clickhouse-client cannot login after enable listen host 0.0.0.0

问题

After installed the ClickHouse on Ubuntu 18.04.2 in Hyper-V VM, I use clickhouse-client inside the VM to connect, it works fine.

I used the browser in Host PC to open http://127.27.16.11:8123, it shows ERR_CONNECTION_REFUSED error. Then I edit the /etc/clickhouse-server/config.xml and uncomment the 0.0.0.0 and restart the clickhouse-server. I refresh the browser and it shows OK status.

However, when I use clickhouse-client inside the VM to connect server again, it prompts Connection refused. Is there any way to enable both local and remote connection?

Also tried to enable both IPv4 and IPv6 :: 0.0.0.0

ubuntu02:/$ clickhouse-client
ClickHouse client version 19.11.3.11 (official build).

回答1:

found the answer, I was too focus on those IP that I used is IPv4, indeed, Ubuntu enable IPv6 by default installation. It just simple uncomment this line

<listen_host>::</listen_host>

The problem is solved. Thanks Slesh for your kindly respond anyway.

You can to specify few host to listen. Try this configuration:

<!-- Listen specified host. use :: (wildcard IPv6 address), if you want to accept connections both with IPv4 and IPv6 from everywhere. -->
<listen_host>::</listen_host>
<!-- Default values - try listen localhost on ipv4 and ipv6: -->
<listen_host>::1</listen_host>
<listen_host>127.0.0.1</listen_host>
