Salt combined with crontab Auto-sync configuration file

Saltstack automatic synchronization configuration file, in fact, I am a combination of crontab to get, is to put the Minion end of the machine into a group, and then for this group to do job execution State.sls to do.

Note: In fact saltstack have their own schedule planning tasks. Just look at the dazed, and I bright actually job, and again, if you use automatic synchronization configuration file, if you have already know, and have been tested in the test environment, responsible for you know ... and auto-sync, you don't see the state of execution at all. So you know. In fact, these are and egg east.

One: To group the Minion, in order not to confuse with Master Master profile, create a separate configuration file, in the master configuration file, open the corresponding comments as follows

[Email protected]:~# grep "^default"/etc/salt/master

Default_include:master.d/*.conf

The Web in the configuration file is a group set for minion. Group name is web

[Email protected]:/etc/salt/master.d# cat nodegroup.conf

Nodegroups:

Web: ' [email protected] '

Test with a terminal command

[Email protected]:/etc/salt/master.d# salt-n Web test.ping

Iz23f6c5z8tz:

True

Two: Use salt to install Nginx, in the default base environment to create the APT directory, because I use apt to install Nginx, easy to test ....

[Email protected]:/srv/salt/base# Tree apt/

apt/

├──files

│└──nginx.conf

└──install.sls

1 directory, 2 files

The contents of the installed Nginx SLS file are as follows:

[Email protected]:/srv/salt/base/apt# cat Install.sls

Apt-nginx-install:

Cmd.run:

-Name:apt-get Install Nginx-y

-Unless:test-d/etc/nginx

Apt-nginx-config:

File.managed:

-Name:/etc/nginx/nginx.conf

-Source:salt://apt/files/nginx.conf

-User:root

-Group:root

-mode:644

Apt-nginx-service:

Service.running:

-Name:nginx

-Reload:true

-Require:

-Cmd:apt-nginx-install

-File:apt-nginx-config

-Watch:

-File:apt-nginx-config

Three: Installation Nginx

[Email protected]:/srv/salt/base/apt# salt-n web State.sls apt.install

Iz23f6c5z8tz:

----------

State:-cmd

Name:apt-get Install Nginx-y

Function:run

Result:true

Comment:unless Execution succeeded

Changes:

----------

Comment:file/etc/nginx/nginx.conf is in the correct state

Changes:

----------

View the minion-side Nginx service status for a Web group

[Email protected]:/srv/salt/base/apt/files# salt-n web cmd.run ' service nginx status '

Iz23f6c5z8tz:

* Nginx is running

Four: Set up scheduled Tasks, as well as modify Nginx configuration file, to see if the Nginx configuration file changes and load services, easy to test my setup every 1 minutes to execute,

#web Group Test Salt

*/1 * * * * salt-n web State.sls apt.install

Modify the nginx.conf configuration and stop the Nginx service to see if the configuration is changed and the service is overloaded

[Email protected]:/srv/salt/base/apt/files# salt-n web service.stop nginx

Iz23f6c5z8tz:

True

[Email protected]:/srv/salt/base/apt/files# salt-n web cmd.run ' service nginx status '

Iz23f6c5z8tz:

* Nginx is not running
