Jump to navigation. System administrators are critical to the reliable and successful operation of an organization and its network operations center and data center.
A sysadmin must have expertise with the system's underlying platform i. Sysadmin tasks are not limited to server management, maintenance, and repair, but also any functions that support a smoothly running production environment with minimal or no complaints from customers and end users. Although sysadmins have a seemingly endless list of responsibilities, some are more critical than others. If you work in a sysadmin role or hope to one daymake sure you are ready to follow these best practices.
Documentation is how sysadmins keep records of assets, including hardware and software types, counts, and licenses. Should there be any issues in the production windows system administrator roles and responsibilities pdf download files, documentation helps identify the hardware, virtual machine, appliance, software, etc.
Maintain license counts and details for physical servers and virtual servers VMsincluding licenses for Windows, subscriptions for Linux Windows system administrator roles and responsibilities pdf download files, and windows system administrator roles and responsibilities pdf download files license limit of hypervisor host. Communicate with the backup team and provide them the data and client priorities for backup.
The recommended backup criteria for production servers is:. Operating system patches for known vulnerabilities must be implemented promptly. There are many types and levels of patches, including:, windows system administrator roles and responsibilities pdf download files. When a patch is released, check the bug or vulnerability details to see how it applies to your system e. Make sure to cross-verify applications' compatibility with patches or upgrades. Before going live with any application, check its compatibility with your hardware and operating system, and make sure to do load testing with the support of application team, windows system administrator roles and responsibilities pdf download files.
By configuring a syslog server in the environment to keep records of system and application logs, in the event of an intrusion or issue, the sysadmin can check previous and real-time logs to diagnose and resolve the problem.
Many sysadmin tasks such as server health checkups, resource utilization, backup triggers, transfer files and logs, etc. must be done at specific times. Therefore, the sysadmin must write scripts or use external tools and configure them as cron jobs to do the tasks automatically at the proper time. Install and configure live monitoring tools like Nagios, windows system administrator roles and responsibilities pdf download files, HP, etc. While these are the most important tasks a sysadmin is responsible for, there is much more to the role than the duties on this list.
The sysadmin is always a single point of content SPOC in the data center or network operations center for issues related to web hosting, application and server outages, and other critical IT operations problems. What other tasks or best practices do you think are essential for sysadmins? Please share your opinion in the comments. For example, "Maintain lists of your servers? Even a small shop has too many devices to manage by hand any more.
Besides, what about the need to maintain container images that are deployed to third party services? A far better recommendation would be, "Learn how to use auto-discovery tools and how to integrate them with your CMDB. Automation -- " write scripts or use external tools Learn to use tools like Ansible instead of doing any task by hand. Learn how to use version control systems like git to manage your playbooks, config files, windows system administrator roles and responsibilities pdf download files, scripts, etc.
The point I'm trying to make here is that the world of IT is changing incredibly rapidly. Agile and DevOps practices are penetrating into every organization. The practices that are outlined in this article simply don't align with that new world.
Sysadmins have to adapt if they are going to remain relevant. Thanks for the feedback. because generally there are L1, L2, L3 level of System admins with different level of responsibilities like documentation, monitoring, ticket handling, escalation handling etc.
And the System Admin on client locations must have to follow the instructions from the client with constraints and minimum tools and resources. Like, in many organizations the Patching is manual and in some patching may be automated. Autodiscovery tools are an option but inventory can be done simply by exporting the data from Virtual environment like VMware and same can be done for physical servers. Still there are multiple organizations, which are not using containeraized environment, Instead they are using private cloud only.
Integration, autodiscovery, what to use, how to use, when to use are only decided by customer and the System Admin must have to bind and follow the Instructions to make the things better with his best effort. So, the point is, that the article is general for 'To Dos' as a System Admin, it is not for specific or customized environment. How to do can only be decided by Service provider and Customer agreements by keeping the view of limitations of resources.
I both agree and disagree with you. However, to write an article such as this without mentioning what is happening to the industry and the transformative affect it is having on the job leaves the reader with at best an incomplete picture.
For example, I work for a fairly large U. based corporation approachingemployees. At that, we're very late to the game with many of our competitors and suppliers years ahead of us. In other words, I think that any article about sysadmin practices that doesn't discuss the impact of the truly transformative shift in the way that they will be doing their jobs in the very near future is doing the readers a disservice.
You are just concentrating on only 1 side of a coin. System Administration is not only Deveops. It is much more than Deveops.

Software inventory Configured applications: e. Third-party software: Any software not shipped with the installed OS License details Maintain license counts and details for physical servers and virtual servers VMsincluding licenses for Windows, subscriptions for Linux OS, and the license limit of hypervisor host. Server health checkup Running processes: Check for processes that are consuming more resources than expected, and take action to fine-tune the applications with the help of the application team.
CPU utilization: Consistently monitor and check the CPU utilization of the critical process like "java", "http", "mysql" etc. to ensure that these are not consuming the CPU resources more than expected. If it is so, then coordinate with the application team to check it at application level and fine tune the same.
Parallely analyse the OS parameters like "Ulimits". Memory utilization: Check memory utilization and clear the cache, if required. Zombie processes: Check for processes where the PID still exists in the process table after it is terminated. Zombie processes degrade server performance, so find and kill any that exist. Load average: If you're having performance windows system administrator roles and responsibilities pdf download files, check the load average and tune the server for performance.
If you find any issues, coordinate with the storage and network teams immediately to correct them. Backup and disaster recovery planning Communicate with the backup team and provide them the data and client priorities for backup. The recommended backup criteria for production servers is: Incremental backups: Daily, Monday to Friday Full backup: Saturday and Sunday Disaster recovery drills: Perform restoration mock drills once a month preferably, or quarterly if necessary with the backup team to ensure the data can be restored in case of an issue.
Patching Operating system patches for known vulnerabilities must be implemented promptly. There are many types and levels of patches, including: Security Critical Moderate When a patch is released, check the bug or vulnerability details to see how it applies to your system e.

Server hardening Linux: Set a BIOS password: This prevents users from altering BIOS settings. Set a GRUB password: This stops users from altering the GRUB bootloader. Deny root access: Rejecting root access minimizes the probability of intrusions. Sudo users: Make sudo users and assign limited privileges to invoke commands. TCP wrappers: This is the weapon to protect a server from hackers. Apply a rule for the SSH daemon to allow only trusted hosts to access the server, and deny all others.
Apply similar rules for other services like FTP, SSH File Transfer Protocol, etc. Include the particular port, source IP, windows system administrator roles and responsibilities pdf download files, and destination IP and allow, reject, deny ICMP requests, etc. for the public zone and private zone. Antivirus: Install antivirus software and update virus definitions regularly.
Secure and audit logs: Check the logs regularly and when required. Rotate the logs: Keep the logs for limited period of time like "for 7 days", to keep the sufficient disk space for flawless operation. Windows: Set a BIOS password: This prevents users from altering BIOS settings.
Configure firewall rules: Prevent unauthorized parties from accessing your systems. Deny administrator login: Limit users' ability to make changes that could increase your systems' vulnerabilities. Use a syslog server By configuring a syslog server in the environment to keep records of system and application logs, in the event of an intrusion or issue, the sysadmin can check previous and real-time logs to diagnose and resolve the problem.
