I am running through an issue to connect to the eb instance of aws.
Whenever I try to log in, it comes back with that issue :
ERROR: The current user does not have the correct permissions. Reason: Operation Denied. Signature expired: 20200419T095048Z is now earlier than 20200419T095113Z (20200419T095613Z - 5 min.)
I found this link that explains that I need to synchronize my local machine with AWS one.
However, I am not able to find any documentation on doing that process for windows machine.
I am running window 10 and super newbie on AWS.
I try to deploy a flask application on beanstalk but I cannot connect to my EC2 Instance now.
Thanks for your help.
I found that you need to update your clock on your machine so it is being sync with the internet.
Window provides several clock server to enable that.
here is an article for Linux system : https://aws.amazon.com/blogs/aws/keeping-time-with-amazon-time-sync-service/
And how to change time for windows machine : https://www.windowscentral.com/how-manage-time-servers-windows-10

I trying to setup AWS Cloud9 and am running into a wall each time I try to setup my environments. Once I create the environment and start following this guide https://docs.aws.amazon.com/cloud9/latest/user-guide/sample-lamp.html to configure the LAMP server, through the Cloud9 IDE terminal, the environment will just stop responding. Once I try to reload the IDE I get the follow error;
Cannot connect to instance error message.
Rebooting the instance doesn't seem to resolve the error message. But any time I make a fresh instance it will let me work from anywhere to 30 seconds to 90 seconds before it stops responding.
I have looked through my VPC port settings, as well as security group settings, and they both appear to the correct.
VPC inbound rules VPC outbound rules Security Group inbound
rules Security Group outbound rules
Additionally, I was using the default t2.micro instance until I read this post AWS Cloud9: Cannot open environment and have tried with the t2.small but I am still getting the same results.
Any help with where else to look or what else to try would be much appreciated!
Edit: It appears to be random when it stops and freezes, for example when making a m4.large instance. It froze while I was setting up the sudo mysql_secure_installation.
Once I typed "Y" it wouldn't let me press enter. Reloading the IDE gave me the VPC error.
Welcome to SO! When I use cloud9 I tend to use m4.large for anything that's non-trivial. If you're running Apache and MySQL on the same host I would definitely try the m4.large instance. It's $0.10/hr (pricing) so you could try it out fairly cheaply. I'm guessing that's the root of the issue. If you're still having the issue please repost here and we can check further.
Just to confirm:
- You can connect to the instance at least once (even if for a few seconds)
- You see the IDE and can type for 30-60 seconds before it stops responding
If you can't connect that's likely a different issue.
I'm trying to install oracle on AWS redhat instance. Follow the steps given on this url: http://www.davidghedini.com/pg/entry/install_oracle_11g_xe_on And when I run config command as follows
/etc/init.d/oracle-xe configure
It gives following error.
Database Configuration failed. Look into
/u01/app/oracle/product/11.2.0/xe/config/log for details
When I check the log files it shows following errors.
ORA-01034: ORACLE not available Process ID: 0 Session ID: 0 Serial
number: 0
It seems specific issue on AWS cloud instance.
Is it because of swap memory?
Or is it because of port issue?
I'm using micro instance on it.
How can I get through?
this might be an EC2 security group issue and outbound access to the network on some port being used by the installer (license check, maybe?).
if your EC2 instance is very tightly locked down, you could test if it's a security group issue by adding a new Outbound security group rule to allow all TCP traffic out to anywhere on the internet (0.0.0.0/0)
for example, the install might be trying to hit a remote licensing server endpoint via HTTP or HTTPS but your security group doesn't allow that traffic out.
perhaps there's a 'verbose' flag that you can run the installer with that can give you more info about what it's failing on? HTH
I added a bad script in startup script, turned out this script is blocking and hence ubuntu instance can't boot up to ssh server and I can't ssh into it. Is there a way for me to go to the server console (like from VGA port)? like go to single-user mode or safe mode and fix it?
Thanks in advance.
I don't know of any way to obtain server console access or change boot modes on the EC2 instances...
I had the same issue sometime ago, and I ended up creating a temporary EC2 instance, mounting the root device from the original (failing) EC2 there, modifying the files, then reattaching the device and destroying the temporary instance. Note: you may end up paying more depending on which instance type you launch.
I have installed mysql 5.5 and tomcat 6 on an amazon ec2 windows micro instance. I am unable to access the pages deployed in tomcat from my local browser.It says The server at ec2-50-19-6-147.compute-1.amazonaws.com is taking too long to respond.
When i pinged using my command prompt, it says request time out.
Can somebody please help me??
Thank you in advance.
You need to check your security settings and make sure that the ports are open for inbound requests.
I created an instance of ubuntu ec2 yesterday and I was trying to configure it and I stopped the serer before going home last night, when I tried log on to the same instance using ssh from my ubuntu I am getting an error which says connection timed out. I am not able to login to the instance now
If you stopped the instance, and the instance was ebs-backed then you should be able to start it using the ec2 api.
Describe the instance using the ec2-describe-instances/instance-attributes api and use ec2-run-instance start it. Once started, use the above api to retrieve the public dns name.
Using this you should be able to login to that same machine again.
if you have terminated an instance-store based virtual machine, then you can kiss it goodbye.
