按照官網的步驟來，一步一個坑，浪費了我一天的時間！多數是因為國内的網絡，下載下傳和拉取速度太慢，導緻安裝失敗。是以寫了這個文章，來記錄我成功安裝的案例，希望可以幫到想用esrally做基準測試的人！
網上也有文章不過都過時了！官網呢，又不适合中國網絡情況的使用。我甚至嚴重懷疑，官網的步驟，他們有沒有執行一遍試試。因為用哪些指令肯定會遇到問題。比如：
sudo yum install git
我不相信這條指令，能幫我們下載下傳新版本的git！
注意目前esrally最新版本是 2.5.0！
官網位址（英文的最新版）：Quickstart — Rally 2.5.0 documentation
中文文檔（0.9版本的）：安裝 — Rally 0.9.0 文檔
準備環境-需要的環境介紹
我在看文檔的時候，其實蠻想知道我為什麼要安裝這些東西，以及不安裝行不行，我需要安裝什麼版本的。我在看着官網折騰這個的時候浪費了挺多時間，是以特地寫一篇部落格來帶大家避坑！
作業系統 centos7，我是在centos7下安裝的，其它版本，作業系統不适用，其它版本我沒有驗證能否成功。esrally隻能運作在linux下！
安裝過程需要網絡環境。即使有網絡，在裝一些東西的時候依舊有很多問題，是以我在安裝一些東西的時候，也會用安裝包安裝，來減少問題的出現。
另外說一句，esrally文檔是寫給外國人的，因為一些網絡環境我們不具備，是以根據文檔操作，一大堆問題。
想要運作esrally必備的工具
- python3.8以上版本，我看官網的例子是用python3.8.10的版本。為了減少問題，我也用python3.8.10。說一下為什麼要用它，因為esrally是用python寫的，安裝也用到了pip3。這些都屬于必備的！
- git，版本1.9及以上版本。用git是因為es用到的資料都放在了網上，用到的測試用例也放在git上，是以需要我們在用的時候拉取。這個也是必須的，沒有不行！
- JDK。用這個是因為，esrally支援自動建構es叢集，就是幫你搭建叢集。es低版本（7版本之前）并沒有内嵌JDK，是以這些版本需要JDK，并配置好環境。如果你是自建叢集，對已有的叢集進行測試，那就不需要JDK了。如果需要它幫你搭建叢集，你就需要将JDK環境配置好。
- esrally，es基準測試的主角。
如何在linux centos下安裝python環境
這篇文章是我在用esrally的時候寫的，我跟着官網做的時候遇到很多坑，主要是浪費了時間，實在沒必要。我的這個方案更簡單！請看我這篇文章：
centos下編譯安裝各個版本的python_水的精神的部落格
如何更新git，或者說安裝git
centos7預設安裝了git，遺憾的是它的版本是1.8的。也就是低于官網要求的1.9版本。是以需要更新。在網上找文檔折騰的半天，都不靠譜。是以建議看我這篇文章（特簡單，三條指令）：
Linux centos下三條指令安裝更新git_水的精神的部落格
如何安裝JDK
下載下傳安裝jdk13
https://www.oracle.com/java/technologies/javase-jdk13-downloads.html 複制
下載下傳，上傳到伺服器上。
然後rpm安裝
rpm -ivh jdk-13.0.2_linux-x64_bin.rpm 配置環境變量，在 /etc/profile檔案的末尾加入以下内容
export JAVA_HOME=/usr/java/jdk-13.0.2
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar 并執行下列指令使環境變量生效
source /etc/profile 安裝esrally
官網給的操作是使用一條指令安裝，開起來很簡單：
pip3 install esrally 但是我執行不成功。可能我對python不是很熟悉的原因把。我用的其它方式來安裝的（離線安裝 esrally 是最靠譜的，解決拉取問題！我在嘗試上邊的指令的時候，遇到了一堆問題。不想解決了！是以用離線的方式來安裝它）：
- 安裝上面文檔提到的所有依賴包
- 下載下傳最新釋出的離線包 ，并将它拷貝到目标機器。
- 解壓安裝包
tar -xzf esrally-dist-*.tar.gz
- 執行安裝腳本
sudo ./esrally-dist-*/install.sh
在執行第四條的時候，還是遇到了問題（我把遇到幾個問題貼出來，希望可以幫到你們）：
執行 ./install.sh 第一個問題：
ERROR: Could not find a version that satisfies the requirement py-cpuinfo==7.0.0 (from esrally) (from versions: 7.0.0)
ERROR: No matching distribution found for py-cpuinfo==7.0.0
解決指令：
pip3 install py-cpuinfo -i https://pypi.tuna.tsinghua.edu.cn/simple/ --trusted-host pypi.tuna.tsinghua.edu.cn 執行 ./install.sh 第二個問題（python pip相關的問題）：
問題
WARNING: You are using pip version 21.1.1; however, version 22.1.2 is available.
You should consider upgrading via the '/usr/local/python38/bin/python3.8 -m pip install --upgrade pip' command.
解決指令：
python3 -m pip install --upgrade pip -i https://pypi.tuna.tsinghua.edu.cn/simple/ --trusted-host pypi.tuna.tsinghua.edu.cn 第三個問題：
解決問題：
pip3 install --upgrade setuptools -i https://pypi.tuna.tsinghua.edu.cn/simple/ --trusted-host pypi.tuna.tsinghua.edu.cn 以上三個問題解決完以後，esrally已經可以成功安裝了！
嘗試運作一下，因為我已經安裝過了es叢集。是以已經可以使用了！
