nginx配置后台代理

前端访问后台API前置标识为/api，在nginx增加api代理访问配置，配置如下：

location /api/ {
    proxy_pass http://192.168.160.21:9001/;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    # 启 用 支 持 websocket连 接
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}
