So here's the deal, I'm trying to run a little webmail server for testing purposes off amazon's EC2 server, I'm looking at their guide for setting the hostname, and the directory they mention /etc/sysconfig/ doesn't exist, let alone the file I'd be expected to edit, when I go to the actual hostname file (as if I was running the server) cd /etc/ then nano hostname I can read but I don't have write permission, so when I go to save the file it tells me I don't have the permissions, so I looked it up, and it says to edit /etc/sysconfig/network which would be fine and dandy, if the directory actually existed. Pretty new to all of this, so if I missed anything that could help you figure out what's going on please let me know! Thanks in advance!
It sounds like the base AMI you are using for your instance is not one of Amazon's AMI's. What AMI is the instance based on?

I've been trying to Run cartography on my EC2 account for the last 2 days. I have no previous knowledge of Neo4j, But following their installation process doesn't work.
First I've tried to install Neo4j using rpm instructions for Neo4J website, no success acessing Neo4j on port 7474. Error: Connection refused.
Then I gave up trying to make Neo4J work on an EC2 installation, and used their MarketPlace AMi- Works Like a charm but I don't know what is being installed on that AMI. So I decided to install and run cartography on this instance.
My first problem was installing python, pip and java correctly. After everything working, I've discovered neo4j bolt port used my public IP, not my localhost. After thatI was able to finally execute Cartography, but Not it's giving me the following error:
neobolt.exceptions.ClientError: Supplied bookmark [FB:kcwQ40omSYgvSzKPpCQTXDOcCBSQ] does not conform to pattern neo4j:bookmark:v1:tx
Have Anyone really was able to use this?, every step along the way requires some specific libraries.
Thanks !
I maintain cartography and hope I can help (wish I saw this earlier though haha)
Few things to check:
Are you using Neo4j 4.x? cartography currently only supports 3.5.x.
To run for one AWS account,
AWS_PROFILE=profilename cartography --neo4j-uri <uri for your neo4j instance; usually bolt://localhost:7687>`
To run multiple accounts, set up an AWS config file and run
AWS_CONFIG_FILE=/path/to/your/aws/config cartography --neo4j-uri <uri for your neo4j instance; usually bolt://localhost:7687> --aws-sync-all-profiles
(see https://github.com/lyft/cartography/blob/master/docs/setup/install.md#cartography-installation)
If you have more questions feel free to open a GitHub issue or start a thread on our Slack (can talk about more specialized setups like if you're using containers or anything like that too)
I am trying to use a development Endpoint to interactively run and edit ETL scripts but there seems to some issues in the development endpoint just after creating it as i am getting errors in scala/python REPL and also unable to do SSH tunnel to remote interpreter.
Let me explain what i did exactly - I created a development endpoint in the AWS console with all the default configurations. While creating the development endpoint i only provided three things 'Development endpoint name' and 'IAM Role' and my 'pub ssh key'. This is how it looks after creation
Then Right After creating the endpoint i am connecting to the spark/python REPL, I am able to connect to them successfully but within couple of minutes of connecting, the REPL starts throwing errors without writing a single line of code. This is happening in all the REPL present in the development endpoints.
Also When I am trying to do SSH tunneling to remote interpreter to connect my Local Zeppelin Notebook it is throwing - "bind: Cannot assign requested address".
Couple of things that are working though -
Able to do ssh to the endpoint.
Created a Sagemaker notebook in the AWS glue that is attached to this development endpoint and this notebook seems to be working fine, although surely it is adding an additional cost and i don't want to continue using it.
Can anyone please help what am i doing wrong? Am I missing any important steps that is needed to be done on the machine right after creating the development endpoint?
Thanks in Advance!
Not very sure about this error but if you are using it smaller datasets then probably you would like to use Docker implementation as it will not add any additional cost and you can go on with your developments.
You can refer this blog on how to set it up

i try to access some s3-items (json-files) from an neo4j-database they is running in a EC2-machine.
I have some problems to understand, what is meaned with "endpoint" and "port" in the APOC-Manual.
Screenshot from APOC Manual
I downloaded all in the picture described Plugins and my ec2 is running in a VPC.
I'm new in AWS, sorry for stupid asking :/
and thanks for your reply.
Based on the comments, the issue was using incorrect standard-endpoint than the required one.
I have a project deployed on EC2 instance and is up.
But sometime when I login through FTP and transfer the updated build to the EC2, some of my project file gets missing.
After a while those set of files is seen listed at the same place.
Couldn't relate why these unexpected behavior is happening. Let me know if anyone has faced similar kind of situation.
Or anyone can give me a way to know what all logins are being done through FTP and SSH on my EC2.
Files don't just randomly go missing on an EC2 instance. I suspect there is something going on and you'll need to diagnose it. There is not enough information here to help you but I can try point you in the right direction.
A few things that come to mind are:
What are you running to execute the ftp command? If it's appearing after some time, are you sure it's just not in progress when you first check then it appears when it's done? are you sure nothing is being cached?
Are you sure your FTP client is connected to the right instance?
Are you sure there are no cron tasks or external entities connecting to the instance and cleaning out a certain directory? You said something about the build, is this a build agent you're performing this on?
I highly doubt it's this one but: What type of volume are you working on? EBS? Instance Store? Instance Store is ephemeral so stopping/starting the instance can result in data being lost.
Have you tried using scp ?
If you're still stumped, please provide more info on your ec2 config and how you're transferring the file.
I have set up an elastic beanstalk deployment of Drupal to host a Drupal built website.
When I start up my ec2 instance, I go through the installation steps of setting up Drupal.
However, when the instance is Restarted, or Stopped, restarting the instance goes back to this page!
How can I configure the instance so that these installation steps do not need to be repeated even when the instance goes down. This is quite worrying as I am looking to host my website this way.
Any help on this issue would be greatly appreciated!
This step means that drupal can't find database or it can find it but installation is not done yet (required tables are not created). So if you pass installation and you see again this screen it can mean 2 things:
Your database configuration is lost, so drupal can't find DB.
DB configuration file is ok, but DB it self is lost so configuration must be done again.
So first check what is the problem in your case and then solve it. Probably since you are installing in instance, DB configuration is then recorded and then lost when your box expires. If so...find a way to make permanent change do config file (should be /sites/default/settings.php).
