![]() an AWS account (you can create your account here if you don’t already have one),.To work through the examples in this post, you’ll need: create an AWS CodePipeline with CloudFormation (part 3).add an Amazon RDS Postgresql database to your stack with CloudFormation (this post, part 2), and.automate the provisioning of your Amazon EC2 instance using AWS CloudFormation ( part 1),.Both part 1 and part 2 set you up to do that.Īs a reminder, here’s what we covered and where we’re going: And eventually, you want to introduce a continuous integration/continuous deployment (CI/CD) pipeline to automate the build, test, and deploy phases of your release process. And since RDS is a managed service, you won’t have to do operating system patches or database patches - it’s all managed for you. In this post, part 2, you’ll add an Amazon RDS Postgresql database to the CloudFormation template you built in part 1 so that both the EC2 instance and the database can be provisioned together as a set of resources. In the past, it was running on the same instance as your webapp and sometimes web app traffic impacted the database and vice versa. In addition to the EC2 instance, you also need a Postgresql database. Bugs introduced into production code are more difficult and expensive to fix and your customers were ultimately the ones who suffered. All of this has been error prone and time consuming. ![]() When you built the EC2 instance manually in the past, you were seeing inconsistencies between environments, had to manually test your infrastructure setup, manually deploy your team’s web app, which happens all to infrequently. If you are starting your DevOps engineer journey, look at the comprehensive guide to becoming a DevOps engineer.In part 1, we automated the provisioning of your Amazon EC2 instance using AWS CloudFormation. In this guide, we looked at the steps to install PostgreSQL on an Amazon Linux ec2 server.įor the Ubuntu server, Checkout the PostgreSQL installation on Ubuntu.įor the Redhat server, Checkout the PostgreSQL installation on RedhatĪlso, if you are using Kubernetes, check out the guide on setting up PostgreSQL statefulset on Kubernetes ConfigĬonfig files location ( nf & pg_hba.conf ) The following table contains important PostgreSQL configurations on the Amazon Linux ec2 server. Now, in the ec2 security group of the Amazon Linux ec2 server, allow incoming traffic on port 5432, which is the default port used by PostgreSQL Important PostgreSQL Server Configurations on Amazon Linux To apply all the changes, restart the PostgreSQL service using the following command. Next, open /var/lib/pgsql/data/pg_hba.conf file sudo vi /var/lib/pgsql/data/pg_hba.confĪdd the following to the end of the file to allow client connections to all databases. This will allow connections from any IP address. Uncomment and change it to “ listen_addresses = ‘*’“. Locate the line that starts with “ listen_addresses“. ALTER USER postgres PASSWORD 'myPassword' Enable Remote Connection For PostgreSQL on Amazon Linuxīy default the remote PostgreSQL connection is disabled. You need to add the following configuration to enable remote connectivity. Replace myPassword with the required password. Set the password for the Postgres user so that we can use it to log in remotely. Now, let’s set a password for the default Postgres user and secure it.įirst login to the database using the following command. sudo systemctl status postgresql Set Password For Postgres User Step 6: Check the status of PostgreSQL using the following command. Step 5: Add the PostgreSQL service to the system startup. sudo amazon-linux-extras enable postgresql14 At the time of writing, PostgreSQL 14 is the latest package available in the extras library. Install the PostgreSQL amazon extras repository. Step 2: PostgreSQL is part of the amazon extras library. Step 1: Let’s upgrade the system Yum packages. Install PostgreSQL on Amazon Linuxįollow the steps given below to install the latest version of PostgreSQL on RedHat Linux It covers installation, configuration, and enabling remote connection. If you want to install PostgreSQL on Amazon Linux (AWS ec2), this guide is for you.
