參考saltStack官方文檔
ON THE SALT MASTER
Run these commands on the system that you want to use as the central management point.
curl -L https://bootstrap.saltstack.com -o install_salt.sh
sudo sh install_salt.sh -P -M
Your Salt master can manage itself, so a Salt minion is installed along with the Salt master. If you do not want to install the minion, also pass the -N option.ON EACH SALT MINION
Run these commands on each system that you want to manage using Salt.
curl -L https://bootstrap.saltstack.com -o install_salt.sh
sudo sh install_salt.sh -P實戰配置服務器如下
master 192.168.0.120 centos120
node1 192.168.0.121 centos121
node2 192.168.0.122 centos122以上三臺服務均關閉selinux ,firewalld,設置/etc/hosts ，也就是它們可以hostname相互訪問，且可以訪問互聯網，這些簡單操作就不在這里展示步驟了。
1.下面開始安裝

[root@centos121 ~]# 同理centos122節點minion，到此處minion 端安裝完成。
3.下面開始配置
配置之前需要了解的知識點：
saltstack簡單介紹
Saltstack是一種全新的基礎設施管理方式，是一個服務器基礎架構集中化管理平臺，幾分鐘內便可運行起來，速度夠快，服務器之間秒級通訊，擴展性好，很容易批量管理上萬臺服務器，顯著降低人力與運維成本；它具備配置管理、遠程執行、監控等功能，一般可以理解為簡化版的puppet和加強版的func；通過部署SaltStack環境，可以在成千上萬臺服務器上做到批量執行命令，根據不同業務特性進行配置集中化管理、分發文件、采集服務器數據、操作系統基礎及軟件包管理等，SaltStack是運維人員提高工作效率、規范業務配置與操作的利器。SaltStack基于Python語言實現，結合輕量級消息隊列（ZeroMQ）（SaltStack的通信模式總共分為2種模式：ZeroMQ、REAT，鑒于REAT目前還不是太穩定，通常會選擇ZeroMQ模式）與Python第三方模塊（Pyzmq、PyCrypto、Pyjinjia2、python-msgpack和PyYAML等）構建。
Saltstack運行模式：
Local：本地,一臺機器玩，不建議。
Master/Minion：通過server/agent的方式進行管理，效率很高（批量管理1000臺機器，25秒搞定）。
Salt SSH：通過SSH方式進行管理，效率相對來說比較低（批量管理1000臺機器，83秒搞定）。
Saltstack三大功能：
遠程執行（執行遠程命令）
配置管理（狀態管理）
云管理
Saltstack特征：
1）部署簡單、方便；
2）支持大部分UNIX/Linux及Windows環境；
3）主從集中化管理；
4）配置簡單、功能強大、擴展性強；
5）主控端（master）和被控端（minion）基于證書認證，安全可靠；
6）支持API及自定義模塊，可通過Python輕松擴展。
Master與Minion認證：
1）minion在第一次啟動時，會在/etc/salt/pki/minion/（該路徑在/etc/salt/minion里面設置）下自動生成minion.pem（private key）和 minion.pub（public key），然后將 minion.pub發送給master。
2）master在接收到minion的public key后，通過salt-key命令accept minion public key，這樣在master的/etc/salt/pki/master/minions下的將會存放以minion id命名的 public key，然后master就能對minion發送指令了。
Master與Minion的連接：
1）SaltStack master啟動后默認監聽4505和4506兩個端口。4505（publish_port）為saltstack的消息發布系統，4506（ret_port）為saltstack客戶端與服務端通信的端口。如果使用lsof 查看4505端口，會發現所有的minion在4505端口持續保持在ESTABLISHED狀態。
2）minion與master之間的通信模式如下：
現在開始配置，
先查看服務端安裝了那些文件：

[root@centos120 salt]# saltstack之grains介紹：
GRAINS 組件是saltstack中非常重要的一個組件，其主要用于記錄Minion的一些靜態信息，如比：CPU、內存、磁盤、網絡等。grains信息是每次客戶端啟動后自動上報給master的，一旦這些靜態信息發生改變需要重啟minion 或者 重新同步下 grains。
grains 是在minion啟動收集到的一些信息，比如操作系統的類型，網卡IP,內存版本，CPU信息等。

[root@centos121 ~]# 創建執行命令的配置文件：
[root@centos120 salt]# vi cmd.sls
[root@centos120 salt]# cat cmd.sls
cmd_test:
cmd.run:
- unless: test -f /tmp/gnu.index
- names:
- touch /tmp/cmdfile.index
- mkdir /tmp/cmd
- user: root
[root@centos120 salt]#注意：unless: 表示若 /tmp/gnu.index文件不存在，也就是結果為True則執行-name后面的命令，為false則不執行；還可以使用 onlyif 表示若 /tmp/gnu.index文件存在，則執行后面的命令；兩者正好相反。
