See Release Notes for what's new in the latest release, v22.1.22. To upgrade to this release from an older version, see Cluster Upgrade.
To deploy a free CockroachDB Cloud cluster instead of running CockroachDB yourself, see the Quickstart.
Install options
Use one of the options below to install CockroachDB.
Download the binary
The CockroachDB binary for Linux requires glibc
, libncurses
, and tzdata
, which are found by default on nearly all Linux distributions, with Alpine as the notable exception.
-
Download the CockroachDB archive for Linux and the supporting libraries that are used to provide spatial features, and copy the binary into your
PATH
so you can execute cockroach commands from any shell:$ curl https://binaries.cockroachdb.com/cockroach-v22.1.22.linux-amd64.tgz | tar -xz && sudo cp -i cockroach-v22.1.22.linux-amd64/cockroach /usr/local/bin/
If you get a permissions error, prefix the command with
sudo
. -
CockroachDB uses custom-built versions of the GEOS libraries. Copy these libraries to one of the locations where CockroachDB expects to find them.
By default, CockroachDB looks for external libraries in
/usr/local/lib/cockroach
or alib
subdirectory of the CockroachDB binary's current directory. If you place these libraries in another location, you must pass the location in the--spatial-libs
flag tocockroach start
. The instructions below assume the/usr/local/lib/cockroach
location.- Create the directory where the external libraries will be stored:
mkdir -p /usr/local/lib/cockroach
- Copy the library files to the directory:
cp -i cockroach-v22.1.22.linux-amd64/lib/libgeos.so /usr/local/lib/cockroach/
cp -i cockroach-v22.1.22.linux-amd64/lib/libgeos_c.so /usr/local/lib/cockroach/
If you get a permissions error, prefix the command with
sudo
.
- Create the directory where the external libraries will be stored:
Verify that CockroachDB can execute spatial queries.
Make sure the
cockroach
binary you just installed is the one that runs when you typecockroach
in your shell:which cockroach
/usr/local/bin/cockroach
Start a temporary, in-memory cluster using
cockroach demo
:cockroach demo
In the demo cluster's interactive SQL shell, run the following command to test that the spatial libraries have loaded properly:
> SELECT ST_IsValid(ST_MakePoint(1,2));
You should see the following output:
st_isvalid -------------- true (1 row)
If your
cockroach
binary is not properly accessing the dynamically linked C libraries in/usr/local/lib/cockroach
, it will output an error message like the one below.ERROR: st_isvalid(): geos: error during GEOS init: geos: cannot load GEOS from dir "/usr/local/lib/cockroach": failed to execute dlopen Failed running "sql"

Keep up-to-date with CockroachDB releases and best practices:
If you plan to use CockroachDB's spatial features, you must complete the following steps. Otherwise, your installation is now complete.
Use Kubernetes
To orchestrate CockroachDB using Kubernetes, either with configuration files or the Helm package manager, use the following tutorials:
Use Docker
-
Install Docker for Linux. Please carefully check that you meet all prerequisites.
-
Confirm that the Docker daemon is running in the background:
$ docker version
If you do not see the server listed, start the Docker daemon.
Note:On Linux, Docker needs sudo privileges. -
Pull the image for the v22.1.22 release of CockroachDB from Docker Hub:
$ sudo docker pull cockroachdb/cockroach:v22.1.22
-
Keep up-to-date with CockroachDB releases and best practices:
Build from Source
See the public wiki for guidance.
