Can DataGuard be implemented in different versions of Linux?

It seems that you are going to do php**, then go to the next BSD, go to the main station.

These Linux "versions" are called distributions, some are free, some are paid, and most personal editions are free. Each Linux distribution has its own version number, and the latest versions of different distributions use the same kernel (except for domestic distributions), the difference is that the interface is different, and the driver libraries are different. Some of the larger distributions also include installation support (similar to Windows Installer for Windows), which also has different installation support.

At present, the three Linux distributions that are most suitable for ordinary users are called Ubuntu (the most convenient to use, if you are connected to the Internet, you can basically install what you want, no need to enter the command line), OpenSuse (the most beautiful interface, more convenient to use), and Fedora (Redhat Red Hat is produced by the same company, the system is the most stable, but it requires some academic foundation).

If you are using Linux for the first time, it is recommended that you install Ubuntu, otherwise it is likely that you will switch back to Windows in a few days.

Basically the same key is the kernel Red Hat is currently the best operating system with Linux as the kernel! Recommended use.

What about the red flag? Support the second floor.

There is no distro distinction between application software under Linux, the only difference is that the package management of different distros may be different, for example, the package management of Redhat or Fedora is rpm, and the software extension of these two distros is *rpm, Debian's package management is deb, and the software name is *deb,The same software is just a different extension,Of course, strictly speaking, linux files are not distinguished by extensions,For different distributions, the installation of the same software may be different,There is no compatibility problem after installation。

The core operating system is the same, the file type is the same, the structure is the same, and the application software is 99% the same.

Don't use software packages.

Just compile with the source**!

Not all of them are compatible, but most of them are.

It depends on the language in which the software is developed.

Common scripting languages can be used, such as Perl Python, etc.

But C or similar software that needs to be compiled is a software.

Not necessarily, and for hardware systems, there is a difference between 32-bit and 64-bit, so it is recommended to install and manage the software through RPM packages.

Not necessarily universal... Strictly speaking, there are very few software that can be used universally...

Some need to be recompiled.

This is also a big disadvantage of linux...

Yes, install it in a different partition on it. The grub menu is automatically generated.

No, right?,2 Linux common one root directory,One usr,How to use this?,Is it SUSE or AS3?

What's more, it's all linux, and they can do the same thing, so why spend this extra effort and hard disk space to install 2 linux.

OK. As long as you have enough hard disk space, you can generally use 20G for a system. A minimum of 10g is also required. Just free up the hard disk space separately.

Note manual partitioning. English has to be read.

User-friendly and aesthetically pleasing Ubuntu is preferred. Fedora is recommended though

Nowadays Linux distributions are mostly in 2 camps:

Ubuntu Debian wears a pair of pants.

Redhat Centos Fedora wears a pair of pants.

Ubuntu is a derivative of Debian. The interface is more user-friendly, which is easy for desktop users, and is not widely used in server applications.

If you are making a server, the first choice is Redhat CentOS, CentOS is a shadow version of Redhat, but RedHat updates use RHN to charge, and CentOS is free. Both contents are almost identical.

Redhat now doesn't make a desktop version of Linux itself, but works with the open source community to develop Fedora

Overall,The interface is the best looking and most friendly elected ubuntu,If you learn to use it yourself, it's still fedora.,After all, some settings and commands are not quite the same between the two series.。 With Fedora, you can also learn Redhat along the way

Generally speaking, there are more people who use Fedora, and that one is convenient to use. If something goes wrong, it's easy to find someone.

The SUSE Linux interface is nice, but it's not as easy to use as Fedora.

I've been using ubuntu all the time, and now I'm using it, and the interface looks good.

Linux should learn the command line, all distributions are generally gnome, kde desktop, and kfce, which are not very good.

The vast majority can. Because they're all based on gnu.
