一、前言

本次BenchmarkSQL 压测openGauss仅作为学习使用压测工具测试tpcc为目的,并不代表数据库性能如本次压测所得数据。实际生产性能压测,还需结合服务器软硬件配置、数据库性能参数调优、BenchmarkSQL 配置文件参数相结合,是一个复杂的过程。

1.1 BenchmarkSQL 工具介绍

BenchmarkSQL 是一款经典的开源数据库测试工具,其内含了TPC-C测试脚本,可同时支持 Oracle、MySQL、PostGreSQL、SQL Server以及一些国产数据库的基准测试,应用其对数据库进行 TPC-C 标准测试,可模拟多种事务处理:如新订单、支付操作、订单状态查询、发货、库存状态查询等,从而获得TpmC 值。截止到2023年8月,最新的BenchmarkSQL 版本是5.0。

1.2 数据库信息介绍

本次压测所使用的openGauss数据库是一套两节点主备集群,数据库版本为5.0.0。在进行压测前假设已创建了测试数据库和用户,设置了用户权限,并为数据库配置了白名单,创建数据库、用户、设置权限及设置白名单基本操作如下。

-- 数据库服务器,omm用户操作
-- 连接数据库
[omm@opengauss-db2 ~]$ gsql -d gaussdb -p 26000 

-- 创建数据库用户
gaussdb=# CREATE USER openuser WITH SYSADMIN password "Openuser@123";

-- 分配用户权限
gaussdb=# GRANT ALL PRIVILEGES TO openuser;

-- 设置白名单,运行程序从192.168.73.21 访问数据库
[omm@opengauss-db2 ~]$ gs_guc reload -N all -I all -h "host  gaussdb  openuser  192.168.73.21/32  sha256"

三、环境准备

3.1 安装软件依赖包

部署BenchmarkSQL需要系统安装一些依赖包,如果服务器可联网,可通过yum直接安装,如果无法联网,可在服务器上配置本地YUM源,通过本地YUM安装软件依赖包。

-- BenchmarkSQL 服务器,root用户操作
-- yum 安装软件依赖包
[root@opensource-db ~]# yum install gcc glibc-headers gcc-c++ gcc-gfortran readline-devel  libXt-devel pcre-devel libcurl libcurl-devel \
java-11-openjdk  ant ncurses ncurses-devel autoconf automake zlib zlib-devel bzip2 bzip2-devel xz-devel -y 

-- 检查是否已安装
rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" | grep -E "gcc|glibc-headers|gcc-c++|gcc-gfortran|readline-devel|libXt-devel|pcre-devel|libcurl libcurl-devel|java-11-openjdk|ant|ncurses|ncurses-devel|autoconf|automake|zlib|zlib-devel|bzip2|bzip2-devel|xz-devel"

3.2 创建用户

BenchmarkSQL选择部署在非root用户omm用户下。

[root@opensource-db ~]# /usr/sbin/groupadd -g 1000 dbgrp
[root@opensource-db ~]# /usr/sbin/useradd -u 1000 -g dbgrp omm
[root@opensource-db ~]# echo "omm123" | passwd --stdin omm

3.3 安装部署BenchmarkSQL

3.3.1 下载BenchmarkSQL

登录https://sourceforge.net/projects/benchmarksql/files/网站下载最新版BenchmarkSQL 5.0,将下载的benchmarksql-5.0.zip上传至服务器omm用户/home/omm目录下并解压。

3.7 配置互信

使用BenchmarkSQL压测,要配置BenchmarkSQL服务器到openGauss数据库omm用户的互信,配置方法如下。

-- BenchmarkSQL 服务器,omm用户操作

Generating public/private rsa key pair.
Enter file in which to save the key (/home/omm/.ssh/id_rsa):  // 按回车
Created directory '/home/omm/.ssh'.
Enter passphrase (empty for no passphrase):   // 按回车
Enter same passphrase again:   // 按回车
Your identification has been saved in /home/omm/.ssh/id_rsa.
Your public key has been saved in /home/omm/.ssh/id_rsa.pub.
The key fingerprint is:

五、生成测试报告

5.1 生成测试报告

通过执行BenchmarkSQL工具中generateReport.sh脚本,用来生成测试报告。

-- BenchmarkSQL 服务器,omm用户操作
[omm@opensource-db ~]$ cd /home/omm/benchmarksql-5.0/run
[antdb@opensource-db run]$ ./generateReport.sh my_result_2023-08-03_131532
Generating my_result_2023-08-03_131532/tpm_nopm.png ... OK
Generating my_result_2023-08-03_131532/latency.png ... OK

Generating my_result_2023-08-03_131532/dirty_buffers.png ... OK

Generating my_result_2023-08-03_131532/blk_sda_kbps.png ... OK
Generating my_result_2023-08-03_131532/net_ens33_iops.png ... OK
Generating my_result_2023-08-03_131532/net_ens33_kbps.png ... OK
Generating my_result_2023-08-03_131532/report.html ... OK

5.2 查看测试报告

打包并下载my_result_2023-08-03_131532目录文件,里面包含了生成的测试报告,其中report.html文件已html格式生成测试报告。

报告里包含了数据库、磁盘、网卡压测等信息。

六、附录

6.1 IOError: [Errno 2] No such file or directory

如果props配置文件数据库网卡名称错误,在执行压测时会报如下错误:

Traceback (most recent call last):
  File "<stdin>", line 211, in <module>
  File "<stdin>", line 39, in main
  File "<stdin>", line 186, in initNetDevice
IOError: [Errno 2] No such file or directory: '/sys/class/net/eth0/statistics/rx_packets'

6.2 ValueError: can’t have unbufferd text I/O

如果部署BenchmarkSQL的服务器没有部署python2,而部署了python3,会导致os_collector_linux.py采集报错,无法采集到数据库操作系统信息,因为os_collector_linux.py脚本部分内容不兼容python3,会报如下错误:

Traceback (most recent call last):

  File "<stdin>", line 65, in main

6.3 ant无法编译BenchmarkSQL

有时会遇到ant无法编译BenchmarkSQL的问题,遇到如下报错:

Error: Could not find or load main class org.apache.tools.ant.launch.Launcher
Caused by: java.lang.ClassNotFoundException: org.apache.tools.ant.launch.Launcher

解决办法是,要配置环境JAVA_HOME和CLASSPATH环境变量,如下所示:

-- BenchmarkSQL服务器,omm用户操作
-- 编辑 .bash_profile文件,添加如下内容
export JAVA_HOME=/usr/java/jdk-11
export CLASSPATH=.:${JAVA_HOME}/lib:/usr/share/ant/lib/ant-launcher.jar
-- 生效 .bash_profile文件

此时就可以使用ant正常编译BenchmarkSQL了。
