我有安裝捆綁的，我知道這是因爲我沒有「捆綁」。

這裏是我的Apache CONFIGS： /etc/apache2/sites-enabled/000-default.conf：

<VirtualHost *:80> 
    PassengerRoot /usr/local/rvm/gems/ruby-1.9.2-p0/gems/passenger-2.2.15 
    PassengerRuby /usr/local/rvm/rubies/ruby-1.9.2-p0/bin/ruby 
    ServerName 173.230.152.41 
    DocumentRoot /srv/rails_app/current/public 
    <Directory "/srv/rails_app/current/public"> 
     AllowOverride all 
     Options -MultiViews 
    </Directory> 
</VirtualHost> 

/etc/apache2/apache2.conf中：

# 
# Based upon the NCSA server configuration files originally by Rob McCool. 
# 
# This is the main Apache server configuration file. It contains the 
# configuration directives that give the server its instructions. 
# See http://httpd.apache.org/docs/2.2/ for detailed information about 
# the directives. 
# 
# Do NOT simply read the instructions in here without understanding 
# what they do. They're here only as hints or reminders. If you are unsure 
# consult the online docs. You have been warned. 
# 
# The configuration directives are grouped into three basic sections: 
# 1. Directives that control the operation of the Apache server process as a 
#  whole (the 'global environment'). 
# 2. Directives that define the parameters of the 'main' or 'default' server, 
#  which responds to requests that aren't handled by a virtual host. 
#  These directives also provide default values for the settings 
#  of all virtual hosts. 
# 3. Settings for virtual hosts, which allow Web requests to be sent to 
#  different IP addresses or hostnames and have them handled by the 
#  same Apache server process. 
# 
# Configuration and logfile names: If the filenames you specify for many 
# of the server's control files begin with "/" (or "drive:/" for Win32), the 
# server will use that explicit path. If the filenames do *not* begin 
# with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log" 
# with ServerRoot set to "" will be interpreted by the 
# server as "//var/log/apache2/foo.log". 
# 

### Section 1: Global Environment 
# 
# The directives in this section affect the overall operation of Apache, 
# such as the number of concurrent requests it can handle or where it 
# can find its configuration files. 
# 

# 
# ServerRoot: The top of the directory tree under which the server's 
# configuration, error, and log files are kept. 
# 
# NOTE! If you intend to place this on an NFS (or otherwise network) 
# mounted filesystem then please read the LockFile documentation (available 
# at <URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile>); 
# you will save yourself a lot of trouble. 
# 
# Do NOT add a slash at the end of the directory path. 
# 
ServerRoot "/etc/apache2" 

# 
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK. 
# 
#<IfModule !mpm_winnt.c> 
#<IfModule !mpm_netware.c> 
LockFile /var/lock/apache2/accept.lock 
#</IfModule> 
#</IfModule> 

# 
# PidFile: The file in which the server should record its process 
# identification number when it starts. 
# This needs to be set in /etc/apache2/envvars 
# 
PidFile ${APACHE_PID_FILE} 

# 
# Timeout: The number of seconds before receives and sends time out. 
# 
Timeout 300 

# 
# KeepAlive: Whether or not to allow persistent connections (more than 
# one request per connection). Set to "Off" to deactivate. 
# 
KeepAlive On 

# 
# MaxKeepAliveRequests: The maximum number of requests to allow 
# during a persistent connection. Set to 0 to allow an unlimited amount. 
# We recommend you leave this number high, for maximum performance. 
# 
MaxKeepAliveRequests 100 

# 
# KeepAliveTimeout: Number of seconds to wait for the next request from the 
# same client on the same connection. 
# 
KeepAliveTimeout 15

# DefaultType is the default MIME type the server will use for a document

LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.2-p0/gems/passenger-2.2.15/ext/apache2/mod_passenger.so 

那麼我該如何去做這個工作？

Answer 1

您需要關注RVM's instructions以生成乘客包裝腳本，以便在您的PassengerRuby線上使用。沒有它，你將沒有設置適當的環境變量，Apache將無法找到在該RVM安裝中安裝的gem。

Answer 2

跟着@克里斯的回答。如果您在Ubuntu和使用Apache做到以下幾點：

rvm install 1.9.2 
rvm 1.9.2 --passenger 
gem install passenger 
rvmsudo passenger-install-apache2-module 

然後在你的apache.conf添加/修改下面幾行：

LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.2-p0/gems/passenger-2.2.15/ext/apache2/mod_passenger.so 
PassengerRoot /usr/local/rvm/gems/ruby-1.9.2-p0/gems/passenger-2.2.15 
PassengerRuby /usr/local/bin/passenger_ruby 

這個工作對我來說，SO拖網小時後其餘的互聯網。

Answer 3

應該指出的是，Passenger 3原生支持RVM，沒有特別的指示。 RVM網站上的乘客指令將會過時。
