Summarize the differences between centos and ubuntu commands
The following tutorial column will introduce and summarize the differences between centos and ubuntu commands. I hope it will be helpful to friends in need!
CentOS (Community ENTerprise Operating System) is one of the Linux distributions. It is compiled from the source code released by Red Hat Enterprise Linux in accordance with the open source code regulations. become. Because it comes from the same source code, some servers that require high stability use CentOS instead of the commercial version of Red Hat Enterprise Linux.Ubuntu is a Linux operating system mainly based on desktop applications. Ubuntu is based on the Debian distribution and the GNOME desktop environment. The difference from Debian is that it releases a new version every 6 months. The goal of Ubuntu is to provide general users with an up-to-date, yet fairly stable operating system mainly built from free software. Ubuntu has a huge community power, and users can easily get help from the community.
Both are service-level operating systems commonly used by individuals and small teams in the current version. Many open source software and libraries can be easily installed in the software library provided online. Both use bash as the basic shell, so in many basic commands, the difference between ubuntu and centos is not very obvious, and ubuntu does a better job in the desktop interface. It is the first choice for many people to learn Linux out of interest. Usually it is Ubuntu, after all, many people are still accustomed to operating under desktop graphics.
There are still many differences in usage habits and commands between Centos and Ubuntu. Here is a brief list:
1. The newly created non-root user in centos does not have sudo permissions. If you need to use sudo permissions, Accounts and permissions must be added to /etc/sudoers, so when switching to the root account, you only need to enter: su and add the password of the root account.In Ubuntu, the sudo command is generally used. If it is used for the first time, you will be prompted to enter the current user's password (instead of the root password)
2. In online installation software, centos uses the yum command, and The apt-get command is used in ubuntu. In addition, there is a method in yum to search for a software from the software source: yum search. The software name3.centos comes from redhat, so centos supports installation in rpm format, but ubuntu obviously does not support it.
4. After all, different companies make different distributions. The locations of many configuration files and the default file paths are very different. This needs to be gradually realized during use.
The command differences are summarized in the following table:

Improve HDFS performance on CentOS: A comprehensive optimization guide to optimize HDFS (Hadoop distributed file system) on CentOS requires comprehensive consideration of hardware, system configuration and network settings. This article provides a series of optimization strategies to help you improve HDFS performance. 1. Hardware upgrade and selection resource expansion: Increase the CPU, memory and storage capacity of the server as much as possible. High-performance hardware: adopts high-performance network cards and switches to improve network throughput. 2. System configuration fine-tuning kernel parameter adjustment: Modify /etc/sysctl.conf file to optimize kernel parameters such as TCP connection number, file handle number and memory management. For example, adjust TCP connection status and buffer size

The CentOS shutdown command is shutdown, and the syntax is shutdown [Options] Time [Information]. Options include: -h Stop the system immediately; -P Turn off the power after shutdown; -r restart; -t Waiting time.

The key differences between CentOS and Ubuntu are: origin (CentOS originates from Red Hat, for enterprises; Ubuntu originates from Debian, for individuals), package management (CentOS uses yum, focusing on stability; Ubuntu uses apt, for high update frequency), support cycle (CentOS provides 10 years of support, Ubuntu provides 5 years of LTS support), community support (CentOS focuses on stability, Ubuntu provides a wide range of tutorials and documents), uses (CentOS is biased towards servers, Ubuntu is suitable for servers and desktops), other differences include installation simplicity (CentOS is thin)

CentOS installation steps: Download the ISO image and burn bootable media; boot and select the installation source; select the language and keyboard layout; configure the network; partition the hard disk; set the system clock; create the root user; select the software package; start the installation; restart and boot from the hard disk after the installation is completed.

CentOS Platform Hadoop Distributed File System (HDFS) Performance Optimization Guide Optimizing HDFS Performance is a multi-faceted issue, and multiple parameters need to be adjusted for specific situations. The following are some key optimization strategies: 1. Memory management adjusts the NameNode and DataNode memory configuration: reasonably configure the HADOOP_NAMENODE_OPTS and HADOOP_DATANODE_OPTS environment variables according to the actual memory size of the server to optimize memory utilization. Enable large page memory: For high memory consumption applications (such as HDFS), enabling large page memory can reduce memory page allocation and management overhead and improve efficiency. 2. Disk I/O optimization uses high-speed storage

Backup and Recovery Policy of GitLab under CentOS System In order to ensure data security and recoverability, GitLab on CentOS provides a variety of backup methods. This article will introduce several common backup methods, configuration parameters and recovery processes in detail to help you establish a complete GitLab backup and recovery strategy. 1.
