Ansible Tower (formerly ‘AWX') is a web-based solution that makes Ansible even more easy to use for IT teams of all kinds. It's designed to be the hub for all of your automation tasks.
Main advantage of PHP 7.x is that it will load your web application faster and will consume less server's resources like CPU and RAM. By default, PHP 5.4 is available in CentOS 7 and RHEL 7 yum repositories. In this article we will demonstrate how to install latest version of PHP on CentOS 7 and RHEL 7 Servers. Welcome to today's guide on how to install PHP 7.4 on CentOS 8 / RHEL 8 Linux system. The PHP Version 7.4.0 has been released for the developers, and users interested in running it in production. The official release date for GA was November 28, 2019. Follow the steps below to Install PHP 7.4 on CentOS 8 / RHEL 8 Linux system. Containers have revolutionized Applications deployment and massive scalability of microservices. Docker was a game-changer, simplifying the process of running and managing applications in containers. This article will guide you through the installation of Docker on RHEL 7. For CentOS 7, check Docker Installation on CentOS 7. By default the CentOS 7 official software package repositories have PHP 5.4, which has reached the end of life and no longer actively maintained by the developers.To keep up with the latest features and security updates, you need a newer (probably the latest) version of PHP on your CentOS 7 system. # yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine 2. To install the latest version of the Docker Engine you need to set up the Docker repository and install the yum-utils package to enable Docker stable repository on the system.
Tower allows you to control access to who can access what, even allowing sharing of SSH credentials without someone being able to transfer those credentials. Inventory can be graphically managed or synced with a wide variety of cloud sources. It logs all of your jobs, integrates well with LDAP, and has an amazing browsable REST API. Command line tools are available for easy integration with Jenkins as well. Provisioning callbacks provide great support for autoscaling topologies.
AWX provides a web-based user interface, REST API, and task engine built on top of Ansible. It is the upstream project for Tower, a commercial derivative of AWX.
Prerequisites
Before you can run a deployment, you'll need the following installed in your local environment:
- Ansible Requires Version 2.8+
- Docker
- A recent version
- docker Python module
- This is incompatible with
docker-py. If you have previously installeddocker-py, please uninstall it. - We use this module instead of
docker-pybecause it is what thedocker-composePython module requires.
- This is incompatible with
- Git Requires Version 1.8.4+
- Python 3.6+
- Node 10.x LTS version
- This is only required if you're building your own container images with
use_container_for_build=false
- This is only required if you're building your own container images with
- NPM 6.x LTS
- This is only required if you're building your own container images with
use_container_for_build=false
- This is only required if you're building your own container images with
System Requirements
The system that runs the AWX service will need to satisfy the following requirements
- At least 4GB of memory
- At least 2 cpu cores
- At least 20GB of space
- Running Docker, Openshift, or Kubernetes
- If you choose to use an external PostgreSQL database, please note that the minimum version is 10+.
