When playing at home, or when building vps, the Linux distribution used is centos, and then you need to get in touch with Ubuntu and later debian. It feels that although it is the same Linux distribution, there are quite a few differences. The system will also be assigned in the release version. The Linux kernel is used, and the basic commands are almost the same.
DebianDebian in a broad sense refers to a cooperative organization and its works dedicated to the creation of a free operating system. Because many of the kernel branches of the Debian project are based on the Linux macro kernel, and most of the basic tools in the operating system created by Debian developers come from GNU projects, so "Debian" is often referred to as Debian GNU/Linux.
The unofficial kernel branch also has Debian GNU/Hurd (Hurd microkernel) that only supports x86, and only supports Dyson (OpenSolaris mixed kernel) of amd64. These unofficial branches have some serious problems, and there is no practicality. For example, the Hurd microkernel is technically immature, and Dyson's basic functions are still not perfect.
"Debian" is officially pronounced /ˈdɛ.bi.ən/, and Debian is an international collaborative project. The official does not specify any non-English name.
VMPlayer creates a virtual machine, the virtual disk can be set to about 4G (may need more if you use swap), all as the root partition, the file system uses
Btrfs (mkfs.btrfs -dsingle -l16384 -msingle -n16384 -K -f /dev/sda1) or
Zfs (zpool create -f -o ashift=12 -o cachefile= -O utf8only=on -O compression=lz4 -O dedup=off -O xattr=off -O secondarycache=none -O checksum=off -O atime=off -m /mountpoint zroot /dev/sda1, need to recompile the kernel and generate a new initialization file system)
Open debian-7.5.0-amd64-netinst.iso (no stable network using debian-7.5.0-amd64-DVD-1.iso) to enter the installation interface, follow the prompts to install.
CentOS (Community Enterprise Operating System, Chinese community operating system) is one of the Linux distributions compiled from source code released by Red Hat Enterprise Linux in accordance with open source specifications. Because of the same source code, some servers that require a high degree of stability use CentOS instead of the commercial version of Red Hat Enterprise Linux. The difference between the two is that CentOS does not include closed source software.
Characteristics
1. Think of CentOS as the Red Hat AS series! It was completely released after the improvement of Red Hat AS! There is no difference between various operations, use and RED HAT!
2. CentOS is completely free and there is no problem with the serial number required for RED HAT AS4.
3. CentOS's unique yum command supports online upgrades, allowing you to update your system instantly, unlike RED HAT, which requires you to pay for support!
4. CentOS fixes a lot of RHEL bugs!
5. CentOS Release Notes: CentOS3.1 is equivalent to RED HAT AS3 Update1 CentOS3.4 is equivalent to RED HAT AS3 Update4 CentOS4.0 is equivalent to RED HAT AS4
Linux was first written by Linus torvalds in 1991. Prior to this, Richard Stallman created the free software foundation (FSF) organization and the GNU project, and continued to write and create GNU programs. And with outstanding programmers and developers joining the GNU organization, it has created the Linux we see today, or GNU\Linux.
Linux distribution
Linux distributions fall into two broad categories, one is a distribution maintained by a commercial company, and the other is a distribution maintained by a community organization. The former is represented by the famous redhat (RHEL), and the latter is represented by debian.
Redhat seriesThe power of the redhat series is probably the following: RHEL (redhat enterprise linux), Fedora core, centos.
RHEL: It is a paid version issued by redhat company, which is very stable.
Fedora: It is the desktop version of redhat, the interface is elegant, the function and tool version are very high, but not very stable.
Centos: Redhat's community version, similar to RHEL, but free.
The redhat series of package management methods are: YUM package management based on RPM package.
The redhat series of package distribution methods are: compiled binary files.
The characteristics of the redhat faction are: more information, many online tutorials are based on centos.
Debian seriesDebian is a model for the development of community-based Linux. It is the most widely used Linux system to date. The series mainly includes: debian and Ubuntu.
Debian is divided into three branches: stable, testing, and unstable. Unstable has the latest packages, but there may be bugs that are generally suitable for desktop users. Testing is relatively more stable and supports many new technologies. Stable is very stable, but the package may be outdated.
Debian's most distinctive feature is the apt-get/dpkg package management method. In fact, redhat's YUM is also mimicking the debian apt method, but in the binary distribution method, apt should be the best.
Debian features: There are rich communities, there are questions you can go to ask.
Ubuntu: Ubuntu is a near-perfect Linux desktop system with all the advantages of debian and the advantages it has enhanced.
to sum upNow I feel that the commands that may be in the package management are different. Other commands are similar because they are all Linux kernels.
