nginx 负载均衡配置

舰长1152025-10-14 8:43

报错nginx: $emerg$ invalid host in upstream "10.67.208.182:7443/yqbapi/" in /usr/local/nginx/conf/nginx.conf:37

upstream 后面不能直接更名字，可以在loccation里面配置

复制代码

upstream backend {
    server 192.168.1.182:7443;  # ✅ 只写 IP:Port
    server 192.168.1.182:7444; 
}

server {
    location /api/ {
        #rewrite ^/api(.*)$ $1 break;  过滤掉api
        proxy_pass http://backend/api/;  # 路径在这里指定
    }
}

---常用配置

复制代码

		location /ai_api {	
		 rewrite ^/ai_api(.*)$ $1 break;
				proxy_set_header Host $host:$server_port;
				proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
				proxy_set_header X-Real-IP $remote_addr;
				proxy_http_version 1.1;
			    proxy_set_header Upgrade $http_upgrade;
			    proxy_set_header Connection 'upgrade';
			    proxy_cache off;
			    proxy_buffering off;      # 禁用缓冲
			    proxy_buffer_size 4k;     # 减小缓冲区大小，加快首包返回
			    proxy_read_timeout 300s;  # 可适当调大超时时间（根据业务）
			    proxy_send_timeout 300s;
				proxy_pass http://127.0.0.1:8001;

                    rewrite ^/ollama(.*)$ $1 break;
            proxy_pass http://127.0.0.1:5612; #python 接口
            proxy_set_header Host $host;

            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
                        proxy_cache off;  #关闭缓存
                        proxy_buffering off;  #关闭代理缓冲

                        tcp_nopush on;  #开启TCP NOPUSH选项，禁止Nagle算法
                        tcp_nodelay on;  #开启TCP NODELAY选项，禁止延迟ACK算法
                        keepalive_timeout 300;  #设定keep-alive超时时间为300秒
        }
