Servers are great inventions; They buzz along 24/7, generally without a problem, but they need some upkeep as well, like any other computer.
Simple monitoring and maintenance practices can also prevent a server from running into a catastrophe. For instance, some people called in distress that their server had crashed, so the investigation began, and it came out that their RAID collapsed last year, backups stopped two months ago, and disc hit 100 percent capacity, thus corrupting the database.
If you manage a server on your own, there are a few things that should be part of your server maintenance checklist to keep the optimal health system.
Confirm your backups are functional.
Before you make any adjustments to your production system, make sure your backups are running fine. You might also want to conduct some retrieval tests if you are deleting vital info. Apart from the above, you might also want to make sure that you have chosen the right location for keeping the backup data.
Review disk usage.
Refrain from using the production system as an archive. Delete old logs, e-mails, and software versions that are no longer used. Holding the device clean of old applications prevents security issues. Minor data footprint ensures a quicker recovery. If your use reaches 90% of the disc space, either minimize usage or add more storage. If your partition exceeds 100%, your server may stop reacting, database tables may get corrupted, and data might get lost.
Monitor RAID alarms.
Redundant Array of Independent/Inexpensive Disks (RAID) is a technology that enables data storage across multiple hard drives. Its aim is to achieve data redundancy in order to minimise data loss and to boost efficiency.
The RAID controller will beep under two conditions:
- Drive failure
- Reconstruction of the array
RAID should be used for all production servers. More significantly, you need to track your RAID status.
Update your Control Panel.
If you are utilizing a hosting or server control panel, be sure to update it as well. Often this involves upgrading, not just the control panel but also the applications that it controls. For instance, with WHM/cPanel, you need to update PHP versions to address known problems manually. Merely upgrading the panel does not upgrade Apache’s underlying versions and PHP used by your OS.
Keep a tab on application updates
Web applications account for more than 95% of all security violations investigated. Be sure to update your web applications, particularly popular WordPress programs.
Check for hardware errors
You may want to check the logs for any signs of hardware issues. Overheating warnings, disc interpret errors, network failures may be early symptoms of possible equipment failure. These are uncommon but worth looking at, particularly if the system has not been working within normal parameters.
We recommend changing passwords every six-twelve months, especially if you have revealed them to others for maintenance purposes. Skipping a simple exercise of password change may cost you extremely dear in case of security breach or hacking attacks, resulting in immense losses.
Review system security
Systematic analysis of your server’s security is recommended for making use of remote auditing tools. Frequent security audits act as a check on system configuration, OS updates and other possible security threats. Security experts propose this at least four times a year.
