[Updated in 2013] I need to update this article. Please note that a large number of IDC currently provide KVM The product can not only complete the system installation step by step like the following tutorial, but also provide one click installation (reinstallation) of the system. It is not fussy, troublesome, and in a hurry The same is true for direct reinstall~~~
Recently, I met some friends who bought KVM architecture products and left a message, saying that they had met a bad father. They could not log in through SSH after buying KVM and could not ping, and so on. In fact, this is due to the ignorance of KVM architecture products. Compared with OpenVZ and XEN (PV), KVM has greater autonomy. When we buy a KVM that is only equivalent to a bare metal machine, and has no operating system, when we get it, we should first install the operating system through the VPS management panel, and then connect and use it. A long time ago, I wrote a simple procedure to install Debian on Hostization KVM（ Antecedent review ）Today, I'm here to share about KVM installation CentOS To give you a reference.
Friendly tip: There are many pictures in this article, which have been loaded for a long time. Please understand.
First, we log in to the SolusVM panel, set the optical drive to start, and put the CentOS ISO file in the optical drive.
As shown in the following figure, I am going to install CentOS5.8. Here, I can choose Full CD or Netinstall (one is direct ISO, the other is network installation). Here, I take a screenshot of the selected CD installation, but later I used Netinstall. Note that the basic steps are the same.
After finishing the above work, restart VPS, and then click the VNC connection on the panel.
Please note that the VNC connection of the panel requires the browser JAVA support. Please install the browser plug-in yourself. You can also use the VNC tool to view the VNC link information on the panel.
OK, this is the VNC installation interface. We choose the text mode to start the installation.
The following figure is the page for selecting CD installation. It prompts you to find the CD and asks if you need to detect it. This is not necessary. You can simply click Skip.
If you use the CD to install directly, the following two steps will not appear. I will take the network installation as an example, and the following interface will appear. First configure TCP/IP, and then use the default.
Enter the network installation source address. We can find many installation sources in the search engine.
The Welcome screen appears.
Since I already have a system here, I have one more choice. I choose to reinstall the system.
Next, you can define partitions and select disks.
Disk partition adjustment.
Start item management configuration.
Hostname configuration, which can not be set temporarily.
I choose Asia/Chongqing as the time zone.
Password setting of the root account.
Optional installation package.
This is a prompt indicating that the installation is about to begin.
Format the disk and file system.
OK， Installation started.
The above is the process of starting the installation. After the installation is completed, there will be a prompt to restart the page. I will not take a screenshot. OK and restart.
After restarting, the user will go to the login interface and log in with the root password we set.
I installed CentOS6.3 once more, which is also Netinstall. Due to space limitations, I will not elaborate one by one. I will send screenshots of the process to the space. You can download the compressed package of screenshots to watch: Click to download the screenshot tutorial of KVM installation CentOS6
The above is the basic process of installing CentOS by KVM. There are many pictures and some missing screenshots, which are relatively simple. If you cannot push the connection, check whether the SSHD service is enabled and whether the iptables rule is abnormal.
