OCM_Session7_2_创建组，用户，设置用户密码

二、创建组，用户，设置用户密码

在OCM环境中，用户和用户组也已经配置好。我们只需要查看 id oracle。

2.4.6 Creating Identical Users and Groups on Other Cluster Nodes

Note:
You must complete the following procedures only if you are using local users and groups. If you are using users and groups defined in a directory service such as NIS, then they are already identical on each cluster node.
The
Oracle software owner user and the Oracle Inventory, OSDBA, and OSOPER groups must exist and be identical on all cluster nodes. To create these identical users and groups, you must identify the user ID and group IDs assigned them on the node where you created
them, then create the user and groups with the same name and ID on the other cluster nodes.

Identifying
the User and Group IDs
To determine the user ID (UID) of the Oracle software owner user and the group IDs (GID) of the Oracle Inventory, OSDBA, and OSOPER groups, follow these steps:

Enter following command:

# id oracle
The output from this command is similar to the following:

uid=440(oracle) gid=200(oinstall) groups=201(dba),202(oper)

From the output, identify the user ID (UID) for the

oracle

user and the group identities (GIDs) for the groups to which it belongs.

Creating the User and Groups on the Other Cluster Nodes
To create the user and groups on the other cluster nodes, repeat the following procedure on each node:

Log in to the next cluster node as

root

.

Enter commands similar to the following to create the

oinstall

and

dba

groups, and if required, the

oper

group. Use the

-g

option
to specify the correct GID for each group.

# /usr/sbin/groupadd -g 200 oinstall

# /usr/sbin/groupadd -g 201 dba

# /usr/sbin/groupadd -g 202 oper

Note:
If the group already exists, then use the

groupmod

command to modify it if necessary. If you cannot use the same group ID for a particular group on this node, then view the

/etc/group

file
on all nodes to identify a group ID that is available on every node. You must then specify that ID for the group on all of the nodes.

To create the

oracle

user, enter a command similar to the following:

# /usr/sbin/useradd -u 200 -g oinstall -G dba[,oper] oracle
In the preceding command:

The

-u

option specifies the user ID, which must be the user ID that you identified in the previous subsection

The

-g

option specifies the primary group, which must be the Oracle Inventory group, for example

oinstall

The

-G

option specifies the secondary groups, which must include the OSDBA group and if required, the OSOPER group. For example:

dba

or

dba,oper

Note:
If the

oracle

user already exists, then use the

usermod

command to modify it if necessary. If you cannot use the same user ID for the

oracle

user
on this node, then view the

/etc/passwd

file on all nodes to identify a user ID that is available on every node. You must then specify that ID for the user on all
of the nodes.

Set the password of the

oracle

user:

# passwd oracle
