How do I install XEN, how do I install mysql?

For fedora systems, its package manager is yum, which will be used to install xen from precompiled packages. In fact, installing Xen with Yum is a fairly painless job, and the process is as follows:

1. Install the XEN kernel and related software by the following commands:

yum install kernel-xen xen

kernel-xen: This package stores the xen kernel used by the host operating system, the guest operating system, and the hypervisor.

l Xen: This package stores the user-space tools that interact with the Xen hypervisor.

l bridge-utils: This package contains utilities for configuring an Ethernet bridge, which is used to connect multiple Ethernet devices together.

Libvirt: This package houses a C library that provides the application programming interface APIs needed to use the Xen framework.

l libvirt-python: This package contains a Python module that allows Python applications to use the Xen framework application programming interface provided by libvirt.

l python-virtinst: This package houses a Python module that uses libvirt to install Fedora Red Hat Enterprise Linux in a virtual machine.

l xen-libs: This package holds the libraries required for xen's hypervisor.

First of all, you need to install a Linux suite, such as Ubuntu or CentOS or Redhat, etc., and then go to the Xen official website**Xen source code to compile, and then add Xen to the bootloader, you can choose Xen when you start, and it's OK.

Installation Steps:

1.Double-click the file to start the MySQL installation. The window below appears.

2.Click Next to start the next step of installation. The default is Typical, select Custom, because the Typical mode does not allow you to change the installation path, and can only be installed on the C drive.

3.Select the component and change the folder location, the component can be default, the location should be changed by selecting change (note: the path to install mysql cannot contain Chinese).

MySQL is a relational database developed by MySQL AB in Sweden and is now part of an Oracle company. MySQL is the most popular relational database management system, and MySQL is one of the best RDBMS applications for web applications. MySQL is a relational database management system that keeps data in different tables instead of putting all the data in one large warehouse, which increases speed and flexibility.

The SQL language used by MySQL is the most commonly used standardized language used to access databases. MySQL software has a dual licensing policy (this term"Authorization Policy"It is divided into community and commercial editions, due to its small size, fast speed, low total cost of ownership, especially the characteristics of open source, generally small and medium-sized developers choose MySQL as the database. Due to the excellent performance of its Community Edition, with PHP, Linux and Apache can form a good development environment, after years of web technology development, one of the widely used web server solutions in the industry, called LAMP.

First of all, find your ** system image, if you don't have virtual drive software in your system, and you think that it is more troublesome to use a virtual optical drive, then you can directly use compression software to solve it. Double-click to open.

Then we can see that there are a lot of files and folders inside, and select these files with the left mouse button.

Then right-click to extract to the specified folder, choose one of these locations at random, be careful not to put it on the C drive, and click Start after you are sure.

Now it has begun to decompress, use decompression software to decompress this kind of file, it takes a long time, depending on how your computer is configured, you need to wait patiently, you can also make it run in the background.

Then the extraction is complete, we open the folder where we just extracted, find such an executable program, which is a system disc-like file, and double-click.

At this time, this installation interface will appear, click the Start Installation button to start installing the system.

The following are some specific details of the installation process, just follow the instructions, and the specific installation process is not included in this experience.

Method steps.

Click the Start button behind XenDesktop to go to the next step;

Double-click the Akitaka Virtual Delivery Agent for Windows Desktop OS under the Prepare Machines and Images list to enter the next step;

Select Enable Remote PC Access to proceed to the next step.

The default operation is until the delivery controller of the interface, enter the FQDN of the DDC in the controller address box, click Test Connection, and then click the Add button to enter the next step.

The following are all default, click install to start the installation of the manuscript of the companion (it will be restarted twice during the automatic installation process).

Congratulations, you've successfully installed! (can be viewed in the list of programs).

It is estimated that you are installing it with a USB flash drive, and the above prompt is that the system starts by default to mount the Dev SR0 device (this device is your installation disk or USB flash drive), and then loads the centos7 to be installed from the Dev SR0 device. Since mount can't be mounted on dev sr0, it means that the device can't be mounted, or you don't have the device. In this way, the system is hung in the initramfs file system by default (that is, the basic system kernel is loaded into memory), and when the loading is completed, you can enter shell commands and so on to operate the computer.

You can create a directory mkdir mnt, and then go to dev (cd dev) to view your hardware mapping file, you mount sda(*)sdb(*)sr(*) one by one to mnt, see which ones can be mounted, mount them under mnt to see if it is a centos installation file, if yes, this device file (such as sdb4) is the device file you want to hang when you start up (instead of sr0 as you prompted above), After that, you should know how to boot it, and change the parameters at startup to the device file (sdb4) of your centos installation file, and you can boot to the installation place normally.

Similar to vClient, but generally requires a network file system such as CIFS or NFS, the ISO file is placed on the file system, and the file system is mounted through XenCenter, and the file system will be automatically hung in the future. During installation, the ISO can be mounted from the file system to the virtual machine.
