Simply awesome

[@JaiBee007]

Great work Saurabhn n team. Quick Q - With Java JDK, you simply downloaded the module from puppet-labs and the agents possibly retrieved the same from the Server. With Tomcat, you downloaded the module from puppet-labs and then also had to specify the download location to the binary. A bit confusing to me, can you or anyone clarify. I do not want to my nodes exposed or download stuff from the internet and would not make sense from security / bandwidth / performance perspective if you have 10s of 100s of nodes and each one having to go out individually. Thanks

[@ramoneshere]

[@HardwiredNerd]

Let me clear my terminal.

[@sureshk1133]

Team , thanks for the clear presentation. I suppose manifests has to be created on master via text editor , but can we call the agent to check its catalog and update accordingly , from the console itself ?

[@edurekaIN]

Hey Suresh, Can ssh to agent and run the test catalog just to make sure there are no errors. Once you get the test catalog verified, then you can make sure it runs on all agents. Hope this helps. Cheers!

[@ramasubbareddy6147]

hi, firstly I would say that the tutorial is very good to install puppet master and agent once the above step is done and establishing the connection between puppet master and agent is very good after that configuring or deploying apache tomcat is very good in puppet agent only the query is that where the localhost has run in your web site, whether it is ran in puppet master or puppet agent or in your local machine that is not either puppet master or puppet agent

[@edurekaIN]

+Rama Subba Reddy, thanks for checking out our tutorial! We're glad you liked it. The localhost should be run on puppet agent machine. You can also check the page from localmachine giving the right url of agent and port. Hope this helps. Cheers!

[@AJ-hp3te]

his voice is awesome

[@edurekaIN]

Hey A J, thank you for watching our video. Do subscribe and stay tuned for more awesome updates on our channel. Cheers :)

[@raghuc8096]

Thanks excellent presentation. I have installed ubuntu, can you tell how to write Site.pp file ( Install Javajdk and install Apache tomcat ) .

[@edurekaIN]

+Raghu P, thanks for checking out the tutorial! For Ubuntu also you can edit the site.pp file in the same manner like we have done in CentOS. Manifests are basically puppet programs so It remains same irrespective of the Operating System. Hope this helps. Cheers!

[@sureshk1133]

Do we have an inbuilt option to install puppet agents in bulk?

[@edurekaIN]

Hey Suresh, thanks for checking out our tutorial! We suspect that you have accidentally downloaded and installed the client package, which does not include that particular binary. The server .deb files are named in the format chef-server_version_arch.deb. Hope this helps. Cheers!

[@nishantmnnit2k9]

It would be very helpful if you can provide the explanation to every step, as in why do we need to write that specific command, its purpose, explanation of syntax, etc.

[@edurekaIN]

For more reference you can refer to our blog on the same. The link for the blog is www.edureka.co/blog/install-puppet/

[@hunkmujeeb]

what if i am using rhel 6.5 or 7 which should i copy as repository ?

[@edurekaIN]

Hey Mujeeb, thanks for checking out our tutorial! Here you go. Enterprise Linux 7: sudo rpm -ivh yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm Enterprise Linux 6: sudo rpm -ivh yum.puppetlabs.com/puppetlabs-release-el-6.noarch.rpm Hope this helps. Cheers!

[@akshaykeni7548]

Hi, When i run puppet agent -t command in the puppet agent terminal. it is taking too much time and then i get this below error err: Could not request certificate: execution expired Exiting; failed to retrieve certificate and waitforcert is disabled. Can you please suggest me with the same? And also when i run puppet cert list in the puppetmaster terminal, i don get to see anything.

[@edurekaIN]

Hey Akshay, thanks for checking out our tutorial. So puppet agent will be sending a certificate to puppet master and when the puppet master signs the certificate , then only you will be able to execute any modules/manifests. Please re-check your configuration again and also check the firewall, in case if the port 8140 is blocked. You will be able to resolve once either of the mentioned are fixed. Hope this helps. Cheers!

[@anuragtripathi01]

How to configure puppet agent on windows and how to execute first manifest on it?

[@edurekaIN]

Hey Anurag, thanks for checking out our tutorial! Please go through the link to learn about docs.puppet.com/puppet/4.9/services_commands_windows.html for puppet installation on windows. Hope this helps. Cheers!

[@atanudebnath9173]

I have fixed the issue. by sync time between master and agent.

[@edurekaIN]

Hey Atanu, thanks for checking out our tutorial. We're glad your issue has been solved. Do subscribe to our channel to stay posted on upcoming tutorials. Cheers!

[@prbvarma]

service iptables save is not working in centos 7 how can i save the tables?

[@edurekaIN]

+prb varma, thanks for checking out our tutorial. Yes iptables concept exists only in the centOS 6. In the newer version of centos, they have changed to firewall, sudo service firewalld stop will work in centos. Hope this helps. Cheers!

[@McMurchie]

Good man, this was the same problem I was having. I get Failed to stop firewall.service: Unit firewall.service not loaded. I take it, this isn't a problem?

[@navyasriveluri]

in order for this to work we have to use three more commands... and then it'll work... at least t worked for me... try the following commands 1) Systemctl disable firewalld 2) yum install iptables-services (i had to install in my system, if you already have it then you may skip this step) 3) systemctl enable iptables 4) service iptables save it should work..

[@navyasriveluri]

17:12 i'm kind of facing an issue...

[@edurekaIN]

Hey Navyasri, what issue are you facing? You can ask us here or raise it to our support team since you are a registered learner. Cheers:)

[@rohan_dsouza]

Hey, thanks for the video tutorial. Just wanted to confirm, if I have to install nginx on all my puppet agents, what all changes would I need to do that are not mentioned in the video. On Puppet Master, I did the following: # puppet module install puppetlabs-nginx Notice: Preparing to install into /etc/puppet/modules ... Notice: Downloading from forgeapi.puppetlabs.com ... Notice: Installing -- do not interrupt ... /etc/puppet/modules └─┬ puppetlabs-nginx (v99.99.99) └── puppetlabs-stdlib (v4.16.0) Could you please tell me what changes have to be done in the sites.pp file such that nginx is installed on the puppet agent using yum.

[@edurekaIN]

Hey Rohan, thanks for checking out our tutorial! Here's the solution to your query: Once you have downloaded the Nginx module, just declare the Nginx class in the site.pp file present in the Puppet manifests like this: class { 'nginx': } Hope this helps. Cheers!

[@RahulRaj-xd3jl]

When I am typing puppet agent - t command my system is hanging please any one help me to sort out this problem

[@edurekaIN]

Hey Rahul, If you're going to dump NoSQL (because it may be wrong for your project), you could use any back-end and get similar performance. Hope this helps!

[@udayashangar1037]
