我正在尝试在VPS服务器中托管Rails应用程序。服务器已经安装了Apache，所以我首先尝试安装乘客，然后是乘客-apache-module。
我已经安装了RVM作为用户，并安装了ruby 1.9.3并将其设置为默认的ruby。然后，我安装了乘客gem，版本3.0.17，因为我们正在迁移rails应用程序，旧服务器中的乘客版本是3.0.17。我能够使用命令gem install passenger -v 3.0.17安装乘客宝石。
安装乘客后，我继续尝试使用passenger-apache-module命令安装passenger-install-apache2-module。我得到了这个输出：
Checking for required software...

* Curl development headers with SSL support... not found

Some required software is not installed.
But don't worry, this installer will tell you how to install them.
Press Enter to continue, or Ctrl-C to abort.
当我按Enter键时，我收到了这个输出：
Installation instructions for required software
* To install GNU C++ compiler:
Please run yum install gcc-c++ as root.
* To install Curl development headers with SSL support:
Please run yum install curl-devel as root.
* To install OpenSSL development headers:
Please run yum install openssl-devel as root.
* To install Zlib development headers:
Please run yum install zlib-devel as root.
If the aforementioned instructions didn't solve your problem, then please take
a look at the Users Guide:
/home/federaltitle/.rvm/gems/ruby-1.9.3-p448/gems/passenger-3.0.17/doc/Users guide Apache.html
但是，当我尝试以root用户身份安装消息（yum install gcc-c++，yum install curl-devel，yum install openssl-devel，yum install zlib-devel）中提到的库时，它会说所有库已经安装并且是最新的。
OS - CENTOS 6.4 x86_64
答案 0 :(得分：0)
我能够以root用户身份安装rvm，ruby和passenger，并解决了问题。当用户完成时，与权限有关。但是我必须为ruby部分上的用户相关活动做一些变通办法，例如bundle install，rake assets:precompile（必须以root用户身份执行此操作，因此为本地用户提供sudo权限以执行这些操作）。 / p>
