Grains基础:
• Grains是saltstack最重要的组件之一
• 存储minion端的基本信息,这些信息一般都是静态的,如CPU、内核、操作系统等
• Grains存储在minion本地
• 管理员可以在minion端进行grains值的修改,如增加、删除等
Grains基础应用
应用一： 获取minion端所有grains信息
# salt '随便一台主机名' grains.items 相当于python字典的items() 列出key value
#salt '随便一台主机名' grains.ls 只列出key
#salt '随便一台主机名' grains.get saltversion 获取某个key的value
• 通过grains.item获取minion端的fqdn信息
# salt '随便一台主机名' grains.item fqdn
[root@linux-node1 ~]# salt 'linux-node1.localdomain' grains.items

应用二
root@linux-node1 ~]# vim /srv/salt/base/web/apache.sls
apache-install:
pkg.installed:
- name: httpd
apache-service:
service.running:
- name: httpd
- enable: True
[root@linux-node1 ~]# vim /srv/salt/base/top.sls
base:
'os:CentOS':
- match: grain
- web.apache
[root@linux-node1 ~]# salt '*' state.highstate
应用三 通过minion的配置文件定义grains
[root@web1 ~]# vim /etc/salt/minion
grains:
web:
apache
[root@web1 ~]# systemctl restart salt-minion.service
[root@web2 ~]# vim /etc/salt/minion
grains:
web:
nginx
[root@web2 ~]# systemctl restart salt-minion.service
[root@sm ~]# salt '*' saltutil.sync_grains
web1:
db1:
cache:
web2:
db2:
[root@sm ~]# salt -G 'web:apache' test.ping
web1:
True
[root@sm ~]# salt -G 'web:nginx' test.ping
web2:
True
[root@sm ~]# salt 'web1' grains.item web
web1:
----------
web:
apache
[root@sm ~]# salt 'web2' grains.item web
web2:
----------
web:
nginx
应用四 在minion的/etc/salt下创建一个grains文件自定义grains键值对
例子一
[root@linux-node2 ~]# vim /etc/salt/grains
haha: linux-node1
[root@linux-node2 ~]# systemctl restart salt-minion
[root@linux-node1 ~]# salt '*' grains.get haha
linux-node1.localdomain:
linux-node2.localdomain:
linux-node1
例子二
[root@linux-node2 ~]# vim /etc/salt/grains
haha: linux-node1
[root@linux-node1 ~]# salt '*' saltutil.sync_grains 不需要重启就可以获取值 相对于例子一
[root@linux-node1 ~]# salt '*' grains.get haha
linux-node1.localdomain:
linux-node2.localdomain:
linux-node1
