grains时saltstack组件中非常重要的组件之一,grains时saltstack记录minion的一些静态信息的组件,我们可以理解未grains记录着每台minion的一些常用属性,譬如cpu,内存,磁盘,网络信息等。
[root@master ~]# salt ‘slave‘ grains.ls //查看grains记录的信息 slave: - SSDs - biosreleasedate - biosversion - cab_u - cabinet - cpu_flags - cpu_model - cpuarch - deployment - domain - fqdn - fqdn_ip4 - fqdn_ip6 - gpus - host - hwaddr_interfaces - id - init - ip4_interfaces - ip6_interfaces - ip_interfaces - ipv4 - ipv6 - kernel - kernelrelease - locale_info - localhost - lsb_distrib_codename - lsb_distrib_id - lsb_distrib_release - machine_id - manufacturer - master - mdadm - mem_total - myname - nodename - num_cpus - num_gpus - os - os_family - osarch - oscodename - osfinger - osfullname - osmajorrelease - osrelease - osrelease_info - path - productname - ps - pythonexecutable - pythonpath - pythonversion - role - roles - saltpath - saltversion - saltversioninfo - selinux - serialnumber - server_id - shell - virtual - web - zmqversion 若查看grains记录的具体的值: [root@master ~]# salt ‘slave‘ grains.items slave: ---------- SSDs: biosreleasedate: 07/31/2013 .......... biosversion: Intel(R) Core(TM) i3-3110M CPU @ 2.40GHz cpuarch: i686 deployment: datacenter4 domain: fq VMware, Inc. num_gpus: 1 os: CentOS os_family: RedHat
在实际的应用中,我们可以根据自己的需求定制一些grains,可采用如下的方法:
1:通过minion的设置定义;
这种方法就是修改minion的配置文件,把配置文件“default_include: minion.d/*.conf”前的注释去掉,然后在默认的目录中写入grains脚本。
[root@slave ~]# cat /etc/salt/minion.d/grains.conf grains: roles: - webserver - memcache deployment: datacenter4 cabinet: 13 cab_u: 14-15
然后在master上运行一下:
[root@master ~]# salt ‘slave‘ grains.item roles slave: ---------- roles: - webserver - memcache [root@master ~]# salt ‘slave‘ grains.item deployment slave: ---------- deployment: datacenter4
