Saltstack Common Module Case analysis

Summary :Saltstack is a centralized server infrastructure management platform with configuration management, remote execution, monitoring and other functions, can generally be understood as a simplified version of the puppet and enhanced Func. Saltstack is based on the Python language implementation and is built with a lightweight Message Queuing (ZeroMQ) and Python third-party modules (PYZMQ, Pycrypto, Pyjinjia2, Python-msgpack, and Pyyaml, etc.).

By deploying the Saltstack environment, we can execute batch commands on thousands of servers, configure centralized management according to different business characteristics, distribute files, collect server data, operating system base and package management, etc., Saltstack is the operation and maintenance personnel to improve work efficiency, Standardize the business configuration and operation of the sharp weapon.

Module : Saltstack is powerful is to have a lot of modules, these modules greatly improve our efficiency, but also continue to develop new modules, here first to enumerate some of the basic applications of common modules, more modules and use of methods please refer to the official website: https:// docs.saltstack.com/en/latest/ref/modules/all/

Experimental Environment : (To save space, only the Minion end slave this machine to operate)

master:10.0.4.52 CentOS Release 6.5 (final) slave:10.0.4.53 CentOS release 6.5 (final)

Module One: CMD module (Implementation of remote command line invocation execution)

# salt  ' slave '  cmd.run  ' uptime '         # Linux commands can be called remotely slave:     11:47:36 up 14 days,  3:26,   0 users,  load average: 0.00, 0.00, 0.00# salt  ' slave '  cmd.run  ' Df -h ' slave:    filesystem                          Size  used avail use% mounted on    /dev/mapper/vg_ localhost-lv_root   18g  3.0g   14g  19% /     tmpfs                              940m   84k   940m   1% /dev/shm    /dev/sda1                          485M   39M   421m   9% /boot

Module two: Cron module (to implement the crontab operation of the controlled host)

Well, first write here, and then continue to update the basic usage of more modules later.
