Foreman,A Open Source Project

 1. What is Foreman?

Foreman is an open source project that helps system administrators manage servers throughout their lifecycle, from provisioning and configuration to orchestration and monitoring. Using Puppet, Chef, Salt, Ansible and Foreman’s smart proxy architecture, you can easily automate repetitive tasks, quickly deploy applications, and proactively manage change, both on-premise with VMs and bare-metal or in the cloud.
Foreman provide comprehensive, interaction facilities including a web frontend, CLI and RESTful API which enables you to build higher level business logic on top of a solid foundation.

The Foreman interface is very easy to use and user friendly.



As your organization grows, so does your workload — and the IT resources required to manage it. There is no “one-size-fits-all” system management solution, but a centralized, open source tool such as Foreman can help you manage your company’s IT assets by provisioning, maintaining, and updating hosts throughout the complete lifecycle.

Foreman becomes even more powerful when integrated with other open source projects and plugins, and I will discuss these in more detail below. To get started, however, let’s consider key functions of an effective system management tool.

Host provisioning is for deploying instances or virtual machines on bare-metal, on-premises, or a cloud provider’s data center.

Content management refers to publishing, promoting, and managing various versions of repositories and packages in the CDN and systems across the life cycle (i.e., development, testing, QA, and production).

Patch/errata management includes bug fixes and advisory or enhancement packages. An effective systems management tool should identify applicable errata regularly and patch registered systems promptly.

Subscription or license management enables the purchase, renewal, and extension of subscriptions through a systems management portal. This information should be updated frequently in the user account for each system.

Health monitoring and reporting enables real-time system checkups. This should include updates, errata, compliance, workload, and system performance metrics for registered hosts and running services.

Remote execution is for running arbitrary commands on hosts or groups of hosts to perform similar activities remotely. These commands can be customized; for example, to provision templates or partition tables.

Identity and policy lets you create different users and roles and manage various permission policies. This function should also support Kerberos and LDAP integration and authentication.

Alerts and notification audits administrator and user activities. This tool should instantly detect what changes are made in each node, when they are made, and where potential risk may exist.

Automation applies to repetitive tasks. A top systems management tool should help identify and automate these processes.

2. How to install Foreman?

Foreman can be installed on a Virtual Machine or on your bare metal.
For the initial setup, you must first open four mandatory ports 69 for TFTP, 80 for Http, 443 for Https UI access, 8140 for Puppet master and enable the Puppet, EPEL, and Foreman repositories. The following installation steps were performed on CentOS 7; however, other platforms that support Foreman installation include Fedora, Red Hat Enterprise Linux, Ubuntu, Oracle Linux, etc.

Step 1: Download Puppet, EPEL, and Foreman RPMs.

# yum -y install https://yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm
# yum -y install http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# yum -y install https://yum.theforeman

Step 2: Install and execute the Foreman installer RPM.
# yum -y install foreman-installer
# foreman-installer –help
# foreman-installer

Step 3: After installation, the installer with give you Foreman URL details, a default login user admin, and an auto-generated random password. Launch the Foreman https: URL on your browser and log in.



Successful installation of the Foreman tool using installer.



Login screen to Foreman GUI. Sign in here after installation to change your password.

Default password for Admin user is changeme.

For further information, you can refer to foreman documentation which includes information about foreman plugins and how to install them.

Need of Open Source ?

You have already got what is  Open Source  from previous blogs. The simple reason is that why to pay if we get is free. Lets take an example you spend lots of money to buy an windows genuine some of the people don’t buy the licence copy of it but they buy an creak (DOS) version of windows but they have some problem in it. Some what same not a completely different OS are freely available in market then why should we pay for it ? You get high quality of software and hardware also in open source. They are very powerful and smooth running no lags get while working.They also give full support to solve your problem.Think an example of google you search on google and you get the result of what you search if google say that I want money for every search results then ?you will pay for it ? That the need of  open source .

The End Is near: January 19, 2038 3:14:07 GMT

  Year 2038 problem The Year 2038 problem is an issue for computing and data storage situations in which time values are stored or calculated as a signed 32-bit integer, and the number is interpreted as the number of seconds since 00:00:00 UTC on 1 January 1970 (the epoch). Systems working on 32-bit cannot encode times after 03:14:07 UTC on 19 January 2038, analogous to the Y2K problem , in which 2-digit values representing the number of years since 1900 could not encode the year 2000 or later. Most 32-bit Unix like systems store and manipulate time in this Unix time format, so the year 2038 problem is sometimes referred to as the  Unix Millennium  Bug by association. What is Unix time? The  Unix epoch   time  is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds . Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but ‘epoch’ is often used as a synonym for ‘Unix time’. Many Unix systems store epoch dates as a signe

What is Dynamic Programming ?

  What actually dynamic programming is ? In computer science or mathematics,  dynamic programming  is a method for solving a complex problem by breaking it down into a collection of simpler subproblems, solving each of those subproblems just once, and storing their solutions. Also known as  dynamic   optimization . Dynamic programming is similar to divide and conquer only difference is that dynamic programming is used when there is overlapping subproblem property and in divide and conquer there is no overlapping subproblem property. example, fibonacci series. When to use dynamic programming ? Following two attributes suggests that a problem can be solved using  dynamic programming  : optimal substructure overlapping sub-problems. Ways to of using dynamic programming : Top-Down :  Firstly, Start solving the given problem by breaking it down. If you see that the problem has been solved already, then just return the saved answer. If it has not been solved, solve it and save the answer. Th
