Creating VPC using Terraform and hosting WordPress web server and MySQL database

So let's get started !!

Step1 — Configure AWS in cmd line

Step 2 — Create a key pair for login into the EC2 instance

Step 3 — Create an instance with WordPress server and MySQL database server

in this instance, I have installed MySQL database using yum install.

Then I install WordPress .tar files using wget cmd and then unzip .tar files in /var/www/html folder

Then I change the mode of wp-content to read and execute to everyone and write for the owner as well using

cmd — chmod -R 755 wp-content

Then I change the owner of apache so that it can run on the apache server

Then I start httpd server

Then I launch MySQL database server

Step 4— Create a VPC(virtual private cloud)

# Creating a new VPC
*resource “aws_vpc” “task3_vpc” {
cidr_block = “192.168.0.0/16”
enable_dns_hostnames = true

tags = {
Name = “task3_vpc”
}
}*

Step 5— Then I created a public subnet for WordPress and a private subnet for MySQL database

Step 6— Create a security group for the private and public subnet

Step 7— Create a database subnet group in vpc basically it is a collection of different private subnets for your database

*# Creating Private Subnet for database
resource “aws_subnet” “private_subnet” {
vpc_id = aws_vpc.task3_vpc.id
cidr_block = “192.168.6.0/24”

tags = {
Name = “private_subnet”
}
}*

Step 8— Create an internet gateway for outside connection with the internet

resource “aws_internet_gateway” “public_gw” {
vpc_id = aws_vpc.task3_vpc.id

tags = {
Name = “public_facing_internet_gateway”
}
}

Step 9— Create a router table for your internet gateway it is a set of rules called routes for your IP to show the way or their destination

# Creating a route table to go to Internet Gateway
resource “aws_default_route_table” “gw_router” {
default_route_table_id = aws_vpc.task3_vpc.default_route_table_id

route {
cidr_block = “0.0.0.0/0”
gateway_id = aws_internet_gateway.public_gw.id
}

tags = {
Name = “default router table”
}
}

Step 10— Now associate or add your public subnet with route table

resource “aws_route_table_association” “associate_subnet” {
subnet_id = aws_subnet.public_subnet.id
route_table_id = aws_default_route_table.gw_router.id
}

Now you are almost done just run two cmd

1. terraform init

2. terraform apply

After successfully a apply just copy the public IP of your instance from aws running instances and paste it on google and you will see wp famous login page like this

Now enter the same details as you mentioned while launching my sql database and complete the installation and have fun with it in my case in writing a blog

Thank you !!
