nginx 负载均衡配置

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

upstream backend {server 192.168.1.182:7443;  # ✅ 只写 IP:Portserver 192.168.1.182:7444; 
}server {location /api/ {#rewrite ^/api(.*)$ $1 break;  过滤掉apiproxy_pass http://backend/api/;  # 路径在这里指定}
}

---常用配置

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 $http_upgrade;proxy_set_header Connection 'upgrade';proxy_cache off;proxy_buffering off;      # 禁用缓冲proxy_buffer_size 4k;     # 减小缓冲区大小，加快首包返回proxy_read_timeout 300s;  # 可适当调大超时时间（根据业务）proxy_send_timeout 300s;proxy_pass http://127.0.0.1:8001;}    location /ollama {rewrite ^/ollama(.*)$ $1 break;proxy_pass http://127.0.0.1:5612; #python 接口proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;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chunked_transfer_encoding on;  #开启分块传输编码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}
