Create/delete a server

[Update: November 29, 2018]

Procedures for creating or deleting a server on SAKURA Cloud

On SAKURA Cloud, servers, disks, networks, and other elements are provided in a virtual state. At the same time as creating a server, you can create one disk, copy an OS image using Public archive , and configure settings for connecting to shared segments. Therefore, the server that you create can be connected to the Internet immediately.

Note

As for Connect disk for two or more disks or Add NIC for two or more NICs, separate settings must be configured after creating the server. Furthermore, if you want to connect to Switch , you must create the switch to serve as the connection destination in advance.

Procedures for creating a server

1. Display the server management screen

Log in to the Control panel . Select Account for operation and click [SAKURA IaaS].

From the zone selection menu at the top-left, select the zone in which you want to create server.

Attention

In addition to the server, the creation of new disks, switches, etc., and the list display of resources that have already been created all depend on the zone which is currently selected. Except for some functions, it is impossible to connect servers and disks, or to connect to switches in other zones. The currently selected zone is always displayed at the top-left of the control panel screen. Please confirm that you are using the desired zone when performing operations.

Click [Server] from the menu on the left.

The server list screen is displayed for servers that have been created in the selected zone. To create a new server, click [Add] at the top of the list.

2. Operations for creating a new server

Simple mode is selected as the default. In simple mode, you can easily create a server by selecting options from several menus and entering information. If you want to create a server using more detailed conditions (for example, if you only want to create a server without simultaneously creating a disk, or if you want to use an ISO image and install the OS from the console screen), please remove the check from the [Simple Mode] checkbox at the top-right of the screen and perform operation using Normal mode .

Select and enter information for the following items displayed on the create new screen, and then configure settings for the server that you want to create.

Disk image

Public archive is a disk image with an OS installed in advance. By copying the public archive to the disk that is created simultaneously with the server, you can create a disk that can be booted immediately without any troublesome OS installation procedures. SAKURA Cloud has menus which can be used to create disks which are already installed with OS. The main option is Linux OS that is widely used for servers. Other options include paid Windows OS. In addition to an OS, server applications are also available.

The following items can be selected from the tabs at the top of the screen.

  • You can select from Unix/Linux: CentOS, FreeBSD, and other open source Unix OS which are widely used for servers and can be used free of charge.
  • You can select Windows: Windows Server. Separate license fees will be incurred. For details, please refer to the Windows server page.
  • Application: In addition to the base OS, installation of applications and setup is automatically performed by the Startup script function. Depending on the selected application, [Settings] items are automatically added at the bottom of the screen.
  • My Archive: Instead of the contents of the public archive prepared in advance by SAKURA Cloud, contents of the archive created by the customer from the existing disk are copied to the disk.
  • My Disk: A disk is created using the same contents as an arbitrarily-specified disk that has already been created.

Hint

Depending on the selected OS and application, you can specify a detailed version from the pop-up menu displayed under the icon.

Server plan

Select a plan for the server that you want to create. Plans which are not displayed can be selected by clicking the [Select from All Items] button.

Disk plan

Select a plan for the disk that you want to create. Plans which are not displayed can be selected by clicking the [Select from All Items] button.

Settings

When [Application] has been selected for the disk image, there are cases in which items for entering application settings values are displayed. The entered settings values are updated to settings for the application that is installed.

Connected network

Click either [Internet] or [Switch]. Selecting [Switch] will display the Switch selection screen that has already been created. After the server is created, it will be connected to the selected switch.

Server settings

You can use Disk modification function to set the admin password and public key at the time of server creation.

Admin password You can set the passwords for priviledged users who will be server administrators. For example, you can set "root" for CentOS and "ubuntu" for Ubuntu.
Public key By registering a public key, you can log in to the server using public key authentication method from the first time that the server is used.
Public key registration is performed using either of the following methods by selecting radio buttons.
Entry: Direct entry of the public key in the displayed text area.
Select from cloud account: Select a public key which has already been registered in the control panel.
*For details, please refer to the Public key authentication page.
Acquire from github.com Username: Select from SSH public keys registered by a user who is registered in GitHub.
*If the user does not exist or the SSH key is not registered, an error will occur and the operation will fail.
*If multiple public keys exist, all public keys are registered.

Adding a license

If the plan for Windows Server remote desktop service (RDS) is selected for disk image, an item is displayed for setting license types which can be used with the selected plan and for setting the number of licenses.

In accordance with the number of RDS clients, etc., connected to the server, you can purchase the required licenses at the same time as creating the server. For details, please refer to the Remote desktop plan page.

Host name

Enter the name of the host for which you want to configure settings. The entered host name is set to the OS via the ref: Disk modification function <modifydisk> .

Creation number

"1" is set as the default value. However, you can create multiple servers with the same settings as the settngs configured via the entry forms as described until the previous section. (The end of the host name is accompanied by the number of created resources in a sequential order.)

3. Execute creation

The confirmation screen is displayed. Check that everything is correct and then click [Create].

Click the [Display Details] button to check the specifications of the server and disk specified in the form, and to check a breakdown of fees depending on factors such as the number of licenses.

4. Completion of server creation

Creation of the server starts after you press the [Create Server] button. Normally, server creation is finished within several minutes. Server creation is finished when [Successful] is displayed for the status. Click the [Close] button to return to the control panel screen.

Operation in normal mode

When you remove the check from the [Simple Mode] checkbox at the top-right of the server creation screen, normal mode is used. In normal mode, you can use all of the functions for server creation operation.

Server plan

You can use the radio buttons to select a server plan. The number of selectable memories changes depending on the number of virtual cores selected.

Clicking the [Select from Server Plan List] button will display a list of plans with all selectable combinations for the number of virtual cores and the number of memories. You can select directly from this list.

Disk

In addition to creating a new disk together with the server, you can connect a disk that has already been created, select an option to create only a server without creating a disk, etc. The latter option is convenient when using a bootable CD.

When creating a disk together with the server, you can select from the following options for the disk source: a public archive, my archive using an archive created by the user, a copy from an existing disk, or a blank that connects a plain disk without any contents.

When selecting [Create New Disk]

Disk plan You can select from two types of disks: an SSD plan which is advantageous for disk I/O performance, or a standard plan that is usable at low cost.
*For details on specific performance, please refer to This FAQ page .
Disk source When copying disk contents, you can select a public archive, an archive created by the customer, or a copy of contents from an existing disk as the copy source.
*If you want a blank disk without any contents written, select [Blank].
Disk size Select the disk size to create.
*The selectable size may differ depending on the plan.
Option: [Store in Different Storage] When a check is inserted into the checkbox for this option, a disk selection pop-up menu is displayed. Storage will be performed in a different storage device from the disk specified here.
This is convenient for cases such as improving fault resistance by storing in a different storage location from disks of other servers with redundant configurations.
Option: [Use Paravirtualization Mode (Virtio)] Normally, a check is inserted into the checkbox for this item as default, and the Virtio driver is used for connecting the server and disk. If the check is removed, the IDE emulation driver will be used.
Please remove the check when necessary, such as when using an OS that is not compatible with Virtio.

Note

When using an ISO image to install the OS from the installer, using ISO image boot to start a server without using a disk, etc., please select [Blank] for the disk source.
Making these selection will display a selection menu for ISO image to be inserted in the server.

When [Connect Existing Disk] is selected

Select a created disk that you want to connect to the server being created.

Attention

No disk connected to the server is displayed and it is not possible to connect. If you want to use the same disk contents, select [Create New Disk] and then select the disk to use as the copy source.

When [Diskless (None)] is selected

Select when you want to create a server only. If you want to boot from the ISO image, you can also create a server with the ISO image selected at the ISO image selection menu inserted.

NIC

You can select from the following for the server NIC connection destination: Connect to the Internet (shared line), connect to a switch already created by the user, or do not connect to anything (disconnected state).

You can also select VirtIO connection which is capable of high-efficiency data I/O in the virtual environment (normally, it is enabled as default).

Disk modification

You can use the Disk modification function to change the contents of the disk connected to the server. (Not displayed when no disk is connected to the server or when a blank disk is connected.)

Admin password Enter the password that you want to set for the OS administrative user ("root" user for CentOS, "ubuntu" for Ubuntu, etc.).
Host name Enter the host name to set for the OS.
Public key You can register a public key in advance for cases such as when you want to use a public key to log in to the OS.
*When settings have been configured to register a public key, the [Prohibit SSH Login Via Password/Challenge Response] option is displayed. When a check is inserted into the checkbox for this option, settings will be simultaneously configured to disable SSH login via an authentication method other than the public key.

Public key registration is performed using either of the following methods by selecting radio buttons.
Entry: Direct entry of the public key in the displayed text area.
Select from cloud account: Select a public key which has already been registered in the control panel.
*For details, please refer to the Public key authentication page.
Acquire from github.com Username: Select from SSH public keys registered by a user who is registered in GitHub.
