快速开始¶
Rally是为Unix开发的，并已在Linux和MacOS上进行了很多测试。 Rally支持在Windows上运行的基准Elasticsearch集群，但是Rally本身需要安装在运行Unix的计算机上。
下载安装¶
安装Python 3.5+（包括pip3，git 1.9+）和对应的JDK以运行Elasticsearch。确保JAVA_HOME指向该JDK。然后运行以下命令，如有必要，可以使用sudo作为前缀：pip3 install esrally
如果您有任何麻烦或需要更详细的说明，请参阅详细的安装指南。
进行第一次测试¶
下面让我们进行第一次测试
esrally --distribution-version=6.5.3
这将下载Elasticsearch 6.5.3并对其运行Rally的默认track——the geonames（地名） track。比赛结束后，测试报告如下：
