Install And Use SALTStack In A Mixed Environment - Page 2
Testing the installed SaltStack
PING all running minions from Salt Master:
root@salt-master:~# salt '*' test.ping
You can use regexp in its name:
root@salt-master:~# salt 'salt-[m]*' test.ping
The result should be something like this:
salt-minion1.test.local:
True
salt-minion2.test.local:
True
root@salt-master:~# salt 'salt-[!m]*' test.ping
The result should be something like this:
salt-centos:
True
Single usage of SaltStack
The following examples manage Salt-Minions from Salt-Master

salt '*' service.get_all
salt '*' service.status nginx
salt '*' service.reload ssh
salt '*' service.disable rsync
salt '*' service.get_disabled
You will receive Fails if service is not installed.
Package installation to Minions from Master:
We can install packages by one single command on various distributions at the same time by:
root@salt-master:/srv/salt# salt '*' pkg.install subversion

Install MYSQL on Debian minions
It is a bit complicated than a single package

If you try out this command on all of your servers, you can see, something went wrong with CentOS.
You can see details in /var/log/salt/minion. If it not tell you enough, raise loglevel in /etc/salt/minion.
I will not go into the details, but not difficult to solve this.
If you want to manage mysql by SaltStack, you should have a file mysql_salt.conf.
As it was mentioned previously, you can manage this remotely too:
root@salt-master:~# salt 'salt-mini*' file.append /etc/salt/minion.d/mysql_salt.conf \ "mysql.host: 'localhost'" \ "mysql.port: 3306" \ "mysql.user: 'root'" \ "mysql.pass: ''" \ "mysql.db: 'mysql'"
salt-minion2.test.local:
Wrote 5 lines to "/etc/salt/minion.d/mysql_salt.conf"
salt-minion1.test.local:
Wrote 5 lines to "/etc/salt/minion.d/mysql_salt.conf"
At this point Salt-Minion restart needed.
The salt can not restart itself as "salt 'salt-mini*' service.restart salt-minion", so you have to use a trick:
root@salt-master:~# salt 'salt-mini*' cmd.run "/etc/init.d/salt-minion restart"
salt-minion2.test.local:
Restarting salt minion control daemon: salt-minion.
salt-minion1.test.local:
Restarting salt minion control daemon: salt-minion.

MySQL management on Minions from Salt-master
By now, you can use SaltStack DB managment commands on your Debian machines:
root@salt-master:~# salt 'salt-mini*' mysql.db_create 'dbname'
salt-minion2.test.local:
True
salt-minion1.test.local:
True
root@salt-master:~# salt 'salt-mini*' mysql.db_list
salt-minion2.test.local:
- information_schema
- dbname
- mysql
- performance_schema
- test
salt-minion1.test.local:
- information_schema
- dbname
- mysql
- performance_schema
- test
