I've set up an EC2 instance with LAMP stack. I'm in remote system explorer in eclipse right now, trying to find the file location of my database. Where does Amazon store the MySQL/database file?
Instead of using mysql in EC2 instance, you can use Amazon RDS instance for mysql. It is more easy to access the database.
If you want mysql in EC2 itself, you can access through port 3306.
eg: jdbc:mysql//ec2-xx-xx-xx.compute.awsamazon.com:3306/dbname

I have lunched AWS linus2 AMI and created database and setupAjax/ LAMP through puTTY web page in browser.Now I want to partition the application so that application itself is on one instance and the database resides on a database instance on ec2?
A typical architecture on AWS is:
An Amazon EC2 instance with the application, placed in a Public Subnet
An Amazon RDS database
The application on the EC2 instance can connect to the Amazon RDS database. The benefit of this architecture is that the EC2 instance can be updated and even replaced without impacting data stored in the database. Plus, if your application later grows to multiple EC2 instances, they can all communicate with the database.
Using an Amazon RDS database is preferable to running your own database on an Amazon EC2 instance because AWS takes care of deployment, updates and backups.
I am using a AWS console which show a running instance but when I check the storage in S3 there are no files in it. I have checked all the other storage options but unable to find any files. I need to check that which website is hosted on this instance. What can i do?
Moreover, I do not have .pem of the instance
I am working on a client website and we have a doubt that one of our website is hosted on AWS. We want to migrate that website from AWS to another host.
Please guide what is the best way to do this?
Thanks
Amazon EC2 uses Elastic Block Store (EBS) volumes for its file system, not S3. So if the web site is hosted by an EC2 instance, the files will most likely be stored on an EBS volume. To get access, you will probably need to log in to the instance using SSH or the AWS Session Manager. Alternatively, you can try and attach the volume to a different EC2 instance that you have access to.
Firstly S3 is for object storage, the instance runs off block storage using EBS and is where the file structure is located. Unless a job exists to manually copy content to S3 you will not find it there.
There are a few options you can perform to gain access:
You can try connecting using Sessions Manager assuming that the SSM Agent is running on the host.
You can try using instance connect if it is setup, this will allow you to use an SSH terminal by specifying a temporary pem.
You can create an AMI of the server and then launch a new instance from this AMI (the server will be running as if it is the server that you took the AMI from so be aware services will be running).
You can take a EBS snapshot of the server and attempt to launch a new volume from this. You would then mount it to a host.
Be aware that if this is a Windows host, connecting via regular RDP will require the Windows password of the host. If this is the case you will need to follow these instructions.
When you set up a new Elastic Beanstalk cluster you can access your EC2 instance by doing this:
eb ssh
However, it's not clear how to access the RDS instance.
How do you access an RDS in an Elastic Beanstalk context in order to perform CRUD operations?
The RDS command-line can be accessed from anywhere, by adjusting the RDS security group.
Check your AWS VPC configuration.
The security-group will need to be
adjusted to allow you to connect from a new source/port.
Find the security Group-id for the RDS.
Find that group in AWS Console > VPC > secuirty groups
Adjust the Inbound and Outbound Rules accordingly.
You need to allow access to/from the IP or security group that needs to connect to the RDS.
FROM: https://stackoverflow.com/a/37200075/1589379
After that, all that remains is configuring whatever local DB tool you would like to use to operate on the database.
EDIT:
Of additional note, if the ElasticBeanstalk Environment is configured to use RDS, the EC2 Instances will have environment variables set with the information needed to connect to the RDS.
This means that you can import those variables into any code that needs access.
Custom environment variables may also be set in Elastic Beanstalk Environment Configuration, and these too may be included this way.
PHP
define('RDS_HOSTNAME', getenv('RDS_HOSTNAME'));
$db = new rds(RDS_HOSTNAME);
Linux CommandLine
mysql --host=$RDS_HOSTNAME --port=$RDS_PORT -u $RDS_USERNAME -p$RDS_PASSWORD
RDS is a managed database service, which means it is that you can only access it through database calls.
If it is a MySQL database you can access through your EC2 instance through mysql like this:
mysql -u user -p password -h rds.instance.endpoint.region.rds.amazonaws.com
or set it up to work with your app with settings needed for that.
Make sure that you set up security groups correctly so that your EC2/other service has access to your RDS instance.
Update:
If you want what you are asking for then you should use an EC2 instance with a mysql server on. It would cost the same (even though a fraction of performance is lost in comparison). An EC2 instance you can turn off when you are not using as well.
I am trying to map a drive from an Amazon EC2 Instance of Windows Server 2008.
I have tried doing this the standard way of entering the IP (public and private) into the server field. My main goal is for users to be able to use login credentials to access drives on the Amazon EC2 instance.
I am using AWS Amazon Web Service RDS for database. I have set up a database instance but how should I add the tables in that database instance or create any new tables in the database? Any idea how to add table?
Which RDS are you using? I have been using RDS for MySQL for a long time. I create an RDS instance of MySQL and then connect to it from my laptop where I have install MySQL client program. Once I am connected, I can run all the MySQL commands just as if I ma connected to a remote database. I can create DB, Tables...blah blah..
You should provide information on the RDS instance that you are using and how your connecting to it.
Is your database in private or public subnet? That matters as it will affect how we can connect to it. If your RDS database is in a private subnet, then you cannot directly connect to it with a SQL client like MySQL Workbench from your PC.
I would advise you to put the database in private subnet for security concerns.
Now let's assume your database is in private subnet. What you can do is to rent a very cheap EC2 instance as a bastion instance in a public subnet. You can use SSH over TCP/IP or SSH tunneling to connect to this RDS instance even from outside your VPC as mentioned here https://www.youtube.com/watch?v=gM7JvNMOUQM.
Here is a blog that has some details of how to do it. https://bobbyhadz.com/blog/aws-cdk-rds-example
You can create a lambda function in the VPC, use an ORM to create migrations and call the function from the command line using aws command line tool.
If you manage to ssh to your EC2 instance you can connect to your database using MySQL command line tool.
mysql -h [DatabaseConncetivityEndpoint] -u [usernameOfDatabaseInstance] - p [password]
Make sure that you have installed MySQL client using > mysql -v. If not you can install MySQL client inside EC2 instance:
> yum update
> yum install mysql
Then, you can flow the normal MySQL operation on the database.
