This article will help you to how to utilize introduce s3cmd on CentOS and RHEL Systems and manage s3 bucketvia commad line in simple steps.
On CentOS / RHEL:
All the users of RHEL and CentOS with all other derived distributions. Create a s3tools.repo file in /etc/yum.repos.d directory and add following content
# vim /etc/yum.repos.d/s3tools.repo
[s3tools] name=Tools for managing Amazon S3 - Simple Storage Service (RHEL_6) type=rpm-md baseurl=http://s3tools.org/repo/RHEL_6/ gpgcheck=1 gpgkey=http://s3tools.org/repo/RHEL_6/repodata/repomd.xml.key enabled=1
Install s3cmd Package
After adding s3tools repository we can simply install s3cmd. You can install it using simply executing following commands on your system.
# yum install s3cmd

After getting key files, use below command to configure s3cmd om CentOS Systems.
# s3cmd --configure
Enter new values or accept defaults in brackets with Enter. Refer to user manual for detailed description of all options. Access key and Secret key are your identifiers for Amazon S3 Access Key: xxxxxxxxxxxxxxxxxxxxxx Secret Key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Encryption password is used to protect your files from reading by unauthorized persons while in transfer to S3 Encryption password: xxxxxxxxxx Path to GPG program [/usr/bin/gpg]: When using secure HTTPS protocol all communication with Amazon S3 servers is protected from 3rd party eavesdropping. This method is slower than plain HTTP and can't be used if you're behind a proxy Use HTTPS protocol [No]: Yes New settings: Access Key: xxxxxxxxxxxxxxxxxxxxxx Secret Key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Encryption password: xxxxxxxxxx Path to GPG program: /usr/bin/gpg Use HTTPS protocol: True HTTP Proxy server name: HTTP Proxy server port: 0 Test access with supplied credentials? [Y/n] Y Please wait, attempting to list all buckets... Success. Your access key and secret key worked fine :-) Now verifying that encryption works... Success. Encryption and decryption worked fine :-) Save settings? [y/N] y Configuration saved to '/root/.s3cfg' Uses of s3cmd Command Line
Once configuration is successfully completed. Now find below command details to how to manage s3 buckets using commands.
1.Creating New Bucket
You can create a new bucket in Amazon s3 by using below command. It will create bucket named techoism_code in your account.
# s3cmd mb s3://techoism_code
Bucket 's3://techoism_code/' created
2. Uploading file in Bucket
Using Below command we will upload any file to s3 bucket using s3cmd command.
# s3cmd put tech.txt s3://techoism_code/
tech.txt -> s3://techoism_code/tech.txt [1 of 1] 190216 of 190216 100% in 0s 1668.35 kB/s done
3. Uploading Directory in Bucket
Also We can upload entire directory in s3 Account. We use -r to upload it recursively like below.
# s3cmd put -r backup s3://techoism_code/
backup/tech1.txt -> s3://techoism_code/backup/tech1.txt [1 of 2] 9984 of 9984 100% in 0s 18.78 kB/s done backup/tech2.txt -> s3://techoism_code/backup/tech2.txt [2 of 2] 0 of 0 0% in 0s 0.00 B/s done
Verify you are not including slash in transfer directory named backup (eg: backup/), else it will transfer only content to backup directory only.
# s3cmd put -r backup/ s3://techoism_code/
backup/tech1.txt -> s3://techoism_code/tech1.txt [1 of 2] 9984 of 9984 100% in 0s 21.78 kB/s done backup/tech2.txt -> s3://techoism_code/tech2.txt [2 of 2] 0 of 0 0% in 0s 0.00 B/s done
4. List Data of S3 Bucket
If we have to list the objects of s3 bucket use ls switch with s3cmd.
# s3cmd ls s3://techoism_code/
DIR s3://techoism_code/backup/ 2013-09-03 10:58 190100 s3://techoism_code/tech.txt
4. List Data of directory in S3 Bucket
If we have to list the objects of any directory in s3 bucket use -r & ls switch with s3cmd.
# s3cmd ls -r s3://techoism_code/
2013-09-03 10:58 190318 s3://techoism_code/backup/tech1.txt 2013-09-03 10:58 197168 s3://techoism_code/backup/tech2.txt 2013-09-03 10:58 190100 s3://techoism_code/tech.txt
6. Download Files from Bucket
Some times if we need to download files from s3 bucket, Use following commands to download it.
# s3cmd get s3://techoism_code/tech.txt
s3://techoism_code/tech.txt -> ./tech.txt [1 of 1] 4 of 4 100% in 0s 10.84 B/s done
7. Remove Data of S3 Bucket
If we have to remove files & folder from s3 bucket, Use following commands to delete it.
Removing file from s3 bucket # s3cmd del s3://techoism_code/tech.txt
File s3://techoism_code/tech.txt deleted
Removing directory from s3 bucket # s3cmd del s3://techoism_code/backup
File s3://techoism_code/backup deleted
8. Remove S3 Bucket
If we have to remove s3 bucket, we can simply remove it using bellow command Before removing bucket verify its empty.
# s3cmd rb s3://techoism_code
ERROR: S3 error: 409 (BucketNotEmpty): The bucket you tried to delete is not empty
Above command failed because of s3 bucket was not empty
To remove bucket first remove all files & directory inside bucket and then use command again.
# s3cmd rb s3://techoism_code
Bucket 's3://techoism_code/' removed
9. List All S3 Bucket
Use following command to list all s3 buckets
# s3cmd ls
2015-04-29 12:38 s3://techoism_code
This post is very good and informative for installation and use of s3cmd on RHEL. I found one another informative post for s3cmd specifically for ubuntu too. Here is the link http://jee-appy.blogspot.com/2015/11/how-to-install-s3cmd-to-manage-aws-s.html
Ubuntu lover can see it.
