Nginx代理Redis哨兵主從配置

一、環境

Nginx版本：1.21.6
Center7.5及以上或Mas OS
搭建Redis哨兵主從模式
Springboot集成Redis哨兵主從模式

• 提示：Nginx必須安裝upstream模塊

二、配置

Nginx配置有三個方案（詳見后續內容），其中：方案一將哨兵所有節點使用一個端口對外映射；方案二是每個哨兵端口配置一個對應的映射端口，總體和正常哨兵配置方式無差別；方案三其實就是方案一和方案二的結合體。個人認為其意義不大，有興趣的小伙伴可以自行嘗試。

2.1、方案一（推薦）

# stream模塊配置和http模塊在相同級別
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模塊配置和http模塊在相同級別
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模塊配置和http模塊在相同級別
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;
    }
}
