问题 I am starting a Amazon Linux instance (ami-fb8e9292) using the web console, pasting data into the user data box to run a script upon startup. If I use the example given by amazon to start a web server, it works. But when I run my own script (also a #!/bin/bash script), it does not get run. If I look in var/log/cloud-init.log , it gives no useful information on the topic: May 22 21:06:12 cloud-init[1286]: util.py[DEBUG]: Running command ['/var/lib/cloud/instance/scripts/part-001'] with allowed

Do I need to have the database on RDS where every instance

问题 I am just setting up nginx as a webserver that proxies directly to a tomcat app server. When the user connects to my website Nginx should redirect the request to port 8080 where the tomcat app server is running. I am doing everything on amazon ec2 instance that is running Redhat 7. What I have so far is this: nginx.conf file user nginx; worker_processes 1; server { listen 80; server_name mydomainname; access_log /var/log/nginx/example.log; error_log /var/log/nginx/example.error.log; location

问题 I am trying to find out list of reserved instances that are active. aws ec2 describe-reserved-instances --filters "Name=instance-state-State,Values=active" --query 'Reservations[].Instances[].Tags[?Key==`Name`].Value[]' The above command does not work, and I think the Name field is not right.
