I have a Linux elastic beanstalk app running on aws. I need to figure out what folders the apps are installed in order to create a cronjob correctly.
Is it possible to open a terminal to ebs server?
Yes it is possible. To SSH to the Elastic Beanstalk Instance, you will need to use the EC2 key pairs and configure the Security Groups allowing SSH access from the client.
If you place the server in a private subnet, you might need to create a Bastion Host in a public subnet within the same VPC. Then you can SSH to the Bastion host and SSH to your sever from there.

Can you install MySQL for AWS Elastic Cloud Compute (EC2) directly on the instance? I can't afford to purchase a separate RDS instance at the moment.
My website is setup on AWS EC2 already and now I'm going to try out some features with a database. I need to set up the instance to run on the EC2 localhost and connect it to my website to store my user data.
So first you need to separate XAMPP from mysql in your thought process. XAMPP is a tool only for your local development. You can set up a database on the Elastic Cloud Compute (EC2) instance similarly to how you set up your XAMPP config locally.
Here are the official docs on how to install a full LAMP stack on an EC2 instance running the Amazon Linux AMI - https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-LAMP.html
I have an ElasticBeanstalk application that uses Docker to run a small Laravel PHP API.
The app cannot connect to MySQL when running in ElasticBeanstalk.
The MySQL DB is a publically available AWS RDS instance.
I've run my Docker container locally and the app can connect just fine.
When I deploy to ElasticBeanstalk the app cannot connect...
Can anyone point me in a direction to help debug this?
SOLUTION
For anyone else who stumbles on this:
The solution was to create a new security group for both the EC2 instances and the RDS database. The two security groups opened up access via port 3306 for the instances and the database.
I also ensured the EC2 instances were available across every subnet and in the same VPC as my database.
Taken from the answers below and bit of help from a SysOps friend of mine.
You may want to check the EC2 Security Group Rules attached to Elastic Beanstalk to allow TCP at port 3306 for MYSQL type.
High chance that your ec2 instance does not have a public ip assigned to it. If you're trying to connect to the public IP of RDS without a public ip on the ec2 instance you won't be able to.
The ec2 instance will either need a public ip or it will need to have external internet connectivity through NAT.
We have mysql databases which we want to host on AWS RDS and want to use in Azure VM and web app. Both of them located in Singapore region.
Is this possible? If yes, How? What are pros and cons? And how to do this?
You have two options, build a Amazon VPC /Azure Network VPN tunnel by your own, with something like a cisco instance or linux vpn packages, or make your mysql amazon rds public accessible and set up ssl encrypt connection to the db for more information see this doc

I have a Single-Instance EB environment, with an elastic ip. However, I can't seem to ssh to the current instance using the elastic ip, only the private ip. How do I fix it?
When I try to ssh using the elastic ip, it just hangs.
Your Elastic Beanstalk instance won't have port 22 open by default. Either you have to add a security group that has it open (can also add port 22 to an existing security group that is already used) or you can use the CLI to SSH to your instance.
eb ssh
It will open the port for you automatically while you are logged in.
Is it possible to do the following?:
I have a local Mac running OS X Lion with a MySQL Server installed which runs different processes regularly and stores data into a local DB.
On the other hand I have an Amazon EC2 instance.
What I would like to do is to use the Amazon instance to perform certain cronjobs (using its own resources) but connecting to the data that is on my localhost (my computer) and performing basic SQL actions like updating the data, inserting, etc.
I don't know if this helps, but I have a static IP. Is there any way I can "open" my IP so the Amazon instance can recognize my home computer as a valid MySQL server?
Thanks for your help, any tip in the right direction will be much appreciated.
If your EC2 instance is connecting to your local db you'll need a static IP locally. Well not need... but if you don't have it anytime you reset your router or loose power etc your ip will change. You can look into Dynamic DNS as well for your local instance.
Your ISP will not block your port on your local instance. This would be a firewall inside your network that is preventing you from connecting to mysql or a configuration with mysql itself. Users can only connect to mysql from certain IP addresses.
You would have to open up the mysql port on your firewall if you are using one, have the mysql client installed on your EC2 instance, and make sure that the user that had proper grantable permissions.
That said why not run cron locally on the mac?
If you can login to your server via SSH then there's no need to open any other port and no static IP is required. You can use SSH port forwarding instead. From your local machine run:
ssh -C -R 5555:127.0.0.1:3306 <your-server-host>
Now you should be able to connect to your Mac's database running on localhost:3306 from the remote server at localhost:5555.
