PostgreSQL压测工具sqlbench

sqlbench是阿里云数据库内核团队的mark wong大大开源的一款TPC-C测试软件，完全遵循TPC-C标准编写，关键它是纯C的，效率非常高，并且在遵循TPC-C的标准同时对请求模型进行优化。
https://github.com/swida/sqlbench

环境介绍：

RHEL 7.5
PG 11.5

环境准备：

PG数据库初始化完成(Port:5435)，创建压测用户(sqlbench)、数据库(sqlbench)。

[postgres@rhel75 ~]$createuser -s sqlbench
[postgres@rhel75 ~]$createdb sqlbench

sqlbench安装，通过git进行安装，需要连接外网，可下载后上传的服务器进行解压：
--提前安装相关软件
[root@rhel75 ~]# yum -y install automake.noarch autoconf-2.69-11.el7.noarch

[root@rhel75 soft]# git clone https://github.com/swida/sqlbench

查看支持的配置选项,如--with-postgresql=yes会导致Command pg_config not found问题
[root@rhel75 sqlbench]# ./configure --help
[root@rhel75 sqlbench]# ./configure --with-postgresql=/usr/local/pgsql
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /usr/bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
......
config.status: creating config.h
config.status: executing depfiles commands

make && make install
注：如不执行make install，可以进入以下路径执行,本次实验环境通过make install进行测试
[postgres@rhel75 core]$pwd
/soft/sqlbench/src/core

sqlbench支持命令参数
[postgres@rhel75 ~]$sqlbench --help
usage: sqlbench -t -c # -w # -l # [-r #] [-s #] [-e #] [-o p] [-z]
-t
        available: postgresql
        for postgresql: --dbname= --host= --port= --user=
-c #
        number of database connections
-w #
        warehouse cardinality, default 1
-l #
        the duration of the run in seconds

-r #
        the duration of ramp up in seconds
-s #
        lower warehouse id, default 1
-e #
        upper warehouse id, default
-o p
        output directory of log files, default current directory
-z
        perform database integrity check
......
--sqlapi
        run test using sql interface, available:
        simple      default, just send sql statement to database
        extended    use extended (prepare/bind/execute) protocol, better than simple
        storeproc   use store procedure
