User accounts in Linux

Super User in Linux

Super User is the user with all rights for accessing all files, Like Windows Administrator. Here the super user is "root".

This user have all rights to access all files including system files. Should be careful if you are root. It can delete any files. So it may crash total system.

The root user can be created at the time of installation.


Adding User in Linux

The root user can add user to Linux box. Following command can be used for adding user in Linux.

[root@LocalHost ~]#useradd kumar

For setup password, Following command can be used,

[root@LocalHost ~]#passwd kumar
Changing password for user kumar.
New UNIX password:
Retype new UNIX password:
passwd: all authentication tokens updated successfully.

You'll get a warning message if you give any dictionary word.
"BAD PASSWORD: it is based on a dictionary word"

You can create user without password, also can disable password for a user. Passwordless account.

[root@LocalHost ~]#passwd -d kumar
Removing password for user kumar.
passwd: Success

For more details use man pages of useradd and passwd.

Every user have home directory as the user name, location is /home/{user name}.


Delete User

Following command is used to delete user,

[root@LocalHost ~]#userdel kumar

It delete user alone, home directory will be avaliable in /home/

For delete home diectory of the user, we use the option -r.
For delete the user forcely , we use the option -f.


User Groups

We can add groups in Linux, Groups are used for permission to accessing files and security. Group have one or more users.

For add group,

[root@LocalHost ~]#groupadd adminnote

When we create a user it automatically create group in the same user name. Every users must be in group, Every user have one primary group and may or may not secondary group. For Example, kumar is the user and he should be in the group kumar, It's primary group of the user kumar. And the user kumar may or may not in the group adminnote.

For checking group of the user, try following command.

[root@LocalHost ~]#groups kumar
kumar : kumar

For more details about this refere some Books of Linux.

Basic in Linux

Linux is one of the operation system. We can tell it as UNIX like operating system. It is open source, It come under GNU public license. We can use it as free. For more and updated details about Linux try Wikipedia.

Now we'll go for learning Linux throw command line, Before go administration these are some basics,

Terminal

The terminal is using for executing commends in Linux box. If we open terminal, it looks as bellow

[kumar@LocalHost ~]$

Here "kumar" is user account in Linux box. "LocalHost" is host name of your system, that means your system name. Normally till (~) symbol mention home directory of the logged user. If you are as root user , it looks as bellow

[root@LocalHost ~]#

Here you can see a difference in both things, that is dollar ($) symbol and Hash (#). There normal user have $ symbol at end and root user have # symbol at the end. This is easily to identify which user we have logged.

Executable commends in Linux are stored in /bin and /sbin directories. The normal user are can access only commends under /bin , They can's use /sbin commends. But the root user can access both /bin and /sbin directory commends.

root is the administrator account. If we made and mistakes while in root account, there is chance to crash hole system.

man:

man is a very basic command in Linux box. We normal know it as man pages. The man pages are manual of commands. most of the commands in Linux have man pages. It describe all about commands. The syntax of the man page is "man {command}"

ex:
[kumar@LocalHost ~]$man ls 

ls:

ls is the basic command in Linux box, ls is used to list files.
ex: 
[kumar@LocalHost ~]$ ls
[kumar@LocalHost ~]$

Here we didn't create any files, so it didn't give any output.

cat:

cat command is used to show the file. And also this is used to create and append the file.

cat {FileName} - Open file
cat > {FileName} - Create file
cat >> {FileName} - Append file
ex:
[kumar@LocalHost ~]$ cat > filename
hi this is my first file

[kumar@LocalHost ~]$ cat filename
hi this is my first file
[kumar@LocalHost ~]$ cat >> filename
this is additional lines

[kumar@LocalHost ~]$ cat filename
hi this is my first file
this is additional lines
[kumar@LocalHost ~]$

"ctrl + c" used to quit file, It'll save and exit from cat.

We can't edit already created file with "cat" command. For this we are going for other editors available in Linux.
ex: vi, vim etc.,

Before we going to editors we'll see the "ls" command, As seen before ls is the command used for list file in Linux,

[kumar@LocalHost ~]$ ls
filename
[kumar@LocalHost ~]$

This is the file we created as before by "cat".
ex:

[kumar@LocalHost ~]$ ls -l
total 4
-rw-rw-r-- 1 kumar kumar 50 Aug  3 11:47 filename

Here -l is the option for ls command, It give some detailed information about the file or directory.

"total 4" is blocks used by the file "filename".

"-rw-rw-r--" is about file permission, we'll see about it later.
"1" is about file count.
"kumar" is owner of file
"kumar" is group under this file
"50"  file size
"Aug 3 11.47" file creation date and time
"filename" name of the file

for more option try man pages and try more,

mkdir:

mkdir is the command used to create folder in Linux box.
ex:
[kumar@LocalHost ~] mkdir myfolder

rm:

rm is the command used to remove folder or file.
ex:
rm {filename}

options:
-f used to force the deletion, it won't ask conformation
-r used for recursive deletion, i meant it used to delete entire folder

[kumar@LocalHost ~] rm -f filename
[kumar@LocalHost ~] rm -fr myfolder

vim:
vim is the editor, It is advance version of the vi editor. vim editor can be used to create, edit and update file.

ex:
[kumar@LocalHost ~] vim newfile

It'll open editor window, Normally it in uneditable mode. By press "i" key we can move to edit mode, to quit from edit mode, press "esc" key.
After finish typing, press "esc" key and type ":wq" for save and quit. Here w for save and q for quid vim. We can use this command separately. For quit without changes, ":q!".

For more options try man pages.

Add module (driver) while installing RHEL 5

It's an interview question for Linux System Administrator,

You want to install RHEL 5 operating system on server machine. Unfortunately RHEL 5 doesn't detect your hard disk. But you need to install it on that hard disk. How will you do ? You have module disk ( Driver CD/DVD) for that hard disk and RHEL 5 DVD.

I felt this is too hard and searched in several places, But actually it's simple thing, ( I didn't try practically because i don't have that much advance or old hard disk). Ok let us see those very simple steps.

Step 1 : Insert the RHEL 5 CD/DVD and boot from CD/DVD. We will get following screen,

Redhat Boot Screen

click image for zoom

Step 2 : There is submenu , Press F2 for show Installer boot options, It's look like as bellow,

Installer Boot Options

click image for zoom

 
Step 3 : Type "linux dd" and hit enter, you'll get following screen. "linux dd" use to load driver disk,

Driver Disk

click image for zoom

 
Step 4 : It asks whether you have driver disk or not. Select Yes and hit enter. you'll get following screen.

Insert Driver Disk

click image for zoom

Step 5 : Insert your Driver Disk and hit enter. It'll install needed driver from disk.

Now your Hard Disk is detected by the RHEL 5 CD/DVD. Now we can install OS in this Hard Disk.

* Still I not use this method. Hope this will work. If you face this problem. Try and commant me.
