部署 – 使用capistrano Nginx Passenger MYSQL将rails部署到VPS
作者：互联网
这是我第一次部署rails应用程序,我发现这个过程非常令人沮丧.出于工作原因,我们使用Rackspace云与Ubuntu 12.04 LTS(精确穿山甲)和MYSQL而不是Heroku路线.
我一直试图解决这个问题2天,我终于转向社区寻求帮助了.目前我的服务器上出现“404 Not Found Error”
我跟随Ryan的Screencasts“部署到VPS”,“Capistrano食谱”,this tutorial和其他谷歌等等,我仍然不在那里.
我设法安装了以下内容：
> Node.js
> RVM
> ruby 1.9.3p194(2012-04-20修订版35410)[x86_64-linux]
> Rails 3.2.8
> MYSQL
>乘客
> Nginx
我很确定我在Capistrano Deployer中遗漏了一些简单的东西：
require "bundler/capistrano"
server "198.101.242.242", :web, :app, :db, primary: true
set :application, "myapp"
set :user, "deployer"
set :deploy_to, "/home/#{user}/#{application}"
set :deploy_via, :remote_cache
set :use_sudo, false
set :scm, "git"
set :repository, "git@github.com:xxxx/#{application}.git"
set :branch, "master"
default_run_options[:pty] = true
ssh_options[:forward_agent] = true
# if you want to clean up old releases on each deploy uncomment this:
after "deploy", "deploy:cleanup"
# if you're still using the script/reaper helper you will need
# these http://github.com/rails/irs_process_scripts
# If you are using Passenger mod_rails uncomment this:
namespace :deploy do
task :start do ; end
task :stop do ; end
task :restart, :roles => :app, :except => { :no_release => true } do
run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
end
end
在部署之前我应该做些什么吗？
这是Nginx错误日志：

谢谢.
解决方法:
好的,所以我最终通过试验和错误以及Beef Jerky’s评论找出了问题.
第一个问题是capistrano无法从我的具有依赖项的应用程序安装一些gem.所以我在生产中安装了那些…特别是rvm capistrano gem和rmagick. RVM Capistrano宝石是主要问题,也是我在拆开时遇到错误的原因. rmagick是在修复rvm问题之后出现的,我通过安装它的dependents解决了这个问题.
我遇到的第二个问题是指向我的应用程序文件夹myapp / public而不是Nginx服务器配置文件中的当前版本myapp / current / public.所以我保留了现有的服务器块并将我的设置放在里面,然后就可以了.以下是Nginx服务器配置文件的设置
server {
listen 80;
server_name localhost;
root /home/deployer/banking_analytics/current/public; # <--- be sure to point to 'public'!
passenger_enabled on;
# listen 80;
# server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
# location / {
# root html;
# index index.html index.htm;
# }
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
# error_page 500 502 503 504 /50x.html;
# location = /50x.html {
# root html;
# }
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php${
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#

# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
