After receiving the SMS, there is one last step, select a support plan. Choose a support plan for your business or personal account.Compare plans and pricing examples You can change your plan at any time in the AWS Management Console.

Select the free basic support plan. Click Complete Registration and your Amazon Cloud account has been successfully registered. Isn't it simple?

Next, go to the AWS Management Console and apply for an Amazon EC2 cloud server.

Step 2: Apply for Amazon EC2 cloud server

Log in to the Amazon Cloud console homepage and click Services , click on calculate , continue to click under the calculation menu EC2 , go to the Amazon EC2 console page.

Step 2-1: Select the region where the EC2 server is located

In the upper right corner of the Amazon EC2 console page, you can select the region where the Amazon cloud server is located.

Which region should I choose for my cloud server? Which region has the fastest access speed? Amazon Cloud provides a speed comparison tool.

AWS Global Accelerator Speed Comparison Tool

You can use the AWS Global Accelerator Speed Comparison Tool to see how global accelerator download speeds across AWS Regions compare to direct Internet downloads. With this tool, you can use a browser to see the performance differences when transferring data using a global accelerator. You select the file size to download, and the tool downloads the file over HTTPS/TCP from an Application Load Balancer in different Regions to your browser. For each Region, you can see a direct comparison of download speeds.

To access the speed comparison tool, copy the following URL into your browser:https://speedtest.globalaccelerator.aws

For users in the Asia-Pacific region, the speeds in Tokyo, Osaka, Japan and Hong Kong, China are relatively faster.

Step 2-2: Create an instance

Next, we apply for an EC2 cloud server instance. Examples , click Examples , then click Launch a new instance.

After clicking the Launch New Instance button, you will be taken to the interface for creating an EC2 instance.

Step 2-3: Fill in the instance name and tags

exist Name and Label Fill in the name of the EC2 instance, just fill in one, for example: UZBOX.

Step 2-4: Select Application and Operating System

Next select Application and OS Image (Amazon Machine Image) Information
An AMI is a template that contains the software configuration (operating system, application server, and applications) needed to launch an instance. If you don't see what you need below, search or browse for an AMI.

We can see that the supported operating system images include Amazon Linux,macOS,Ubuntu, Windows, Red Hat, SUSE Linux,DebianIf you need to install other system images, you can click Browse other AMIs on the right.

For example: To install the CentOS system, click AWS Marketplace AMI (AWS and trusted third-party AMIs) or Community AMI, then search for Centos on the leftRefine the resultsInFree Trial, then in the search results, select the system image you want to install.

Community AMIs include all public AMIs, so anyone can publish an AMI and it will appear in this catalog. This catalog may also include paid products. When using community AMIs, the best practice is to make sure you know and trust the publisher before launching the AMI.

Test the installation and choose to install the RHEL-8.6.0_HVM-20220503-x86_64-2-Hourly2-GP2 system image, which is the Red Hat system in the quick start. The AMI ID is ami-011a403f2a9b2c39f.

Support free tier, you must choose a system image that supports the free package, otherwise you will be charged based on time. You must read this carefully before making a choice.

Step 2-5: Select instance type

Next is the choice Instance Type , in the Free Tier, the first year includes 750 hours of t2.micro (or t3.micro in regions where t2.micro is not available) on the Free Tier AMI each month.

The difference between t2.micro and t3.micro is that t2 has 1vCPU and 1GiB memory, while t3 has 2vCPU and 1GiB memory. From the CPU perspective, t3 has 1 more vCPU than t2.

When choosing an instance type that supports the free tier, it is recommended to choose t3.micro. Japan and South Korea in the Asia-Pacific region do not have t3.micro. Only t3.micro in Hong Kong, China supports the free tier.

The access speed of Hong Kong, China is slightly slower than that of Japan, but the difference is not too big. If you have requirements for CPU, you can choose Hong Kong, China, and if you have requirements for network speed, you can choose Japan.

Step 2-6: Create a key pair

After selecting the instance type, create a key pair. Click Create New Key Pair and enter the key pair name. The key pair type below is the default. For the private key file format, select it as needed. If you use PUTTY to connect, select the .ppk file format.

After the key pair is set, the key pair willAutomatically generate.pemFiles are automatically downloaded and saved on the local computer.downloadFolder, used for SSH connection.

Note: Please keep the SSH key safe. If the key is lost, you will not be able to connect to the server remotely.

NOTE: Red Hat systems use the .ppk key format!

Step 2-7: Network Setup

After the key pair is created Network Settings, the subnet information is default and does not need to be filled in. The system will automatically create a subnet IP.

Step 2-8: Configure the firewall

Firewall (Security Group)In the options, select an existing security group. Select the default security group in the common security group. This security group is a completely transparent firewall, and all traffic ports are open. If you want to customize the open ports, you can create a security group and select the open ports in the newly created security group.

Step 2-9: Configure storage

Configuration Storage Customers who qualify for the free tier can get up to 30GB of general purpose (SSD) or magnetic storage in the options. Change the hard disk size to 30GiB, gp2 by default, or change to gp3 as needed.

Note: The maximum hard disk size is 30 GiB. If it exceeds 30 GiB, the system will automatically charge you. The additional fees incurred each month will be automatically deducted from your credit card.

Comparing Amazon EBS volume types gp2 and gp3

gp3 is capable of providing up to 1000 MiB/s throughput, whereas gp2 provides a maximum throughput of 250 MiB/s.

After selecting the hard disk, click Launch the instance Click the button to start creating an EC2 cloud server.

At this point, the EC2 cloud server has been applied for. In the instance console, you can operate the instance, including SSH connection, restarting the instance, stopping the instance, terminating the instance, etc.

After applying for an EC2 cloud server, you also need to apply for an elastic IP to bind to the instance. Otherwise, every time you shut down and restart the server, the public IP address will change. This public IP address is automatically assigned by the EC2 cloud server. Unless your instance never fails or shuts down, the IP will become a new one after shutting down and restarting.

Public IP address
You cannot manually associate or disassociate a public IP address from an instance. The public IP address of an instance changes in the following situations:

• A stopped or hibernated instance receives a new public IP address when it is restarted.
• If the Elastic IP address associated with an instance is detached from the instance, it receives a new public IP address.

When a public IP address is no longer associated with an instance, it is returned to the public IP pool. You cannot restore the same public IP address for a stopped instance.

Elastic IP addresses
It is a best practice to use Elastic IP addresses. Elastic IP addresses are assigned to your account, not to instances. You can associate Elastic IP addresses with instances as needed.

All instances retain their associated Elastic IPs after they are stopped. AWS continues to bill for the Elastic IP addresses associated with the stopped instances.

Note: You cannot convert an automatically assigned dynamic public IP address to an Elastic IP address.

Step 2-10: Apply for an Elastic IP

To apply for an Elastic IP, in the EC2 console menu, click Network and Security The following Elastic IP , then click Allocate Elastic IP After entering the page for allocating elastic IP addresses, clickdistribute.

After the elastic IP address is allocated, you need to associate it with the instance. If it is not associated with the instance, the elastic IP address will be charged hourly. Click Associate this IP address.

On the Associate Elastic IP Address page, select the instance and private IP address, and click the Associate button.

The elastic IP has been associated successfully. Now, no matter how you restart or shut down the cloud server, the IP address will not change. However, you need to pay attention to one thing: if you delete the cloud server, you need to delete the corresponding elastic IP address in the elastic IP. Otherwise, the elastic IP will not be associated with the instance and will incur additional charges.

After applying for the EC2 cloud server, configure the cloud server. The Red Hat system configuration is basically the same as the Centos configuration.

Step 3:AWS Amazon Cloud Server Linux System Initial Configuration

After the Red Hat Enterprise Linux 8 virtual machine instance is enabled, it is still a blank system and all environments need to be reconfigured.

Step 3-1: Use SSH connection to Linux Examples

First, use the SSH connection tool Xshell to log in to the server.

Create a new session in Xshell and select the user authentication method Public Key , user name input ec2-user ,Note that you do not need to enter root here. In the User Key field, browse to import and select the SSH key you generated when you created the instance. After selecting the user key, click OK to connect through SSH.

You have successfully connected to the EC2 cloud server. Next, perform a simple server configuration.

Step 3-2:Modify server root password and remote login

The default account for AWS EC2 cloud server is ec2-user , which does not have permission for many operations. It needs to be changed to root Super administrator login.

Step 3-3: EC2 cloud server configuration LNMP environment

After applying for an EC2 server on Amazon Cloud, you still need to perform some simple environment configuration before installing the WordPress website. The following is how to configure the LNMP environment under Red Hat Enterprise Linux 8.
