3.1.1 Determining user group

To use Web-Based Admin View, you first need to create a user group administered by the operating system for all the nodes, and register a user name.

A specific user group name is defined for each operation management product. A user registers his user name into this assigned user group. This enables the user to limit his operating range.

3.1.1.1 User group type

For details on the user group to be created, refer to the manual of the operation management product.

This section explains about the user group enable to use functions provided as Web-Based Admin View.

wvroot
"wvroot" is a Web-Based Admin View administrator group, and is created automatically when Web-Based Admin View is installed. This permits availability of all kinds of operation management products running on Web-Based Admin View, such as environment setup, logging view, and all. Also, the users belonging to the system administrator (root) can use those products.
Note
As users who belong to wvroot have authority equivalent to those who belong to the system administrator group, you need to register a user group with sufficient care.

When creating the wvroot user group automatically at installation of PRIMECLUSTER, GID (ID number of the group) is not specified. Even if GID is not changed, it does not affect the behavior of the operation management products; however, if you want to specify the same GID between the primary management server and the secondary management server, execute the groupadd(8) command or the groupmod(8) command:

When specifying GID before installing PRIMECLUSTER and then creating the wvroot user group
```
# groupadd -g <GID> wvroot
```
When changing GID of the wvroot user group after installing PRIMECLUSTER
```
# groupmod -g <GID> wvroot
```

3.1.1.2 Register to a user group

Use commands to register user names into the user groups.

Point

Register the user name first, and then, follow up with registration into the user group. The system administrator should initially install by the user name "root."

Note

It's recommended that the user be registered into the wvroot group as the Supplementary Group. In case of registration as a Primary Group, the registration needs to be redone when Web-Based Admin View is uninstalled and installed again.

As a example for inputting user name "wvroot" into the group name as Supplementary Group, the registration way is described ad fallows.

Adding a user group for a registered user
```
# usermod -G wvroot <user name>
```
Registering a new user
```
# useradd -G wvroot <user name>
```
