# How do I connect to my ClickHouse server?

https://www.seturack.com/en/knowledgebase/article/how-do-i-connect-to-my-clickhouse-server

1. In the panel, open **My servers** and click your server.
2. On the **Overview** tab, wait for the **App** row to say "ClickHouse is ready". The page refreshes itself.
3. Copy the details from the **Connection address**, **Login** and **Password** rows.

## Connecting

Try it over HTTP:

`curl -u default:PASSWORD 'http://IP:8123/?query=SELECT%201'`

Connect with the native client on port **9000**: `clickhouse-client --host IP --password PASSWORD`

## Security

- Database port **8123** is open to the internet. To let only your own servers connect, limit it in the firewall: `ufw delete allow 8123/tcp`, then `ufw allow from YOUR_IP to any port 8123`.
- Port **9000** is open too, so limit it the same way. Connections come without TLS.
- If the server has less than 16 GB, installation turns on the low memory settings the official docs recommend: one query thread, small caches, system logs off. When you resize, delete `/etc/clickhouse-server/config.d/seturack-dusuk-bellek.xml` and `/etc/clickhouse-server/users.d/seturack-dusuk-bellek.xml` and run `systemctl restart clickhouse-server`.

**No server yet?** [Order a server with ClickHouse installed](https://www.seturack.com/en/clickhouse-vps): you choose the size and pay for what you choose.
