Run on Android Platforms

Since v0.4.0, GreptimeDB supports running on Android platforms with ARM64 CPU and Android API level >= 23.

Install terminal emulator on Android

You can install Termux from GitHub release page.

Download GreptimeDB Android binary.

bash

1. curl -sOL https://github.com/GreptimeTeam/greptimedb/releases/download/v0.4.0/greptime-android-arm64-v0.4.0.tar.gz
2. tar zxvf ./greptime-android-arm64-v0.4.0.tar.gz
3. ./greptime -V

If binary’s downloaded correctly, the command is expected to print:

1. greptimedb
2. branch: HEAD
3. commit: c9c2b3c91f273ff605782dbb8a4873e511dfea10
4. dirty: false
5. version: 0.4.0

Create GreptimeDB configuration file

You can create a minimal configuration file that allows access from local network.

bash

1. DATA_DIR="$(pwd)/greptimedb-data"
2. mkdir -p ${DATA_DIR}

4. cat <<EOF > ./config.toml
5. [http]
6. addr = "0.0.0.0:4000"

8. [grpc]
9. addr = "0.0.0.0:4001"

11. [mysql]
12. addr = "0.0.0.0:4002"

14. [storage]
15. data_home = "${DATA_DIR}"
16. type = "File"
17. EOF

Start GreptimeDB from command line

bash

1. ./greptime --log-dir=$(pwd)/logs standalone start -c ./config.toml

Connect to GreptimeDB running on Android

You can find the IP address of your Android device from system settings or ifconfig.

You can now connect to the GreptimeDB instance running on Android from another device with MySQL client installed.

bash

1. mysql -h <ANDROID_DEVICE_IP_ADDR> -P 4002

And play like on any other platforms!
