SaltStack管理工具允许管理员对多个操作系统创建一个一致的管理系统

实验环境准备

实验步骤

一、主服务器——控制节点

安装epel源并安装控制端

yum install -y epel-release  //安装epel源

yum -y install salt-master   //安装控制端

修改控制端主配置文件

vi /etc/salt/master
//修改如下：
15行 interface: 192.168.142.172   //监听地址
215行 auto_accept: True        //避免要运行salt-key来确认证书认证
416行 file_roots:
          base:
          - /srv/salt           //saltstack文件根目录位置，目录需要手动进行创建
710行组分类：（这里实验环境只有一台客户端，仅设置一个即可）
nodegroups:
  group1: ‘web01.saltstack.com‘

552行 pillar_opts: True        //开启pillar功能，同步文件功能
529行 
pillar_roots:
          base:
          - /srv/pillar         //pillar的主目录，需要手动进行创建

建立salt&pillar目录

mkdir /srv/salt
mkdir /srv/pillar

启动服务并关闭核心防护功能

systemctl start salt-master
systemctl enable salt-master
//关闭核心功能
setenforce 0

检测服务启动状况

netstat -anpt | egrep ‘4505|4506‘
//4505为salt的消息发布专用端口；
//4506为客户端与服务端通信的端口
tcp        0      0 192.168.142.172:4505    0.0.0.0:*               LISTEN      13692/python
tcp        0      0 192.168.142.172:4506    0.0.0.0:*               LISTEN      13704/python
tcp        0      0 192.168.142.172:4506    192.168.142.110:36688   ESTABLISHED 13704/python
tcp        0      0 192.168.142.172:4505    192.168.142.110:57042   ESTABLISHED 13692/python

二、从服务器——被控制节点

安装epel源并安装被控制端

yum install -y epel-release  //安装epel源

yum -y install salt-minion   //安装被控制端

修改被控端配置文件

vi /etc/salt/minion
//修改配置如下：
16行 master: 192.168.172.142     //指定主控端IP
78行 id: web01.saltstack.com     //指定被控端主机名

启动服务

//启动被控端服务
systemctl start salt-minion

在主控端进行检查

//在主控端测试与被控端的通信状态（*号代表所有被控主机）
salt ‘*‘ test.ping
web01.saltstack.com:
    True

//检查密钥情况
salt-key -L
Accepted Keys:
web01.saltstack.com
Denied Keys:
Unaccepted Keys:
web01.saltstack.com
Rejected Keys:

注意：

检查时出现以下情况：
Salt request timed out. The master is not responding. If this error persists after verifying the master is up, worker_threads may need to be increased.
请自行检查配置文件格式或者重启服务器。

三、批量部署Apache

以下所有操作均在master端进行

cd /srv/salt/
vim top.sls
//按下图进行添加
base:
  ‘*‘:
    - apache
//在所有的客户端执行apache模块

vim apache.sls
//按下图进行添加
apache-service:
  pkg.installed:
    - names:
      - httpd
      - httpd-devel
  service.running:
    - name: httpd
    - enable: True

//重启服务
systemctl restart salt-master.service

//执行批量部署命令
salt ‘*‘ state.highstate
//执行完成后出现以下信息即为成功
web01.saltstack.com:

四、检查试验结果

web01：

[ ~]# rpm -q httpd
httpd-2.4.6-90.el7.centos.x86_64
[ ~]# netstat -ntap | grep 80
tcp6       0      0 :::80                   :::*                  LISTEN      6
