Powershell AWS Automation Management (10)-Create a highly available WordPress blog (top)

It took 2 weeks for the beans to learn some of the core commands of AWS PowerShell intermittently, and then took 2 days to assemble the knowledge points together. Currently, in addition to the official documentation of the Quick Manuals and command Daquan basically there is not much PowerShell to manage the content of AWS, most of the command beans is a search and view help hard to try out, the following share out, if you have similar needs later can save some time.

Now demonstrate how to create a highly available WordPress blog on AWS with PowerShell scripts. This is a typical high-availability scenario for AWS.

Here are the basic requirements

2. The user elastic Load balancer URL,ELB forwards requests through DNS to the EC2 instance of any of these word press, which accesses the remote MARIADB RDS instance via port 3309;

4. MySQL achieves high availability through Multiple-az;

6. Web server enables load balancing and high availability through ELB;

8. According to the CPU or other load standard, ELB inside the cluster can automatically increase, delete EC2 instance;

10. The server created by auto Scaling must be automatically updated to the latest version;

12. All the pictures and videos involved in the blog must be saved on the S3 bucket, and the CDN acceleration via CloudFront, the blog's Media resource URL automatically redirects to the CDN address for parsing.

Now look at how PowerShell implements each of these features.

My basic idea

1. Create EC2-S3 role, which is assigned to EC2 virtual machines so that they automatically have access to S3 content after they are created.

2. Create a VPC Network

3. Create 2 subnets of a VPC, located in different AZ

4. Create an Internet gateway

5. Configure the routing table

6. Create and configure the EC2 security Group to ensure that 80 and 22 ports are available

7. Create a highly available MARIADB database

8. Configure the security Group for the database to ensure that port 3306 is available

9. Create a S3 Bucket and configure policy

10. Create CloudFront distribution points, bind S3 buckets

11. Preparing the WordPress configuration document

12. Preparing the configuration document for VirtualHost

13. Uploading the configuration document into the S3 bucket

14. Configure bash shell scripts, including Lamp,wordpress,aws,crontab and S3 synchronization, and more

15. Create a EC2 virtual machine, specify the bootstrap command created in 14 steps

16. Update DNS records, point to the virtual machine

17. Initializing the WordPress interface

18. Generate image file after confirmation is correct
    

19. Configure Elb

20. Update DNS records to ELB address

21. Configuring launch Configuration

22. Configure Auto Scaling

The next section looks at the specific scripting implementation.
