Real-time management

cmd.run way

Excuting an order

sudo Salt '*' cmd . run 'uptime'

System Module

System self-built module reference salt documentation http://docs.saltstack.com/en/latest/ref/modules/all/index.html

such as viewing minion of disk usage, use disk module usage function

sudo Salt '*' Disk . usage

Use sys.doc module queries related to the use of salt module. sys.doc equivalent system of man, can query the salt module online doc

sudo Salt '*' sys . doc Disk

Custom Module

Custom modules directory / SRV / Salt / _modules / , custom module paths generally /srv/salt/_modules/custom.py . Examples:

```$ Cat / SRV / Salt / _modules / custom . PY def Test (): return 'i am Test'

Manual synchronization module to the minion

`sudo Salt '*' saltutil . sync_modules`

Execution module

`sudo Salt '*' custom . Test`

###Targetting
Matching simple way: Shell Style & Perl regular match

|mode |meaning
|--   |--|
|*      |Match all minion
|web1    |Match web1
|web *    |Match the beginning of the web's minion
|web?    |Match 4 character ID web beginning of minion
|web [1-5]    |Match web1 to web5
|web [1,3]    |Match web1 and web3
|web1- (prod or devel)    |Match web1-prod and web1-devel

A list of matching

sudo Salt - L 'web1, web2' Test . ping

Grains Match

sudo Salt - G 'virtual: physical'   Test . ping   # Match all physical machine 

sudo Salt - G 'virtual: PHY *'   Test . ping   #grains match mode can also be used Shell Style & Perl regular mode

Pillar Match

sudo Salt - I 'master: ipv6: False' Test . ping

SLS file matching

'Virtual: physical' : 
    - match : Grain

States

minion states for implementing state management, the official reference documentation http://docs.saltstack.com/ref/states/all/index.html States define the path / src / Salt file_roots (in / etc / salt / master of variable definition), states use YAML file format definition states the file suffix is sls (Salt State), sls document preparation needs attention: When you want to reserve a space, otherwise it will cause a parse error

Manual mode execution state to modify the admin account bashrc Case Prepare /src/salt/bashrc.sls , which reads as follows

/ Home / admin /. bashrc : 
  File . managed : 
      - Source : Salt : // Files / bashrc 
      - user : admin
       -  group : admin
       - mode :  644

Ready for distribution bash file, Salt: // Files / bashrc correspondence / srv / salt / files / bashrc make bash.sls take effect

sudo Salt '*' State . sls 'bashrc'

Highstate way. In fact, as the state is using top.sls entrance file /src/salt/top.sls following documents, top.sls reference bashrc.sls

Base : 
    '*' : 
        - bashrc

Manually perform highstate into force

sudo Salt '*' State . highstate

Let minion performed automatically using a schedule highstate

Defined /srv/pillar/top.sls

 Base : 
    '*' : 
        - Schedule

Defined /srv/pillar/schedule.sls (30 minutes)

Schedule : 
    highstate : 
        function : State . highstate
            minutes :  30

Pillar

Official documents http://docs.saltstack.com/topics/tutorials/pillar.html pillar data definition path / SRV / pillar , entrance file: /srv/pillar/top.sls View pillar information

sudo Salt '*' pillar . Data

Grains Official documents http://docs.saltstack.com/topics/targeting/grains.html View grains classification

sudo Salt '*' Grains . LS

See all the information grains

sudo Salt '*' Grains . items

View grains a message

sudo Salt '*' Grains . Item osrelease

Custom grains

grains custom directory / SRV / Salt / _grains / , custom path /srv/salt/_grains/grans_test.py , example:

def grans_test (): 
  Grains =  {} 
  Grains [ 'grans_test' ]  =  'this is a grans Test!' 
  return Grains
 if __name__ ==  '__main__' : 
  Print grans_test ()

Synchronization grains

sudo Salt '*' saltutil . sync_grains

Check machine grains information

sudo Salt '*' Grains . Item grans_test

Job management

Salt real-time management of tasks are performed as Job

View Job being executed

sudo Salt - Jobs run . Active

View Job list (including implementation over)

sudo Salt - Jobs run . list_jobs

Displays the Job Status

sudo Salt - Jobs run . lookup_jid 20140408112045976162

Minion state management

View minion of the state up or down

sudo Salt - run manage . status   # See all state 
sudo Salt - run manage . up         # Look up the 
sudo Salt - run manage . down   # just look down the

View minion version, the command will prompt what you need to upgrade the version minion

sudo Salt - run manage . versions
