CentOS.org | 2002_01Linux/Unix, CentOS 7 - 64-bit Amazon Machine Image (AMI)
Doesn't work with user-data script!
These official CentOS images do not work with user-data scripts! just a simple script like below will fail:
#!/bin/bash
echo "asdf" > /tmp/foo.txt

Works extremely well
I can't really ask for anything else, this is an extremely basic CentOS with nothing superfluous added onto it so it gets my five stars.
Improving!
Glad to see the CentOS team publishing images more frequently as well as adopting better practices for cloud images!
One annoyance still remains that prevents me from recommending these images: the fact that the root EBS volume is not set to "delete on terminate" which is pretty standard for all other AMIs. Without this, my users leave tons of unused EBS volumes laying around which drives up my AWS bill
Excellent!
I'm using this to run Plesk Onyx on one of the new m5 EC2 instances (since the instance store with Plesk pre-installed only provides support for m4 or earlier). Everything is blazingly fast, even after weeks of uptime, and with reserved instance pricing I really feel like I'm getting a great value.
I would highly recommend this image for hosting any web application and for those seeking a highly stable, high performing, yet lightweight OS, capable of handling most anything a typical user would need.
Very useful
Good OS overall. Specifically for this product, clicking on the Wiki URL gave me a "page not found" message. But I'm not a first-time CentOS user, so it didn't bother me.
No new image is available to mitigate Meltdown and Spectre
Looking at the images available, I see no new image is available to mitigate Meltdown and Spectre. This is basic. This is a crucial update and customer are supposed to upgrade on their own
Instance limitations makes this image close to useless
This image is locked to just a number instance types. If you plan to change instance type in the future DO NOT USE THIS IMAGE!
AWS Support can't do nothing about it!
Bug report
Will the new version of centos7, Did you fix the bug "modify the system time then the system crash" ? Hope to be answered
Create a swap file!
Please be aware this instance is pretty much useless with less than 1GB of ram unless you create a swap file. This process is really simple and all you need is a 2GB swap partition to get anything done. Currently running nano for all my purposes.
Only issue is kdump won't start on instances with < 2GB ram
Only issue is kdump won't start on instances with < 2GB ram, tracked this down to the crashkernel=auto setting. Changing to pre-determined value seemed to allow kdump to start successfully.
