安装ruby环境
RVM（ruby版本管理工具）安装
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
curl -sSL https://get.rvm.io | bash -s stable
source /etc/profile.d/rvm.sh
列出所有可用的ruby版本
rvm list known
安装一个ruby版本
rvm install 2.2
或者，安装最新版本
rvm install ruby
设置新版本ruby为默认版本
rvm use 2.2 --default
检查当前ruby版本
ruby -v
安装Nginx
创建nginx源文件
# vi /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
安装nginx
yum -y install nginx
启动nginx并设为自启动服务
chkconfig nginx on
service nginx start
安装Rails和Puma
由于国内网络原因，导致 rubygems.org 存放在 Amazon S3 上面的资源文件间歇性连接失败。
解决办法：
修改Ruby的gem源地址为淘宝的源
gem sources --add https://ruby.taobao.org/ --remove https://rubygems.org/
检查Ruby的gem源
gem sources -l
安装rails
gem install rails
查看rails版本
rails -v
安装puma
gem install puma
查看puma版本
puma --version
启动puma
首先，确保你把Puma加入了你的ruby应用的Gemfile文件中。
gem 'puma'
后用Rails命令启动Puma
rails s Puma
配置Nginx
删除默认站点配置文件
rm /etc/nginx/conf.d/default.conf
为你的ruby应用创建一个站点配置文件
# vi /etc/nginx/conf.d/my_app.conf
upstream my_app {
server unix:///var/run/my_app.sock;
}
server {
listen 80;
server_name my_app_url.com; # change to match your URL
root /var/www/my_app/public; # I assume your app is located at this location
location / {
proxy_pass http://my_app; # match the name of upstream directive which is defined above
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location ~* ^/assets/ {
# Per RFC2616 - 1 year maximum expiry
expires 1y;
add_header Cache-Control public;
# Some browsers still send conditional-GET requests if there's a
# Last-Modified header or an ETag header even if they haven't
# reached the expiry date sent in the Expires header.
add_header Last-Modified "";
add_header ETag "";
break;
}
}
重启nginx
service nginx restart
