有一个带有栏杆的产品，ubuntu 14，nginx，乘客。 原因安全度量建议我，我在生产服务器中进行了Nginx升级。遵循他们在这篇文章中所说的步骤： update-nginx-in-ubuntu-14-04 (first answer) 现在网络向我抛出了403 Forbidden。 在服务器上运行
nginx -v && sudo service nginx status
nginx version: nginx/1.14.0
* nginx is running
这：
passenger -v
Phusion Passenger 5.0.30
看来他已经升级并开始运行了。
当我运行此sudo tail -20 /var/log/nginx/error.log （更改了IP和应用名称） 我得到了这个输出
