从基础配置到负载均衡器部署的完整指南
如何实现VPS远程均衡配置？

# 检查服务器网络连通性
ping 192.168.1.101
ping 192.168.1.102
更新系统软件包
apt update && apt upgrade -y
安装必要工具
apt install -y net-tools curl wget

# nginx.conf 负载均衡配置
http {
    upstream backendservers {
        server 192.168.1.101:80 weight=3;
        server 192.168.1.102:80 weight=2;
        server 192.168.1.103:80 backup;
    }
    
    server {
        listen 80;
        location / {
            proxypass http://backendservers;
            proxysetheader Host $host;
            proxysetheader X-Real-IP $remoteaddr;
        }
    }
}

# 在后端服务器上部署应用
假设使用Node.js应用
cd /var/www
git clone 
npm install
pm2 start app.js

# 健康检查配置
upstream backendservers {
    server 192.168.1.101:80 maxfails=3 failtimeout=30s;
    server 192.168.1.102:80 maxfails=3 failtimeout=30s;
    
    # 主动健康检查
    check interval=3000 rise=2 fall=5 timeout=1000;
}

步骤五：会话保持配置

# 基于IP的会话保持
upstream backendservers {
    iphash;
    server 192.168.1.101:80;
    server 192.168.1.102:80;
}
或者使用cookie方式
sticky cookie srvid expires=1h domain=.example.com path=/;
