## 1. Standalone Deployment

To host multiple tenants on a single machine, run one MinIO Server per tenant with a dedicated HTTPS port, configuration, and data directory.

### 1.1 Host Multiple Tenants on a Single Drive

Use the following commands to host 3 tenants on a single drive:

```sh
minio server --address :9001 /data/tenant1

}

// Given a string of the form "host", "host:port", or "[ipv6::address]:port",
// return true if the string includes a port.
func hasPort(s string) bool { return strings.LastIndex(s, ":") > strings.LastIndex(s, "]") }

// removeEmptyPort strips the empty port in ":port" to ""
// as mandated by RFC 3986 Section 6.2.3.
func removeEmptyPort(host string) string {
	if hasPort(host) {
		return strings.TrimSuffix(host, ":")
	}

	Enable             bool      `json:"enable"`
	Format             string    `json:"format"`
	ConnectionString   string    `json:"connectionString"`
	Table              string    `json:"table"`
	Host               xnet.Host `json:"host"`     // default: localhost
	Port               string    `json:"port"`     // default: 5432
	Username           string    `json:"username"` // default: user running minio

mc alias set minio3 https://minio3.example.com:9000 adminuser adminpassword
```

or

```sh
export MC_HOST_minio1=https://adminuser:******@****.***
export MC_HOST_minio2=https://adminuser:******@****.***
export MC_HOST_minio3=https://adminuser:******@****.***
```

- Add site replication configuration with:

```sh

			// When we create this peer client, the grid connection is likely not yet initialized.
			if node.GridHost == "" {
				bugLogIf(context.Background(), fmt.Errorf("gridHost is empty for peer %s", node.Host), node.Host+":gridHost")
				return nil
			}
			gc := gridConn.Load()
			if gc != nil {
				return gc
			}
			gm := globalGrid.Load()
			if gm == nil {
				return nil
			}

		host        string
