salt匹配规则有多种，对应各种不同的场景，相关参数如下图所示。现总结如下：
1、正则匹配
[root@salt-master ~]# salt -E 'salt-minion(01|02).contoso.com' test.pingsalt-minion01.contoso.com: Truesalt-minion02.contoso.com: True[root@salt-master ~]# salt -E 'salt-minion0[1-2].contoso.com' test.pingsalt-minion02.contoso.com: Truesalt-minion01.contoso.com: True
2、列表匹配
[root@salt-master ~]# salt -L 'salt-minion01.contoso.com,salt-minion02.contoso.com' test.pingsalt-minion01.contoso.com: Truesalt-minion02.contoso.com: True
3、Grains匹配
saltstack Grains项可以通过如下命令获取：
root@salt-master ~]# salt 'salt-minion01.contoso.com' grains.itemssalt-minion01.contoso.com: ---------- SSDs: biosreleasedate: 07/02/2015 biosversion: 6.00 cpu_flags: - fpu - vme - mtrr - sse - sse2 - ssse3 .... cpu_model: Intel(R) Core(TM) i7-6820HQ CPU @ 2.70GHz cpuarch: x86_64 domain: contoso.com fqdn: salt-minion01.contoso.com fqdn_ip4: - 192.168.49.101 fqdn_ip6: gpus: |_ ---------- model: SVGA II Adapter vendor: unknown host: salt-minion01 hwaddr_interfaces: ---------- eth0: 00:0c:29:f3:43:86 lo: 00:00:00:00:00:00 id: salt-minion01.contoso.com init: upstart ip4_interfaces: ---------- eth0: - 192.168.49.101 lo: - 127.0.0.1 ip6_interfaces: ---------- eth0: - fe80::20c:29ff:fef3:4386 lo: - ::1 ip_interfaces: ---------- eth0: - 192.168.49.101 - fe80::20c:29ff:fef3:4386 lo: - 127.0.0.1 - ::1 ipv4: - 127.0.0.1 - 192.168.49.101 ipv6: - ::1 - fe80::20c:29ff:fef3:4386 kernel: Linux kernelrelease: 2.6.32-431.el6.x86_64 locale_info: ---------- defaultencoding: UTF8 defaultlanguage: en_US detectedencoding: UTF-8 localhost: salt-minion01.contoso.com lsb_distrib_codename: Final lsb_distrib_id: CentOS lsb_distrib_release: 6.5 machine_id: ff172a920d48e1f109f755820000000a manufacturer: VMware, Inc. master: salt-master.contoso.com mdadm: mem_total: 980 nodename: salt-minion01.contoso.com num_cpus: 1 num_gpus: 1 os: CentOS os_family: RedHat osarch: x86_64 oscodename: Final osfinger: CentOS-6 osfullname: CentOS osmajorrelease: 6 osrelease: 6.5 osrelease_info: - 6 - 5 path: /sbin:/usr/sbin:/bin:/usr/bin productname: VMware Virtual Platform ps: ps -efH pythonexecutable: /usr/bin/python2.6 pythonpath: - /usr/bin - /usr/lib64/python26.zip - /usr/lib64/python2.6 - /usr/lib64/python2.6/plat-linux2 - /usr/lib64/python2.6/lib-tk - /usr/lib64/python2.6/lib-old - /usr/lib64/python2.6/lib-dynload - /usr/lib64/python2.6/site-packages - /usr/lib64/python2.6/site-packages/gtk-2.0 - /usr/lib/python2.6/site-packages - /usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg-info pythonversion: - 2 - 6 - 6 - final - 0 saltpath: /usr/lib/python2.6/site-packages/salt saltversion: 2015.5.10 saltversioninfo: - 2015 - 5 - 10 - 0 selinux: ---------- enabled: False enforced: Disabled serialnumber: VMware-56 4d c8 bc 18 86 5f 20-cb 2f 72 e2 bb f3 43 86 server_id: 175207945 shell: /bin/sh virtual: VMware zmqversion: 3.2.5
当然，也可以就某一个Grains项进行查询，如下所示：
[root@salt-master ~]# salt 'salt-minion01.contoso.com' grains.item ossalt-minion01.contoso.com: ---------- os: CentOS[root@salt-master ~]# salt 'salt-minion01.contoso.com' grains.item kernelreleasesalt-minion01.contoso.com: ---------- kernelrelease: 2.6.32-431.el6.x86_64[root@salt-master ~]# salt 'salt-minion01.contoso.com' grains.item hostsalt-minion01.contoso.com: ---------- host: salt-minion01
获取到上述Grains项之后，就可以有目的的进行匹配了，示例如下：
[root@salt-master ~]# salt -G 'os:CentOS' test.pingsalt-minion02.contoso.com: Truesalt-minion01.contoso.com: True[root@salt-master ~]# salt -G 'kernelrelease:2.6.32-431.el6.x86_64' test.pingsalt-minion02.contoso.com: Truesalt-minion01.contoso.com: True
4、组匹配
首先，编辑master的配置文件，并添加如下内容：
vim /etc/salt/master
nodegroups:
testgroup1: 'L@salt-minion01.contoso.com,salt-minion02.contoso.com'
testgroup2: 'G@os:CentOS and G@domain:contoso.com'
testgroup3: 'G@os:CentOS and E@salt-minion01.*'
然后就可以根据master配置中定义中的组进行匹配，示例如下：
[root@salt-master ~]# salt -N testgroup1 test.pingsalt-minion01.contoso.com: Truesalt-minion02.contoso.com: True[root@salt-master ~]# salt -N testgroup2 test.pingsalt-minion01.contoso.com: Truesalt-minion02.contoso.com: True[root@salt-master ~]# salt -N testgroup3 test.pingsalt-minion01.contoso.com: True
5、复合匹配
[root@salt-master ~]# salt -C 'G@os:CentOS and E@salt-minion02*' test.pingsalt-minion02.contoso.com: Truesalt-minion01.contoso.com: True[root@salt-master ~]# salt -C 'G@host:salt-minion01 or L@salt-minion02.contoso.com' test.pingsalt-minion01.contoso.com: Truesalt-minion02.contoso.com: True[root@salt-master ~]# salt -C 'G@host:salt-minion01 and G@domain:contoso.com' test.pingsalt-minion01.contoso.com: True
6、CIDR匹配
[root@salt-master ~]# salt -S '192.168.49.0/24' test.pingsalt-minion01.contoso.com: Truesalt-minion02.contoso.com: True[root@salt-master ~]# salt -S '192.168.49.101' test.pingsalt-minion01.contoso.com: True
7、Pillar匹配（暂时省却，后续添加）
