 不知道是不是我在  conf文件夹下面 随手复制nginx.conf,然后在这个复制的文件基础上重命名的原因...

Answer 1

用 telnet 命令测试一下 upstream 能否连上

telnet 192.108.1.102 8999
telnet 192.108.1.102 8888

Answer 2

他错误不是说你的host有问题么，nginx机器上 curl http://192.108.1.102:8999/index.html 看看

Answer 3

192.168.1.102:8999 192.168.1.102:8888 直接访问这两个看通不通

Answer 4

... 各位大佬,不好意思,我的原因

前面确实telnet 一直不通( IP 一半写对了,一般写错了,这是一个原因 ), 后面   又重新 搭了一个web站点 + 电脑重启

该通的都通了.

192.168.1.102:8999 192.168.1.102:8888 只有这两个没通了

 我后面仔细想了想,为什么这两个端口没有通 ,而8086端口能通了
 误解了Nginx 的意思,后面想了想   

server  {  

listen 8086 这里是你要监听的端口

...

} 

server 192.108.1.102:8999 weight=1;  这里是要指向你网站的端口 

8999  我根本就没有配置.....!!!!

现在我配置了一下,好了, Telnet 也通了

谢谢各位大佬,谢谢 @dudu

自己粗心了
