Basic Account Administrations-How To-Linux OS

Add existing user called example user <Uyxx> to the wheel group

By default, all users on a Linux distribution can use the su (switch user) command to become another user during a login session. If no username is given, su defaults to becoming the super user. While on other UNIX systems, one must be in the wheel group in order to access the su command.

This tutorial will show you how to restrict the use of su command on Linux so that only users in the wheel group have access to it.

The wheel group is a special user group on Unix-like systems to restrict access to su command. The term wheel comes from the archiaic slang phrase “big wheel” which means an important and influential person.
Edit /etc/pam.d/su config file:

sudo vi /etc/pam.d/su
add the following line:

auth required /lib/security/pam_wheel.so use_uid
or

auth required pam_wheel.so use_uid
Save and close the file.

Now when a user that is not in the wheel group try to use su command, he/she will get a permission denied error, even if the password is typed correctly.

If you want to add a user to the wheel group, use the following command:

sudo usermod -G wheel username
Use the id command to check if the user is in the wheel group

id username

The syntax is:

pw group mod {GROUP-NAME-HERE} -m {USERNAME-HERE}
pw group mod wheel -m Uyxx
If the user named Uyxx already exists add her to the wheel group.

Add new user called sai while creating a new account

The syntax is:

pw user add {USERNAME-HERE} -G {GROUP-NAME-HERE}
pw user add sai -G wheel
The above command creates the sai primary group automatically, and add a user in the wheel group when her account is first created on a FreeBSD unix operating systems.

How do I verify new group membership on a FreeBSD?

The syntax is:

pw groupshow {GROUP-NAME-HERE}
pw groupshow wheel
pw groupshow sai
pw groupshow vivek
## Determine Group Membership Of sai and vivek Users ##
id sai
id vivek

How To Set up New SUDO User-Linux OS 

The sudo command provides a mechanism for granting administrator privileges, ordinarily only available to the root user, to normal users. This guide will show you the easiest way to create a new user with sudo access on CentOS, without having to modify your server’s sudoers file. If you want to configure sudo for an existing user, simply skip to step 3.

Steps to Create a New Sudo User
Log in to your server as the root user.

ssh root@server_ip_address
Use the adduser command to add a new user to your system.

Be sure to replace username with the user that you want to create.

adduser username
Use the passwd command to update the new user’s password.

passwd username
Set and confirm the new user’s password at the prompt. A strong password is highly recommended!

Set password prompts:
Changing password for user username.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
Use the usermod command to add the user to the wheel group.

usermod -aG wheel username
By default, on CentOS, members of the wheel group have sudo privileges.

Test sudo access on new user account

Use the su command to switch to the new user account.

su – username
As the new user, verify that you can use sudo by prepending “sudo” to the command that you want to run with superuser privileges.

sudo command_to_run
For example, you can list the contents of the /root directory, which is normally only accessible to the root user.

sudo ls -la /root
The first time you use sudo in a session, you will be prompted for the password of the user account. Enter the password to proceed.

Output:
[sudo] password for username:
If your user is in the proper group and you entered the password correctly, the command that you issued with sudo should run with root privileges.

How To Extend a Logical Volume On Linux OS-Virtualize Environment.

To extend the logical volume on Linux OS

Purpose/Scope
This article provides steps for extending the root partition residing in a logical volume created with Logical Volume Manager (LVM) in a virtual machine running Red Hat/CentOS.

Caution: Always take a complete backup of the virtual machine prior to making these changes.
1.Power off the virtual machine.
a. Click Edit the virtual machine settings and extend the virtual disk size.

b. Increase size of the disk volume
c. Power on the virtual machine.

d.Open Shell Windows 

will be using PVS, VGS and LVS 

e. Identify the device name, which is by default /dev/sda, and confirm the new size by running the command:

# fdisk -l

f.Create a new primary partition:
Run the command:

# fdisk /dev/sda (depending the results of the step 4)
Press p to print the partition table to identify the number of partitions. By default, there are 2: sda1 and sda2.
Press n to create a new primary partition.
Press p for primary.
Press 3 for the partition number, depending on the output of the partition table print.
Press Enter two times.
Press t to change the system’s partition ID.
Press 3 to select the newly creation partition.
Type 8e to change the Hex Code of the partition for Linux LVM.
Press w to write the changes to the partition table.

Restart the virtual machine.
Run this command to verify that the changes were saved to the partition table and that the new partition has an 8e type:

# fdisk -l

Run this command to convert the new partition to a physical volume:

Note: The number for the sda can change depending on system setup. Use the sda number that was created in step 5.

# pvcreate /dev/sda3

Run this command to extend the physical volume:

# vgextend VolGroup00 /dev/sda3

Note: To determine which volume group to extend, use the command vgdisplay.

Run this command to verify how many physical extents are available to the Volume Group:

# vgdisplay VolGroup00 | grep “Free”

Run the following command to extend the Logical Volume:

# lvextend -L+#G /dev/VolGroup00/LogVol00

Where # is the number of Free space in GB available as per the previous command. Use the full number output from Step 10 including any decimals.

Note: To determine which logical volume to extend, use the command lvdisplay.

Run the following command to expand the ext3 filesystem online, inside of the Logical Volume:

# ext2online /dev/VolGroup00/LogVol00

Notes:
Use resize2fs instead of ext2online if it is not a Red Hat virtual machine.
By default, Red Hat and CentOS 7 use the XFS file system you can grow the file system by running the xfs_growfs command.

Run the following command to verify that the / filesystem has the new space available:

# df -h /
