我查阅了这份文档（如何在 Ubuntu 上使用Passenger 安装Rails 和nginx）。目前我正在使用Ubuntu 14.04.4 LTS. 这次我第一次用rails安装ruby ..我该如何解决这个问题？？

rvm install 2.3.1

我的 Webserver(Nginx) 文件夹中有五个文件：

  1. cert_www.Mydomain.com.crt
  2. prv_www.Mydomain.com.key
  3. rootca_www.Mydomain.com.crt
  4. subca1_www.Mydomain.com.crt
  5. subca2_www.Mydomain.com.crt

我想合并crt文件。但我的命令不起作用。我正在使用 cat 命令。请参阅以下命令。

ubuntu@ip:/etc/nginx/ssl$ sudo cat cert_www.Mydomain.com.crt subca1_www.Mydomain.com.crt rootca_www.Mydomain.com.crt > www.Mydomain.com.pem
-bash: www.Mydomain.com.pem: Permission denied

我不明白，不太确定出了什么问题。
