在安卓平台运行

从 v0.4.0 开始，GreptimeDB 支持在采用了 ARM64 CPU 和 Android API 23 版本以上的安卓平台运行。

安装终端模拟器

您可以从 GitHub release 页面 下载 Termux 终端模拟器 来运行 GreptimeDB.

下载 GreptimeDB 的二进制

请执行以下命令来下载安卓平台的 GreptimeDB 二进制：

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

如果下载成功，以上命令将输出：

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

创建 GreptimeDB 的配置文件

您可以通过以下命令来创建一个最小化的配置文件以允许从局域网访问 GreptimeDB：

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

从命令行启动 GreptimeDB

bash

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

从局域网连接运行在安卓设备上的 GreptimeDB

您可以通过ifconfig来获取您所使用的的安卓设备的网络地址。

在启动 GreptimeDB 后，您可以从局域网内安装了 MySQL 客户端的设备上通过 MySQL 协议访问 GreptimeDB。

bash

1. mysql -h <ANDROID_DEVICE_IP_ADDR> -P 4002

连接成功后，您可以像在任何其他平台一样使用运行在安卓设备上的 GreptimeDB！
