Yum Update all my nodes at a time

Chef Infra (archive)

Hi,

I’m Prash, from india . I’m still new to Chef. So, let say that I have 5 nodes and I want to yum update all the nodes from the workstation, Can I do it, Is there any cookbooks to perform this process?

Thank you

Yes, there is a YUM cookbook available (a few infact). I would run the following command from the Chef-DK

knife supermarket search yum

Which will output the following data:

yum:
cookbook:             https://supermarket.chef.io/api/v1/cookbooks/yum
cookbook_description: Configures various yum components on Red Hat-like systems
cookbook_maintainer:  chef
cookbook_name:        yum
yum-centos:
cookbook:             https://supermarket.chef.io/api/v1/cookbooks/yum-centos
cookbook_description: Installs and configures the Centos Yum repositories
cookbook_maintainer:  chef
cookbook_name:        yum-centos
yum-cron:
cookbook:             https://supermarket.chef.io/api/v1/cookbooks/yum-cron
cookbook_description: Installs/Configures yum-cron
cookbook_maintainer:  osuosl
cookbook_name:        yum-cron
yum-epel:
cookbook:             https://supermarket.chef.io/api/v1/cookbooks/yum-epel
cookbook_description: Installs and configures the EPEL Yum repository
cookbook_maintainer:  chef
cookbook_name:        yum-epel
yum-fedora:
cookbook:             https://supermarket.chef.io/api/v1/cookbooks/yum-fedora
cookbook_description: Installs and configures the Fedora Yum repositories
cookbook_maintainer:  chef
cookbook_name:        yum-fedora

You can then install the cookbook using the following:

knife supermarket install <cookbook name>

…and have a play around to see if it suits your needs. If it does not, writing a custom cookbook with the following could be the simple answer you are looking for.

execute 'yum_update_upgrade' do
command 'sudo yum update && sudo yum upgrade'
end

i TRIED BY REMOVING SUDO IN THE COMMAND SO IT THIS ERROR CAN YOU PLEASE HELP ME IN SLOVING THIS…

Just add a -y so yum won’t try to be interactive and will assume yes to all questions. And if chef is run as root, there’s indeed no need for sudo.

6

Prash,

you could just use knife to accomplish this task as well:

with password and all specific platform i.e linux or whatever accepts ssh
connections:
knife ssh -x -p ‘platform:<platform_type>’ ‘sudo yum
update -y’ -C 5`

if no password is known
knife ssh -x --i ‘platform:<platform_type>’
‘sudo yum update -y’ -C 5`

7

can you please explain me the above commands with an example / may i know -C 5 is for?

8

-C is for count, how many nodes at a time you want to run this command on
simultaneously

9

with out bootstrapping a node with cookbook how can this be done by knife utility?
