Run Unix

your system has been using unix for a long timeIn an environment where the operating system is extremely stable and the host hardware operates properlyUNIX systems can operate smoothly and continuously
------------
I'm glad you can come to my websiteThe purpose of my website is very simple and clearI hope that the host/server of every UNIX system can continue to operate smoothlyBut it's not an easy goal

Not easy to achieve does not mean that UNIX is not stable enough
It is the relationship of the entire operating environment. . . .
Inside the system
UNIX operates on the hardware, the system is operating, the relative hardware equipment will have the problem of use loss and use time limit.
Potential crises such as hard disk storage media / such issues usually result in online service interruptions system downtime
Maybe you will think that this is not a problem (it doesn't take much time to restart the system, but the actual situation is that the hard disk is damaged and the system cannot be turned on)
All standard system operations generate many system logs that take up space on your system
When the partition / /var /tmp that keeps the system functioning well runs out of space
The system will start abnormal because there is not enough space to store the temporary files generated during the operation of the system.
This can also cause disruption to online services
A proper system usually does not reboot or shut down once online service is started
But the core components at the hardware level/card (adapter) disk ram also have a service life
They don't need to be corrupted, they just need to be anomalies that cause the data calculated by the system to be wrong
This will expand the problem
Now is the era of big data
Many systems in the manufacturing production line are also responsible for the important use of data preservation.
Once the system is out of service, the accompanying production line also needs to stop production and wait for the system to recover

Transactions are built on trust
What can I do for you with my knowledge of UNIX
benefit you and me
I can remotely access your system host through a secure connection
what does it do for you?
Usually I need to check your environment first
In this regard, what is your hardware architecture, what subsystems are there outside the main system (such as external storage devices)
What is the make and model number of your hardware (if this is a very old device I can remind you if the parts are lacking in the event of a disaster)
Then there is the application software on the system. In addition to the old website application software, the host has high security doubts.
It will also make the application of new web technologies infeasible.
The above system information is what the system maintainer needs to master, just like a family doctor, so you need to trust me like a doctor
Let me get information about the operation of the system
Software Name Software Version Hardware Information Network Information
If you can provide me with architectural information, I can control your system environment more efficiently, which is good for you
But I will still conduct an overall system check. If the information you provide is wrong, you can also take this opportunity to correct it.
