# Nginx 负载均衡 - 加权轮询配置示例
|
||
# ============================================================
|
||
#
|
||
# 功能说明:
|
||
# - 按权重分配请求比例
|
||
# - 适用于服务器性能差异场景
|
||
# - 权重越大，分配请求越多
|
||
#
|
||
# Lolly 对应配置:
|
||
# server:
|
||
# proxy:
|
||
# - path: "/api"
|
||
# targets:
|
||
# - url: "http://backend1:8080"
|
||
# weight: 5
|
||
# - url: "http://backend2:8080"
|
||
# weight: 3
|
||
# - url: "http://backend3:8080"
|
||
# weight: 2
|
||
# load_balance: "weighted_round_robin"
|
||
# ============================================================
|

|
||
upstream backend {
|
||
# 加权轮询
|
||
# Lolly 对应: load_balance: "weighted_round_robin"，每个 target 设置 weight
|
||
|
||
# 权重比例 5:3:2 = backend1 处理 50% 请求
|
||
server backend1:8080 weight=5;
|
||
server backend2:8080 weight=3;
|
||
server backend3:8080 weight=2;
|
||
|
||
# 备用服务器（权重为 0，仅在主服务器故障时启用）
|
||
server backend4:8080 backup;
|
||
|
||
keepalive 32;
|
||
}
|

|

server {
|

listen 80;
|
||
server_name weighted.example.com;
|

|

|
||

|

# 权重计算示例:
|
||
#
|
||
# 总权重 = 5 + 3 + 2 = 10
|
||
#
|
||
# 每 10 个请求的分配:
|
||
# backend1: 5 个请求 (50%)
|
||
# backend2: 3 个请求 (30%)
|
||
# backend3: 2 个请求 (20%)
|
||
#
|
||
# 实际分配序列: 1,1,1,1,1,2,2,2,3,3, 1,1,1,1,1,2,2,2,3,3...
|
||
#
|
||
# 使用场景:
|
||
# 1. 高性能服务器分配更多请求
|
||
# 2. 新服务器逐步上线（先设置低权重）
|
||
# 3. 混合部署（物理机权重高，虚拟机权重低） |
