Old Machine Installs CentOS

512M memory, 80G HDD

Ubuntu-server no pressure, but because many platforms only support the CentOS server Linux system

The memory must be more than 1G by default to be installed with the graphical interface.
After the installation, even 256M of memory can run up.
Linux requirements for hardware itself is not very high, you learn the words of an old PC is enough for you to install and learn.
If you really want to set up a server, then you should follow the current configuration of the main server.

。 Do the server, basically from the minimization of the installation began, what to reload what. Minimizing the hassle of installation in the source code to install the software, you need to solve the dependent library problem.

Run 5.5 is more fluent, 6 did not try.

If the memory is too much surplus, do a memcache, but also to reduce the database pressure.

Now CentOS installs the GNOME and KDE desktop environments by default.
These two are the largest and most resources in the desktop environment,

It is recommended that LZ try the release version of the following xface or LXDE desktop environment
Do not manipulate graphics, just ssh up

64-bit vs. 32 difference

First, the CPU needs the CPU to support 64-bit
If your CPU is more than two cores, it certainly supports 64-bit operating systems. Use Cpu-z to check if your CPU contains EM64T (INTEL) or x86_64 (AMD) instructions! If included, that means 64-bit support
The CPU is responsible for computing and processing, and the memory is exchanging data.
