[Linux]Fedora17/18安装Ruby1.8 和 Redmine 2.2

最近从CentOS转到Fedora，很多功能都不用自己编译安装了，yum install *** 就解决了，

比如安装Linux下的ASP.NET的WEB运行环境就这样：

yum install vim mono-* mariadb mariadb-* httpd haproxy redis

mariadb是Mysql的开源分支，用起来也爽，haproxy是4层网络和7层网络的负载均衡工具，可做反向代理用，redis就不用说了，nodb内存数据库

mono是asp.net的Linux运行环境，相当于.Net Framework

但是，装redmine时碰到一点问题，采用yum安装的是RUBY 1.9，

但我用的Redmine导入问题插件用到的Ruby1.8的特色功能“fastercsv”，没办法，只能找方法装上Ruby1.8.7，

方法如下:

#安装rvm:
curl -#L https://get.rvm.io | bash -s stable
ldconfig
source /etc/profile
rvm autolibs enable
#安装运行需要的库:
yum install git patch gcc-c++ readline-devel zlib-devel libyaml-devel libffi-devel openssl-devel autoconf automake libtool bison libxml2-devel libxslt-devel ImageMagick-devel
#安装Ruby1.8.7
rvm install 1.8.7
#在redmine2.2.0目录中运行,安装redmine需要的组件：
gem install bundler

以下是我Redmine目录下的Gemfile文件的内容:

Dir.glob File.expand_path("../plugins/*/Gemfile", __FILE__) do |file|

OVER，可以运行Redmine了！
