自动化运转之SaltStack实行

2019年12月23日 admin 0 Comments

                           自动化运维之SaltStack实践

1.1、环境

linux-node1(master服务端) 192.168.0.15
linux-node2(minion客户端) 192.168.0.16

1.2、SaltStack三种运行模式介绍

Local 本地
Master/Minion 传统运行方式(server端跟agent端)
Salt SSH SSH

1.3、SaltStack三大功能 ●远程执行 ●配置管理 ●云管理
1.4、SaltStack安装基础环境准备

[[email protected]
~]# cat /etc/redhat-release  ##查看系统版本 CentOS release 6.7
(Final)
[[email protected]
~]# uname -r ##查看系统内核版本 2.6.32-573.el6.x86_64
[[email protected]
~]# getenforce ##查看selinux的状态 Enforcing
[[email protected]
~]# setenforce 0 ##关闭selinux
[[email protected]
~]# getenforce   Permissive
[[email protected]
~]# /etc/init.d/iptables stop
[[email protected]
~]# /etc/init.d/iptables stop
[[email protected]
~]# ifconfig eth0|awk -F ‘[: ]+’ ‘NR==2{print $4}’ ##过滤Ip地址
192.168.0.15
[[email protected]
~]# hostname ##查看主机名 linux-node1.zhurui.com
[[email protected]
yum.repos.d]# wget -O /etc/yum.repos.d/epel.repo
澳门游戏平台大全， 
##安装salt必须使用到epel源  1.4、安装Salt 服务端：
[[email protected]
yum.repos.d]# yum install -y salt-master salt-minion
##salt-master包跟salt-minion包
[[email protected]
yum.repos.d]# chkconfig salt-master on  ##加入到开机自动启动
[[email protected]
yum.repos.d]# chkconfig salt-minion on  ##加入到开机自动启动
[[email protected]
yum.repos.d]# /etc/init.d/salt-master start   ##启动salt-master
Starting salt-master daemon:                                   [  OK
 ] 启动到这里需要修改minion配置文件，才能启动salt-minion服务
[[email protected]
yum.repos.d]# grep ‘^[a-z]’ /etc/salt/minion    master: 192.168.0.15
 ##指定master主机
[[email protected]
yum.repos.d]# cat /etc/hosts 192.168.0.15 linux-node1.zhurui.com
linux-node1  ##确认主机名是否解析 192.168.0.16 linux-node2.zhurui.com
linux-node2 解析结果：

  1. [[email protected]-node1 yum.repos.d]# ping linux-node1.zhurui.com
  2. PING linux-node1.zhurui.com (192.168.0.15)56(84) bytes of data.

[[email protected]
yum.repos.d]# /etc/init.d/salt-minion start  ##启动minion客户端
Starting salt-minion daemon:                               [  OK  ]
[[email protected]
yum.repos.d]# 客户端：
[[email protected]
~]# yum install -y salt-minion  ##安装salt-minion包，相当于客户端包
[[email protected]
~]# chkconfig salt-minion on  ##加入开机自启动
[[email protected]
~]# grep ‘^[a-z]’ /etc/salt/minion   ##客户端指定master主机
master: 192.168.0.15
[[email protected]
~]# /etc/init.d/salt-minion start  ##接着启动minion Starting
salt-minion daemon:                               [  OK  ]
1.5、Salt秘钥认证设置 1.5.1使用salt-kes -a
linux*命令之前在目录/etc/salt/pki/master目录结构如下
澳门游戏平台大全 1
澳门游戏平台大全 2
1.5.2使用salt-kes -a
linux*命令将秘钥通过允许，随后minions_pre下的文件会转移到minions目录下

  1. [[email protected]-node1 minion]# salt-key -a linux*
  2. The following keys are going to be accepted:
  3. UnacceptedKeys:
  4. linux-node1.zhurui.com
  5. linux-node2.zhurui.com
  6. Proceed?[n/Y] Y
  7. Keyfor minion linux-node1.zhurui.com accepted.
  8. Keyfor minion linux-node2.zhurui.com accepted.
  9. [[email protected]-node1 minion]# salt-key
  10. AcceptedKeys:
  11. linux-node1.zhurui.com
  12. linux-node2.zhurui.com
  13. DeniedKeys:
  14. UnacceptedKeys:
  15. RejectedKeys:

澳门游戏平台大全 3
1.5.3此时目录机构变化成如下：
澳门游戏平台大全 4
1.5.4并且伴随着客户端/etc/salt/pki/minion/目录下有master公钥生成
澳门游戏平台大全 5
1.6、salt远程执行命令详解 1.6.1 salt ‘*’ test.ping 命令
[[email protected]
master]# salt ‘*’ test.ping  ##salt命令
 test.ping的含义是，test是一个模块，ping是模块内的方法
linux-node2.zhurui.com:     True linux-node1.zhurui.com:     True
[[email protected]
master]# 
澳门游戏平台大全 6 1.6.2
 salt ‘*’ cmd.run ‘uptime’ 命令
澳门游戏平台大全 7
1.7、saltstack配置管理
1.7.1编辑配置文件/etc/salt/master,将file_roots注释去掉
澳门游戏平台大全 8
1.7.2接着saltstack远程执行如下命令
[[email protected]
master]# ls /srv/
[[email protected]
master]# mkdir /srv/salt
[[email protected]
master]# /etc/init.d/salt-master restart Stopping salt-master daemon:
                              [  OK  ] Starting salt-master daemon:  
                              [  OK  ]
[[email protected]
salt]# cat apache.sls   ##进入到/srv/salt/目录下创建
澳门游戏平台大全 9
[[email protected]
salt]# salt ‘*’ state.sls apache  ##接着执行如下语句
接着会出现如下报错：
澳门游戏平台大全 10
便捷apache.sls文件添加如下：
澳门游戏平台大全 11
最后成功如下：

  1. [[email protected]-node1 salt]# salt '*' state.sls apache

2.1.5 也可以通过创建新的配置文件/etc/salt/grains文件来配置规则

[[email protected]
salt]# cat /etc/salt/grains  web: nginx
[[email protected]
salt]# /etc/init.d/salt-minion restart
 ##修改完配置文件以后需要重启服务 Stopping salt-minion daemon:

salt]# salt -G web:nginx cmd.run ‘w’

1.收集底层系统信息 2、远程执行里面匹配minion 3、top.sls里面匹配minion  
2.1.5 也可以/srv/salt/top.sls配置文件匹配minion

2.2、SaltStack之Pillar数据系统 2.2.1
首先在master配置文件552行打开pillar开关  
[[email protected]
salt]# grep ‘^[a-z]’ /etc/salt/master  file_roots: pillar_opts:
True
[[email protected]
salt]# /etc/init.d/salt-master restart   ##重启master Stopping
salt-master daemon:                               [  OK  ] Starting
salt-master daemon:                                 [  OK  ]
[[email protected]
salt]# salt ‘*’ pillar.items  ##使用如下命令验证 截图如下：
澳门游戏平台大全 20
[[email protected]
salt]# grep ‘^[a-z]’ /etc/salt/master 529 pillar_roots:
 ##打开如下行 530   base: 531     – /srv/pillar 截图如下：
澳门游戏平台大全 21
[[email protected]
salt]# mkdir /srv/pillar
[[email protected]
salt]# /etc/init.d/salt-master restart  ##重启master Stopping
salt-master daemon:                               [  OK  ] Starting
salt-master daemon:                                 [  OK  ]
[[email protected]
salt]# vim /srv/pillar/apache.sls
[[email protected]
salt]# cat /srv/pillar/apache.sls {%if grains[‘os’] == ‘CentOS’ %}
apache: httpd {% elif grains[‘os’] == ‘Debian’ %} apache: apache2 {%
endif %}
[[email protected]
salt]#  截图如下：
澳门游戏平台大全 22
接着指定哪个minion可以看到：
[[email protected]
salt]# cat /srv/pillar/top.sls  base:   ‘*’:     – apache
澳门游戏平台大全 23
 
[[email protected]
salt]# salt ‘*’ pillar.items ##修改完成以后使用该命令验证
linux-node1.zhurui.com:     ———-     apache:         httpd
linux-node2.zhurui.com:     ———-     apache:         httpd
截图如下：
澳门游戏平台大全 24 2.2.1
使用Pillar定位主机

报错处理：
[[email protected]
salt]# salt ‘*’ saltutil.refresh_pillar  ##需要执行刷新命令
linux-node2.zhurui.com:     True linux-node1.zhurui.com:     True
[[email protected]
salt]#  截图如下：
澳门游戏平台大全 26

[[email protected]
salt]# salt -I ‘apache:httpd’ test.ping linux-node1.zhurui.com:

2.3、SaltStack数据系统区别介绍

名称 存储位置 数据类型 数据采集更新方式 应用
Grains minion端 静态数据 minion启动时收集，也可以使用saltutil.sync_grains进行刷新。 存储minion基本数据，比如用于匹配minion,自身数据可以用来做资产管理等。
Pillar master端 动态数据 在master端定义，指定给对应的minion，可以使用saltutil.refresh_pillar刷新 存储Master指定的数据，只有指定的minion可以看到，用于敏感数据保存。
