Теперь ваш Macbook pro действует, как главный узел или система управления.

Создание файла инвентаризации хостов

Ansible должен знать, к каким сервера подключиться, и затем управлять этими блоками. Вам нужно определить или создать перечень файлов хоста Ansible. Файл содержит список, параметры и группы для ваших серверов. Его местоположение по умолчанию — /usr/local/etc/ansible/hosts в MacOS X. Вы можете отредактировать файл /usr/local/etc/ansible/hosts или создать файл

Вот пример моего файла:

Сохраните изменения и закройте файл. Убедитесь, что вы установили ключи ssh в серверах box1 и 192.168.2.15. Если у вас нет ключа ssh на MacOS X, сгенерируйте ключ ssh на главном узле (MacOS X):

Установите ssh ключ:

Примеры возможных выводов данных:

Вы можете установить ANSIBLE_HOSTS для определения вашего файла

Установка Ansible в Mac OS

Установка с помощью Homebrew

Если у вас уже установлен Homebrew то достаточно сделать следующее:

Если вы хотели бы использовать Python и pip для установки, прочтите далее…

Нативная установка через Python:

Ansible использует Python и к счастью Python всегда устанавливается на новых версиях Mac OS.

• Установим Xcode
• sudo easy_install pip
• sudo pip install ansible —quiet

Далее, если вы хотите обновить Ansible позже, нужно будет выполнить:

• sudo pip install ansible —upgrade

Нативная установка через Python — с подробностями:

Убедитесь что Xcode у вас установлен

Некоторые зависимости Ansible должны быть скомпилированы, соответственно вам необходимы средства разработчиков Xcode.

Вы можете проверить наличие установленных средств разработчика используя команду:

(До OSX Mavericks, вам необходимо проверять наличие пакета «com.apple.pkg.DeveloperToolsCLI»)

Если утилита не установлена, вы увидите следующее сообщение:

В этом случае вам необходимо установить Xcode отсюда.

Если утилита установлена, вы увидите следующее:

Установите pip

pip это менеджер пакетов для Python. Он по умолчанию не установлен в OSX, но вы можете использовать и другие менеджеры пакетов Python, выполните easy_install для установки:

Установка Ansible

Обновление Ansible

С выходом новых версий Ansible вы можете легко обновится до новой версии:

How to install Ansible on Mac OS X

Written by Percy Grunwald

The two best methods for installing Ansible on Mac OS X are:

1. Using Homebrew (best for beginners)
2. Using Python pip (best for advanced users)

The official documentation states that their preferred method for installing Ansible on Mac OS X is using Python pip . I also agree that this is the best way to install Ansible and this is how I do it on my machine, however I think installing it by using Homebrew is probably the best way for beginners.

The main difference between the two methods is that using pip will give you more control over the Python version Ansible uses as well as any Python packages that Ansible depends on. This is especially useful if you’re using a version manager like asdf , which I highly recommend.

How to install Ansible on Mac OS X using Homebrew

First, ensure that you have Homebrew installed. Homebrew is a package manager for Mac OS X that allows you to install many packages useful for web/software development.

Installing Ansible on Mac OS X with Homebrew is as simple as running brew install ansible in Terminal (or your preferred terminal application):

After the installation has finished, you can confirm that Ansible has installed correctly by running ansible —version :

If ansible —version runs successfully, congratulations! You now have Ansible’s power at your fingertips and you’re ready to start managing your servers.

How to install Ansible on Mac OS X using Python pip

Confirm that pip is installed and upgrade it to the latest version

First, ensure that Python pip is installed on your system. You can check if pip is in your PATH by running which pip . If pip is found, run pip —version to confirm that everything is working as expected:

I use asdf to manage the Python versions on my system (and I suggest you do too). pip is automatically installed along with asdf Python installations.

If pip isn’t on your system and you’re using the default Python version on your system, you can usually install pip by running sudo easy_install pip .

I suggest running pip install —upgrade pip to update pip to the latest version before installing Ansible:

Install Ansible

Assuming pip is installed and working, installing Ansible is as simple as running pip install ansible :

Confirm that ansible is in your path and that it runs as expected:

If ansible —version runs successfully, congratulations! You now have Ansible’s power at your fingertips and you’re ready to start managing your servers.

Install Ansible on Mac OSX

Brew Install

If you already have Homebrew installed, then it is as simple as:

If you prefer to use Python and pip for the install, then read on.

Native Python Install — Summary:

Ansible uses Python and fortunately Python is already installed on modern versions of OSX.

• Install Xcode
• sudo easy_install pip
• sudo pip install ansible —quiet

Then, if you would like to update Ansible later, just do:

• sudo pip install ansible —upgrade

Native Python Install — Full explanation:

Ensure Xcode is installed first

Some of Ansible’s dependencies need to be compiled, so you’ll need the developer tools that come with Xcode.

You can check if you already have the developer tools by running this:

(note: Before OSX Mavericks, the package to check for was «com.apple.pkg.DeveloperToolsCLI»)

If the tools are not installed, you will see this output:

In that case, download and install Xcode from here.

If the tools are installed, you should see output similar to this:

Install pip

pip is Python’s package manager. It isn’t installed on OSX by default, but you can use Python’s other package manager easy_install to install it:

Install Ansible

Upgrade Ansible

When a new release of Ansible comes out, you can easily upgrade to the new version like this:

Setting up a Mac using Ansible

This Blog has been moved from Medium to blogs.tensult.com . All the latest content will be available there. Subscribe to our newsletter to stay updated.

In this blog entry, I want to share a step by step guide in using Ansible to set up a MacBook with the required Applications.

Using Ansible Playbooks we can easily configure the applications we want installed on our local system. The existing code can be modified so as to cater to each individual’s needs.

First, we’ll take a basic look at Ansible. Ansible is an open-source IT automation engine used for infrastructure automation. It enables us to reduce time and risk associated with making changes to the environment. We take something we want to change and put it into a script which then codifies the change we want to make. Ansible playbooks are written in YAML where key value pairs are denoted by a colon followed by a space. Ansible can work with one or multiple systems at the same time in your infrastructure. In order to work with multiple servers, Ansible needs to establish connection with the multiple servers. This is done using SSH in Linux and Powershell Remoting in Windows. This makes Ansible agentless (no need to install any additional software on target machine to work with Ansible).

Ansible Playbooks are Ansibles orchestration language where we define what we want Ansible to do. It is the set of instructions we want Ansible to carry out. It is a single YAML file which defines a set of activities or tasks to be run on the hosts. Tasks can vary from executing a command, running a script, installing a package, shutdown/restart etc. Each play contains a task. Tasks are executed in the order they are written one by one before moving on to the next. The goal of each task is to execute a module. Every task should have a name.

Ansible roles are nothing more than specific playbooks. Role allows us to take something which is common in all our playbooks and put them into a more specific playbook. The files under roles have to be in certain directory names. The ones that are not being used can be discarded. Some examples of directory names under roles are tasks, defaults, vars, files etc. You can read more about Ansible Roles here.

Getting started

Assuming you don’t have Ansible installed in your MacBook the following steps will explain how to install Ansible on your machine using Homebrew. If you have Ansible installed on your machine you can skip this part.

1. Install Homebrew by opening the Terminal and typing in the following command. Enter password when prompted. ( Homebrew simplifies the installation of software on the Mac OS X operating system. )

2. Install Git by copying the below commands into the terminal.

3. Install Ansible by using pip (Python package manager).

a. If pip isn’t already available on your computer then you can get pip by . running the following commands in the terminal.

b. Install Ansible with the following commands in the terminal.

sudo pip install ansible

Enter password whenever prompted.

Defining Ansible Playbooks

The approach I have taken is to define playbooks for different applications and included all these playbooks in the main playbook. Each playbook is called from the main playbook which downloads the application from the web and then executes the set of codes depending on the type of file downloaded using roles in Ansible.
