我一直在尝试使用nginx为两个tomcat服务器配置负载均衡器。首先,我在不同网络端口(8080和8081)上的两个不同的tomcat服务器上启动了项目,并且该项目可以正常工作。 然后,我在Windows 10上下载了nginx,启动了它,并在本地主机上获得了“欢迎使用nginx页面”:80。
然后我在nginx conf文件上添加了一些修改,以配置负载均衡器
upstream new_servers {
least_conn;
server 127.0.0.1:8081;
server 127.0.0.1:8080;
}
和位置
location / {
root html;
index index.html index.htm;
proxy_pass http://new_servers;
}
我尝试执行“ nginx -s reload”,我停止了nginx并重新启动它,但似乎没有任何效果,我总是得到
400 http错误
这是所有conf文件

我的问题是: 是什么造成了此错误?
一旦nginx可以工作?会将我重定向到其中一台服务器吗?
我已经在这个问题上工作了两天,所以我非常感谢您的帮助。
提前谢谢

更改nginx默认端口即可解决此问题。
要回答问题,是的,nginx确实将我重定向到其中一台服务器。
如果您想查看我们重定向到的服务器,只需添加
log_format main 'to: $upstream_addr : $remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
然后转到acces文件,查看我们重定向到的服务器“ 到“
