Installation and use of esxi

    esxi Is designed to run virtual machines 、 Designed to minimize configuration requirements and simplify deployment , It is the industry-leading service virtualization platform , As a basic platform , Ideal for any cloud environment .esxi stay VMware4 First introduced in version , And on and on esx Collectively referred to as vSphere, because vSphere from 5 The version cancels the original esx, It's basically useless now 5 pre-release vSphere, So for now ,esxi Namely vSphere.

2. install esxi

     In the installation esxi Before , Make sure that the physical server is turned on BIOS Virtualization capabilities , Different types of servers operate differently when enabling virtualization , The details can be prepared before startup according to the server you use . Because the author passed in the experimental environment VMwarework Station To deploy , Therefore, we must first deploy esxi Host environment , establish esxi virtual machine .

2.1 establish esxi virtual machine

    establish esxi The virtual machine part is similar to what we use VMware Workstation establish CentOS or Ubuntu virtual machine , But in “ Client operating system ” Part of the choice “VMware ESX(X)”, In addition, later Linux or Windows The system virtual machine is in esxi Deployed on the host , So memory 、CPU And disk space need to be larger , The specific process is as follows .

2.2 install esxi6.7

     After the operation in the previous step , Click on VMware Workstation Start button in esxi6.7 Installation , Press enter after loading to start installation .

    Accept the agreement by f11 agree! ; After scanning the disk, select the disk to use and press enter ; Just leave the keyboard part as default ; Set up root The password link needs to be set 7 Length above bits , And include case 、 Special characters and numbers can be set successfully ;root After setting the password, you can enter the installation process , because esxi It's not very big in itself , So don't wait for a long time , Press enter to restart after installation .

3. Change the default settings

    esxi After restart, some default basic information will be displayed , Because some default settings are not suitable for later virtual machine deployment , It needs to be modified in advance .

3.1 modify IP

    esxi default IP For dynamic access to , This will lead to the failure of the later deployed virtual machine , Therefore, it needs to be modified to static IP. Press f2 Enter root Account and password , That is, the previous installation link is set no less than 7 The number of digits .

     After entering the setup page , Press the up and down keys to “Configure Management Network” part , Enter and select “IPv4 Configuration”, Default dynamic Dynamic acquisition is changed to static Static get （ Press the spacebar to select ）, The default address can be changed if you don't want it .

    Because it's on ssh function , here esxi The host can log in through the remote terminal .esxi The kernel of is very compact , And many commands are also related to Linux The system is the same , Such as the driver is placed in vmfs/devices Under the table of contents ;vmfs/volumes Used for storing various volumes , The virtual machine created later is placed in this directory ;vmfs/volumes/datastore1 Is the default storage directory .

    esxi A very good feature is that it can pass web Interface to login , Input esxi host IP You can enter the login interface , Input esxi The host root The account and password enter the login page , And you can view esxi Information about hosts and virtual machines , Because the author has not installed the virtual machine , So it doesn't show much content , On how to use esxi To create a virtual machine , The author will make a detailed demonstration in the next article .
