saltstack简单介绍和安装
saltstack是一个新的基础平台管理工具； C/S架构https://docs.saltstack.com/en/latest/topics/installation/index.html
优点：
1.安装、部署简单，可快速启动服务
2.可支撑管理上万台服务器的规模
3.传输数据基于ZeroMQ（轻量级消息队列），传输数据并发、快速
4.支持API及自定义模块，可以通过Python轻松扩展
依赖：
DEPENDENCIES
Salt should run on any Unix-like platform so long as the dependencies are met.
Python 2.6 >= 2.6 <3.0
msgpack-python - High-performance message interchange format
YAML - Python YAML bindings
Jinja2 - parsing Salt States (configurable in the master settings)
MarkupSafe - Implements a XML/HTML/XHTML Markup safe string for Python
apache-libcloud - Python lib for interacting with many of the popular cloud service providers using a unified API
Requests - HTTP library
Tornado - Web framework and asynchronous networking library
futures - Backport of the concurrent.futures package from Python 3.2
端口：
4505：为salt的消息发布专用端口 //在monion端ss -e会发现一直和master的4505端口保持链接，用于和客户端的长连接,保证master端和minion端的消息通信正常
4506：用于文件服务的传输端口，进行认证等

salt-master服务端主机：
详细安装请参考官网，正常情况yum是可以安装saltstack的、
服务器端安装master和minion：
yum install salt-master
yum install salt-minion
查看服务端安装了什么：
# rpm -ql salt-master
/etc/salt/master
/etc/salt/master.d
/etc/salt/pki/master
/usr/bin/salt
/usr/bin/salt-cp
/usr/bin/salt-key
/usr/bin/salt-master
/usr/bin/salt-run
/usr/bin/salt-unity
/usr/lib/systemd/system/salt-master.service
/usr/share/man/man1/salt-cp.1.gz
/usr/share/man/man1/salt-key.1.gz
/usr/share/man/man1/salt-master.1.gz
/usr/share/man/man1/salt-run.1.gz
/usr/share/man/man1/salt-unity.1.gz
/usr/share/man/man7/salt.7.gz
/var/log/salt/master
# rpm -ql salt-minion
/etc/salt/minion
/etc/salt/minion.d
/etc/salt/pki/minion
/etc/salt/proxy
/usr/bin/salt-call
/usr/bin/salt-minion
/usr/bin/salt-proxy
/usr/lib/systemd/system/salt-minion.service
/usr/share/man/man1/salt-call.1.gz
/usr/share/man/man1/salt-minion.1.gz
/usr/share/man/man1/salt-proxy.1.gz
/var/log/salt/minion
修改简单的配置：
vi /etc/salt/master
#interface: 0.0.0.0
改为
interface: 10.0.0.177 //10.0.0.177为服务器的本机地址
到此入门的安装配置就已经完毕，下面说minion端的安装配置了

客户端只安装minion包括hddcluster1、hddcluster2、hddcluster3、hddcluster4、salt-minion01：
yum install salt-minion
# rpm -ql salt-minion
/etc/rc.d/init.d/salt-minion
/etc/salt/minion
/etc/salt/minion.d
/etc/salt/pki/minion
/etc/salt/proxy
/usr/bin/salt-call
/usr/bin/salt-minion
/usr/bin/salt-proxy
/usr/share/man/man1/salt-call.1.gz
/usr/share/man/man1/salt-minion.1.gz
/usr/share/man/man1/salt-proxy.1.gz
/var/log/salt/minion
root@salt-minion01 ~]#
vim /etc/salt/minion
#master: salt
改为：
master: 10.0.0.177
