How to achieve high-reliability Linux SysOps architecture design through SSH

Introduction:

In today's era of rapid technological development, the Linux operating system is A high-performance, high-reliability system that is widely used in various industries. As enterprises continue to increase their requirements for system reliability, it has become particularly important to design a highly reliable Linux SysOps architecture. This article will introduce how to implement high-reliability Linux SysOps architecture design through SSH and provide specific code examples.

1. What is SSH

SSH (Secure Shell) is a secure network protocol based on encryption technology. It is often used to establish secure remote login connections in unsecured networks. The SSH protocol protects data transmission security by encrypting communication and also provides an authentication mechanism for the remote machine.

2. Why choose SSH

SSH has the following key features, making it the best choice for designing a high-reliability Linux SysOps architecture:

1. Encryption Transmission: SSH uses public keys, asymmetric keys, and symmetric keys to protect the confidentiality and integrity of data transmission.
2. Authentication: SSH provides a variety of authentication methods, including password, public key and two-factor authentication, etc., ensuring the security of the remote machine.
3. Port tunnel: SSH can securely transmit data between different network nodes by creating a port tunnel, ensuring data reliability.
4. File transfer: SSH not only supports logging into remote machines, but also supports file transfer and management, which facilitates the work of SysOps.

3. Linux SysOps architecture design to achieve high reliability based on SSH

The following is a sample code for Linux SysOps architecture design to achieve high reliability based on SSH:

1. SSH connection script (connect.sh):

!/bin/bash

Define the remote host IP and port

remote_host="192.168 .1.100"
remote_port="22"

Define login username and password

username="admin"
password="123456"

Define connection timeout Time

timeout=10

Establish a connection using SSH

sshpass -p $password ssh -p $remote_port -o ConnectTimeout=$timeout $username@$remote_host

2. File transfer script (transfer.sh):

!/bin/bash

Define the remote host IP and port

remote_host=" 192.168.1.100"
remote_port="22"

Define login username and password

username="admin"
password="123456"

Define transport File path

local_file="/path/to/local/file.txt"
remote_file="/path/to/remote/file.txt"

Use SSH to transfer files

sshpass -p $password scp -P $remote_port $local_file $username@$remote_host:$remote_file

4. Summary

Achieve high-reliability Linux SysOps architecture through SSH Design can ensure the safety, reliability and stability of the system. This article introduces the basic concepts and features of SSH, and provides sample code for SSH-based connections and file transfers. In practical applications, it can be adjusted and expanded according to specific needs and environments to meet various SysOps needs. I hope this article will help readers understand and use SSH to achieve high-reliability Linux SysOps architecture design.
