Wizard Configuration

If you are logging in to ZStack for the first time, you will be guided by the wizard to initialize the basic environment of ZStack Private Cloud in the UI.

Note:

If the initialization process is interrupted, or if you deleted key resources during initialization, the wizard would not be displayed again.
We recommend that you complete the configuration of the ZStack basic environment according to the wizard.

Create Zone

A zone is the largest resource scope defined in ZStack, covering resources such as clusters, L2 networks, and primary storages.

As shown in Create Zone.

Set the following parameters:

Name: Enter a name for the zone.
Description: Optional. Enter a description for the zone.

Click Next to finish creating a zone.

Create Cluster

A cluster is a logical group of analogy hosts (compute nodes).

As shown in Figure 1.

Set the following parameters:

Name: Enter a name for the cluster.
Description: Optional. Enter a description for the cluster.

Click Next to finish creating a cluster.

Add Host

A host, also known as a compute node, is a core asset of the cloud. VM instances run on hosts.

As shown in Figure 1.

For Name, enter a name for the host.
Optional. For Description, enter a description for the host.
For Host IP, enter an IP address for the host, for example, 172.20.14.32.
- For security and stability reasons, we recommend that you separate management networks from public networks in production environments, that is, use separate networks and IP addresses for the management and compute nodes.
  For example, you can use eth0 to connect a set of management networks. ZStack communicates with each compute node through management networks. You can also use eth1 to connect another set of public networks, which can interconnect with external networks through top-level aggregation switches.
- Separating management networks from public networks can ensure the system security as much as possible and provide sufficient network bandwidth for management networks.
For SSH Port, enter the SSH port of the host. Default port: 22. If not specified, the default port will be used.
For User Name, enter the user name of the host. Default user name: root. You can also enter a normal user name as needed.
- If you did not add a user to the host, you can use root as the user name.
- To use a normal user name, make sure that the user has the sudo permission.
- When you create a normal user, we recommend that you the adduser command.
  When you create a normal user and modify the sudo permission of the user, refer to the following example:
```
#Create a normal user named test. [root@localhost ~]# adduser test #Grant the sudo permission to the user test. [root@localhost ~]# echo "test    ALL=(ALL)    NOPASSWD: ALL" >>/etc/sudoers
```
For Password, enter the password of the user. Note that the password is case sensitive.
Click Next. Then, ZStack will configure the host by calling backend jobs.
- The configuration might take several minutes.
- If an error occurs during the installation, the corresponding error message will be displayed.

After you complete the settings according to the wizard, if you want to add other hosts to the same cluster in the same zone, make sure that the corresponding VM instances are installed with the same CentOS operating system. The SSH ports, user names, or passwords of these hosts can be different.
