Automation in System Administraton – are you a middle level unix admin? it is for you.

Ramdev

I have started unixadminschool.com ( aka gurkulindia.com) in 2009 as my own personal reference blog, and later sometime i have realized that my leanings might be helpful for other unixadmins if I manage my knowledge-base in more user friendly format. And the result is today's' unixadminschool.com. You can connect me at - https://www.linkedin.com/in/unixadminschool/

    I would classify the OS automation tasks into three categories
    1. That executes on individual servers. Example : mirroring and splitting of disks, error monitoring, vitals ( CPU, Disk, Network usage), user privilege checks. Dynamic resource allocations also come in this category.
    2. Centralized scripting: Operated from central servers. NIS/NIS+ pushes, cleanups, password changes to multiple servers ( non-NIS), Datacollection and compile, software and config ( like snmp and smtp ) pushes and adhoc reports ( do I have weblogic licenses on what servers !!!). These scripts have to well written for cross platform and cross version compatibility
    3. Interdependent servers: Servers in cluster ( OS, network or application level clustering ). Automation here requires knowledge of what is happening on one server to another. Jobs scheduled should here know not just at “what time”, but also “after success of X” or “on failure of Y”

    Hi bro… this is great idea…many of us are looking forward to learn scripting to make life easier and simple in this adminstration world. I am having hard time lately to learn r to find some training materials for perl scripting….it will wonderful if you can offer some paid classes too…

  18. ravi says:

    Awaiting from a long time……please start the practical scripting stuffs…..start with the basics and with pratical scenarios like…
    1) moving the application logs from local disk to a log server.(before moving the script should zip it and then move)
    2) script for userlogs(whenever a user logs in, a log should get created on some path which will contains all the activities done by user), the log name should consists of username_date/time_hostname.
    3) script for CPU and RAM usage for every 1 min and which will redirect the output to a file.
    4) script for sending mail to a particular user at a particular time………………etc
