1. Install Git version control and Golang

• Install Git:

$ sudo yum install git -y
$ git --version

• Install Golang:

$ wget https://go.dev/dl/go1.23.4.linux-amd64.tar.gz
$ sudo tar -C /usr/local -xzf go1.23.4.linux-amd64.tar.gz
$ export PATH=$PATH:/usr/local/go/bin
$ go version

2. Clone the repository

• Clone the Blog application repository, or you can use your personal repository.

$ git clone https://github.com/minhnghia2k3/workshop-01.git

3. Export environment variables

Add the required environment variables for the application:

$ vi ~/.bashrc
export DATABASE_URL="admin:Admin123@tcp(<YOUR_DB_ENDPOINT>:3306)/blog_db"
export AWS_REGION="ap-southeast-1"
export S3_BUCKET_NAME="minhnghia2k3-blog-s3-bucket"

$ source ~/.bashrc

4. Run the application

$ ls
$ cd workshop-01
$ go build -o ./bin/main .
$ ./bin/main

• If successful, the server will open on port :3000.

5. Test Deployment and Functionality

• Access the EC2 domain, e.g., http://ec2-13-250-114-245.ap-southeast-1.compute.amazonaws.com:3000/
• Test blog creation:
• Test blog editing:
• Test blog deletion.

6. Check Storage in MySQL and S3 Bucket

From the EC2 SSH terminal:

1. Check MySQL:

$ mysql -h mysql-golang-db.c1a20mqwgeb9.ap-southeast-1.rds.amazonaws.com -P 3306 -u admin -pAdmin123
$ USE blog_db;
$ SELECT * FROM articles;

2. Check the Bucket:

• In the uploads/ folder, you can see that the application successfully stored the file to the S3 bucket.
