_fails=3 fail_timeout=10s;
        server 127.0.0.1:26381 max_fails=3 fail_timeout=10s;
    }
    server {
        listen 5432;
        proxy_connect_timeout 30s;
        proxy_timeout 60s;
        proxy_pass redis;
    }
}

2.2、方案二

# stream模块配置和http模块在相同级别
stream {
    upstream redis {
        server 127.0.0.1:26379 max_fails=3 fail_timeout=10s;
    }
    upstream redis1 {
        server 127.0.0.1:26380 max_fails=3 fail_timeout=10s;
    }
    upstream redis2 {
        server 127.0.0.1:26381 max_fails=3 fail_timeout=10s;
    }
    server {
        listen 5432;
        proxy_connect_timeout 30s;
        proxy_timeout 60s;
        proxy_pass redis;
    }
    server {
        listen 5433;
        proxy_connect_timeout 30s;
        proxy_timeout 60s;
        proxy_pass redis1;
    }
    server {
        listen 5434;
        proxy_connect_timeout 30s;
        proxy_timeout 60s;
        proxy_pass redis2;
    }
}

2.3、方案三

# stream模块配置和http模块在相同级别
stream {
    upstream redis {
        server 127.0.0.1:26379 max_fails=3 fail_timeout=10s;
        server 127.0.0.1:26380 max_fails=3 fail_timeout=10s;
        server 127.0.0.1:26381 max_fails=3 fail_timeout=10s;
    }
    upstream redis1 {
        server 127.0.0.1:26380 max_fails=3 fail_timeout=10s;
        server 127.0.0.1:26379 max_fails=3 fail_timeout=10s;
        server 127.0.0.1:26381 max_fails=3 fail_timeout=10s;
    }
    upstream redis2 {
        server 127.0.0.1:26381 max_fails=3 fail_timeout=10s;
        server 127.0.0.1:26380 max_fails=3 fail_timeout=10s;
        server 127.0.0.1:26379 max_fails=3 fail_timeout=10s;
    }
    server {
        listen 5432;
        proxy_connect_timeout 30s;
        proxy_timeout 60s;
        proxy_pass redis;
    }
    server {
        listen 5433;
        proxy_connect_timeout 30s;
        proxy_timeout 60s;
        proxy_pass redis1;
    }
    server {
        listen 5434;
        proxy_connect_timeout 30s;
        proxy_timeout 60s;
        proxy_pass redis2;
    }
}
