1. pillor配置

vim /etc/salt/master
#pillar默认不开启，将参数设置为True
pillar_opts: True
#设置文件目录
pillar_roots:
  base:
    - /srv/salt/pillar

2. 在pillar目录下创建hostname.sls（ip和主机名的键值对）

cat pillar/hostname.sls
ip_hostname:
  172.16.1.12: web1

3.在pillar目录下创建top.sls

base:
  '*':
    - hostname

4. 在salt base目录下创建set-host.sls(默认目录：/srv/salt)

　　方式一：用cmd.run模块执行shell命令

{% set ip = salt['network.interface_ip']('eth0') %}
alter_hostname:
  cmd.run:
    - name: hostnamectl  set-hostname {{ pillar['ip_hostname'][ip] }}

　　方式二：用自带模块network.mod_hostname修改

{% set ip = salt['network.interface_ip']('eth0') %}
{% set ip_hostname = pillar['ip_hostname'] %}
{% set hostname = ip_hostname[ip] %}

mod_hostname:
  module.run:
    - name: network.mod_hostname
    - hostname: {{hostname}}

5.执行测试

　　方式一：

salt-ssh '*' state.sls set-hostname test=True

nginx_01:

    Function: cmd.run
