- Enable bucket lifecycle configuration using `mc`:

```sh
$ mc ilm import play/testbucket <<EOF
{
    "Rules": [
        {
            "Expiration": {
                "Date": "2020-01-01T00:00:00.000Z"
            },
            "ID": "OldPictures",
            "Filter": {
                "Prefix": "old/"
            },

notify_redis          publish bucket notifications to Redis datastores
```

### Accessing configuration

All configuration changes can be made using [`mc admin config` get/set/reset/export/import commands](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md).

#### List all config keys available

```
~ mc admin config set myminio/
```

`existing-objects` as a value to `--replicate` flag while adding or editing a replication rule.

Once existing object replication is enabled, all objects or object prefixes that satisfy the replication rules and were created prior to adding replication configuration OR while replication rules were disabled will be synced to the target cluster. Depending on the number of previously existing objects, the existing objects that are now eligible to be replicated will eventually be synced to the target...

```sh
firewall-cmd --get-active-zones
```

This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is `public`, use

```sh
firewall-cmd --zone=public --add-port=9000/tcp --permanent
```

Note that `permanent` makes sure the rules are persistent across firewall start, restart or reload. Finally reload the firewall for changes to take effect.
