I would like to install python3 and python3.4 in my office servers. There are 86 hosts and I am confused how I do that in the same time. In this time, I found my solution like this
pssh -h host_86.txt -i "yum install -y epel-release && yum install -y python34"
Is python3 included in python3.4 package automatically or separately? Is my solution right to do that? The OS is RHEL 7 and I found the yum package from here: How to install Python 3.4 on CentOS 6 & 7. Do I need to install python34-setuptools and easy_install-3.4?
I am junior system administrator and confused about how to handle 86 hosts a day.
