Saltstack Study Notes 7-states

States is a configuration language in Saltstack and requires a large number of states files to be written in daily configuration management. For example, install a package, then manage a configuration file, and finally ensure that a service runs correctly.

Write some states SLS files (files describing the state configuration) to describe and implement our functionality. The states SLS file is written in Yaml syntax. Of course states SLS files also support the use of the Python language, in fact, writing states SLS files is not difficult, the official provides a large number of examples, we just need to remember to write the format, and then according to their actual needs to write the appropriate states SLS file for their own business

----------------------------------------------------------------------------------

Let's use a simple example to understand states, and through examples we can see some of the processes and uses of States

Writing a Top.sls file (not required)

Writing States.sls files

In large-scale configuration management work, you need to write a large number of STATES.SLS files. Top.sls is the entry file for the states system, which is responsible for developing which devices call which States.sls files in a large-scale configuration management effort.

We maintain a set of LNMP architecture, we write a lot of States.sls files, it is necessary to deploy the entire LNMP environment in one click, it is necessary to States.sls Top.sls portal file to specify which STATES.SLS files are referenced by the Web machine and DB machine respectively.

Let's start with a new One.sls states file in states's working directory (the base environment defaults to/srv/salt)

Vim/srv/salt/one.sls

/tmp/foo.conf: #id

File.managed: Managed function of the #使用file states

-Source:salt://foo.conf #文件来源 (salt://represents states's working directory)

-User:root #文件属主

-Group:root #文件属组

-mode:644 #文件权限

-Backup:minion #备份原文件

This is a simple file management States.sls file, we can see the method described above file.managed more parameters, the function of this States.sls file is to achieve Minion/tmp/ foo.conf file for unified management, below we can create a new foo.conf file under the states working directory, and then configure the deployment for Minion:

echo "Saltstack Books" >/src/salt/foo.conf

Salt ' * ' State.sls one

Minion1:

----------

ID:/tmp/foo.conf

Function:file.managed

Result:true

Comment:file/tmp/foo.conf is in the correct state

started:14:43:01.568340

duration:12.401 ms

Changes:

Summary

------------

Succeeded:1

failed:0

------------

Total states Run:1

Minion2:

----------

ID:/tmp/foo.conf

Function:file.managed

Result:true

comment:file/tmp/foo.conf Updated

started:00:43:33.336318

duration:109.696 ms

Changes:

----------

Diff:

New file

Mode

0644

Summary

------------

Succeeded:1 (changed=1)

failed:0

------------

Total states Run:1

This completes the simple file management of the Minion machine. Let's introduce a simple configuration management for multiple machines using the TOP.SLS portal file

------------------------------------------------------------------------------------

Create a new Top.sls file in states's working directory first

Vim/srv/salt/top.sls

Base

‘*‘:

-One

' Minion1 ':

-Double

' Minion2 ':

-Three

Then we set up three states file One.sls,two.sls,three.sls, and finally we use the State.highstate command to synchronize simultaneously

Salt ' * ' state.highstate
