Server :: How To Reset Root Password For Redhat Machine
Oct 25, 2010
Yesterday, when I was installing Redhat Enterprise 5.4 on a HP server, I asked myself "how can I regain my access to the server if I happen to forget the root password?" I knew there must be a way. I consulted with my friend "Google". I'd like to share it here as my 1st post (too bad that I'm not allowed to paste screenshots)
1) Boot up the server, when you are at the "Red Hat Enterprise Linux Server..." entry, press "e".
2) Highlight the "kernel /vmlinuz...." line then press "e" again.
3) Type the word "single" to the end of the line (with an empty space before the word single). Press Enter.
4) Press "b"
5) System will boot. When you get the prompt "#", type "passwd" to enter in new password for root.
6) Reboot the system. Done
I am an absolute Linux Beginner who is being required to do a bit of admin work because the boss just fired the old linux admin. Unfortunately, one of our employees cannot remember her password to her email account and as such I need to reset it on our linux server.What I want to check is that this email account is actually a linux user account and I simply will reset the password for it using the passwd command from the root login. Is that correct?
for resetting the root user's password. Actually, I am using www.linuxzoo.net for online practice of Linux and have MySQL installed on it. But I forgot the password I set. There was no password by default set for the root user. So, I just trying setting a password last week. Now I am not getting what I did.
I am using RHEL 5.4 my root password is getting reset after every reboot.every time i had to change the password from kernel to access the root.i am unable to find the where the problem is.
I try to access my ubuntu machine via my Windows Machine (Samba Server on Ubuntu Machine). Anytime I try to access the machine it asks me for my password...I enter it but it says it is invalid....is there anyway to reset it? I have already tried to remove and purge everything Samba related and then tried reinstalling, but that still didn't do anything
I am trying to set up a webserver with apache, mysql and php on a old pentrium 4 computer. When I tried to setup my MySQL password, I created a password with punctuation in it. MySQL didn't want the password and gave some error about BASH. I tried changing my password again but now I constantly get the error that I am unable to login. I tried all the possibilities with the password I entered before but i just can't login to MySQL anymore. I found some help sites on how to reset your password by running MySQL in the safe mode but that didn't work for me. Can anyone help me resetting my password? Next time i'll use a pass without punctuation Every help is much appreciated! BTW, I also tried uninstalling MySQL with yum (yum remove mysql) and it uninstalled, but when I installed it again the password was still there
I've installed UBUNTU 9.10 on ( windows 7 ) when I was interested to discover Linux, now I began to understand this AWESOME system and I began to get ride of Microsoft " Windows " .. But I face a problem that when I installed It I created only one account with a password, but It's not the root, when I tried to login as root, I didn't success, It tells Failure authentication because of the wrong password, because I enter my account password which I entered when I installed the system, Now I want to know how to solve this ISSUE, how to get the root password or how to reset It
I have to recover / reset root password. I do not have the 5.3 cd, can I boot with the CentOS-5.6-i386-LiveCD.iso [URL] and follow the recovery procedure outlined below [URL]
I have forgotten my root password for MySQL, what can I do to recover it, I've found a few guides but they don't work on the newer versions of Ubuntu.I am running on Ubuntu 10.04 server so MySQL is an upstart job so the methods I've seen with launching it without the access checks haven't worked for me
I have forgotton my root password for mysql. I followed some instructions on a website and now I am not sure what i have done?Basically, when I now try and start mysql I get a notification that i have converted the init script to an upstart. I dont know what this means.
Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start( utility, e.g. start mysql mysql start/running, process 20301.
how to reset a root password after inserting a live cd,ie . i need to reset my existing ubuntu root password, other options all i tried its gud , but need to knw hw to do this while having a live cd and resetting it !
I forgot my root password for mysql, and after some searching I found several solutions to fix it. But none of them seem to work.I tried this article http://ubuntu.flowconsult.at/en/mysq...root-password/ with starting mysql with the --skip-grant-tables option. The problem is that nothing happens, it just hangs.Also tried the the --init-file option, that one runs fine, at least it returned to the command line. But the sql query in the file to which it point doesnt seem to do anything. The password wasn't changed to the one I specified in the sql file.Any idea what could be going on here, and how I could fix it?
Can someone assist me with recovering/resetting the password for Root via Single User Mode in CentOS v5? I've modified the kernel line using Single, S, and 1 but it appears that these commands are being totally ignored as the server continues with the boot process and displays the GUI logon screen. The server in question is a VM box running on ESX v3.5 U4. The person that created this VM is no longer employed here and I've exhausted everything I know regarding Single User Mode.
Being able to reset the root password by booting into single usermode by editing grub. This is a MAJOR flaw. I know it makes no real difference against internet bourne attacks, but even so I must say I found it shocking. The only way I've found to stop this is to encrypt the entire HDD, so noone could get into single user mode without first knowing the encryption key/password.
I recently installed vsftpd on my server. I noticed that users on the machine can login into vsftpd with their username and password on the machine and go to their root dir "/home/username".Now, I want to give some people a vsftpd username and password so they can upload and download files and folders to their folder, but this folder has to be in the "/var/www/(username)" folder. I don't want them to be able to go to any other folder than their own folder like "/var", "/etc" or "/home" etc. Also I don't want them to be able to login on the machine as a user, through putty for example. They should only be allowed to acces their folder with vsftpd, nothing else.
My application is installed on root of RH enterprise 5 and is run via user on the same machine. This need ssh without password from the user.

How can i ssh from the user to the machine without password.
Im having a frustrating issue with my two machine cluster I setup using Conga. Everything was working great except now when lucci starts mysql the port (3306) is never opened to outside machines. I can do a "ps -ef | grep mysql" and see it running as well as login to mysql on the node it is running on - but an nmap of the machine does not show the 3306 port and I cannot login to mysql remotely and yes I turned off all iptables(iptables,ip6tables) and SElinux is disabled.What am I missing here? If I start mysql on my own (and it is using the same my.cnf as lucci is) it does show the port open and works perfect,t for some reason when lucci starts it, no dice
Having installed Debian 7 on an old machine from a Liinux Format Magazine DVD I was unable to log in as a specific user. I can login as root and use useradd etc but when I logout of root I still cannot login as a user and nor will the machine accept my root password. I have to shutdown and reboot to get back into root. I'm using O'Reilly's Linux Pocket Guide from 2004 for the commands. Could it be that things have changed?

I have configured a FTP (VSFTPD) Server in RHEL 5.6, which resulted me a default directory /var/ftp/pub. Even i have cerated another Directory /var/ftp/accounts. Where Accounts Directory is owned by user x in my server. I have a issue with this, It prompts me User and Password while accessing this ftp 192.168.5.20 in Linux Servers. But while i am trying this through a windows machine by ftp://192.168.5.20 it gets directly accessed without prompting me any User and Password.
I need to have FTP environment same like windows. where it must prompt me user name and password, and i must be able to upload and download data from my windows clients.
