CentOS 8.2上安装部署SaltStack Master和 Minion

在本文中,您将学习如何在CentOS 8上安装SaltStack Master和 SaltStack Minion。

环境规格:

SaltStack Master配置

  • CPU -3.4 GHz(2核)

  • 内存-4 GB

  • 储存空间-50 GB

  • 作业系统-CentOS 8.2

  • 主机名– saltstack-master.lianglab.cn

    SaltStack Master和Minion hostname修改

    [root@Master yum.repos.d]# hostnamectl set-hostname saltstack-master.lianglab.cn
    [root@Minion yum.repos.d]# hostnamectl set-hostname saltstack-minion.lianglab.cn
    
    

    SaltStack Master和Minion hosts修改

    [root@saltstack-master yum.repos.d]# cat /etc/hosts
    127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    192.168.6.175 saltstack-master.lianglab.cn
    192.168.6.190 saltstack-minion.lianglab.cn
    
    
    [root@saltstack-minion ~]# cat  /etc/hosts
    127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    192.168.6.175 saltstack-master.lianglab.cn
    192.168.6.190 saltstack-minion.lianglab.cn
    
    

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。(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.lianglab.cn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。

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.saltstack.com/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

[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.lianglab.cn

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.

[root@saltstack-master yum.repos.d]# netstat -anplt| grep 45
tcp        0      0 0.0.0.0:4505            0.0.0.0:*               LISTEN      320474/python3.6

第七步:SaltStack Master配置CentOS 8防火墙

SaltStack master使用默认端口4505/tcp4506/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.lianglab.cn
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.lianglab.cn
Proceed? [n/Y] y
Key for minion saltstack-master.lianglab.cn accepted.
[root@saltstack-master ~]# 

在所有SaltStack奴才上执行ping命令。

[root@saltstack-master ~]# salt '*' test.ping
saltstack-master.lianglab.cn:
    True
[root@saltstack-master ~]# 

检查所有SaltStackd当前的版本。

[root@saltstack-master ~]# salt '*' test.version
saltstack-master.lianglab.cn:
    3002.2

如何在CentOS 8上安装SaltStack minion。

第九步:什么是SaltStack Minion

SaltStackSalt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.lianglab.cn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。

第十二步:CentOS 8上安装SaltStack官方Yum存储库

尽管SaltStack软件包可通过EPEL(企业Linux的额外软件包) yum存储库获得。但是,如果您想安装最新版本的SaltStack软件包,则必须按照以下步骤安装SaltStack官方yum存储库。

[root@saltstack-minion ~]# wget https://repo.saltstack.com/py3/redhat/salt-py3-repo-latest.el8.noarch.rpm

[root@saltstack-minion ~]# dnf -y install  salt-py3-repo-latest.el8.noarch.rpm

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.lianglab.cn

其中saltstack-master.lianglab.cn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PuTTYroot用户身份与saltstack-master.lianglab.cn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.lianglab.cn
Denied Keys:
Unaccepted Keys:
saltstack-minion.lianglab.cn
Rejected Keys:
[root@saltstack-master ~]# 

您会看到,有一个不可接受的密钥,即saltstack-minion.lianglab.cn。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.lianglab.cn
Proceed? [n/Y] y
Key for minion saltstack-minion.lianglab.cn 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.lianglab.cn上远程安装Apache Web服务器。

[root@saltstack-master ~]# salt 'saltstack-minion.lianglab.cn' cmd.run 'dnf install -y httpd'
