Hello Pian, and others lucky readers who are reading and trying to net-install centos The tutorial is suggesting a wrong URL. Your name or email address: Do you already have an account? For example, represent September as For example, represent the subdomain storage.

A colon followed by a string that uniquely identifies this particular iSCSI initiator within your domain or subdomain. For example, :diskarrays-sn-a A complete IQN is as follows: iqn.

The installation program prepopulates the iSCSI Initiator Name field with a name in this format to help you with the structure. For more information about IQNs, see 3. The following options are available:. The installation program attempts to discover an iSCSI target based on the information provided. The Node login authentication type menu contains the same options as the Discovery Authentication Type menu.

However, if you need credentials for discovery authentication, use the same credentials to log in to a discovered node. Click the additional Use the credentials from discovery drop-down menu. When you provide the proper credentials, the Log In button becomes available.

Enable this option only for network interfaces that require a host-based DCBX client. For configurations on interfaces that use a hardware DCBX client, disable the check box. Additionally, if the device meets the requirements for booting, you can set the device as a boot device.

You can use manual partitioning to configure your disk partitions and mount points and define the file system that CentOS is installed on. Before installation, you should consider whether you want to use partitioned or unpartitioned disk devices. You can also create additional partitions and volumes as you require. Click Installation Destination to open the Installation Destination window. Select the disks that you require for installation by clicking the corresponding icon.

A selected disk has a check-mark displayed on it. If you selected to encrypt the storage, a dialog box for entering a disk encryption passphrase opens. Type in the LUKS passphrase:.

Deleted Mount points are listed in the left-hand pane. The mount points are organized by detected operating system installations. As a result, some file systems may be displayed multiple times if a partition is shared among several installations. Select the mount points in the left pane; the options that can be customized are displayed in the right pane. If your system contains existing file systems, ensure that enough space is available for the installation. To remove any partitions, select them in the list and click the - button.

The dialog has a check box that you can use to remove all other partitions used by the system to which the deleted partition belongs. If there are no existing partitions and you want to create the recommended set of partitions as a starting point, select your preferred partitioning scheme from the left pane default for CentOS is LVM and click the Click here to create them automatically link.

These are the recommended file systems for a typical installation, but you can add additional file systems and mount points. Click Done to confirm any changes and return to the Installation Summary window. Continue with adding mount points , configuring the individual mount points , and configuring the underlying partitions or volumes. If you want to install the system on multiple disks, or if your disks differ in size and a particular partition must be created on the first disk detected by BIOS, then create these partitions first.

The Add a New Mount Point dialog opens. Enter the size of the file system in to the Desired Capacity field; for example, 2GiB. If you do not specify a value in the Desired Capacity field, or if you specify a size bigger than available space, then all remaining free space is used.

Click Add mount point to create the partition and return to the Manual Partitioning window. This procedure describes how to set the partitioning scheme for each mount point that was created manually. To change the devices that a single non-LVM mount point should be located on, select the required mount point from the left-hand pane. The Configure Mount Point dialog opens.

Select one or more devices and click Select to confirm your selection and return to the Manual Partitioning window. Click the Rescan button circular arrow button to refresh all local disks and partitions; this is only required after performing advanced partition configuration outside the installation program.

Clicking the Rescan Disks button resets all configuration changes made in the installation program. In the lower left-hand side of the Manual Partitioning window, click the storage device selected link to open the Selected Disks dialog and review disk information. In some situations, such as when these directories are placed on an iSCSI drive or an FCoE location, the system is unable to boot, or hangs with a Device is busy error when powering off or rebooting.

Enter the file system mount point into the Mount Point field. For a swap file system, do not set the mount point as setting the file system type to swap is sufficient. Enter the size of the file system in the Desired Capacity field. You can use common size units such as KiB or GiB. The default is MiB if you do not set any other unit.

RAID is available only if two or more disks are selected for partitioning. Select the Encrypt check box to encrypt the partition or volume. You must set a password later in the installation program. Select the appropriate file system type for this partition or volume from the File system drop-down menu. Select the Reformat check box to format an existing partition, or deselect the Reformat check box to retain your data.

The newly-created partitions and volumes must be reformatted, and the check box cannot be deselected.

Type a label for the partition in the Label field. Use labels to easily recognize and address individual partitions. Note that standard partitions are named automatically when they are created and you cannot edit the names of standard partitions. Click Update Settings to apply your changes and if required, select another partition to customize. Changes are not applied until you click Begin Installation from the Installation Summary window.

Click Done when you have created and customized all file systems and mount points. If you choose to encrypt a file system, you are prompted to create a passphrase. A Summary of Changes dialog box opens, displaying a summary of all storage actions for the installation program. Click Accept Changes to apply the changes and return to the Installation Summary window. Under Storage Configuration , select the Custom radio button. Click Done. After you customized all partitions according to your requirements, click Done.

The Summary of changes dialog box opens. Click Accept Changes to apply the changes, and return to the Installation Summary window. RAID devices are constructed from multiple storage devices that are arranged to provide increased performance and, in some configurations, greater fault tolerance. A RAID device is created in one step and disks are added or removed as necessary. You can configure one RAID partition for each physical disk in your system, so the number of disks available to the installation program determines the levels of RAID device available.

For example, if your system has two hard drives, you cannot create a RAID10 device, as it requires 4 separate partitions. You have selected two or more disks for installation before RAID configuration options are visible. At least two disks are required to create a RAID device.

You have selected the Custom radio button on the Installation Destination window. From the left pane of the Manual Partitioning window, select the required partition. Under the Device s section, click Modify. The Configure Mount Point dialog box opens. Click the File System drop-down menu and select your preferred file system type. A message is displayed at the bottom of the window if the specified RAID level requires more disks.

Partitions on physical storage are represented as physical volumes that you can group together into volume groups. You can divide each volume group into multiple logical volumes, each of which is analogous to a standard disk partition. Therefore, LVM logical volumes function as partitions that can span multiple physical disks. During text-mode installation, LVM configuration is not available. The Volume Group drop-down menu is displayed with the newly-created volume group name.

The size is always set to the default value of 4 MiB. See the Performing an advanced installation document for more information about Kickstart. From the left-hand pane of the Manual Partitioning window, select the mount point. From the Size policy drop-down menu, select the size policy for the volume group.

Automatic : The size of the volume group is set automatically so that it is large enough to contain the configured logical volumes. This is optimal if you do not need free space within the volume group. As large as possible : The volume group is created with maximum size, regardless of the size of the configured logical volumes it contains. This is optimal if you plan to keep most of your data on LVM and later need to increase the size of some existing logical volumes, or if you need to create additional logical volumes within this group.

Fixed : You can set an exact size of the volume group. Any configured logical volumes must then fit within this fixed size. This is useful if you know exactly how large you need the volume group to be. Click Save to apply the settings and return to the Manual Partitioning window. Before you start the installation program, you must configure your root password and user settings.

When the installation process has started, it is not possible to return to the Installation Summary window and change any settings. To change settings, you must wait for the installation process to finish, reboot your system, log in, and change your settings on the installed system. You have completed all configuration steps in The Installation Summary window. From the Installation Summary window, click Begin Installation.

The Configuration window opens and the installation process starts. Two user setting options, Root Password mandatory and User Creation optional are available. Before you finish the installation and reboot, either remove the media CD, DVD, or a USB drive used to start the installation, or verify that your system tries to boot from the hard drive before attempting removable media. Otherwise, your system starts the installation program again, instead of the installed system.

You must configure a root password to finish the installation process and to log in to the administrator also known as superuser or root account that is used for system administration tasks. These tasks include installing and updating software packages and changing system-wide configuration such as network and firewall settings, storage options, and adding or modifying users, groups and file permissions. Create a user account with administrative privileges member of the wheel group.

The root account is always created during the installation. Switch to the administrator account only when you need to perform a task that requires administrator access.

The root account has complete control over the system. If unauthorized personnel gain access to the account, they can access or delete users' personal files.

From the Configuration window, click Root Password. The Root Password window opens. Click Done to confirm your root password and return to Beginning installation. It is recommended that you create a user account to finish the installation. If you do not create a user account, you must log in to the system as root directly, which is not recommended. From the Configuration window, click User Creation.

The Create User window opens. The User name is used to log in from a command line; if you install a graphical environment, then your graphical login manager uses the Full name. Select the Make this user administrator check box if the user requires administrative rights the installation program adds the user to the wheel group. An administrator user can use the sudo command to perform tasks that are only available to root using the user password, instead of the root password.

This may be more convenient, but it can also cause a security risk. If you give administrator privileges to a user, verify that the account is password protected. Never give a user administrator privileges without assigning a password to the account. Save Changes to apply the changes and return to the Configuration window. When the installation process is complete, click Reboot to reboot and log in to your CentOS 8 system. Follow the steps in this procedure to edit the default settings for the user account in the Advanced User Configuration dialog box.

Edit the details in the Home directory field, if required. The default value is GIDs are reserved by the system so they can not be assigned to a user group. Specify additional groups as a comma-separated list in the Group Membership field.

Groups that do not already exist are created; you can specify custom GIDs for additional groups in parentheses. Click Save Changes to apply the updates and return to the Configuration window. If your system was installed on a workstation with the X Window System, applications to configure your system are launched. These applications guide you through initial configuration and you can set your system time and date, and more. If the X Window System is not installed, a login: prompt is displayed.

To learn how to complete initial setup, register, and secure your system, see Completing post-installation tasks. If your system does not have the ability to use the graphical mode, you can:.
