第一步：什么是SaltStack Master
SaltStack或Salt是基于Python的开源软件，用于基于事件的IT自动化，远程任务执行和配置管理。SaltStack支持“基础架构即代码”方法来进行数据中心系统和网络的部署和管理，配置自动化，SecOps编排，漏洞修复以及混合云控制。（由维基百科提供）
SaltStack Master是服务器节点，它是控制所有Salstack Minions的中央服务器。Saltstack Master拥有SaltStack奴才的清单和公钥，并对这些奴才执行远程执行。
第二步：更新SaltStack Master CentOS 8软件包
使用ssh工具以root用户身份与saltstack-master.连接。
将所有现有软件包更新为最新的可用版本。
[root@saltstack-master ~]# dnf update -y

我们的CentOS 8软件包已成功更新。
第三步：SaltStack Master上安装Python
SaltStack用Python编写，因此，它需要Python语言支持才能编译和执行SaltStack命令。
Python3在默认的CentOS AppStream中可用，因此，我们可以使用dnf命令安装它。
[root@saltstack-master src]# dnf install -y python3

Python 3.6已安装在CentOS 8服务器上。
第四步：CentOS 8上安装SaltStack官方Yum存储库
尽管可以通过EPEL（企业Linux的额外软件包） yum存储库获得SaltStack软件包。但是，如果要安装最新版本，则应安装SaltStack的官方yum存储库。
使用以下命令在CentOS 8上安装SaltStack官方yum存储库。
[root@saltstack-master yum.repos.d]# wget https://repo./py3/redhat/salt-py3-repo-latest.el8.noarch.rpm
[root@saltstack-master yum.repos.d]# dnf -y install salt-py3-repo-latest.el8.noarch.rpm

第五步：CentOS 8上安装SaltStack Master
我们添加了SaltStack yum存储库，现在我们可以使用dnf命令轻松安装SaltStack软件包的最新版本。
安装SaltStack主服务器所需的必要的SaltStack软件包。
[root@saltstack-master yum.repos.d]# dnf install -y salt-master salt-minion salt-ssh salt-syndic salt-cloud salt-api

[root@saltstack-master yum.repos.d]#
在这里，我们还将在SaltStack Master上安装salt- minion软件包，因为Minion会收集和发送SaltStack Master服务器的系统指标，即使在同一服务器上也是如此。请参考我们的下一篇文章，[如何在CentOS 8上安装SaltStack Minion]
第六步：CentOS 8上配置SaltStack Master
SaltStack的配置文件位于/etc/salt目录中。
默认配置足够安静，无法启动SaltStack Master服务器，但是我们需要在启动服务之前调整SaltStack Minion配置。
编辑SaltStack Minion配置文件。
[root@saltstack-master-01 ~]# vi /etc/salt/minion
在此文件中找到以下指令。
#master: salt
并用以下指令替换它。
master: saltstack-master.
master指令向SaltStack Minion告知正在使用的SaltStack Master服务器。SaltStack主主机名必须是可解析的。您可以通过使用本地DNS解析器（即/ etc / hosts文件）来执行此操作，也可以为网络配置权威的DNS服务器。
启用并启动SaltStack Master和Minion服务。
[root@saltstack-master yum.repos.d]# systemctl enable --now salt-master salt-minion
Created symlink /etc/systemd/system/multi-user.target.wants/salt-master.service → /usr/lib/systemd/system/salt-master.service.
Created symlink /etc/systemd/system/multi-user.target.wants/salt-minion.service → /usr/lib/systemd/system/salt-minion.service.

tcp 0 0 0.0.0.0:4506 0.0.0.0:* LISTEN 320480/python3.6
第七步：SaltStack Master配置CentOS 8防火墙
SaltStack master使用默认端口4505/tcp和4506/tcp。因此，我们需要允许传入流量进入CentOS 8防火墙中的这两个端口。
[root@saltstack-master yum.repos.d]# firewall-cmd --permanent --add-port={4505,4506}/tcp
success
[root@saltstack-master yum.repos.d]# firewall-cmd --reload
success
第八步：管理SaltStack公钥
初始连接时，SaltStack奴才将其公共密钥发送给SaltStack主服务器。主人必须接受此公钥，以允许Minion与SaltStack主人进行通信。
列出所有SaltStack公共密钥。
[root@saltstack-master ~]# salt-key -L
Accepted Keys:
Denied Keys:
Unaccepted Keys:
saltstack-master.
Rejected Keys:
[root@saltstack-master ~]#
当前，只有一个不接受的公共密钥。使用以下命令接受此公钥。
[root@saltstack-master ~]# salt-key -A
The following keys are going to be accepted:
Unaccepted Keys:
saltstack-master.
Proceed? [n/Y] y
Key for minion saltstack-master. accepted.
[root@saltstack-master ~]#
在所有SaltStack奴才上执行ping命令。
[root@saltstack-master ~]# salt '*' test.ping
saltstack-master.:
True
[root@saltstack-master ~]#
检查所有SaltStackd当前的版本。
[root@saltstack-master ~]# salt '*' test.version
saltstack-master.:
3002.2
如何在CentOS 8上安装SaltStack minion。
第九步：什么是SaltStack Minion
SaltStack或Salt是基于Python的开源软件，用于基于事件的IT自动化，远程任务执行和配置管理。SaltStack支持“基础架构即代码”方法来进行数据中心系统和网络的部署和管理，配置自动化，SecOps编排，漏洞修复以及混合云控制。（礼貌：维基百科）
SaltStack minion是安装在受管节点上的代理软件，用于在该节点上执行命令并将其报告回SaltStack主服务器。
第十步：更新SaltStack MinionCentOS 8软件包
使用ssh工具以root用户身份与saltstack-minion.连接。
最佳做法是在安装新组件之前更新CentOS 8上的软件包。因此，执行以下dnf命令来更新所有CentOS 8软件包。
[root@saltstack-minion ~]# dnf update -y

第十一步：SaltStack Minion上安装Python
SaltStack是基于Python的软件，因此它需要Python语言支持才能编译和执行SaltStack命令。
Python 3.6在默认的CentOS 8 AppStream中可用，因此，我们可以使用dnf命令轻松安装它。

[root@saltstack-minion ~]#
第十四步：CentOS 8上配置SaltStack Minion
SaltStack minion的默认配置可以正常工作，除了我们需要告诉Minion有关SaltStack Master服务器。
因此，使用vim编辑器编辑SaltStack minion配置文件。
[root@saltstack-minion ~]# vi /etc/salt/minion
在其中找到以下指令。
#master: salt
并将上述指令替换为以下指令。
master: saltstack-master.
其中saltstack-master.是我们前面中配置的SaltStack主服务器。
启用并启动salt-minion服务。
[root@saltstack-minion ~]# systemctl enable --now salt-minion
Created symlink /etc/systemd/system/multi-user.target.wants/salt-minion.service → /usr/lib/systemd/system/salt-minion.service.
[root@saltstack-minion ~]#
第十五步：SaltStack主服务器中添加SaltStack Minion
使用PuTTY以root用户身份与saltstack-master.连接。
显示SaltStack主服务器已知的所有公共密钥的列表。
[root@saltstack-master ~]# salt-key -L
Accepted Keys:
saltstack-master.
Denied Keys:
Unaccepted Keys:
saltstack-minion.
Rejected Keys:
[root@saltstack-master ~]#
您会看到，有一个不可接受的密钥，即saltstack-minion.。这是我们的SaltStack的公钥。
使用以下命令接受此密钥。
[root@saltstack-master ~]# salt-key -A
The following keys are going to be accepted:
Unaccepted Keys:
saltstack-minion.
Proceed? [n/Y] y
Key for minion saltstack-minion. accepted.
[root@saltstack-master ~]#
第十六步：SaltStack Minion上的命令的远程执行安装HTTP服务
我们已添加到SaltStack Master库存中。我们现在可以执行命令了。
【1】为了演示，我们正在saltstack-minion.上远程安装Apache Web服务器。
[root@saltstack-master ~]# salt 'saltstack-minion.' cmd.run 'dnf install -y httpd'
