How to upload a lib for Tomcat in Amazon EC2

Question

I want to upload a lib to my Tomcat folder (in an EC2 instance). What i have done is:

scp -r -i /home/path_to_key/key.pem /home/path_to_file/file.jar ec2-user@my_address.compute.amazonaws.com:/home/ec2-user

This works perfectly only if I upload files in the "user" folder. But when i try to to upload a file in /opt/tomcat7/lib/ ? I receive this error:

scp: /opt/tomcat7/lib/file.jar: Permission denied

Any suggestions as to what i should do?

You need to set the proper privileges so that the ec2-user can write to the target directory. Try executing these two commands:

id

sudo ls -al /opt/tomcat7

Based on the error that you are getting i think the proper thing to do would be to add the ec2-user to the "tomcat7" group, then grant that group write access to the directory:

sudo usermod -a -G tomcat7 ec2-user sudo chmod -R g+w /opt/tomcat7
