How to set the IP address in Linux:
File ifcfg-eth0 file path required to configure the network:/eth/sysconfig/network-scripts/ifcfg-eth0
ifcfg-eth0 file configuration analysis:
TYPE=Ethernet DEVICE=eth0 BOOTPROTO=none ONBOOT=yes IPADDR=192.168.16.12 NETMASK=255.255.255.0 GATEWAY=192.168.16.1 BROADCAST=192.168.16.255 HWADDR=00:0C:29:13:5D:74 PEERDNS=yes DNS1=10.0.1.41 USERCTL=no NM_CONTROLLED=no IPV6INIT=yes IPV6ADDR=FD55:fe80::28c2:e745:835f:c8d0/64
Attachment. Configuration parameter description
Note: These parameter values are not case-sensitive, do not distinguish between single quotes and double quotes, and may not even be used quotation marks.
TYPE: Configuration file interface type. There are various network configuration files in the /etc/sysconfig/network-scripts/ directory, including Ethernet, IPsec and other types. The network interface type is Ethernet.
DEVICE: Network interface name
BOOTPROTO: System startup address protocol
none: Do not use startup address protocol
bootp: BOOTP protocol
dhcp: DHCP dynamic address protocol
static: Static address protocol
ONBOOT: Whether to activate when the system starts
yes: Activate the network interface when the system starts
no: Do not activate this network interface when the system starts
IPADDR: IP address
NETMASK: Subnet mask
GATEWAY: Gateway address
BROADCAST: Broadcast address
Configuration takes effect
In order to make the network configuration permanently valid, the network interface configuration file under /etc/sysconfig/network-scripts/ was modified in Part 2. However, modifications to these files will not take effect immediately. There are two ways to make the network configuration of the modified file take effect:
1) Execute the service network restart command to restart the network service (recommended)
# service network restart
2) Restart the computer
# reboot

Linux: How to Enter Recovery Mode (and Maintenance)Apr 18, 2025 am 12:05 AMThe steps to enter Linux recovery mode are: 1. Restart the system and press the specific key to enter the GRUB menu; 2. Select the option with (recoverymode); 3. Select the operation in the recovery mode menu, such as fsck or root. Recovery mode allows you to start the system in single-user mode, perform file system checks and repairs, edit configuration files, and other operations to help solve system problems.
Linux's Essential Components: Explained for BeginnersApr 17, 2025 am 12:08 AMThe core components of Linux include the kernel, file system, shell and common tools. 1. The kernel manages hardware resources and provides basic services. 2. The file system organizes and stores data. 3. Shell is the interface for users to interact with the system. 4. Common tools help complete daily tasks.
Linux: A Look at Its Fundamental StructureApr 16, 2025 am 12:01 AMThe 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.
Linux Operations: System Administration and MaintenanceApr 15, 2025 am 12:10 AMThe 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.
Understanding Linux's Maintenance Mode: The EssentialsApr 14, 2025 am 12:04 AMLinux 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.
How Debian improves Hadoop data processing speedApr 13, 2025 am 11:54 AMThis 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
How to learn Debian syslogApr 13, 2025 am 11:51 AMThis guide will guide you to learn how to use Syslog in Debian systems. Syslog is a key service in Linux systems for logging system and application log messages. It helps administrators monitor and analyze system activity to quickly identify and resolve problems. 1. Basic knowledge of Syslog The core functions of Syslog include: centrally collecting and managing log messages; supporting multiple log output formats and target locations (such as files or networks); providing real-time log viewing and filtering functions. 2. Install and configure Syslog (using Rsyslog) The Debian system uses Rsyslog by default. You can install it with the following command: sudoaptupdatesud
How to choose Hadoop version in DebianApr 13, 2025 am 11:48 AMWhen choosing a Hadoop version suitable for Debian system, the following key factors need to be considered: 1. Stability and long-term support: For users who pursue stability and security, it is recommended to choose a Debian stable version, such as Debian11 (Bullseye). This version has been fully tested and has a support cycle of up to five years, which can ensure the stable operation of the system. 2. Package update speed: If you need to use the latest Hadoop features and features, you can consider Debian's unstable version (Sid). However, it should be noted that unstable versions may have compatibility issues and stability risks. 3. Community support and resources: Debian has huge community support, which can provide rich documentation and
