Redis is listening on all interface vs only on localhost

```
redis-ser 6938 diwu    4u  IPv6 0x6f12d8bdb02649f5      0t0  TCP *:6379 (LISTEN)
redis-ser 6938 diwu    5u  IPv4 0x6f12d8bdac8f562d      0t0  TCP *:6379 (LISTEN)
```

please secure this app so that by default, redis-server only binds to 127.0.0.1
