Tutorial: Deploy HAProxy Enterprise in an Amazon VPC Jump to heading #

During this procedure, you will deploy a single HAProxy Enterprise load balancer in an Amazon Virtual Private Cloud (VPC) to load balance traffic to web applications.

This design does not include redundancy at the load balancing tier, but is useful for non-production workloads or applications that do not require extra redundancy that you would get by deploying two HAProxy Enterprise load balancers.

Prerequisites Jump to heading #

Before getting started:

• Set up an AWS account if you have not already.
• Learn about common deployment patterns.

What you will accomplish Jump to heading #

In this tutorial, you will:

• Create an Amazon VPC with public and private subnets, and NAT gateways.
• Create the HAProxy Enterprise instance.
• Create an EC2 instance to act as a web server.
• Optionally, add a second HAProxy Enterprise instance and a Network Load Balancer.

This tutorial should take approximately 30 minutes.

Create a VPC Jump to heading #

The VPC will contain your load balancer on a public subnet, while your web servers will be on a private subnet accessible only through the load balancer.

To create the Amazon VPC:

1. Open the Amazon VPC console.

2. Click Create VPC.

3. On the Create VPC screen, choose the following values:

   Field	Description	Example value
   Resources to create	Whether to create additional resources such as subnets and availability zones with your VPC.	VPC and more
   Name tag	The name to attach to resources being created.	example
   IPv4 CIDR block	The IP range to assign to the VPC.	10.0.0.0/16
   IPv6 CIDR block	Whether to enable IPv6 addresses.	No IPv6 CIDR block
   Tenancy	Whether to use single-tenant (default) or dedicated hardware for your VPC.	Default
   Number of availability zones	Choose the number of availability zones for high availability.	2
   Number of public subnets	We will deploy the HAProxy Enterprise server into one public subnet so that internet traffic can access it.	2
   Number of private subnets	Create a private subnet for your web servers. Traffic will go through your load balancers to reach these servers.	2
   NAT gateway	Create a NAT gateway so that servers in the private subnet can reach the internet for software updates.	1 per AZ
   VPC endpoints	Whether to create an S3 Gateway.	None
   Enable DNS hostnames	Whether to enable DNS hostnames for your public IP addresses.	checked
   Enable DNS resolution	Whether to enable DNS resolution using the Amazon DNS server.	checked

   For more information about VPCs, review AWS’s Virtual Private Clouds documentation.

Launch the HAProxy Enterprise AMI Jump to heading #

Launch the HAProxy Enterprise AMI and connect to the instance.

Create a web servers security group Jump to heading #

Create a security group that will allow the HAProxy Enterprise load balancer to communicate with the web servers over ports 22 (SSH) and 80 (HTTP):

1. Open the Amazon EC2 console.

2. From the EC2 Dashboard, click Security Groups, then Create security group.

3. On the Create security group screen, set the following fields:

   Field	Description	Example value
   Security group name	The name to assign to the security group.	webservers-security-group
   Description	A description for the security group.	Security group rules for web servers
   VPC	Choose the VPC ID from the VPC you created earlier.	vpc-0146c0c368ac64143

4. Add the following inbound rules:

   Type	Source	Source value
   HTTP	Custom	Choose the security group you assigned to the load balancer
   SSH	Custom	Choose the security group you assigned to the load balancer

5. Click Create security group.

Launch a web server Jump to heading #

For example purposes, create a web server that handles web requests. We will configure HAProxy Enterprise to route traffic to it.

1. From the EC2 Dashboard, click Launch instance.

   Choose a server AMI, such as Amazon Linux.

2. Choose the SSH key pair used to connect to the EC2 instance.

3. Under Network settings, click Edit.

4. Set the following fields:

   Field	Description	Example value
   VPC	Select the VPC you created.	vpc-0146c0c368ac64143
   Subnet	Select one of the private subnets.	subnet-0700b54c5c1e471664
   Auto-assign public IP	Whether to assign a public IP address to this instance.	Disable
   Firewall	The web servers security group that you created.	Select existing security group, sg-0671c2f614fbf7d1e

5. Click Launch instance.

6. Connect to the web server via SSH. Because the web server is on the private subnet, you will need to connect to it via the HAProxy Enterprise server, which is on the public subnet.

   • Copy your private SSH key to the HAProxy Enterprise server.

     nix
     scp -i my-private-key.pem ./my-private-key.pem ubuntu@35.181.155.36:~/

     nix
     scp -i my-private-key.pem ./my-private-key.pem ubuntu@35.181.155.36:~/

   • Connect to the HAProxy Enterprise server through its public IP address.

   • If necessary, change the permissions of your private key that has been copied to the HAProxy Enterprise server:

     nix
     chmod 600 my-private-key.pem

     nix
     chmod 600 my-private-key.pem

   • Connect to the web server through its private IP address.

     nix
     ssh -i ~/my-private-key.pem ec2-user@10.0.148.139

     nix
     ssh -i ~/my-private-key.pem ec2-user@10.0.148.139

   • Install the NGINX web server.

     nix
     sudo amazon-linux-extras install nginx1
     sudo systemctl enable nginx
     sudo systemctl start nginx

     nix
     sudo amazon-linux-extras install nginx1
     sudo systemctl enable nginx
     sudo systemctl start nginx

Add the web server to the HAProxy Enterprise configuration Jump to heading #

To register the web server with the load balancer:

1. Connect to the HAProxy Enterprise instance through its public IP address.

2. Edit the file /etc/hapee-<VERSION>/hapee-lb.cfg.

3. Change the backend be_app section to include the private IP address of your web server.

   haproxy
   backend be_app
     balance            roundrobin
     server app1        10.0.148.139:80 check

   haproxy
   backend be_app
     balance            roundrobin
     server app1        10.0.148.139:80 check

4. Save the file.

5. Reload the HAProxy Enterprise configuration:

   nix
   sudo systemctl reload hapee-<VERSION>-lb

   nix
   sudo systemctl reload hapee-<VERSION>-lb

6. When browsing to the public IP address of the HAProxy Enterprise load balancer, you should see the web server’s web page.

Optional: Deploy a second HAProxy Enterprise instance Jump to heading #

You can achieve high availability for your load balancing tier by adding a second HAProxy Enterprise instance. Each subnet in a VPC resides in an availability zone. By launching HAProxy Enterprise instances in separate subnets, you gain protection from failure of a zone.

During this procedure, you will create an Amazon Network Load Balancer (NLB) to route traffic to both HAProxy Enterprise instances, doubling your load balancer capacity.

To create a second load balancer:

1. Repeat the steps in the Launch the HAProxy Enterprise AMI procedure, but assign the second instance to the other public subnet. Use the security group you already created for the first instance.

2. Copy the load balancer configuration, /etc/hapee-<VERSION>/hapee-lb.cfg, to the new load balancer and reload the hapee-<VERSION>-lb service.

3. Create a target group that the AWS NLB will use to send traffic to your HAProxy Enterprise instances:

   • Open the Amazon EC2 console.

   • From the EC2 Dashboard, click Target groups under Load Balancing, then Create target group.

   • On the Specify group details screen, set the following fields:

     Field	Description	Example value
     Target type	Choose how AWS NLB determines which instances to route traffic to.	Instances
     Target group name	A name for the group of HAProxy Enterprise instances being targeted.	load-balancers
     Protocol	The protocol by which the HAProxy Enterprise instances listen for incoming traffic.	TCP
     Port	The TCP port at which the HAProxy Enterprise instances listen for incoming traffic.	80
     VPC	The VPC where you created your HAProxy Enterprise instances.	vpc-0146c0c368ac64143
     Health check protocol	The protocol by which the AWS NLB will send periodic health check probes.	TCP

   • Click Next.

   • On the Register targets screen, select the HAProxy Enterprise instances to include in the target group. Then click Include as pending below.

   • Click Create target group.

4. Create an AWS NLB to route traffic to both HAProxy Enterprise instances:

   • From the EC2 Dashboard, click Load Balancers, then Create load balancer.

   • Choose to create a Network Load Balancer.

   • On the Create Network Load Balancer screen, set the following fields:

     Field	Description	Example value
     Load balancer name	A name for the AWS NLB	my-nlb
     Scheme	Whether the Network Load Balancer will be internet facing.	Internet-facing
     IP address type	Whether your subnet uses IPv4 and IPv6 addresses, or only IPv4.	IPv4
     VPC	Choose the VPC where you launched your HAProxy Enterprise instances.	vpc-0146c0c368ac64143
     Mappings	Select the availability zones of your targets. Since you launched HAProxy Enterprise instances in both availability zones, select both. Then choose the public subnets.	us-east-2a, us-east-2b
     Lisenter	Choose the protocol and port at which the AWS NLB will receive traffic. Set the Default action to the target group you created before.	TCP / 80

   • Click Create load balancer.

     Once the AWS NLB has been provisioned, you will be able to reach your web application at the new DNS name shown in the AWS NLB load balancer’s details.
