我在同一台机器上安装了一个闪亮的服务器和一个nginx服务器。 我设法访问nginx和闪亮的主页。我希望当我输入具有身份验证的nginx服务器的地址时，将我重定向到闪亮的页面，我尝试了很多指令，但没有一个工作，他们将我发送回页面d nginx错误

除了跳过身份验证的指令重写之外。

您启用了SELinux或AppArmor，并将其配置为拒绝nginx打开到后端的传出连接（这可能是您的unix发布的默认设置）。
检查日志以了解原因：
cat /var/log/audit/audit.log | grep nginx | grep denied
解决方案是允许nginx网络访问（仅适用于具有SELinux的发行版）：
setsebool -P httpd_can_network_connect 1
