Hi all! I've got both FileZilla and Terminal/SSH connected to my EC2
instance, but am having a great deal of trouble uploading files via either
client. Trying to upload the create_db_and_user.sql file and the ROOT.war
file but get 'permission denied' errors in FileZilla and 'Permission denied
(publickey). lost connection' errors in terminal. However, moving the
create_db file to the 'EC2-user' folder instead of 'home' worked; seems
like only certain folders are locked. Since I connected with the .pem I
thought permissions would be open? What's going on?
Managing file and directory permissions will be one of your joys as a Linux
system administrator. By default, your ssh sessions are in the context of
the ec2-user, but you can use the "sudo" command to execute commands as the
root user instead. Using sudo, you can change file and directory ownership
and permissions. But you will want to be very careful about what you do and
how you do it, as you can compromise the security of your server by opening
permissions willy-nilly. I'm sure that you can find lots of information
about Linux permissions, Tomcat server management, and more on the web.
EC2 makes it deceptively easy to get started and make progress, but
ultimately managing a Linux server is something that requires quite a lot
in terms of Unix system-administration skills. (Just wait till something
goes wrong! Your ability to respond will be extremely limited if you aren't
an expert sysadmin.)
Best,
Chris

the following works
sudo chmod -R 777 /usr/share/tomcat6/webapps

Thanks for the word of caution I figured it was something like that, but
do you or anyone else have anything more concrete about this issue
specifically...i.e. which permissions to change during the configuration as
outlined here https://github.com/opendatakit/opendatakit/wiki/Aggregate-AWS-Install? I
had to run chmod 400 on my key in setting up the SSH; and the git mentions
chmod 755 to access the webapps folder, but doesn't look like I should be
having trouble uploading to the home directory as ec2-user.
Best,
Jordan

Sorry, no, I don't really have any easy advice on this. You're well outside
the ODK realm now and into the realm of Tomcat+Linux, and so you should be
able to find tons of Googlable resources to help you. After 3+ years of
managing these kinds of servers, I still find myself having to Google and
read through Stack Overflow explanations far more often than I'd like.
Best,
Chris
