    添加新用户

    在服务器添加一个新的用户,用户名为 deploy教程

    • 执行命令sudo adduser 用户名

    • 按提示输入密码

    • 设置一些个人信息,可以直接按 enter 键,设为空

    • 添加权限

      在 root 用户下,打开/etc/sudoers文件

      #
      # This file MUST be edited with the 'visudo' command as root.
      #
      # Please consider adding local content in /etc/sudoers.d/ instead of
      # directly modifying this file.
      #
      # See the man page for details on how to write a sudoers file.
      #
      Defaults        env_reset
      Defaults        mail_badpass
      Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
      
      # Host alias specification
      
      # User alias specification
      
      # Cmnd alias specification
      
      # User privilege specification
      root    ALL=(ALL:ALL) ALL
      deploy  ALL=(ALL:ALL) ALL # 添加这一行,使deploy具有使用sudo的权限
      
      # Members of the admin group may gain root privileges
      %admin ALL=(ALL) ALL
      
      # Allow members of group sudo to execute any command
      %sudo   ALL=(ALL:ALL) ALL
      
      # See sudoers(5) for more information on "#include" directives:
      
      #includedir /etc/sudoers.d
      

    ruby 安装

    • 安装rbenv 教程来源
      sudo deploy回到 deploy 下

      git clone https://github.com/rbenv/rbenv.git ~/.rbenv
      # 用来编译安装 ruby
      git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
      # 用来管理 gemset, 可选, 因为有 bundler 也没什么必要
      git clone git://github.com/jamis/rbenv-gemset.git  ~/.rbenv/plugins/rbenv-gemset
      # 通过 rbenv update 命令来更新 rbenv 以及所有插件, 推荐
      git clone git://github.com/rkh/rbenv-update.git ~/.rbenv/plugins/rbenv-update
      # 使用 Ruby China 的镜像安装 Ruby, 国内用户推荐
      git clone git://github.com/AndorChen/rbenv-china-mirror.git ~/.rbenv/plugins/rbenv-china-mirror
      

      然后把下面的代码放到  ~/.bashrc  里

      export PATH="$HOME/.rbenv/bin:$PATH"
      eval "$(rbenv init -)"
      

      然后重开一个终端就可以执行 rbenv 了.

    • 安装 ruby

      rbenv install --list  # 列出所有 ruby 版本
      rbenv install 2.5.0     # 安装 2.5.0
      

      安转过程可能出现缺少依赖的错误,可参考这篇文章解决
      一般解决办法:

      sudo apt-get install autoconf bison build-essential libssl-dev libyaml-dev libreadline6 libreadline6-dev zlib1g zlib1g-dev
      
    • 验证安装是否成功

      rbenv versions               # 列出安装的版本
      rbenv version                # 列出正在使用的版本
      
    • 设置版本

      rbenv global 2.5.0      # 默认使用 2.5.0
      rbenv shell 2.5.0       # 当前的 shell 使用 2.5.0, 会设置一个 `RBENV_VERSION` 环境变量
      rbenv local jruby-1.7.3      # 当前目录使用 jruby-1.7.3, 会生成一个 `.rbenv-version` 文件
      
    • last

      rbenv rehash                 # 每当切换 ruby 版本和执行 bundle install 之后必须执行这个命令
      rbenv which irb              # 列出 irb 这个命令的完整路径
      rbenv whence irb             # 列出包含 irb 这个命令的版本
      
    • 安装bundle

      gem install bundle
      
    • 安装rails

      gem install rails
      
    • 安装 nodejs

      curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
      sudo apt-get install -y nodejs
      

    数据库

    使用 postgresql 数据库教程来源

    sudo apt-get install postgresql
    
    • 新建数据库用户

      sudo -i -u postgres  //切换到数据库的超级管理员
      psql                 //进入数据库控制台
      create user deploy with password 'xxxx'; //新建一个deploy用户,密码是xxx
      alter role deploy with createdb; //使deploy用户具有创建数据库的权限
      alter role deploy with login;//使deploy用户具有登录数据库的权限
      
    • 注意:

      在后面安装 pg gem 时,可能会出现You need to install postgresql-server-dev-X.Y for building a server-side extension or libpq-dev for building a client-side applic ation错误,依次执行:

      sudo apt-get install python-psycopg2
      sudo apt-get install libpq-dev
      

    nginx passenger 安装

    这里很详细了

    sudo apt-get install -y dirmngr gnupg
    sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7
    sudo apt-get install -y apt-transport-https ca-certificates
    sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger xenial main > /etc/apt/sources.list.d/passenger.list'
    sudo apt-get update
    sudo apt-get install -y nginx-extras passenger
    
    • passenger 的配置

      nginx 安装以后,打开/etc/nginx/passenger.conf会看到

      passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
      passenger_ruby /home/deploy/.rbenv/shims/ruby; //这里需要修改ruby的安装路径
      

      which ruby 可以查看 ruby 的路径

    Capistrano 配置原文教程

    • 安装必要的包

      group :development do
      gem 'capistrano'
      gem 'capistrano-bundler'
      gem 'capistrano-rails'
      gem 'capistrano-rbenv'
      # Add this if you're using rvm
      # gem 'capistrano-rvm'
      end
      
    • cap install

    • 我的 capfile 文件

      # Load DSL and set up stages
      require "capistrano/setup"
      
      # Include default deployment tasks
      require "capistrano/deploy"
      
      # Load the SCM plugin appropriate to your project:
      #
      # require "capistrano/scm/hg"
      # install_plugin Capistrano::SCM::Hg
      # or
      # require "capistrano/scm/svn"
      # install_plugin Capistrano::SCM::Svn
      # or
      require "capistrano/scm/git"
      install_plugin Capistrano::SCM::Git
      
      # Include tasks from other gems included in your Gemfile
      #
      # For documentation on these, see for example:
      #
      #   https://github.com/capistrano/rvm
      #   https://github.com/capistrano/rbenv
      #   https://github.com/capistrano/chruby
      #   https://github.com/capistrano/bundler
      #   https://github.com/capistrano/rails
      #   https://github.com/capistrano/passenger
      #
      # require "capistrano/rvm"
      require "capistrano/rbenv"
      # require "capistrano/chruby"
      require "capistrano/bundler"
      require "capistrano/rails/assets"
      require "capistrano/rails/migrations"
      require "capistrano/passenger"
      set :rbenv_type, :user
      set :rbenv_ruby, '2.5.0'
      
      # Load custom tasks from `lib/capistrano/tasks` if you have any defined
      Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }
      

      我的 deploy.rb 文件

      # config valid for current version and patch releases of Capistrano
      lock "~> 3.10.2"
      
      set :application, "script_blog"
      set :repo_url, "https://github.com/dccmmtop/script_blog.git"
      # Default branch is :master
      # ask :branch, `git rev-parse --abbrev-ref HEAD`.chomp
      
      # Default deploy_to directory is /var/www/my_app_name
      set :deploy_to, "/home/deploy/scrit_blog"
      
      # Default value for :format is :airbrussh.
      # set :format, :airbrussh
      
      # You can configure the Airbrussh format using :format_options.
      # These are the defaults.
      # set :format_options, command_output: true, log_file: "log/capistrano.log", color: :auto, truncate: :auto
      
      # Default value for :pty is false
      # set :pty, true
      
      # Default value for :linked_files is []
      # 在服务器<project-name>/share/config/ 下,要手动新建这两个文件,
      append :linked_files, "config/database.yml","config/secrets.yml"
      
      # Default value for linked_dirs is []
      append :linked_dirs, "log", "tmp/pids", "tmp/cache", "tmp/sockets", "public/system"
      
      # Default value for default_env is {}
      # set :default_env, { path: "/opt/ruby/bin:$PATH" }
      
      # Default value for local_user is ENV['USER']
      # set :local_user, -> { `git config user.name`.chomp }
      
      # Default value for keep_releases is 5
      # set :keep_releases, 5
      
      # Uncomment the following to require manually verifying the host key before first deploy.
      # set :ssh_options, verify_host_key: :secure
      

      注意append :linked_files, "config/database.yml","config/secrets.yml"

      database.ymlsecrets.yml是手动在,share/config/目录下新建的,一个是连接数据库的相关信息,一个是安全验证相关信息。我的部署目录是scriot_blog/ 就新建 script_blog/share/config/ 目录

      同时新建以上两个文件。

      database.yml

      production:
      adapter: postgresql
      pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
      timeout: 5000
      database: production_blog
      username: 'xxx'
      password: 'xxx'
      

      secrets.yml

      production:
      secret_key_base: xxxxxx
      

      其中secret_key_base的值是在本地项目下 执行rake secret 命令生成的。

    • deploy/production.rb

      # server-based syntax
      # ======================
      # Defines a single server with a list of roles and multiple properties.
      # You can define all roles on a single server, or split them:
      
      # server "39.108.138.149", user: "root", roles: %w{app db web}, my_property: :my_value
      server "xxxx服务器的ip", user: "deploy", roles: %w{app db web}
      # server "example.com", user: "deploy", roles: %w{app web}, other_property: :other_value
      # server "db.example.com", user: "deploy", roles: %w{db}
      # 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(/home/deploy/.ssh/id_rsa),
      port: xxx
      # forward_agent: false,
      # auth_methods: %w(password)
      }
      #
      # The server-based syntax can be used to override options:
      # ------------------------------------
      # server "example.com",
      #   user: "user_name",
      #     keys: %w(/home/user_name/.ssh/id_rsa),
      #     forward_agent: false,
      #     auth_methods: %w(publickey password)
      #     # password: "please use keys"
      #   }
