ruby-on-rails - Capistrano 在部署到生产环境时不创建 puma pid

Question

我有一个简单的 Rails 应用程序，我正尝试使用 Capistrano 将其部署到生产服务器，但在尝试创建 puma.pid 时它似乎失败了。

当我检查 puma.access.log 时，我看到以下内容，

/home/capin/.rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/uri/rfc3986_parser.rb:66:in `split': bad URI(is not URI?): unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock (URI::InvalidURIError)
    from /home/capin/.rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/uri/rfc3986_parser.rb:72:in `parse'
    from /home/capin/.rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/uri/common.rb:226:in `parse'
    from /home/capin/apps/Tshirt/shared/bundle/ruby/2.2.0/gems/puma-2.15.3/lib/puma/binder.rb:85:in `block in parse'
    from /home/capin/apps/Tshirt/shared/bundle/ruby/2.2.0/gems/puma-2.15.3/lib/puma/binder.rb:84:in `each'
    from /home/capin/apps/Tshirt/shared/bundle/ruby/2.2.0/gems/puma-2.15.3/lib/puma/binder.rb:84:in `parse'
    from /home/capin/apps/Tshirt/shared/bundle/ruby/2.2.0/gems/puma-2.15.3/lib/puma/runner.rb:119:in `load_and_bind'
    from /home/capin/apps/Tshirt/shared/bundle/ruby/2.2.0/gems/puma-2.15.3/lib/puma/single.rb:79:in `run'
    from /home/capin/apps/Tshirt/shared/bundle/ruby/2.2.0/gems/puma-2.15.3/lib/puma/cli.rb:215:in `run'
    from /home/capin/apps/Tshirt/shared/bundle/ruby/2.2.0/gems/puma-2.15.3/bin/puma:10:in `<top (required)>'
    from /home/capin/apps/Tshirt/shared/bundle/ruby/2.2.0/bin/puma:23:in `load'
    from /home/capin/apps/Tshirt/shared/bundle/ruby/2.2.0/bin/puma:23:in `<main>'

有人知道为什么 puma 会显示这个错误吗？如果需要，我可以发布更多配置文件。

# role-based syntax
# ==================

# Defines a role with one or multiple servers. The primary server in each
# group is considered to be the first unless any  hosts have the primary
# property set. Specify the username and a domain or IP for the server.
# Don't use `:all`, it's a meta role.

# role :app, %w{deploy@example.com}, my_property: :my_value
# role :web, %w{user1@primary.com user2@additional.com}, other_property: :other_value
# role :db,  %w{deploy@example.com}



# Configuration
# =============
# You can set any configuration variable like in config/deploy.rb
# These variables are then only loaded and set in this stage.
# For available Capistrano configuration variables see the documentation page.
# http://capistranorb.com/documentation/getting-started/configuration/
# Feel free to add new variables to customise your setup.



# Custom SSH Options
# ==================
# You may pass any option but keep in mind that net/ssh understands a
# limited set of options, consult the Net::SSH documentation.
# http://net-ssh.github.io/net-ssh/classes/Net/SSH.html#method-c-start
#
# Global options
# --------------

set :ssh_options, {
   keys: %w(/Users/capin/.ssh/id_rsa),
   forward_agent: true,
   auth_methods: %w(publickey password)
   # port: 4321,
  }

#  set :ssh_options, {
#    keys: %w(/home/rlisowski/.ssh/id_rsa),
#    forward_agent: false,
#    auth_methods: %w(password)
#  }
#
# The server-based syntax can be used to override options:
# ------------------------------------
# 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'

看起来你的 puma/capistrano 配置文件中有错误。我认为您将行 unix://#{shared_pa​​th}/tmp/sockets/#{fetch(:application)}-puma.sock 放入单配额而不是双配额，字符串插值不起作用:)

更新:检查你的 puma_bind 值，应该是

set :puma_bind, "unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock"

双重配额
