    橙色是主要配置信息;

    如果有一个服务器挂了,比如:localhost:9001 服务区器挂了,Nginx还能继续访问9001吗?不能Nginx只会访问正常工作的服务器。如果9001 恢复正常工作时,Nginx会继续正常访问吗?会的,正常访问不受影响。

        upstream NET5WebApi  #NET5WebApi 自定义个名称
        {
            server localhost:9001 weight=20;  #9001处理 20次
            server localhost:9002 weight=30;  #9002处置 30次
            server localhost:9003 weight=50;  #9003处置 50次
            #weight权重,根据服务器性能,适当的分配请求数量,数字越大分配的请求数量越多。
