(2) ansible installation and deployment

Ansible installation and deployment is very simple, only rely on python and ssh, and these two dependencies are installed by default. Most of the environments I have come into contact with are centos and redhat environments, and there are also a few systems such as ubuntu and suse. However, I am familiar with installing ansible as a management node in the centos operating system.

1. Pip installation

The bottom layer of ansbile is also written on python, so you can install ansible through pip.

Step 1: install the python-pip and pythondevel packages

Shell > yum install python-pip python-devel-y

Step 2: check the installation environment

/ / make sure that development environment packages such as gcc glibc are installed on the server

Shell > yum install gcc glibc-devel zlib-devel rpm-build openssl-devel-y

/ / Update pip to the latest version

Shell > pip install-- upgrde pip

Step 3: install ansible

Shell > pip install ansible-- upgrade

Step 4: view the installed version of ansible

Shell > ansible-- version

Ansible 2.7.10

Note: the centos7.5 method may not be installed successfully because of the problem with the python version, when you pip, the new version of ansible will report that the python is too low.

If the system python version upgrade, then you will encounter a lot of problems, recommend 2 tools you can understand, Pyenv / Virtualenv multi-python environment extension management tools.

II. Yum installation

(1) add yum source and select Ali epel source

Shell > rpm-ivh https://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm centos7

Shell > rpm-ivh https://mirrors.aliyun.com/epel/epel-release-latest-6.noarch.rpm centos6

(2) yum installs ansible

Shell > yum-y install ansible

III. Apt-get installation

(1) add ansible source

Shell > apt-add-repository-y ppa:ansible/ansible

(2) install ansible

Shell > apt-get update

Shell > apt-get install-y ansible
