背景
在大数据时代的今天，业务量越来越大，每天动辄都会产生上百GB、上TB的数据，所以拥有一个性能强劲的Elasticsearch集群就显得尤为重要。我们需要模拟大量网络日志、用户行为日志的读写动作，衡量各性能的指标，找出集群瓶颈所在，以确认我们需要怎样的硬件配置以及业务优化，才能满足现有的业务量，这就是我们在业务上线前所必要做的。
在上一篇中，我们遇到了多个难解决的问题，并且一一解决了。但殊不知，坑是填不完的。
压测
esrally 相关术语及参数
Rally 是汽车拉力赛的意思，所以关于它里面术语也是跟汽车的拉力赛有关。
- track: 即赛道的意思，这里指压测用到的样本数据和压测策略，使用
esrally list tracks列出。rally 自带的 track 可在 https://github.com/elastic/rally-tracks 中查看，每个 track 的文件名中都存在 README.md 对压测的数据类型和参数做了详细的说明。如果没有指定 track， 则默认使用 geonames track 进行测试； - target-hosts：即远程elasticsearch的ip和端口，以ip:port的形式指定；
- pipeline: 指一个压测流程，可以通过
esrally list pipeline查看，其中有一个benchmark-only的流程，就是将 es 的管理交给用户来操作，rally 只用来做压测，如果你想针对已有的 es 进行压测，则使用该模式； - track-params：对默认的压测参数进行覆盖；
- user-tag：本次压测的 tag 标记；
- client-options：指定一些客户端连接选项，比如用户名和密码。
[dy@VM-10-15-centos ~]$ esrally \

> --target-hosts=10.0.10.4:9200 \

************************************************************************
************** WARNING: A dark dungeon lies ahead of you **************
************************************************************************
Rally does not have control over the configuration of the benchmarked
Elasticsearch cluster.
Be aware that results may be misleading due to problems with the setup.
Rally is also not able to gather lots of metrics at all (like CPU usage
of the benchmarked cluster) or may even produce misleading metrics (like
the index size).

* Check the log files in /home/dy/.rally/logs for errors.
* Read the documentation at https://esrally.readthedocs.io/en/1.4.1/
* Ask a question on the forum at https://discuss.elastic.co/c/elasticsearch/rally

[INFO] FAILURE (took 4335 seconds)
----------------------------------果不其然，坑是填不完的，还是报错了。报错信息为：
Cannot execute [user-defined context-manager enabled runner for [query]]. Provided parameters are: ['index', 'type', 'cache', 'request-params', 'body']. Error: ['total'].不支持total这个参数，那看来是版本问题了，那我们升级一下esrally吧。
首先我们看下esrally有哪些版本：
[root@VM-10-15-centos ~]# esrally --version
esrally 1.4.1
[root@VM-10-15-centos ~]# pip3 list | grep esrally
esrally 1.4.1
[root@VM-10-15-centos ~]# pip3 install esrally==
Looking in indexes: http://mirrors.tencentyun.com/pypi/simple
Collecting esrally==
Could not find a version that satisfies the requirement esrally== (from versions: 0.2.0, 0.2.1, 0.3.0, 0.3.1, 0.3.2, 0.3.3, 0.4.0, 0.4.1, 0.4.2, 0.4.3, 0.4.4, 0.4.5, 0.4.6, 0.4.7, 0.4.8, 0.5.0, 0.5.1, 0.5.2, 0.5.3, 0.6.0, 0.6.1, 0.6.2, 0.7.0, 0.7.1, 0.7.2, 0.7.3, 0.7.4, 0.8.0, 0.8.1, 0.9.0, 0.9.1, 0.9.2, 0.9.3, 0.9.4, 0.10.0, 0.10.1, 0.11.0, 1.0.0, 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.1.0, 1.2.1, 1.3.0, 1.4.0, 1.4.1)
No matching distribution found for esrally==在pip源里，1.4.1已经是最新版本了，看来没法通过pip来安装了。
重新安装Esrally
1. 获取安装包
当下，只能通过esrally在GitHub上的官方项目中来获取新版安装包了。
https://github.com/elastic/rally/releases/

2. 解压并安装
将安装包传至服务器上并解压：

重新尝试压测
执行压测：
[dy@VM-10-15-centos ~]$ esrally \

通过了解，新版esrally需要加上race参数，指定需要做的是压测：
[dy@VM-10-15-centos ~]$ esrally race \

小结
至此，esrally的安装和压测验证就结束了。后续会继续使用这个esrally客户端，对当前Elasticsearch市面上几大主流的配置机型进行实际压测，届时会继续分享给大家。
小彩蛋
新版本的esrally，在压测中途发起Ctrl+C信号，esrally会返回一个骷髅头的画面，一开始还把我吓一跳 ☺
