环境配置
注：这套环境配置为本文验证通过的环境配置及版本，避免踩坑请尽量按照环境配置里提到的配置及版本
Esrally客户端环境版本
Linux环境：centos7.9
Python：3.6.7
Pip：10.0.1 from pip (python 3.6)
Java：openjdk version 1.8.0_302 (build 1.8.0_302-b08)
Git：2.7.5
Esrally：1.4.1
Esrally客户端环境配置
内存：32G
硬盘：SSD云硬盘 100GB
CPU个数：1
CPU核心数：16
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。
部署
一：安装python3
1. 下载python3.6.7源码并解压
[root@VM-10-15-centos ~]# wget https://www.python.org/ftp/python/3.6.7/Python-3.6.7.tgz
Length: 22969142 (22M) [application/octet-stream]
Saving to: ‘Python-3.6.7.tgz.1’
100%[====================================================================================================================================================================================================================================>] 22,969,142 16.3MB/s in 1.3s
2021-10-19 17:06:33 (16.3 MB/s) - ‘Python-3.6.7.tgz.1’ saved [22969142/22969142]
[root@VM-10-15-centos ~]# tar -zxvf Python-3.6.7.tgz 2. 编译并安装
[root@VM-10-15-centos ~]# cd Python-3.6.7/
[root@VM-10-15-centos Python-3.6.7]# ./configure prefix=/usr/local/python3
[root@VM-10-15-centos Python-3.6.7]# make && make install3. 配置python3环境变量
[root@VM-10-15-centos Python-3.6.7]# echo 'export PYTHON3_HOME=/usr/local/python3' >> /etc/profile
[root@VM-10-15-centos Python-3.6.7]# echo 'export PATH=$PATH:$PYTHON3_HOME/bin' >> /etc/profile
[root@VM-10-15-centos Python-3.6.7]# tail -2 /etc/profile
export PYTHON3_HOME=/usr/local/python3
export PATH=$PATH:$PYTHON3_HOME/bin
[root@VM-10-15-centos Python-3.6.7]# source /etc/profile4. 验证
[root@VM-10-15-centos Python-3.6.7]# python3 -V
Python 3.6.7
[root@VM-10-15-centos Python-3.6.7]# pip3 -V
pip 10.0.1 from /usr/local/python3/lib/python3.6/site-packages/pip (python 3.6)二：安装JDK
1. 安装java
[root@VM-10-15-centos ~]# yum -y install java-1.8.0
Installed:
java-1.8.0-openjdk.x86_64 1:1.8.0.302.b08-0.el7_9
Complete!2. 配置java环境变量
[root@VM-10-15-centos esrally]# which java
/usr/bin/java
[root@VM-10-15-centos esrally]# ll /usr/bin/java
lrwxrwxrwx 1 root root 22 Oct 19 18:20 /usr/bin/java -> /etc/alternatives/java
[root@VM-10-15-centos esrally]# ll /etc/alternatives/java
lrwxrwxrwx 1 root root 73 Oct 19 18:20 /etc/alternatives/java -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.302.b08-0.el7_9.x86_64/jre/bin/java最终定位到java命令位于/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.302.b08-0.el7_9.x86_64/jre，所以将这个目录配置为JAVA_HOME
[root@VM-10-15-centos esrally]# echo 'export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.302.b08-0.el7_9.x86_64/jre' >> /etc/profile
[root@VM-10-15-centos esrally]# tail -1 /etc/profile
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.302.b08-0.el7_9.x86_64/jre
[root@VM-10-15-centos esrally]# source /etc/profile
[root@VM-10-15-centos esrally]# echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.302.b08-0.el7_9.x86_64/jre这个JAVA_HOME的配置是必要的，我们在使用esrally时会用到它。
三：安装esrally
1. 安装esrally
[root@VM-10-15-centos Python-3.6.7]# pip3 install esrally
Installing collected packages: docutils, urllib3, jmespath, six, python-dateutil, botocore, s3transfer, boto3, tabulate, psutil, thespian, MarkupSafe, Jinja2, elasticsearch, py-cpuinfo, zipp, typing-extensions, importlib-metadata, pyrsistent, attrs, jsonschema, certifi, esrally

[root@VM-10-15-centos Python-3.6.7]# esrally --version
Traceback (most recent call last):
File "/usr/local/python3/lib/python3.6/site-packages/pkg_resources/__init__.py", line 783, in resolve

Requirement.parse('urllib3<1.26,>=1.20; python_version >= "3.4"')urllib3要求<1.26并且>=1.20，我们来看一下当前urllib3的版本：
[root@VM-10-15-centos Python-3.6.7]# pip3 list | grep urllib3
urllib3 1.26.7 很显然，版本大于1.26了，那我们安装1.25吧：
[root@VM-10-15-centos Python-3.6.7]# pip3 install urllib3==1.25
Looking in indexes: http://mirrors.tencentyun.com/pypi/simple

Uninstalling urllib3-1.26.7:
Successfully uninstalled urllib3-1.26.7
Successfully installed urllib3-1.25再次执行esrally命令：
[root@VM-10-15-centos Python-3.6.7]# esrally --version
Traceback (most recent call last):
File "/usr/local/python3/lib/python3.6/site-packages/esrally/utils/io.py", line 18, in <module>
import bz2
File "/usr/local/python3/lib/python3.6/bz2.py", line 23, in <module>
from _bz2 import BZ2Compressor, BZ2Decompressor
ModuleNotFoundError: No module named '_bz2'又报了一个错，经过确认，这个问题是因为缺少bzip2的开发包，需要安装bzip2-devel之后再重新编译python。
安装bzip2开发包：
[root@VM-10-15-centos Python-3.6.7]# yum -y install bzip2-devel
Running transaction
Installing : bzip2-devel-1.0.6-13.el7.x86_64 1/1
Verifying : bzip2-devel-1.0.6-13.el7.x86_64 1/1
Installed:
bzip2-devel.x86_64 0:1.0.6-13.el7
Complete!重新编译安装python：
[root@VM-10-15-centos ~]# cd Python-3.6.7/
[root@VM-10-15-centos Python-3.6.7]# ./configure prefix=/usr/local/python3
[root@VM-10-15-centos Python-3.6.7]# make && make install再次执行esrally命令：
[root@VM-10-15-centos Python-3.6.7]# esrally --version
esrally 1.4.1配置esrally：
[root@VM-10-15-centos Python-3.6.7]# esrally configure
[root@VM-10-15-centos Python-3.6.7]# ll ~/.rally
total 16
drwxr-xr-x 6 root root 4096 Oct 20 11:04 benchmarks
-rw-r--r-- 1 root root 1354 Oct 19 19:25 logging.json
drwxr-xr-x 2 root root 4096 Oct 19 19:25 logs
-rw-r--r-- 1 root root 674 Oct 19 19:43 rally.ini执行此命令后会在当前用户根目录下生成 .rally 目录，至此，esrally就安装好了。
验证实例
我们根据官方文档来执行一个例子：
[root@VM-10-15-centos ~]# esrally --distribution-version=5.0.0

/ /_/ / __ `/ / / / / /

File "/usr/local/python3/lib/python3.6/ssl.py", line 101, in <module>
import _ssl # if we can't import it, let the error propagate
ModuleNotFoundError: No module named '_ssl'
验证失败，发现又报错了。经过确认，这个是由于缺少openssl开发包，需要安装openssl-devel之后再重新编译python。
1. 安装openssl开发包
[root@VM-10-15-centos ~]# yum -y install openssl-devel
Installed:
openssl-devel.x86_64 1:1.0.2k-22.el7_9
Dependency Installed:

-------------------------------
[INFO] FAILURE (took 8 seconds)

2. 安装Git命令
[root@VM-10-15-centos ~]# yum -y install git 4/4

[INFO] FAILURE (took 12 seconds)
--------------------------------这次报错信息变了，关键词信息为：
Please run:
git -C /root/.rally/benchmarks/tracks/default init那我们初始化一下目录吧：
[root@VM-10-15-centos ~]# git -C /root/.rally/benchmarks/tracks/default init
Unknown option: -C

[-p|--paginate|--no-pager] [--no-replace-objects] [--bare]
[--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
<command> [<args>]很显然，命令不兼容这个版本的git，通过了解，esrally需要安装git版本>=1.9，所以需要重新安装一下git。
这里我们需要通过编译的方式安装git，首先安装编译依赖：
[root@VM-10-15-centos ~]# yum -y install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker
Installed:

[root@VM-10-15-centos git-2.7.5]# which git
/usr/bin/git
[root@VM-10-15-centos git-2.7.5]# /usr/bin/git --version
git version 1.8.3.1没办法，那我们只能卸载掉操作系统系统的git命令了：
[root@VM-10-15-centos git-2.7.5]# rpm -qa | grep -w git
git-1.8.3.1-23.el7_8.x86_64
[root@VM-10-15-centos git-2.7.5]# rpm -e git-1.8.3.1-23.el7_8.x86_64

git is needed by (installed) gettext-devel-0.19.8.1-3.el7.x86_64报了个错，提示git命令有依赖，但是看了下面的两个包，都是我们需要用到的，所以只能强制卸载这个git了，加个--deps参数：
[root@VM-10-15-centos git-2.7.5]# rpm -e git-1.8.3.1-23.el7_8.x86_64 --nodeps
[root@VM-10-15-centos git-2.7.5]# git --version
-bash: /usr/bin/git: No such file or directory再次加载环境变量，让bash识别到我们的用户命令路径：
[root@VM-10-15-centos git-2.7.5]# source /etc/profile
[root@VM-10-15-centos git-2.7.5]# git --version
git version 2.7.5我们再次执行一下git目录初始化命令：
[root@VM-10-15-centos git-2.7.5]# git -C /root/.rally/benchmarks/tracks/default init
Reinitialized existing Git repository in /root/.rally/benchmarks/tracks/default/.git/发现已经可以执行了，那我们再运行一下官方的esrally例子，来确认一下esrally是否可用：
[root@VM-10-15-centos ~]# esrally --distribution-version=5.0.0

这里发现反复执行都无法下载elasitcsearch 5.0.0的包，那我们就换个6.0.0的版本吧：
[dy@VM-10-15-centos ~]$ esrally --distribution-version=6.0.0

压测过程中，CPU使用率还是比较高的：
最终输出了一份压测报告，但由于篇幅次数限制的缘故，无法贴上压测报告。

小结
至此，esrally的安装和实例验证就结束了。后续会使用这个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。
