Question: The Puppet server package is already installed on puppet master i.e jump server and the Puppet agent package is already installed on all App Servers. However, you may need to start the required services on all of these servers.
Configure autosign configuration on the Puppet master i.e jump server (by creating an autosign.conf in the puppet configuration directory) and assign the certificates for master node as well as for the all agent nodes. Use the respective host's FDQN to assign the certificates.
Use alias puppet (dns_alt_names) for master node and add its entry in /etc/hosts config file on master i.e Jump Server as well as on the all agent nodes i.e App Servers.
Notes: :- Please make sure to run the puppet agent test using sudo on agent nodes, otherwise you can face certificate issues. In that case you will have to clean the certificates first and then you will be able to run the puppet agent test.
:- Before clicking on the Check button please make sure to verify puppet server and puppet agent services are up and running on the respective servers, also please make sure to run puppet agent test to apply/test the changes manually first.
:- Please note that once lab is loaded, the puppet server service should start automatically on puppet master server, however it can take upto 2-3 minutes to start.
Solution:
In jump server at first edit the hosts file
vi /etc/hosts
Add puppet with the jump server
172.16.238.3 jump_host.stratos.xfusioncorp.com jump_host puppet
Then ping it
ping puppet
Then create an austosign.conf
vi /etc/puppetlabs/puppet/autosign.conf
jump_host.stratos.xfusioncorp.com
stapp01.stratos.xfusioncorp.com
stapp02.stratos.xfusioncorp.com
stapp03.stratos.xfusioncorp.com
Then restart puppet server
systemctl restart puppetserver
systemctl status puppetserver
Finally sign the certificates
puppetserver ca sign --all
Next, go to all appservers (stapp01,stapp02, stapp03)
Then in all appservers edit the hosts file
vi /etc/hosts
Add puppet with the jump server
172.16.238.3 jump_host.stratos.xfusioncorp.com jump_host puppet
Then ping it
ping puppet
Restart the puppet
systemctl restart puppet
systemctl status puppet
Validateby running puppet agent
puppet agent -tv
Then go to jump servers and run
puppetserver ca list --all
You can see the signed certificates of jump server, stapp01, stapp02, and stapp03
C is a high-level programming language that is widely used for developing system software, embedded systems, and applications. It was developed by Dennis Ritchie at Bell Labs in the early 1970s as an extension of the B programming language. C has become a popular language due to its efficiency, simplicity, and flexibility.
ReplyDeleteSome of the key features of C language are:
Portability: C is a portable language, which means that programs written in C can be compiled and executed on different platforms with little or no modification.
Low-level programming: C allows direct manipulation of memory, making it suitable for writing system-level software such as operating systems, device drivers, and compilers.
Flexibility: C provides a wide range of data types, control structures, and functions, which makes it suitable for a variety of applications.
Efficiency: C is a compiled language, which means that programs written in C can execute much faster than interpreted languages.
Some of the concepts that you will learn while studying C language include:
Data types: C provides a variety of data types such as int, float, double, char, and pointers.
Operators: C provides various operators such as arithmetic, relational, logical, bitwise, and conditional operators.
Control structures: C provides control structures such as if-else statements, switch statements, while loops, for loops, and do-while loops.
Arrays and Strings: C provides the ability to declare, initialise, and use arrays and strings.
Functions: C allows defining and calling functions, which can be used to modularize the code.
Pointers: C provides the ability to declare, initialise, and use pointers, which are used to manipulate memory directly.
Structures and Unions: C provides the ability to define and use structures and unions, which can be used to group related data.
File handling: C provides the ability to read and write data to files, which is useful for handling large amounts of data.
