Using Ansible to Install R and Workbench on RedHat/ Centos/ Rocky Linux Servers
IMPORTANT: Ansible installation and support is outside the scope of Posit Support. The following instructions are for guidance only, and they should be modified based on your OS/Linux environment and your specific needs. For more information on Ansible, see the resource here; https://docs.ansible.com/ansible/latest/.
Ansible is an open-source automation tool, or platform, used for IT tasks such as configuration management, installations, and application deployment.
Benefits of using Ansible:
- Free: Ansible is an open-source tool.
- Simple setup: No special coding skills are necessary to use Ansible’s playbooks.
- Powerful: Ansible lets you model even highly complex IT workflows.
- Agentless: You don’t need to install any other software or firewall ports on the client systems you want to automate.
- Efficient: Because you don’t need to install any extra software, there’s more room for application resources on your server.
- Install, and upgrade Posit products
- Start and stop services.
- Perform a wide variety of configuration tasks.
- Implement a security policy.
Using Ansible to install WorkBench
- RPM-based Linux Server from Ansible will be run ("the Ansible server")
- Inventory file of the target servers on the Ansible server.
- Download and install EPEL repository
- Install Ansible packages from the EPEL repository
- Create a playbook to deploy the product, typically titled
Follow the steps below to install Ansible on RHEL/CentOS 8
Update /etc/hosts file with the hostname and IP details of your Ansible server and managed hosts in your setup.
# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
10.10.10.21 ansible ansible.example.com
10.10.10.25 host1 host1.example.com
10.10.10.26 host2 host2.example.com
Download and install the EPEL repository using your package manager of choice (RPM/YUM/DNF);
# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
# dnf -y install epel-release
# dnf -y install ansible
Validate that ansible is installed.
# ansible -–version
************** Done! Ansible is installed. *******************
Next, create an inventory file with the hosts you would like to deploy the product on.
# touch myhosts.txt && vi myhosts.txt
After that, create a playbook; you can use the template below as an example:
Note: The example below is based on the Rocky Linux distribution of Linux; please customize your code to fit your Linux distribution and environment.
- name: update server
- name: Install EPEL Repo
- name: Install dnf-plugins-core
# use this parameter for Rocky linux and comment out the next codeReady parameter.
#- name: Enable powertools
# path: "/etc/yum.repos.d/Rocky-PowerTools.repo"
# section: powertools
# option: enabled
# value: "1"
# mode: "0644"
# - Yum update cache
