Configure S3cmd to Connect WordPress Server to Exoscale

Next, you will need to configure the S3cmd using the Exoscale Access key and Secret key. You will require the following details to configure S3cmd:

• Access Key: FEO2c60fbb123a7c263cc53751d

• Secret Key: KhnddL-AA8DpYRG8o_nlnsdngPosi5KfsaoSEdA1s9k

• Region: Frankfurt-de-fra-1

• S3 Endpoint: sos-de-fra-1.exo.io

• host_bucket: %(bucket)s.sos-de-fra-1.exo.io

Next, run the following command to configure S3cmd tool:

s3cmd --configure

You will be asked to provide your Exoscale Access Key, Secret Key, Region, and Endpoint as shown below:

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. Leave them empty for using the env variables.
Access Key: FEO2c60fbb123a7c263cc53751d
Secret Key: KhnddL-AA8DpYRG8o_nlnsdngPosi5KfsaoSEdA1s9k
Default Region [US]: Frankfurt-de-fra-1
 
Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
S3 Endpoint [s3.amazonaws.com]: sos-de-fra-1.exo.io
 
Use "%(bucket)s.s3.amazonaws.com" to the target Amazon S3. "%(bucket)s" and "%(location)s" vars can be used
if the target S3 system supports dns based buckets.
DNS-style bucket+hostname:port template for accessing a bucket [%(bucket)s.s3.amazonaws.com]: %(bucket)s.sos-de-fra-1.exo.io
 
Encryption password is used to protect your files from reading
by unauthorized persons while in transfer to S3
Encryption password:
Path to GPG program:
 
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 only be proxied with Python 2.7 or newer
Use HTTPS protocol [Yes]:
 
On some networks all internet access must go through a HTTP proxy.
Try setting it here if you can't connect to S3 directly
HTTP Proxy server name:
 
New settings:
Access Key: FEO2c60fbb123a7c263cc53751d
Secret Key: KhnddL-AA8DpYRG8o_nlnsdngPosi5KfsaoSEdA1s9k
Default Region: Frankfurt-de-fra-1
S3 Endpoint: sos-de-fra-1.exo.io
DNS-style bucket+hostname:port template for accessing a bucket: %(bucket)s.sos-de-fra-1.exo.io
Encryption password:
Path to GPG program: None
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...
Not configured. Never mind.
 
Save settings? [y/N] y
Configuration saved to '/root/.s3cfg'

Once the S3cmd is configured, you can verify your bucket information using the following command:

s3cmd info s3://wordpress-exoscale/

You will get the following output:

s3://wordpress-exoscale/ (bucket):
Location: de-fra-1
Payer: BucketOwner
Expiration Rule: none
Policy: none
CORS: <?xml version="1.0" encoding="UTF-8"?><CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"></CORSConfiguration>
ACL: snapshooter: FULL_CONTROL

Use S3cmd to Backup WordPress to Exoscale Bucket

First, log in to your WordPress server and connect to the MariaDB shell with the following command:

mysql -u root -p

Once you are log in, list all available databases using the following command:

MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| wordpress |
+--------------------+

Next, backup your WordPress database using the following command:

mysqldump -u wordpressuser -p wordpress > wordpress.sql

Next, run the S3cmd command to copy the wordpress.sql file to the Exoscale Bucket:

s3cmd put wordpress.sql s3://wordpress-exoscale/

You should see the following output:

upload: 'wordpress.sql' -> 's3://wordpress-exoscale/wordpress.sql' [1 of 1]
8388608 of 8388608 100% in 1s 6.46 MB/s done
upload: 'wordpress.sql' -> 's3://wordpress-exoscale/wordpress.sql' [1 of 1]
8388608 of 8388608 100% in 0s 13.09 MB/s done

Next, run the S3cmd command again to copy the WordPress website data to the Exoscale Bucket:

tar -czvf - /var/www/html/wordpress | s3cmd put - s3://wordpress-exoscale/wordpress.tar.gz

Output:

upload: '<stdin>' -> 's3://wordpress-exoscale/wordpress.tar.gz' [part 4 of -, 14MB] [1 of 1]
15529549 of 15529549 100% in 1s 11.31 MB/s done

You can now verify all backups on the Exoscale Bucket using the following command:

s3cmd ls s3://wordpress-exoscale

You will get the following output:

2022-07-28 06:14 8388608 s3://wordpress-exoscale/wordpress.sql
2022-07-28 06:14 62715469 s3://wordpress-exoscale/wordpress.tar.gz

You can also log in to the Exoscale Bucket and verify your WordPress backup files as shown below:
