Managing & Configuring YUM [Centos 6.0]

Yum Configuration


 Hi Friends, we all have faced problems while configuring yum in RedHat, Fedora and Centos. Please find the below mention steps to use all the RPM packages come along with your distribution. Yum configuration will allow you to use them with proper dependency resolution.

To configure yum you must have two packages,
1. yum
2. createrepo

To obtain the same do the below mention just after you have mounted you disk.

There could be two conditions

a.) You have the distribution disk i.e. DVD. Please follow the below mention instructions to manage the same.
Your system mush have the greater or equal space of DVD.
# df -ah
User the partition which has the space and create a directory. In my case /mnt has the space.# mount /dev/dvdwriter /mnt
# cd /mnt/Packages/
# rpm -ivh yum-* --nodeps –force
# rpm -ivh vsftps* -y
# rpm -ivh createrepo* --nodeps --force
# cp -rpvf /mnt/* /var/ftp/pub
It will create the dump on /var/ftp/pub now we need to unmount the disk.
# umount /mnt
b.) You have an iso of you distribution. In that condition you need to mount it with loop so,
cd to iso location
It will mount the ISO to /mnt#mount -o loop rhel.iso /mnt
# cd /mnt/Packages/
# rpm -ivh yum-* --nodeps –force
# rpm -ivh vsftps* -y
# rpm -ivh createrepo* --nodeps --force
Copy packages folder to /var/ftp/pub
# cp -rpvh /mnt/Packages/* /var/ftp/pub


Now you have the dump of your distribution and you are ready to configure yum. To configure the same you must be aware of your hostname. Run the following command to know your hostname,

# hostname
CentOs

Now you have your host name create directories at /var/ftp/pub i.e. Server and VT by following command,

#mkdir -p Server; mkdir -p VT


You are ready to configure your Server and VT repos. Run the following command in order to generate the repos,

# createrepo -v Server ; createrepo -v VT

It will create the directory structure like /var/ftp/pub/Server/repodata & /var/ftp/pub/VT/repodata and a file repomd.xml under each. Configuration of yum is just a step ahead. Search a file like *debuginfo.repo* under /etc/yum/yum.repos.d/. Keep a copy of it for disaster and rename the same with a different command name,

# cp -rf *debuginfo.repo* `hostname`.repo

Edit the hostname.repo using your editor. I will you vim and will comment all the lines that are UN-commented and write new lines on it.# vim `hostname`.repo

#[debug]
#name=CentOS-6 - Debuginfo
#baseurl=http://debuginfo.centos.org/6/$basearch/
#gpgcheck=1
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-6
#enabled=0
#

[Server]
name=CentOs
baseurl=file:///var/ftp/pub/Server/
gpgcheck=0


[VT]
name=CentOs
baseurl=file:///var/ftp/pub/VT/
gpgcheck=0

Run yum clean all and you are done.

Thanks

Hubot and Hipchat

Many of us have struggle with concept of L1, and L2 support and maintenance which can be very expensive and transitioning is a living hell. What we wish is the ability for both of them to work together and make a smooth transition. So I have started to think it would be cool to make this happen for a organization which runs 1200+ servers and have teams to support product and infra both. The Idea was to start with collaboration between teams which can be extended to request and support basis. To extend it further we discovered  that product team works for 24x7 and infra team is 18x7. Now it is important to design it in a way that product team can manage it 24x7 with minimum and no help from infra team(L2).  Solution: Solution was to use a collaboration tool which supports API for our tools to maintain alert level. For that please refer my previous blog describing configuration of Icinga and Hipchat. Next logical step is to configure hipchat to support robot system ...

Read a File line by line in Shell

I've used a few techniques for this kind of reading but gets failed until I've read this fine blog . http://www.bashguru.com/2010/05/how-to-read-file-line-by-line-in-shell.html this helps a lot and i have developed a trick for me. Refer to the following example to examine the script : #!/bin/bash #SCRIPT: method2.sh #PURPOSE: Process a file line by line with redirected while-read loop . FILENAME=$1 count=0 while read LINE do let count++ echo "$count $LINE" done < $FILENAME echo -e "\nTotal $count Lines read" I have passed the file in the end of the loop so i didn't need  to use pipe that is why i process the file in fastest manner and gives  the required output in a quick manner. However i can use one more thing the File Descriptors. The File Descriptors are similar to the normal file pointers however in  more analogue way.If you have used C then you will have familier with the  the default file openers in C "st...
