Apache ignite是一个高性能内存计算框架，。本系列教程意在记录作者的使用和研究，同时希望给大家一些参考。

1.安装ignite

下载binary:

或者docker image:

2.启动一个节点

解压下载的文件。

C:\Users\temp\apache-ignite-2.9.1-bin>dir 驱动器 C 中的卷没有标签。 卷的序列号是 42E3-4287 C:\Users\temp\apache-ignite-2.9.1-bin 的目录2021/02/27  15:00    <DIR>          .2021/02/27  15:00    <DIR>          ..2020/12/09  14:33    <DIR>          benchmarks2020/12/09  14:33    <DIR>          bin2020/12/09  14:33    <DIR>          config2020/12/09  14:33    <DIR>          docs2020/12/09  14:33    <DIR>          examples2020/12/09  14:33    <DIR>          libs2020/12/09  14:33            17,858 LICENSE2020/12/09  14:33                57 MIGRATION_GUIDE.txt2020/12/09  14:33               421 NOTICE2020/12/09  14:33    <DIR>          platforms2020/12/09  14:33             3,343 README.txt2020/12/09  14:33            81,971 RELEASE_NOTES.txt2021/02/27  15:00    <DIR>          work               5 个文件        103,650 字节              10 个目录  9,489,559,552 可用字节

到apache-ignite-2.9.1-bin\bin，运行ignite.bat (Windows)或ignite.sh(Linux)。

看到[15:04:30] Ignite node started OK (id=41e9eabc)表示一个节点启动成功

[15:04:30] Topology snapshot显示ignite cluster的当前状态信息，包括ver号，server节点数，client节点数，运行状态，cpu数，offheap大小，heap大小等信息。

3.启动第二个节点

打开新的一个cmd line,到apache-ignite-2.9.1-bin\bin目录，运行ignite.bat。

现在第二个节点启动成功，自动加入到第一个节点的cluster。

可以看到ver号变成了2，server节点数变成了2。
