About a .saltstack

1.saltstack profile:

Saltstack is a Python-based development of a C / S architecture, with Puppet, Ansible-in-one configuration management tool, it is very powerful, and reusability of each module incorporates high; the use of message queues ZeroMQ known as the fastest in the world Saltstack that can be performed on a second level of tens of thousands of servers of various operations, and RAS Key used to confirm the identity embodiment, transmission using AES encryption, higher safety performance;
Saltstack just a configuration management tools, or to make a cloud and data center infrastructure orchestration tool. Currently Salt-cloud projects have been incorporated into the main project in Saltstack, Saltstack has supported Docker related modules, after the friendly support of major cloud platform, with Saltstack of Mine achievement of the cloud platform services automatically extended.

2. Communication port:

• master end: 4505
• minion end: 4506

salt of master listens on port 4505 and 4506,4505 salt is used to publish information; 4506 is used to monitor salt client-side port to communicate with the service return data. minion end not listen port, after the minion start automatically registers connected to the master through, stays connected after the adoption.

3. Main features:

• A configuration management system, capable of maintaining a predefined remote node status (for example, to ensure that the specified report to be installed, the specified service running)
• Remote execution of a distributed system for the remote node (which may be a single node, the rules may be any chosen node) query data and execute commands on

II. Experiments

1. Deploy experimental environment

server1:

yum install salt-master -y		##这里已经配好了yum源（包含所有依赖关系）

server2:

yum insall -y salt-minion

server3:

yum install -y salt-minion

2. Open the salt-master

[root@server1 salt]# systemctl start salt-master
[root@server1 salt]# netstat -antlp

3. Configure server2, server3 the salt-minion

[root@server2 ~]# cd /etc/salt/
[root@server2 salt]# ls
cloud           cloud.maps.d       master    minion.d  proxy.d
cloud.conf.d    cloud.profiles.d   master.d  pki       roster
cloud.deploy.d  cloud.providers.d  minion    proxy
[root@server2 salt]# vim minion
16 master: 172.25.31.1

[root@server2 salt]# systemctl start  salt-minion

The same operation server3

3. server2, server3 added

[root@server1 salt]# salt-key -L	  	##-L列出所有
[root@server1 salt]# salt-key -A		##加入

4. Check the port-specific information

[root@server1 salt]# yum install -y lsof
[root@server1 salt]# lsof -i :4505

[root@server1 salt]# vim master
[root@server1 salt]# systemctl restart salt-master

Two .saltstack applications

1. Installation server2 httpd

[root@server1 apache]# pwd
/srv/salt/apache
[root@server1 apache]# ls
apache.sls  files  install.sls
[root@server1 apache]# cat install.sls

      - httpd

  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://apache/files/httpd.conf

  service.running:

    - reload: True
    - watch:
      - file: install-apache
[root@server1 apache]# cd files/
[root@server1 files]# ls
