新手问题 [已解决] Capistrano 用户验证问题？

问题

在我的理解里，我在自己的 app 代码中部署好了 capistrano , 输入

cap production deploy:setup

然后它提示我输入密码，应该就搞定了……

可事实是，它没让我输入密码，直接就提示我

DEBUG[dd17face] Running /usr/bin/env [ -d ~/.rvm ] on xxx.xxxx.xxxx.xx
DEBUG[dd17face] Command: [ -d ~/.rvm ]
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing on hostxxx.xxxx.xxxx.xx
: Authentication failed for user [email protected]


Net::SSH::AuthenticationFailed: Authentication failed for user [email protected]

Tasks: TOP => rvm:hook

怎么破？

后来，我就在 config/environments/production.rb 中加了一句

set :password, ask('Server password:', nil)
server 'server.domain.com', user: 'ssh_user_name', port: 22, password: fetch(:password), roles: %w{web app db}

它倒是问我密码了，可是竟然明文显示密码，这就算了，结果还是搞不定，显示的结果是：

$ cap production deploy:setup        

Please enter Server password (): xxxx
DEBUG[5db14c73] Running /usr/bin/env [ -d ~/.rvm ] on xxx.xxxx.xxxx.xx

DEBUG[ab50c1ba] Running /usr/bin/env [ -d ~/.rvm ] on xxx.xxxx.xxxx.xx

DEBUG[ab50c1ba] Command: [ -d ~/.rvm ]
DEBUG[5db14c73] Command: [ -d ~/.rvm ]
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing on host xxx.xxxx.xxxx.xx
: connection closed by remote host

Net::SSH::Disconnect: connection closed by remote host

EOFError: end of file reached

Tasks: TOP => rvm:hook
(See full trace by running task with --trace)

难道会是我的 rvm 地址没设置对吗？

好吧，目前我正在研究这个文档

解决方案

增加从本机到服务器的 SSH

# Mac OSX 上 ssh-copy-id不是默认安装的，可通过Homebrew进行安装
    brew install ssh-copy-id

#  将私钥加入ssh-agent管理：
     ssh-add ira                                       # (注：ira指的是私钥名称)

# 公钥加到远程服务器
      ssh-copy-id -i ~/.ssh/yby.pub [email protected]

建议先学习配置 ssh 连接自己服务器，github，bitbucket. 再回头就简单多了。

在服务器中加入本机的 key

来自 RubyChina4Android

chairy11 #4 2014年11月20日

#2 楼 @flowerwrong 我平时 push 代码到 github，bitbucket 都是用 SSH 的。服务器之前 pull 代码也是用 SSH 通过验证的。不过我没试过从自己机子到服务器用 SSH，我折腾下……

chairy11 #5 2014年11月20日

#3 楼 @bestjane #2 楼 @flowerwrong 已经在服务器加上我本机的 SSH KEY，因为我现在输入 ssh [email protected]，不用密码就能直接进入服务器了。 可是，运行

cap production deploy:check

会出现

没看懂这是哪里出错了……

flowerwrong #6 2014年11月20日

昨天听你说你的 gemfile.lock 里面 cap 是 2，你把他删掉，重新重新 bundle install 试下

rm Gemfile.lock
bundle install

chairy11 #7 2014年11月20日

#6 楼 @flowerwrong 我本机的已经是 cap 3 了。服务器的我这两天 commit 的没有更新，那看来我在第一次用 cap 之前，还是得先手动更新下次？ 我现在进服务器手动 git pull 最新代码了。

flowerwrong #8 2014年11月20日

手动git pull最新代码 不用，cap production deploy:check 会创建基础环境，过后cap production deploy 要不先玩这个 demo 吧 [email protected]:FlowerWrong/capdemo.git

# https://github.com/FlowerWrong/capdemo/blob/master/config/deploy.rb
set :deploy_to, '/home/ubuntu/www/capdemo'

# https://github.com/FlowerWrong/capdemo/blob/master/config/deploy/production.rb

role :web, %w{ubuntu@xxx}

# Extended Server Syntax
# ======================
# This can be used to drop a more detailed server definition into the

# used to set extended properties on the server.
server 'xxx', user: 'ubuntu', roles: %w{web app}, my_property: :my_value
chairy11 #9 2014年11月20日

#8 楼 @flowerwrong 不懂怎么玩啊。反正我现在按说服务器里刚已经 git pull , 并 bundle install，已经用了 cap 3 了。我还 touch tmp/restart.txt，如果平时手动更新也就这么个步骤了吧？

但还是同样出错。

是 capfile 吧？加了的

# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

但 deploy.rb 中，

# set :rvm_type, :system                     # Defaults to: :auto
set :rvm_ruby_version, '2.1.2p95'

在 deploy/production.rb 中

server 'xxx.xxx.xxx.xxx',
       user: 'root',
       roles: %w{web app},
       ssh_options: {
           user: 'root', # overrides user setting above
           keys: %w(/Users/yebiying/.ssh/yby),
           forward_agent: false,
           auth_methods: %w(publickey password)
          # password: 'please use keys'
        }

主要我还是没看出是哪里有错，

SSHKit::Runner::ExecuteError: Exception while executing on host xxx.xxx.xxx.xxx: ruby exit status: 2

好像都 google 不到 status:2 是指什么……

#10 楼 @flowerwrong 请教一下，deploy/production.rb 中

server 'xxx.xxx.xxx.xxx',
       user: 'root',
       roles: %w{web app},
       ssh_options: {
           user: 'root', # overrides user setting above
           keys: %w(/Users/yebiying/.ssh/yby),

           auth_methods: %w(publickey password)
          # password: 'please use keys'
        }

那个 keys , 是写的本机的私钥的地址，还是服务器中 publickey 的地址？

flowerwrong #13 2014年11月20日

#12 楼 @chairy11 部署到一台服务器一般不用写 server 那部分 server 'xxx', user: 'root', roles: %w{web app}, my_property: :my_value 就可以了

地址是你本机的私钥地址

# server 'example.com',
#   user: 'user_name',
#   roles: %w{web app},
#   ssh_options: {
#     user: 'user_name', # overrides user setting above
#     keys: %w(/home/user_name/.ssh/id_rsa),
#     forward_agent: false,
#     auth_methods: %w(publickey password)
#     # password: 'please use keys'
#   }

～/.ssh/config

Host bitbucket.org
  User flowerwrong
    Hostname bitbucket.org
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_bitbucket

Host github.com
  User flowerwrong
    Hostname github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_github

Host ip
  IdentityFile ~/.ssh/id_rsa_xx

#13 楼 @flowerwrong 终于前进了一点点。 现在发现之前的两三个小问题，一个是

set :rvm_custom_path, '/usr/local/rvm'  # only needed if not detected

而我本来的地址可能写的不对，写了"/usr/local/rvm/bin/rvm"

另一个是

set :rvm_ruby_version, '2.1.2'      # Defaults to: 'default'

我原来写的是 '2.1.2p95'

现在提示的新问题是：

ERRORlinked file /var/www/weekly.com/shared/config/database.yml does not exist on xxx.xxx.xxx.xxx
cap aborted!

但哪个放在 share 难道不应该是 capinstrano 自己搞的吗？我要自己复制过去？

#13 楼 @flowerwrong
另外，my_property: :my_value，这句是干什么的？ 我不知道从哪抄了句：

server 'xxx.xxx.xxx.xxx', user: 'root', roles: %w{web app db}, primary: true

但我也不知道 primary: true 是干什么的……

看看 cap 执行的什么命令，自己 ssh 上服务器一条条的敲，看看对不对

chairy11 #19 2014年11月20日

#13 楼 @flowerwrong #18 楼 @jimrokliu 现在执行的命令应该是

cap production deploy:check:linked_files

提示的是：

file /var/www/weekly.com/shared/config/database.yml does not exist

我手动复制过去好吗？还是说应该在哪里设置一下的？

chairy11 #20 2014年11月20日

#13 楼 @flowerwrong #18 楼 @jimrokliu 额，我手动把 database.yml 复制到 shared 下了…… 是复制不是移动，因为 rails 本身好像是会回到原来的 config 位置找的，另外设置貌似也有点复制，我就先让它同时存在了，这样好吗？

#21 楼 @chairy11 谢谢您的文档，我今天也遇到了。

对 flowerwrong 回复

建议先学习配置ssh连接自己服务器，github，bitbucket. 再回头就简单多了三年前... 还没接触太多服务器.😅
