使用mongrel来跑ruby程序 ，Ruby提供一个安装Ruby程序为服务的包：mongrel_service。安装其实很简单，运行：gem install mongrel_service

[root@test-1 config]#gem install mongrel_service

[root@test-1 config]# ruby /usr/local/redmine/script/server mongrel -e production -d

如果需要指定端口只需要加 -p 端口号

问题之前：本来可以使用mongrel来跑ruby程序，由于效率问题，以及一个同事没有权限访问80之外端口的原因决定部署在apache上。

安装Passenger

[root@test-1 config]#gem install passenger
passenger-install-apache2-module

#If the second line does not work, do whereis passenger to find out where it is installed.
So you can execute it like /usr/local/bin/passenger-install-apache2-module ...

The install process is interactive and you wil be told what to do. READ!

问题1：我的redhat服务器yum没有注册，卸载后安装了centos的yum。

下载如下包，安装yum

[root@test-1 public]# wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-3.2.22-40.el5.centos.noarch.rpm
[root@test-1 public]# wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
[root@test-1 public]# wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-4.el5.x86_64.rpm<pre code_snippet_id="235942" snippet_file_name="blog_20140317_3_9588108" name="code" class="html">[root@test-1 public]#wget http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5

问题2：我的apache passenger模块安装好后提示有些软件没有安装，使用yum安装，运行如下命令时，如果缺少一些安装包，会提示，安装即可。

[root@test-1 public]# wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/apr-util-devel-1.2.7-11.el5_5.2.x86_64.rpm

[root@test-1 public]# wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/httpd-2.2.3-82.el5.centos.x86_64.rpm

问题3：安装完成之后提示配置apache，修改它，添加如下内容，如果还有问题只能网上搜解决了，这个用了不少时间，主要理解下面配置的含义。。

解决问题中常用命令，建立一个软链放在apache DocumentRoot ，针对配置文件的

<p>[root@test-1 public]# ln -s /usr/local/redmine/public/ /var/www/html/redmine </p><p></p><pre code_snippet_id="235942" snippet_file_name="blog_20140314_3_4137501" name="code" class="html">      <directory></directory>
