ClickHouse Update

If ClickHouse was installed from deb packages, execute the following commands on the server:

$ sudo apt-get update
$ sudo apt-get install clickhouse-client clickhouse-server
$ sudo service clickhouse-server restart

If you installed ClickHouse using something other than the recommended deb packages, use the appropriate update method.

ClickHouse does not support a distributed update. The operation should be performed consecutively on each separate server. Do not update all the servers on a cluster simultaneously, or the cluster will be unavailable for some time.
