# ClickHouse Update {#clickhouse-update}
|
|
|
|
If ClickHouse was installed from deb packages, execute the following commands on the server:
|
|
|
|
``` bash
|
|
$ 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.
