saltstack 一：安装之快速安装 bootstap script

salt bootstrap script 支持用户在各种系统中安装 master 和 minion，shell 脚本名称是 bootstrap-salt.sh，脚本里会有一系统的检查操作来确定操作系统的版本和类型，然后先把适当的方法安装 salt 二进制文件。bootstrap script 会安装最小数量的salt 依赖包，也就是尽可能的轻量化安装。它会在系统上存在了 salt 二进制文件后安装其他依赖的包。脚本地址  https://github.com/saltstack/salt-bootstrap

脚本安装支持大部分的 linux 发行版环境

使用 curl 通过 github 安装最新版本：

curl -o bootstrap-salt.sh -L https://bootstrap.saltstack.com
sudo sh bootstrap-salt.sh git develop

安装指定版本：

curl -o bootstrap-salt.sh -L https://bootstrap.saltstack.com
sudo sh bootstrap-salt.sh git v2015.8.8

安装 master：

curl -o bootstrap-salt.sh -L https://bootstrap.saltstack.com
sudo sh bootstrap-salt.sh -M -N git develop

使用 wget 安装：

wget -O bootstrap-salt.sh https://bootstrap.saltstack.com
sudo sh bootstrap-salt.sh

使用一行命令安装： 

curl -L https://bootstrap.saltstack.com | sudo sh

wget -O - https://bootstrap.saltstack.com | sudo sh

脚本安装命令选项：

$ sh bootstrap-salt.sh -h

  Usage :  bootstrap-salt.sh [options] <install-type> <install-type-args>

  Installation types:

    - stable [version] (ubuntu specific)
    - daily  (ubuntu specific)
    - testing (redhat specific)
    - git

  Examples:
    - bootstrap-salt.sh
    - bootstrap-salt.sh stable
    - bootstrap-salt.sh stable 2014.7
    - bootstrap-salt.sh daily
    - bootstrap-salt.sh testing
    - bootstrap-salt.sh git
    - bootstrap-salt.sh git develop
    - bootstrap-salt.sh git v0.17.0
    - bootstrap-salt.sh git 8c3fadf15ec183e5ce8c63739850d543617e4357

  Options:
  -h  Display this message # 显示帮助
  -v  Display script version # 显示脚本版本
  -n  No colours. 
  -D  Show debug output. # 显示debug输出
  -c  Temporary configuration directory
  -g  Salt repository URL. (default: git://github.com/saltstack/salt.git) # 指定salt repo 地址
  -G  Instead of cloning from git://github.com/saltstack/salt.git, clone from https://github.com/saltstack/salt.git (Usually necessary on systems which have the regular git protocol port blocked, where https usually is not)
  -k  Temporary directory holding the minion keys which will pre-seed
      the master.
  -s  Sleep time used when waiting for daemons to start, restart and when checking
      for the services running. Default: 3
  -M  Also install salt-master # 总是安装 master
  -S  Also install salt-syndic 
  -N  Do not install salt-minion # 总是安装 minion
  -X  Do not start daemons after installation
  -C  Only run the configuration function. This option automatically
      bypasses any installation.
  -P  Allow pip based installations. On some distributions the required salt
      packages or its dependencies are not available as a package for that
      distribution. Using this flag allows the script to use pip as a last
      resort method. NOTE: This only works for functions which actually
      implement pip based installations.
  -F  Allow copied files to overwrite existing(config, init.d, etc)
  -U  If set, fully upgrade the system prior to bootstrapping salt
  -K  If set, keep the temporary files in the temporary directories specified
      with -c and -k.
  -I  If set, allow insecure connections while downloading any files. For
      example, pass '--no-check-certificate' to 'wget' or '--insecure' to 'curl'
  -A  Pass the salt-master DNS name or IP. This will be stored under
      ${BS_SALT_ETC_DIR}/minion.d/99-master-address.conf
  -i  Pass the salt-minion id. This will be stored under
      ${BS_SALT_ETC_DIR}/minion_id
  -L  Install the Apache Libcloud package if possible(required for salt-cloud)
  -p  Extra-package to install while installing salt dependencies. One package
      per -p flag. You're responsible for providing the proper package name.
  -d  Disable check_service functions. Setting this flag disables the
      'install_<distro>_check_services' checks. You can also do this by
      touching /tmp/disable_salt_checks on the target host. Defaults ${BS_FALSE}
  -H  Use the specified http proxy for the installation
  -Z  Enable external software source for newer ZeroMQ(Only available for RHEL/CentOS/Fedora/Ubuntu based distributions)
  -b  Assume that dependencies are already installed and software sources are set up.
      If git is selected, git tree is still checked out as dependency step.
