mkdir permissson denied [Solved]

[PhaseMaster]

Hello,

My OS is Ubuntu 11. I am trying to install XAMPP 1.7.7.

I entered “su,” my user name, and my password at the command line. This procedure worked as expected. Then I entered the following command:

Code: Select all

tar xvfz xampp-linux-1.7.7.tar.gz -C /opt

The console put out many lines of text, with a frequent error message of:

Code: Select all

tar: lampp: Cannot mkdir: Permission denied

This refers to making the LAMPP directory in OPT. How do I gain permission to mkdir in OPT?

Regards,

Ben

there are two possibilities

A. - your 'su' command did not work as expected -

did your prompt change to something like this???

Code: Select all

[jonb@localhost ~]$ su
Password:
[root@localhost jonb]# 

For 'su' (unlike sudo) the pw is the 'root' user's password, not your password (unless they happen to be the same) (just saying).
and - your prompt should change - the 'jonb' in [root@localhost jonb]# is the tail of the present working directory which was /home/jonb

B. something wierd has happened, that I cannot grok right now.

With linux you must be terribly careful of case, so when you reference folder names, be sure to type them exacly as you used them in the command line, or code.

This refers to making the LAMPP directory in OPT.

so that is not 'right'... it leads to big confusions.

Thanks and Good Luck

Here is my command line input and output:

Code: Select all

ben@ben-Dell-XPS420:~$ su ben
Password:
ben@ben-Dell-XPS420:~$ mkdir /opt/lampp
mkdir: cannot create directory `/opt/lampp': Permission denied
ben@ben-Dell-XPS420:~$

"no, no, no'"

You must be 'root' - not 'ben'. Note your prompt did not change...

by placing 'ben' on the argument line with no other arguments you are affecting NOTHING. because you already ARE 'ben'

the command is exactly as I put in the last post.

Code: Select all

[jonb@localhost ~]$ su
Password:
[root@localhost jonb]#

see there is no 'jon', on the su command line...

The su command changes user credentials to those of the root user or to the user specified by the Name parameter, and then initiates a new session

make that change and it should work.

Good Luck
