Capistrano部署配置 [英] Capistrano deploy configuration

问题描述

请帮助配置capistrano进行部署。
我有ssh：

• 用户：用户


• 主机：8.8.8.8： 6554


• 传递：123

然后我有bitbucket存储库[e-mail]：somerepo /code.git

• 用户：[e-mail]


• 传递：repopass

我只需要将代码从默认分支部署到User@8.8.8.8：8888：/ public_html / test /。在本地机器上我有ssh密钥，允许我无需密码连接。

 > lock'3.3.5'
 set：application，'App'
 set：scm，：git 
 set：repo_url，'[e-mail]：somerepo / code.git'
 set：scm_passphrase，
 set：scm_user，[e-mail]
 set：user，'User'
 set：deploy_to，'/ public_html / test'
 set：app_dir，/ public_html / test
 set：ssh_options，{：forward_agent => true：
角色：web，'8.8.8.8:6554'
 
命名空间：deploy do 
 after：restart，：clear_cache do 
角色（：web） ，在：：groups，limit：3，wait：10 do 
 end 
 end 
 end 
  

错误：

由远程主机关闭连接
**调用deploy：failed（first_time）
**执行部署：失败

解决方案

/ strong> in Gemfile

  gem'capistrano'
 gem'capistrano-bundler'
 gem'capistrano -rails'
  

第2步：套餐

第3步： cap install ##它会生成一组文件
$步骤4：进入 Capfile 并粘贴以下代码##该文件将与您的Rails应用程序并行 p>

 要求'capistrano / setup'
r Equire'capistrano / deploy'
 require'capistrano / bundler'
 require'capistrano / rails / assets'
 require'capistrano / rails / migrations'
 Dir.glob（'lib /capistrano/tasks/*.rake').each {| r | import r} 
  

第5步： Config / deploy.rb通用于 ENV

此文件将在应用程序环境中共享/共享

  set：application，'your_app'##请记住，您的应用程序目录名称为your_app 
 set：repo_url，'git @ bitbucket .org：somerepo / code.git'
 set：branch，'master'
 set：use_sudo，true 
 set：deploy_to，'/ public_html / test'
 set：linked_files （'linked'，']）。push（'config / database.yml'）
 set：linked_dirs，fetch（：linked_dirs，[]）push（'bin'，'log'，'tmp / pids'，'tmp / cache'，'tmp / sockets'，'vendor / bundle'，'public / system'）
 namespace：deploy do 
 
 after：restart，：clear_cache do 
在角色（：web）上，在：：groups，limit：3，wait：10 do 
＃在这里我们可以做任何事情，例如：
＃在releas e_path do 
＃execute：rake，'cache：clear'
＃end 
 end 
 end 
 
 end 
  现在可以创建ENV专用文件用于生产环境 
  
 $ b 
  config / deploy / production.rb  ##此文件将由 cap install  
 
可以评论除此之外的所有代码
角色：app，％w {8.8.8.8:6554} 
设置：ssh_options，{
用户：'用户'
} 
  
 第6步：现在执行 ssh到您的服务器  ssh User@8.8.8.8：6554  
现在它会要求密码... 给密码现在，默认情况下，您的应用将转到 / var / www / app  code>，在这里您需要相应地创建文件夹。但在您的情况下，您 s et：deploy_to，'/ public_html / test'＃确保Dir名字后面跟着/'正斜杠'这个错误，我做过很多次了 
 
 
 sudo chown用户：User / public_html / test＃`chown`会改变船主所以'用户'用户可以'**读/写'
 umask 0002 
 mkdir / public_html / test / releases ##这些是约定
 mkdir / public_html / test / shared＃ ＃这些是约定
 sudo chown User：User public_html / test / releases 
 sudo chown User：User public_html / test / shared 
 mkdir .ssh 
 chmod .ssh 007 
 ssh-keygen -t rsa 
并按照步骤##这将生成ssh密钥
 cat .ssh / id_rsa.pub 
  
现在将此密钥添加到您的存储库中go => setting =>部署密钥Button =>点击该密钥并添加密钥 即可。将标签名称放入您想要的任何内容，然后在此处粘贴 ssh键。
 
 
 
 从服务器一方  
 
 
 第8步：现在您需要添加ssh如果你有 rsa 键，那么 cat〜/ .ssh / id_rsa.pub 第三步：使用ssh登录到你的服务器
 
 $ b  
 `vi .ssh / authorized_keys`并粘贴本地机器rsa密钥
  
保存并退出
 
 
 
 第10步：>  cap -T  ##列出所有任务
 
 
 
 第11步：  cap production deploy：check  
 
它会抛出错误，因为database.yml文件不存在
 
 
 
对于 vi /public_html/test/shared/config/database.yml  
 开发：
适配器：postgresql 
数据库：testdb_cap 
池：5 
超时：5000 
  
 保存并退出 
 
 
 
再次 cap production deploy：check  $ b 这一次不会引发任何错误 
 
 
 第12步： 
 产量部署
  
这就是它 
 
 
检查这也部署后的ruby rake任务 
 
Help please to configure capistrano for deployment.
I have ssh:


user: User 
host: 8.8.8.8:6554
pass: 123


Then i have bitbucket repository [e-mail]:somerepo/code.git


user: [e-mail]
pass: repopass


I am just need to deploy code from default branch to User@8.8.8.8:8888:/public_html/test/ . On local machine i have ssh key, that allows me to connect without password. But capistrano didn't connect.

There is my config:
lock '3.3.5'
set :application, 'App'
set :scm, :git
set :repo_url, '[e-mail]:somerepo/code.git'
set :scm_passphrase, ""
set :scm_user, "[e-mail]"
set :user, 'User'
set :deploy_to, '/public_html/test'
set :app_dir, "/public_html/test"
set :ssh_options, {:forward_agent => true}
role :web, '8.8.8.8:6554'

namespace :deploy do
  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
    end
  end
end
Error:

  
connection closed by remote host
  ** Invoke deploy:failed (first_time)
  ** Execute deploy:failed

解决方案
Step 1: in Gemfile
gem 'capistrano'
gem 'capistrano-bundler'
gem 'capistrano-rails'
Step 2: bundle

Step 3: cap install ## it will generate set of file 

Step 4: go in Capfile and paste the following code ## this file will be parallel to your rails application
require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }
Step 5: Config/deploy.rb that will be common to both ENV

This file will be shared/common across the application environment
    set :application, 'your_app'  ## keep in mind that your app dir name will be your_app  
    set :repo_url, '[e-mail]:somerepo/code.git'
    set :branch, 'master'
    set :use_sudo, true
    set :deploy_to, '/public_html/test'
    set :linked_files, fetch(:linked_files, []).push('config/database.yml')
    set :linked_dirs, fetch(:linked_dirs, []).push('bin', 'log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system')
namespace :deploy do

  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake, 'cache:clear'
      # end
    end
  end

end
Step6: Lets create ENV specific file for now For production Environment

config/deploy/production.rb  ## this file will be generate by cap install command that you did earlier no need for this time

do comment all the code except this
role :app, %w{8.8.8.8:6554}
set :ssh_options, {
                user: 'User'
            }
Step 6: now do ssh to your server ssh User@8.8.8.8:6554
now it will ask for the password ... give password

Step 7: now by default  your app will go /var/www/app and here you need to create the folder accordingly But in your case as you set :deploy_to, '/public_html/test'   # make sure Dir name is followed by / 'Forward slash' this mistake i did many times 
sudo mkdir -p /public_html
sudo mkdir -p /public_html/test
sudo chown User:User /public_html/test # `chown` will change the owner ship so that `User` user can `**Read/Write**` 
umask 0002
mkdir /public_html/test/releases ## these are convention 
mkdir /public_html/test/shared ## these are convention 
sudo chown User:User public_html/test/releases
sudo chown User:User public_html/test/shared
mkdir .ssh
chmod .ssh 007
ssh-keygen -t rsa
and follow the step  ## this will generate ssh key 
cat .ssh/id_rsa.pub
Now add this key to your repo's go to => setting => deployment keys Button => click on that and add Key. Put the label name any thing you want and paste the ssh key here.

That it from server side 

Step8: Now you need to add your ssh key to server 
For that do cat ~/.ssh/id_rsa.pub if you have rsa key other wise generate rsa key it is very easy to crate

Step 9: Login to your server using ssh 
`vi .ssh/authorized_keys` and paste your local machine rsa key 
save and exit 

Step 10 : cap -T  ## list out all the task 

step 11: cap production deploy:check

It will throw an error because database.yml file is not there

For that vi /public_html/test/shared/config/database.yml
    development:
  adapter: postgresql
  database: testdb_cap
  pool: 5
  timeout: 5000
save and exit

Do again cap production deploy:check

This time would not throw any error 

Step 12:
 cap production deploy
And That's it 

Check this also ruby rake task after deploymewnt
