This repository contains the Nebula Graph Console for Nebula Graph 2.0. Nebula Graph Console (Console for short) is a console for Nebula Graph. With Console, you can create a graph schema, import the demonstration basketballplayer
dataset, and retrieve data.
- Supports interactive and non-interactive mode.
- Supports viewing the history statements.
- Supports autocompletion.
- Supports multiple OS and architecture (We recommend Linux/AMD64).

Build Nebula Graph Console
To build Nebula Graph Console, make sure that you have installed Go.
NOTE: Go version provided with apt on ubuntu is usually "outdated".
Run the following command to examine if Go is installed on your machine.
$ go version
The version should be newer than 1.13.
Use Git to clone the source code of Nebula Graph Console to your host.
$ git clone https://github.com/vesoft-inc/nebula-console
Run the following command to build Nebula Graph Console.
$ cd nebula-console $ make
You can find a binary named
nebula-console
. -
Connect to Nebula Graph
To connect to your Nebula Graph services, use the following command.
$ ./nebula-console -addr <ip> -port <port> -u <username> -p <password> [-t 120] [-e "nGQL_statement" | -f filename.nGQL]
Option Description -h
Shows the help menu. -addr/-address
Sets the IP/HOST address of the graphd service. -P/-port
Sets the port number of the graphd service. -u/-user
Sets the username of your Nebula Graph account. See authentication. -p/-password
Sets the password of your Nebula Graph account. -t/-timeout
Sets an integer-type timeout threshold for the connection. The unit is second. The default value is 120. -e/-eval
Sets a string-type nGQL statement. The nGQL statement is executed once the connection succeeds. The connection stops after the result is returned. -f/-file
Sets the path of an nGQL file. The nGQL statements in the file are executed once the connection succeeds. You'll get the return messages and the connection stops then. -enable_ssl
Enable SSL when connecting to Nebula Graph -ssl_root_ca_path
Sets the path of the certification authority file -ssl_cert_path
Sets the path of the certificate file -ssl_private_key_path
Sets the path of the private key file -ssl_insecure_skip_verify
Controls whether a client verifies the server's certificate chain and host name E.g.,
$./nebula-console -addr=192.168.10.111 -port 9669 -u root -p nebula 2021/03/15 15:21:43 [INFO] connection pool is initialized successfully Welcome to Nebula Graph!
Check options for
./nebula-console -h
:-
try
./nebula-console
in interactive mode directly. -
And try
./nebula-console -e 'show hosts'
for the direct script mode. -
And try
./nebula-console -f demo.nGQL
for the script file mode.

-
Download the binaries on the Releases page
-
Add execute permissions to the binary
-
Connect to your Nebula Graph services:
$ ./<$YOUR_BINARY> -addr <ip> -port <port> -u <username> -p <password>
[-t 120] [-e "nGQL_statement" | -f filename.nGQL]
Create a container:
$ docker run --rm -ti --network nebula-docker-compose_nebula-net --entrypoint=/bin/sh vesoft/nebula-console:nightly
To connect to your Nebula Graph services, run the follow command in the container:
docker> nebula-console -u <user> -p <password> --address=<graphd> --port=9669
NOTE: The following commands are case insensitive.
- Export the result of the following statement to a csv file:
nebula> :csv a.csv
- Export the execution plan in graphviz format to a dot file when profiling a statement with format "dot" or "dot:struct":
nebula> :dot a.dot
nebula> PROFILE FORMAT="dot" GO FROM "Tony Parker" OVER like;
You can paste the content in the dot file to https://dreampuf.github.io/GraphvizOnline/
to show the execution plan.
- Load the demonstration
basketballplayer
dataset:
nebula> :play basketballplayer
Start loading dataset basketballplayer...
Load dataset succeeded!
- Repeat to execute a statement n times, the average execution time will also be printed:
nebula> :repeat 3
- Sleep for some seconds, it's just used in
:play basketballplayer
:
nebula> :sleep 3
- Exit the console
You can use :EXIT
or :QUIT
to disconnect from Nebula Graph. For convenience, nebula-console supports using these commands in lower case without the colon (":"), such as quit
.
nebula> :QUIT
Bye root!
nebula> :EXIT
Bye root!
nebula> quit
Bye root!
nebula> exit
Bye root!
