Installing a virtual machine on a CentOS system requires: Install virtualization software (such as KVM, VirtualBox or VMware ESXi) Create a virtual machine, allocate resources and install a virtual hard disk Install a guest operating system Configure virtual machine settings (such as shared files folders, snapshots, and security) to manage virtual machines (start, stop, clone, and update)
How to install a virtual machine on CentOS
Preface
A virtual machine is a virtual computing environment created on a physical host that allows you to run multiple operating systems on a single physical server. This article will guide you step by step on how to install a virtual machine on a CentOS system.
Step 1: Install virtualization software
First, you need to install virtualization software on your CentOS system. There are several popular virtualization software options available, including:
- KVM (Kernel-based Virtual Machine)
- VirtualBox
- VMware ESXi
Step 2: Create a virtual machine
After installing the virtualization software, you can start creating a virtual machine. The specific steps vary depending on the virtualization software selected, but the general steps are as follows:
- Allocate virtual machine resources (such as CPU, memory, storage)
- Create a virtual hard disk
- Install operating system
- Configure network connection
Step 3: Install guest operating system
After the virtual machine is created, you can Install the guest operating system. This can be any operating system such as Windows, Linux, or macOS.
Step 4: Configure virtual machine settings
After creating the virtual machine, you may need to configure some additional settings, such as:
- Sharing Folder
- Snapshots and Backups
- Security Settings
Step 5: Manage Virtual Machine
Install in the virtual machine Once done, you can manage it, including:
- Start and stop virtual machines
- Manage resources
- Clone virtual machines
- Maintenance & Updates
Other Tips
- When installing virtualization software, make sure your system meets the requirements.
- The performance of a virtual machine depends on the resources of the physical host.
- Back up virtual machines regularly to prevent data loss.
- Use the snapshot function to create a backup point of the virtual machine.

CentOS is an open source distribution based on RedHatEnterpriseLinux, focusing on stability and long-term support, suitable for a variety of server environments. 1. The design philosophy of CentOS is stable and suitable for web, database and application servers. 2. Use YUM as the package manager to release security updates regularly. 3. Simple installation, you can build a web server with a few commands. 4. Advanced features include enhanced security using SELinux. 5. Frequently asked questions such as network configuration and software dependencies can be debugged through nmcli and yumdeplist commands. 6. Performance optimization suggestions include tuning kernel parameters and using a lightweight web server.

CentOS is widely used in server management and web hosting. Specific methods include: 1) using yum and systemctl to manage the server, 2) install and configure Nginx for web hosting, 3) use top and mpstat to optimize performance, 4) correctly configure the firewall and manage disk space to avoid common problems.

CentOS is a stable, enterprise-grade Linux distribution suitable for server and enterprise environments. 1) It is based on RedHatEnterpriseLinux and provides a free, open source and compatible operating system. 2) CentOS uses the Yum package management system to simplify software installation and updates. 3) Support advanced automation management, such as using Ansible. 4) Common errors include package dependency and service startup issues, which can be solved through log files. 5) Performance optimization suggestions include the use of lightweight software, regular cleaning of the system and optimization of kernel parameters.

Alternatives to CentOS include RockyLinux, AlmaLinux, OracleLinux, and SLES. 1) RockyLinux and AlmaLinux provide RHEL-compatible binary packages and long-term support. 2) OracleLinux provides enterprise-level support and Ksplice technology. 3) SLES provides long-term support and stability, but commercial licensing may increase costs.

Alternatives to CentOS include UbuntuServer, Debian, Fedora, RockyLinux, and AlmaLinux. 1) UbuntuServer is suitable for basic operations, such as updating software packages and configuring the network. 2) Debian is suitable for advanced usage, such as using LXC to manage containers. 3) RockyLinux can optimize performance by adjusting kernel parameters.

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. Times can be specified as immediate (now), minutes ( minutes), or a specific time (hh:mm). Added information can be displayed in system messages.

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)

Steps to configure IP address in CentOS: View the current network configuration: ip addr Edit the network configuration file: sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0 Change IP address: Edit IPADDR= Line changes the subnet mask and gateway (optional): Edit NETMASK= and GATEWAY= Lines Restart the network service: sudo systemctl restart network verification IP address: ip addr

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
