  • Track hits per page
  • Track total hits
  • Track total unique visitors
  • Track IP, user agent, and timestamp information
  • View consolidated information with tables and graphs

Usage

Add this snippet to the page you want to track:

require_once('conn.php');
require_once('counter.php');

updateCounter("page name"); // Updates page hits
updateInfo(); // Updates hit info

Installation notes

Tested with PHP 5.4.16 and MySQL 5.1.72

  • Make sure you have PHP Data Objects (PDO) enabled.
  • Open up conn.php and add your database information where required.
  • Run install.php. A message will be displayed if the installation was successful.
  • Delete install.php.
  • Add relevant code to the page you wish to track.

For Deployment Automation through Ansible please follwo the below steps:

The first step is to install Ansible. This is easily accomplished by installing the PPA (Personal Package Archive), and installing the Ansible package with apt. First, add the PPA using the apt-add-repository command.

  • sudo apt-add-repository ppa:ansible/ansible Once that has finished, update the apt cache.
  • sudo apt-get update
  • sudo apt-get install ansible Create a new directory
  • mkdir ~/ansible-php Move into the new directory.
  • cd ~/ansible-php/
  • vi ansible.cfg Add in the hostfile configuration option with the value of hosts in the [defaults] group by copying the following into the ansible.cfg file. [defaults] hostfile = hosts
  • nano hosts Copy the below to add in a section for php, replacing your_server_ip with your server IP address and sammy with the sudo non-root user you created in the prerequisites on your PHP Droplet. [php] your_server_ip ansible_ssh_user=sammy
  • ansible php -m ping Output 111.111.111.111 | success >> { "changed": false, "ping": "pong" }
  • vi php.yml

  • hosts: php sudo: yes

AWS horizontal scaling using CloudFormation

Here you configure an auto scaling group with a minimum size of 2 and maximum size of 4, with a defined set of metrics and at what schedule (or granularity) the metrics will be collected.

my_group: Type: “AWS::AutoScaling::AutoScalingGroup” Properties: AvailabilityZones: Fn::GetAZs: “” LaunchConfigurationName: Ref: “LaunchConfig” MinSize: “2” MaxSize: “4” LoadBalancerNames: – Ref: “ElasticLoadBalancer” MetricsCollection: – Granularity: “1Minute” Metrics: – “GroupMinSize” – “GroupMaxSize”

Here is a simple construct for defining an instance.

SimpleConfig: Type: AWS::AutoScaling::LaunchConfiguration Properties: ImageId: my_ami SecurityGroups: – Ref: mySecurityGroup – myExistingEC2SecurityGroup InstanceType: m1.small

And here is a construct to define the metrics and thresholds for how the scaling group will grow.
