I change path in file elasticsearch.yml but it not working!

```auto
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: "C:\\env_thuanhieu\\data\\elasticsearch"
#
# Path to log files:
#
#path.logs: /path/to/logs
#

```

Welcome!

You need to uncomment the line I think. Instead of:

```
#path.data: "C:\\env_thuanhieu\\data\\elasticsearch"

```

Write:

```
path.data: "C:\\env_thuanhieu\\data\\elasticsearch"

```

@dadoonet

**Do i need move old file in data to the new data file**? (

because i have some trouble after that !  
I can't login into elasticsearch, I have error like

```auto
http client did not trust this server's certificate, closing connection Netty4HttpChannel{localAddress=/[0:0:0:0:0:0:0:1]:9200, remoteAddress=/[0:0:0:0:0:0:0:1]:51462}

```

```auto
Authentication of [elastic] was terminated by realm [reserved] - failed to authenticate user [elastic]

```

You did not say that you had existing data.

If you don't, I think you need to restart from scratch. If you did have existing data, Elasticsearch is not going to move that for you so yes I assume you need to do it first.
