Is ubuntu a linux operating system?
linux is the name of the kernel, and ubuntu is a distribution based on the linux kernel.
We often talk about the Linux operating system and Ubuntu operating system. This term is incorrect. Strictly speaking, Linux is not an operating system, but a kernel that belongs to the operating system.
Since Linux is open source and free, programmers can change it according to their own interests and inspirations and combine it into the operating system they want;
Using Linux as the kernel There are many operating systems. We call this operating system a Linux distribution, or simply use Linux to collectively refer to operating systems with Linux as the kernel.
Ubuntu is a distribution of Linux system. A Debian-based distribution, operating system using the gnome desktop environment. It is basically equivalent to the relationship between win8 and windows, except that win is produced by Microsoft.
Linux is a free-to-use and freely disseminated Unix-like operating system. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and UNIX.
Strictly speaking, the word Linux itself only refers to the Linux kernel, but in fact people are accustomed to using Linux to describe the entire operating system based on the Linux kernel and using various tools and databases of the GNU Project.
For Ubuntu, it is the concrete version of the Linux operating system, and for Ubuntu, Linux is its abstraction; in the Linux operating system, due to different applications and management strategies, there are multiple versions, such as : ubuntu, fedora, redhat, centos, etc.;
Ubuntu (Ubuntu) is a Linux operating system mainly based on desktop applications and belongs to the Linux operating system.
Ubuntu is based on Debian GNU/Linux, supports x86, amd64 (x64) and ppc architecture, and is an open source GNU/Linux operating system created by a global professional development team (Canonical Ltd). Provides a support platform for desktop virtualization. Ubuntu has made a huge contribution to the popularization of GNU/Linux, especially the desktop, allowing more people to share the achievements and excitement of open source.
Ubuntu provides a robust, feature-rich computing environment suitable for both home use and business environments. The Ubuntu community is committed to releasing a new version every 6 months to provide the latest and most powerful software.
The word Ubuntu is regarded as a traditional African national concept, and is also considered one of the founding principles of the Republic of South Africa, and is closely related to the ideal of African renaissance. The word originates from Zulu and Xhosa. Its core concept is "treating people with humanity" and focuses on mutual loyalty and communication between people. South African President Nelson Mandela explained this: Ubuntu is a concept that contains many connotations of respect, mutual help, sharing, communication, care, trust, and selflessness: Ubuntu is a way of life that advocates tolerance and compassion for others. It can be seen that the Ubuntu spirit has penetrated into South Africa's politics and daily life.
The spirit of Ubuntu coincides with the spirit of open source software. As an operating system based on Linux, Ubuntu attempts to extend this spirit to the computer world, "Software should be shared and available to anyone who needs it." Ubuntu's goal is to allow everyone in the world to get one Easy-to-use Linux version regardless of one's geographical location and physical condition.
Under the guidance of this Ubuntu spirit, Ubuntu Linux promises as follows:
Ubuntu is free for personal use, organization and internal development use of enterprises, but There is no after-sales support for this use.
Ubuntu will provide commercial support to hundreds of companies around the world.
Ubuntu contains the best translations and localizations provided by the free software community.
The Ubuntu CD contains only free software, and users are encouraged to use free and open source software, and to improve and spread it.
Expand knowledge:
It is usually said that Linux is similar to Unix, but there is a big difference between the two
Unix Manufacturers basically jointly develop software and hardware, so Unix systems are not very versatile. They are mainly designed specifically for specialized hardware, so the performance and stability are extremely good; and Linux is indeed It is a general system, and most manufacturers do not produce their own hardware (only a few manufacturers like redhat
do so, so they make a lot of money), so the biggest advantage of Linux is good compatibility, but this This determines that the performance cannot be maximized...
From a commercial perspective, due to the above performance differences, two different business models have resulted. Unix software and hardware are sold together, and they are very expensive (except for freebsd ),
Linux only sells software, most of which are free (manufacturers like Radhat who take the Unix path are still in the minority); therefore, Unix is suitable for large enterprises, while Linux is suitable for small and medium-sized enterprises and individuals
These operating systems are used The basic kernel of linux is the same. The difference is that they have made certain modifications to this kernel. Users will have a little difference when using it. But as long as you understand one of the linux operating systems, other versions can also be used. It’s almost done

The basic structure of Linux includes the kernel, file system, and shell. 1) Kernel management hardware resources and use uname-r to view the version. 2) The EXT4 file system supports large files and logs and is created using mkfs.ext4. 3) Shell provides command line interaction such as Bash, and lists files using ls-l.

The key steps in Linux system management and maintenance include: 1) Master the basic knowledge, such as file system structure and user management; 2) Carry out system monitoring and resource management, use top, htop and other tools; 3) Use system logs to troubleshoot, use journalctl and other tools; 4) Write automated scripts and task scheduling, use cron tools; 5) implement security management and protection, configure firewalls through iptables; 6) Carry out performance optimization and best practices, adjust kernel parameters and develop good habits.

Linux maintenance mode is entered by adding init=/bin/bash or single parameters at startup. 1. Enter maintenance mode: Edit the GRUB menu and add startup parameters. 2. Remount the file system to read and write mode: mount-oremount,rw/. 3. Repair the file system: Use the fsck command, such as fsck/dev/sda1. 4. Back up the data and operate with caution to avoid data loss.

This article discusses how to improve Hadoop data processing efficiency on Debian systems. Optimization strategies cover hardware upgrades, operating system parameter adjustments, Hadoop configuration modifications, and the use of efficient algorithms and tools. 1. Hardware resource strengthening ensures that all nodes have consistent hardware configurations, especially paying attention to CPU, memory and network equipment performance. Choosing high-performance hardware components is essential to improve overall processing speed. 2. Operating system tunes file descriptors and network connections: Modify the /etc/security/limits.conf file to increase the upper limit of file descriptors and network connections allowed to be opened at the same time by the system. JVM parameter adjustment: Adjust in hadoop-env.sh file
