The tools described here are meant to empower dev teams to accomplish the same steps described elsewhere in these docs -- e.g. creating a CI Build Node with VMware -- but with healthy dose of efficiency at scale. Using infrastructure as code -- the creation of pre-defined scripts to be executed in pre-defined contexts -- is how we'll get there.
Ansible is a largely free and open source server configuration tool. It must be installed, along with Python, on the "control machine," which can be your local desktop if you like. From there, Ansible will require
SSH access to the target server -- in this case your Mac Cloud.
Once Ansible has gained access to the target environment via SSH, it can run provisioning scripts and the like to prepare your environment for whatever work needs to be done -- be it CI or anything else.
MacStadium maintains a handful of example scripts to get you started on the road to automating your deployments and more.
Roles are sets of tasks and files used to configure a host machine to perform a specific role (thus, the name).
Playbooks are mappings of Ansible Roles and the various host machines they are meant to configure for a given process.
Packer is a powerful, open-source tool that allows you to store a "live image" of a virtual machine, which can be cloned in seconds, rather than minutes or hours. It utilizes JSON to define the VM template, and because it is command-line-driven, it can easily be integrated into your build pipeline.
Packer is not a direct substitute for provisioning solutions. In fact, it is built to interface easily with Chef, Puppet and Ansible for the provisioning of the base VM image.
Virtual machine templates for your building pleasure.
Homebrew is a package manager that makes installing packages from the Mac terminal quick and easy. If you need to brush up on your skills with the Mac terminal, check out this tutorial.
Homebrew relies upon Xcode. So, you'll need to have Xcode installed. If you don't already have it, you can find it in the Apple AppStore.
You will be required to have some fluency with the Mac Terminal App which is situated in the Utilities Folder under the Applications Folder.
Installing Homebrew is straightforward; you’re only required to paste a single line of code in to your Terminal in order to install it.
Open your Terminal App
Copy and paste the following command, and then press ENTER
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install”
Hit the RETURN key when asked to do so
Follow the installation process on screen
When necessary, you can update Homebrew by simply using the following command in the Terminal App:
You can also enable auto completion for your brew commands by entering the command:
brew install bash-completion
Uninstalling Homebrew is just as simple as installing it.
Open the Terminal App
Copy and paste the following command and then press ENTER:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Text Editor (like Sublime Text 2) as you will need to edit some lines of code
Mac with High Sierra or above
First we need to stop the system installation of Apache from starting on boot:
sudo launchctl unload -w/System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null
We then have to stop the system installation of Apache, in case it is running in the background. We are going to install Apache using Homebrew, which will allow us to control the version of Apache:
sudo apachectl stop
If you haven't installed Apache before, expect a notification that it
could not find specified service.
Now we can proceed with the installation of Apache 2.4:
brew install httpd
Once the process finishes, you can check if your installation was successful. Be aware of the PATH used during installation of Homebrew-Cask, as you may have changed it:
which apachectl /usr/local/bin/apachectl
You can also check with:
This command will display the version of your server and its build.
At this stage, you should be ready to start Apache:
sudo apachectl start
Your website will be located under the IP address of your machine, for example http://22.214.171.124. Hopefully you’ll get a satisfying message saying “It Works!”
Now we have to make sure that Apache starts automatically on startup in case you decide to reboot your machine:
brew services start httpd
In the latest version of Brew, the default port used for Apache is 8080, you should change it to 80 using the Terminal App:
open -e /usr/local/etc/httpd/httpd.conf
Simply find the line that says
Listen 8080 and change it to
AllowOverride in your file, we will need to change it to:
AllowOverride controls what directives may be placed in .htaccess files.
It can be "All", "None", or any combination of the keywords:
AllowOverride FileInfoAuthConfig Limit
We also have to enable mod_rewrite
Search for the following line:
# LoadModule rewrite_module lib/httpd/modules/mod_rewrite.so
And simply remove the
# just before LoadModule.
Finally, we need to edit our ServerName which would look like this in your file:
# ServerName www.example.com:8080
Replace it with your IP Address or domain:
You can now restart apache:
sudo apachectl -k restart
PART 2 – PHP
First of all you need to decide which version of PHP you require ranging from 5.6 to 7.2, in this tutorial we’ll use 7.2 but installation of any other version would be much alike.
Install PHP 7.2 using brew.
brew install [email protected]
You can simply replace the
7.2 with another version according to your needs, it can be
5.6, 7.0, 7.1.
Once the installation finishes, you can begin editing files, beginning with
php.ini. It is the default configuration file for running applications.
You can decide to change the memory_limit, upload_max_filesize or max_execution_time. You can also activate safe mode.
Now you need to go back to your
httpd.conf file which we edited during the Apache installation process and add a line which will connect PHP with Apache once again use:
open -e /usr/local/etc/httpd/httpd.conf
Add libphp somewhere below the last edit we made by uncommenting LoadModule:
LoadModule php7_module /usr/local/opt/[email protected]/lib/httpd/modules/libphp7.so
At your discretion, depending on the project you’re working on, you can also edit an option which will allow you to load index.php or index.html
<IfModule dir_module> DirectoryIndex index.html </IfModule>
And replace it with:
<IfModule dir_module> DirectoryIndex index.htmlindex.htm index.php </IfModule>
Now you can stop and start apache once again to validate the changes.
PART 3 – MYSQL
At last you can install mysql and the process is very straightforward. You can even use the Native Packages to run the whole installation process.
For this example, we will go through the process of installing it with Homebrew:
brew install mysql
Now you can load and start services:
brew services start mysql
It will tell you to secure your installation, run the following command:
Set a new root password, remove anonymous users and other options to limit access to localhost only.
You can now restart the MySQL server:
brew services restart mysql
You’re all set.
