Executing AWS CLI command from php results in Unable to locate credentials

Question

I am trying to run aws s3 cp command from within php code using shell exec. Following is the php code.

echo shell_exec("sudo aws s3 cp s3://<bucket>/somefolder/somefile s3://<bucket>/someotherfolder/somefile --region ap-southeast-1 --acl public-read");

The file is not getting copied and The output from echo is the following

"Unable to locate credentials Completed 1 part(s) with ... file(s) remaining"

Note1: I have already set the credentials using aws configure command

Note2: If I run the exact same command directly from terminal, it works fine.

Any idea?

Answer 1

The AWS CLI sets credentials at ~/.aws/config, and the aws php sdk looks for them at ~/.aws/credentials.

So:

cd ~/.aws
mv config credentials

Solved what I think is the same problem for me.

Answer 2

From your terminal, you can then run:

$ cat ~/.aws/config
[profile eb-cli]
aws_access_key_id = XXXXXX
aws_secret_access_key = XXXXXX

$ aws configure

and then you will be asked for 4 values:

1. Access Key ID (Access Key) - This is the shorter of the two values.
2. Secret Access Key
3. Default region name (type in 'us-east-1')
4. Output format (type in 'json')

then

$ aws s3 sync s3://<bucketname>

Answer 3

Looks like a permission/location issue of the configuration file.

Credentials set using AWS CLI, is written in a special file in the current user's path. PHP I guess is executing in other permissions (not as the same user). I would suggest you should keep the configs in a separate files and pass to the CLI this way. You also need to ensure that the specific environment variable is available inside PHP shell_exec.

Answer 4

To extend off of user1464317:

I found this problem exists with Yosemite vs Mavericks. The AWS CLI for Mavericks looks for permissions in "~/.aws/config", where Yosemite looks in "~/.aws/credentials".

If using cron, you can set the environment variable in crontab -e like so:

# Mavericks
AWS_CONFIG_FILE="/Users/YOUR_USER/.aws/config"

# Yosemite
AWS_CONFIG_FILE="/Users/YOUR_USER/.aws/credentials"

Or you do as user1464317 implied, move the file over:

mv config credentials

In order to solve the issue, Follow the following steps:

1. copy .aws directory from /home/non-rootUser/.aws to /var/www
2. Now change the directory to /var/www (cd /var/www)
3. Change the permissions: /www$ sudo chmod -R 755 .aws
4. Change Ownership /www$ sudo chown -R $USER:$USER .aws
