搭建redmine

Ruby 2.0.0 redmine4.0.9 Rails4.2

tar -zxvf ruby-2.5.0.tar.gz

cd ruby-2.5.0

###创建安装目录：

mkdir -p /usr/local/ruby

###配置并制定安装位置：

./configure --prefix=/usr/local/ruby

###编译与安装

###建立软链接  

ln -s /usr/local/ruby/bin/ruby /usr/local/bin/ruby

echo "export PATH=$PATH:/usr/local/ruby/bin/" >> /etc/profile
