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。
在前两篇的部署文档中，我们遇到了多个难解决的问题，并且一一解决了。所以这里，我们将所有坑都避开，出一个完整版避坑指南。
部署
一：安装Python3
1. 安装依赖
- 安装bzip2开发包
这里必须要安装，否则在执行esrally的时候会提示缺少_bz2。
[root@VM-10-15-centos ~]# 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!- 安装openssl开发包
这也是必装项，否则在执行esrally的时候会提示缺少_ssl。
[root@VM-10-15-centos ~]# yum -y install openssl-devel
Installed:
openssl-devel.x86_64 1:1.0.2k-22.el7_9
Dependency Installed:
keyutils-libs-devel.x86_64 0:1.5.8-3.el7 krb5-devel.x86_64 0:1.15.1-50.el7 libcom_err-devel.x86_64 0:1.42.9-19.el7 libkadm5.x86_64 0:1.15.1-50.el7 libselinux-devel.x86_64 0:2.5-15.el7 libsepol-devel.x86_64 0:2.5-10.el7 libverto-devel.x86_64 0:0.2.5-4.el7
pcre-devel.x86_64 0:8.32-17.el7
Dependency Updated:
openssl.x86_64 1:1.0.2k-22.el7_9 openssl-libs.x86_64 1:1.0.2k-22.el7_9

[root@VM-10-15-centos Python-3.8.7]# echo 'export PYTHON3_HOME=/usr/local/python3' >> /etc/profile
[root@VM-10-15-centos Python-3.8.7]# echo 'export PATH=$PATH:$PYTHON3_HOME/bin' >> /etc/profile
[root@VM-10-15-centos Python-3.8.7]# tail -2 /etc/profile
export PYTHON3_HOME=/usr/local/python3
export PATH=$PATH:$PYTHON3_HOME/bin
[root@VM-10-15-centos Python-3.8.7]# source /etc/profile5. 验证
[root@VM-10-15-centos Python-3.8.7]# python3 -V
Python 3.8.7
[root@VM-10-15-centos Python-3.8.7]# pip3 -V
pip 20.2.3 from /usr/local/python3/lib/python3.8/site-packages/pip (python 3.8)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/jreJAVA_HOME的配置是必要的，我们在使用esrally时会用到它。
三：安装Git
1. 安装编译依赖
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:
expat-devel.x86_64 0:2.1.0-12.el7 gettext-devel.x86_64 0:0.19.8.1-3.el7 perl-ExtUtils-MakeMaker.noarch 0:6.68-3.el7
Dependency Installed:
gdbm-devel.x86_64 0:1.10-8.el7 gettext-common-devel.noarch 0:0.19.8.1-3.el7 git.x86_64 0:1.8.3.1-23.el7_8 libdb-devel.x86_64 0:5.3.21-25.el7 perl-ExtUtils-Install.noarch 0:1.58-299.el7_9 perl-ExtUtils-Manifest.noarch 0:1.61-244.el7
perl-ExtUtils-ParseXS.noarch 1:3.18-3.el7 perl-Git.noarch 0:1.8.3.1-23.el7_8 perl-Test-Harness.noarch 0:3.28-3.el7 perl-devel.x86_64 4:5.16.3-299.el7_9 pyparsing.noarch 0:1.5.6-9.el7 systemtap-sdt-devel.x86_64 0:4.0-13.el7
Complete!2. 下载git源码
这里的--no-check-certificate参数一定要加上，否则在下载的时候会报Issued certificate has expired
[root@VM-10-15-centos ~]# wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.7.5.tar.gz --no-check-certificate
Saving to: ‘git-2.7.5.tar.gz’

[root@VM-10-15-centos ~]# tar -zxvf git-2.7.5.tar.gz
[root@VM-10-15-centos ~]# cd git-2.7.5/
[root@VM-10-15-centos git-2.7.5]# make prefix=/usr/local/git all
[root@VM-10-15-centos git-2.7.5]# make prefix=/usr/local/git install4. 卸载旧版git
卸载安装Git编译依赖时自动安装的低版本Git
[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 --nodeps4. 配置git环境变量：
[root@VM-10-15-centos git-2.7.5]# echo 'export GIT2_HOME=/usr/local/git' >> /etc/profile
[root@VM-10-15-centos git-2.7.5]# echo 'export PATH=$PATH:$GIT2_HOME/bin' >> /etc/profile
[root@VM-10-15-centos git-2.7.5]# tail -2 /etc/profile
export GIT2_HOME=/usr/local/git
export PATH=$PATH:$GIT2_HOME/bin
[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 2.7.5四：安装Esrally
1. 获取安装包
通过esrally在GitHub上的官方项目中来获取新版安装包：

2. 解压并安装
将安装包传至服务器上并解压：

esrally 2.3.0可以看到，esrally已经安装好了，版本为2.3.0。
小结
至此，esrally的安装就结束了。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。
