yum setup on RHEL 6 and samba installation

Here are the quick steps:

mkdir -p  /var/OSimage/RHEL_6
 mount -o loop /ISO/rhel-server-6.4-x86_64-dvd.iso  /var/OSimage/RHEL_6

To make sure that the iso is mounted after each reboot make it permanent in the fstab file:

[root@RHEL-6 ~]# cat /etc/fstab

/ISO/rhel-server-6.4-x86_64-dvd.iso             /var/OSimage/RHEL_6 loop         defaults 0 0

Create a file:

vi /etc/yum.repos.d/rhel6.repo

[RHEL-6]
name=RedHat nterprise Linux 6
baseurl=file:///var/OSimage/RHEL_6
enabled=1
gpgcheck=0

save and exit

1 means enabled 0 means disabled. Here we are enabling the file:///var/OSimage/RHEL_6 as a yum repository.

Now run following two commands:

1. yum clean all

2. yum repolist

[root@RHEL-6 ~]# yum clean all

To test I installed samba - It will resolve the dependencies on ots own.

SSH Passwordless login

This is tested on RHEL-6

run the following command to generate the public key and copy it over to the system where you want to login without password.

[root@RHEL-6 .ssh]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
/root/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
ea:86:92:04:ac:35:21:e8:bf:9d:3c:72:26:f4:46:3a root@RHEL-6
The key's randomart image is:
+--[ RSA 2048]----+

[root@RHEL-6 .ssh]# ll

type in the following command now :

ssh-copy-id -i ~/.ssh/id_rsa.pub  rsangvik@cluster1

You would get the following message: And the  .ssh/authorized_keys is created automatically with th command

Now try logging into the machine, with "ssh 'rsangvik@cluster1'", and check in:

  .ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

[root@RHEL-6 .ssh]# ssh rsangvik@cluster1

YUM repository setup on ISO based - RHEL -5

Initially I created mkdir /var/repo/
mount -o loop /var/rhel5.iso /var/repo
cd /var/repo
createrepo .
and then ran createrepo on it. But would get the following error:
Directory must be writable.
To resolve that create a soft link
mkdir /var/repo/Server --> This is the path where I will dump my all RPM's from Server directory
ln -s /var/repo/Server/ /var/repo/Server
createrepo /var/repo/Server

Now......... Add following to the file

 cat /etc/yum.repos.d/iso.repo

[My ISO Repository]
name=test
baseurl=file:///var/repo/Server
enabled=1
gpgcheck=0

Now... Lets test:

[root@smtreeprd02 ~]# rpm -qa | grep -i telnet

[root@smtreeprd02 ~]# yum remove telnet-0.17-38.el5

mount DVD in RHEL 5

I was not able to find this on internet and on forums. But I knew I had one Linux box where I had done full installation and DVD would get mounted there. Hence ran ls -l /dev/dvd and found that it is soft linked to hdc. So did the following:

[root@smtreeprd05 ~]# ln -s /dev/hdc /dev/dvd
[root@smtreeprd05 ~]# ls -l /dev/dvd
lrwxrwxrwx 1 root root 8 Jun  4 01:22 /dev/dvd -> /dev/hdc
[root@smtreeprd05 ~]# mount /dev/dvd /mnt/

RHEL 5 Kickstart setup and installation

Below is the short process of how to setup the Kickstart server and create a Kickstart file for automated installation with HTTP style.

Set up web server Apache which is default on RHEL-5.
Create an iso with the dd command as shown below
mount the DVD

# mount /dev/dvd /mnt
# dd if=/dev/dvd of=/var/rhel5.iso
# mkdir /var/www/html/kick
# cd /var/www/html/kick
dump your DVD mounted files and directories with following way:

#  rsync -rv /mnt/* .

copy the anaconda.ks.cfg file from /root and modify as per your requirement. Here is the basic one just to get the things going - So this is simply just for reference - in case you forget OR set up the Kickstart after a while :-) in that case you may really need some notes to refer.

Example ks.cfg file:

# Kickstart file automatically generated by anaconda.

install
url --url http://192.168.60.130/kick
key --skip
lang en_US.UTF-8
langsupport --default=en_US.UTF-8 en_US.UTF-8

firewall --disabled

authconfig --enableshadow --enablemd5
timezone America/Phoenix
bootloader --location=mbr --append="rhgb quiet"
# The following is the partition information you requested
# Note that any partitions you deleted are not expressed
# here so unless you clear all partitions first, this is
# not guaranteed to work
clearpart --all --initlabel
