Nginx配置多台机器实现负载均衡的教程详解

# load_balancer.conf

# 定义upstream，指定服务器列表
upstream backend {
    server 192.168.1.100;
    server 192.168.1.101;
}

# 配置负载均衡策略
# 在这个例子中，我们使用默认的轮询策略
# 其他常见的负载均衡策略还包括ip_hash、least_conn等
# 你可以根据需求选择合适的策略
# 更多详情请查看nginx文档：http://nginx.org/en/docs/http/ngx_http_upstream_module.html
server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://backend;
        # 如果你需要传递客户端的IP地址到后端服务器，可以使用下面的配置
        # proxy_set_header X-Real-IP $remote_addr;
        # proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        # proxy_set_header Host $http_host;
        # proxy_set_header X-NginX-Proxy true;
        # proxy_redirect off;
    }
}
