This article mainly shares with you the method of copying files between different Linux hosts. Copying files on the current host disk is very simple. Everyone is familiar with the cp command. I hope it can help you.
Usage:

cp [options] source dest
cp [options] source... directory

Function description: Copy one file to another file, or copy several files to another directory.
options parameter description:
-a Copy the file status, permissions and other information as they are as much as possible.
-r If source contains subdirectories, copy recursively to the destination.
-f means force, forced execution. If a file with the same file name already exists at the destination, the file will be overwritten (delete it before copying it and then copy it).

Example:
(1) Copy the file aaa (already exists) and name it bbb:

cp aaa bbb

(2) Copy all PHP language files to project In the subdirectory:

cp *.php project

So if you want to copy files between different Linux hosts, there are two common methods:

(1) Use FTP, that is, install ftp Server on one Linux, so that another client program using ftp can copy files.
(2) Use the scp command. scp is a file copy with Security, based on ssh login. This method is more convenient to operate. In order to transfer faster, it is best to compress the file before operation.
A. To copy the current file to another remote host, you can use the following command:

scp /home/wwwroot/shop.tar.gz root@192.168.230.128:/home/root

Then you will be prompted to enter the login password of the root user of the other 192.168.230.128 host. , and then the copying begins.
B. To copy files from the remote host to the current system, you can use the following command:

scp root@/shop.tar.gz 192.168.230.128:/home/root/shop.tar.gz home/wwwroot/shop.tar.gz

Linux Maintenance Mode: Understanding the PurposeApr 28, 2025 am 12:01 AM

Maintenance mode is used for system maintenance and repair, allowing administrators to work in a simplified environment. 1. System Repair: Repair corrupt file system and boot loader. 2. Password reset: reset the root user password. 3. Package management: Install, update or delete software packages. By modifying the GRUB configuration or entering maintenance mode with specific keys, you can safely exit after performing maintenance tasks.

Linux network configuration can be completed through the following steps: 1. Configure the network interface, use the ip command to temporarily set or edit the configuration file persistence settings. 2. Set up a static IP, suitable for devices that require a fixed IP. 3. Manage the firewall and use the iptables or firewalld tools to control network traffic.

Maintenance mode plays a key role in Linux system management, helping to repair, upgrade and configuration changes. 1. Enter maintenance mode. You can select it through the GRUB menu or use the command "sudosystemctlisolaterscue.target". 2. In maintenance mode, you can perform file system repair and system update operations. 3. Advanced usage includes tasks such as resetting the root password. 4. Common errors such as not being able to enter maintenance mode or mount the file system, can be fixed by checking the GRUB configuration and using the fsck command.

Linux: A Deep Dive into Its Fundamental PartsApr 21, 2025 am 12:03 AM

The core components of Linux include kernel, file system, shell, user and kernel space, device drivers, and performance optimization and best practices. 1) The kernel is the core of the system, managing hardware, memory and processes. 2) The file system organizes data and supports multiple types such as ext4, Btrfs and XFS. 3) Shell is the command center for users to interact with the system and supports scripting. 4) Separate user space from kernel space to ensure system stability. 5) The device driver connects the hardware to the operating system. 6) Performance optimization includes tuning system configuration and following best practices.
