 GRANT ALL PRIVILEGES ON piwik . * TO 'piwik'@'localhost';
 FLUSH PRIVILEGES;

 !!INSTALL GeoIP-DB first(including update URL)

 (if vhosts are not properly logged or anything try smth like below)

 ->Download Zip
 (unzip with webftp or smth)
 ->unzip -> results in "nextcloud" folder
 ->ftp can't put recursively , so maybe:
 lftp -e "mirror -R nextcloud nextcloud" -u FTPUSERNAME,FTPPASS HOSTNAME
 ^(you have to have the unzipped "nextcloud" folder in your current one , it puts to ftp root
 adjust db & stuff

 ##

 chain problems with nginx ?
 generate full chain in order (the right one !! )
 cd /etc/ssl/private/;cat /etc/letsencrypt/archive/targetdomain.website/privkey1.pem > nginx.key ; cat /etc/letsencrypt/archive/targetdomain.website/cert1.pem /etc/letsencrypt/archive/targetdomain.website/chain1.pem /etc/letsencrypt/archive/targetdomain.website/fullchain1.pem > crt.pem ; ln -s crt.pem ca.pem;/etc/init.d/nginx restart

 [minio]

 - setup minio ( does not allow subvolumes, in the few cases , bind mounts should help → need to be mounted before containerd )
 - get mc
 - run mc once and update ~/.mc/config.json (e.g. "vi  ~/.mc/config.json")

 example with user named customer.name and site named local in ~/.mc/config.json :
 we will generate a policy named like the user and the bucket has the same name
 - generate json like: 
 ############## backup.user-customer.name.json ###
 {
    "Version": "2012-10-17",
    "Id": "backup.user-customer.name",
    "Statement": [
        {
            "Sid": "ExampleStatement01",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::Account-ID:user/backup.user-customer.name"
            },
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:GetBucketLocation",
                "s3:ListBucket",
                "s3:ListMultipartUploadParts",
                "s3:AbortMultipartUpload",
                "s3:DeleteObject"
            ],
            "Resource": [
                "arn:aws:s3:::backup.user-customer.name/*",
                "arn:aws:s3:::backup.user-customer.name"
            ]
        }
    ]
 }
 ################
 - run "./mc admin policy add local backup.user-customer.name backup.user-customer.name.json"
 - run "./mc admin user add local backup.user-customer.name $NEWUSERPASSWORD"
   ( system says: Added user `backup.user-customer.name` successfully. )
 - run "./mc admin policy set local backup.user-customer.name user=backup.user-customer.name"
