自动化推送

cd /srv/salt/
mkdir _grains
cd _grains/
vim my_grains.py
#!/usr/bin/env python
def my_grains():
    grains = {}
    grains['hello'] = 'world'
    grains['salt'] = 'stack'
    return grains
salt server10 saltutil.sync_grains

在server10上查看

查询推送信息

salt ‘*’ grains.item hello
salt ‘*’ grains.item salt

vim /etc/salt/master
mkdir /srv/pillar
cd /srv/pillar
mkdir web
cd web/
vim install.sls
{% if grains['fqdn'] == 'server10' %}
webserver: httpd
{% elif grains['fqdn'] == 'server8' %}
webserver: nginx
{% endif %}
vim top.sls
base:
  '*':
    - web.install
/etc/init.d/salt-master restart
salt '*' saltutil.refresh_pillar

查看

salt 'server10' pillar.items
salt 'server8' pillar.items
salt '*' pillar.items

salt -G 'roles:apache' test.ping
salt -G 'roles:nginx' test.ping

salt -I 'webserver:nginx' test.ping
salt -I 'webserver:httpd' test.ping

saltstack的自动化推送更改配置文件

方法一

cd /srv/salt/httpd/
vim install.sls
/etc/httpd/conf/httpd.conf:
  file.managed:
    - source: salt://httpd/files/httpd.conf
    - mode: 664
    - user: root
    - template: jinja    # 必须导入这个模板
    - context:
      bind: 172.25.11.9
      port: 80
vim /srv/salt/httpd/files/httpd.conf
salt server10 state.sls httpd.install

方法二

cd /srv/salt/httpd/
vim lib.sls
{% set port = 80 %}
在/srv/salt/httpd/files/httpd.conf的文件首行写入
{% from 'httpd/lib.sls' import port with context %}
salt server10 state.sls httpd.install

方法三

cd /srv/salt/httpd/
vim install.sls

vim /srv/salt/httpd/files/httpd.conf
注释掉首行（最好删除）
Listen {{ grains['ipv4'][-1] }}:{{ port }}   #  截取ipv4列表的最后一个元素

推送 salt server10 state.sls httpd.install

方法四

cd /srv/salt/httpd/
vim /srv/pillar/web/install.sls
{% if grains['fqdn'] == 'server10' %}
webserver: httpd
bind: 172.25.11.10
port: 9090
{% elif grains['fqdn'] == 'server8' %}
webserver: nginx
{% endif %}

vim install.sls
/etc/httpd/conf/httpd.conf:
  file.managed:
    - source: salt://httpd/files/httpd.conf
    - mode: 664
    - user: root
    - template: jinja
    - context:
      bind: {{ pillar['bind'] }}
      port: {{ pillar['port'] }}

vim files/httpd.conf
Listen {{ pillar['bind'] }}:{{ pillar['port'] }}

salt server10 state.sls httpd.install
