When many beginners install Linux system, they question their computer configuration and worry whether they can meet the requirements of installing Linux. This section from the CPU, memory, hard disk, graphics card and other aspects, details about the installation of Linux system minimum configuration.
Based on the rapid development of hardware and the increase of core functions of the operating system, it is bound to eliminate a number of old computers, which have no ability to load the new operating system. For the most intuitive example, the hardware configuration before pentium-iii may no longer be able to carry today’s Linux distribution, and this part of computers may have unexplained downtime during operation due to aging electronic parts and other factors.
However, the hardware configuration required by the Linux system does not need to be too high-end. Generally speaking, computers with a production period of less than five years can basically meet the daily use of beginners. The most basic hardware configuration only needs to meet the following standards:
CPU: the CPU of Intel I3 and above system can fully support the normal operation of the system;
Memory: of course, the bigger the better. In fact, in Linux servers, memory is much more important than CPU, because if memory is not big enough, you have to use the memory in the hard disk to replace the space (also known as swap) But we all know that the efficiency of CPU reading data from memory is much higher than that from hard disk, so too small memory may affect the overall performance of the system. In general, for a small Linux server, it is recommended to have at least 512MB of memory.
The swap swap space is described in detail in the following chapters.
Hard disk: considering the different data volume and data access frequency, the requirements for hardware are also different. For example, if it is a general small server, its hard disk capacity is more than 20GB, which is basically enough. But if your server is used as a backup or as a file server for a small enterprise, then you may have to consider choosing an appropriate disk array (RAID) mode.
Simply understand, disk array (RAID) is a way to integrate multiple hard disks into a large hard disk by using hardware technology, and the final large hard disk will be seen in the system. More details about raid will be explained in the following chapters.
Graphics card: if the Linux system you install does not need x Windows desktop environment, then the graphics card is not so important; on the contrary, your graphics card should have more than 32MB of memory, otherwise the efficiency of running desktop environment will be very low.
Network card: it is one of the most important components of Linux server. At present, most motherboards have built-in 10 / 100 / 1000Mbps ultra high speed Ethernet card. It should be noted that there are some differences in the functions of different network cards. A better network card usually has a better linux driver and can be used more smoothly. Generally speaking, if your server needs frequent network read / write (I / O) function, try to choose the network card of Intel (Internet), Broadcom (Broadcom) and other large companies.
CD, keyboard and mouse: these hardware are non essential, can use on the line.
In addition, in addition to table 1, all developers who publish Linux distributions will give a detailed description of the hardware configuration they can support by default when they launch this version, so they can also go to the websites of relevant Linux distributions.
Based on the above, we can come to the conclusion that for beginners, 99% of the computers on the market can meet the needs of everyone to learn Linux, so readers can be assured to install Linux system on their computers.
