Mac上安装sysbench测试工具

brew install sysbench

sysbench能支持哪些性能指标测试

sysbench支持以下几种测试模式：

1、CPU运算性能
2、磁盘IO性能
3、调度程序性能
4、内存分配及传输速度
5、POSIX线程性能
6、数据库性能(OLTP基准测试)
目前sysbench主要支持 mysql,drizzle,pgsql,oracle 等几种数据库。

磁盘Io测试

第一步准备阶段，生成测试用到的数据文件，生成的数据文件至少要比内存大

//创建测试文件，后续run操作会读写这个文件 这里文件大小为10G
sysbench --test=fileio --file-total-size=10G prepare

ARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.

文件的读写模式如下

• seqwr 顺序写入
• seqrewr 顺序重写
• seqrd 顺序读取

第二步 测试写入数据

//执行混合随机测试//随机写入时间为300秒
sysbench --test=fileio --file-total-size=10G --file-test-mode=rndrw --time=300 --max-requests=0 run

sysbench --test=fileio --file-total-size=10G cleanup

数据库性能(OLTP基准测试)

查看一下：

0.5版本之后就取消了—test=oltp的命令，改用直接调用脚本的方式

如何查看脚本的参数和语法

第一步准备数据库

mysqladmin create test

第二步 准备测试数据

//准备十万条测试数据的量

第三步测试

进行插入性能测试

//插入10万条数据，8个线程执行，每10秒中报告一次 
sysbench --test=/usr/local/Cellar/sysbench/1.0.17/share/sysbench/oltp_insert.lua --table-size=100000 --mysql-host=k8s-n1 --mysql-port=3307 --mysql-user=root --mysql-password=123456 --mysql-db=test --threads=8 --max-requests=0 --report-interval=10  --time=300 run

结果

详细介绍

SysBench 使用指南

更新时间：2018-09-29 16:44:06

本页目录

• 安装
• 使用简介

DRDS 性能测试使用 SysBench 作为压测工具，本文介绍 SysBench 的使用方法。

安装

测试使用的是 SysBench 0.5 版本，安装方法如下：

git clone https://github.com/akopytov/sysbench.gitgit checkout 0.5yum -y install make automake libtool pkgconfig libaio-develyum -y install mariadb-devel./autogen.sh./configuremake -jmake install

注意：以上是在压测 ECS 上的安装方法，如果需要安装到其他操作系统，参考 SysBench 官方文档。

安装完毕后，所有自带压测脚本都在 /usr/local/share/sysbench 目录下，DRDS 性能测试将使用该目录下的脚本。除此之外，也可以在源码目录 sysbench/sysbench/tests/db 下找到对应的压测脚本。

使用简介

常用测试模型

SysBench 通过脚本定义了若干常用的压测模型，以下简单介绍几个常用模型：

表结构

对 DRDS 进行测试时，对 SysBench 的测试表稍作改造，将其修改为分库分表的形式，测试表的建表语句如下：

CREATE TABLE `sbtest1` (  `id` int(10) unsigned NOT NULL,  `k` int(10) unsigned NOT NULL DEFAULT '0',  `c` char(120) NOT NULL DEFAULT '',  `pad` char(60) NOT NULL DEFAULT '',  KEY `xid` (`id`),  KEY `k_1` (`k`)) dbpartition by hash(`id`) tbpartition by hash(`id`) tbpartitions 4

以上建表语句中，分库分表数可自行调整，该表会在准备数据阶段自动生成，无需手动创建。

测试命令及参数

使用 SysBench 进行压测，通常分为三个步骤：

• prepare，准备数据
• run，运行测试模型
• cleanup，清理测试数据

通常仅需准备一次数据，在此数据基础上测试各种模型即可。

常用参数

SysBench 中常用的参数如下：

• --oltp-tables-count=1：表数量
• --oltp-table-size=10000000：每个表产生的记录行数
• --oltp-read-only=off：是否生成只读SQL，默认 off，如果设置为 on，则 oltp 模型不会生成 update, delete, insert 的 SQL 语句
• --oltp-skip-trx=[on|off]：省略 BEGIN / COMMIT 语句。默认是 off
• --rand-init=on：是否随机初始化数据，如果不随机化那么初始好的数据每行内容除了主键不同外其他完全相同
• --num-threads=12： 并发线程数，可以理解为模拟的客户端并发连接数
• --report-interval=10：表示每 10s 输出一次性能数据
• --max-requests=0：压力测试产生请求的总数，如果以下面的 max-time 来记，这个值设为 0 即可
• --max-time=120：测试的持续时间
• --oltp_auto_inc=off：id 是否为自增列
• --oltp_secondary=on：将 id 设置为非主键防止主键冲突
• --oltp_range_size=5: 连续取值 5 个，必定走到 5 个分片
• --mysql_table_options=‘dbpartition by hash(id) tbpartition by hash(id) tbpartitions 2‘：DRDS 支持拆分表，在建表的时候需要指定拆分方式

示例命令

以下是示例命令，供参考：

准备数据：

sysbench --test='/usr/local/share/sysbench/oltp.lua' --oltp_tables_count=1 --report-interval=10 --oltp-table-size=10000000  --mysql-user=*** --mysql-password=*** --mysql-table-engine=innodb  --rand-init=on  --mysql-host=**** --mysql-port=*** --mysql-db=*** --max-time=300 --max-requests=0   --oltp_skip_trx=on --oltp_auto_inc=off  --oltp_secondary=on --oltp_range_size=5 --mysql_table_options='dbpartition by hash(`id`) tbpartition by hash(`id`) tbpartitions 2' --num-threads=200   prepare

执行测试

sysbench --test='/usr/local/share/sysbench/oltp.lua' --oltp_tables_count=1 --report-interval=10 --oltp-table-size=10000000  --mysql-user=*** --mysql-password=*** --mysql-table-engine=innodb  --rand-init=on  --mysql-host=**** --mysql-port=*** --mysql-db=*** --max-time=300 --max-requests=0   --oltp_skip_trx=on --oltp_auto_inc=off --oltp_secondary --oltp_range_size=5 --mysql_table_options='dbpartition by hash(`id`) tbpartition by hash(`id`) tbpartitions 2' --num-threads=200 run

清理环境

sysbench --test='/usr/local/share/sysbench/oltp.lua' --oltp_tables_count=1 --report-interval=10 --oltp-table-size=10000000  --mysql-user=*** --mysql-password=*** --mysql-table-engine=innodb  --rand-init=on  --mysql-host=**** --mysql-port=*** --mysql-db=*** --max-time=300 --max-requests=0   --oltp_skip_trx=on --oltp_auto_inc=off --oltp_secondary --oltp_range_size=5 --mysql_table_options='dbpartition by hash(`id`) tbpartition by hash(`id`) tbpartitions 2' --num-threads=200 cleanup

sysbench自定义lua脚本实现实际的业务逻辑压力测试

sysbench自定义lua脚本实现实际的业务逻辑压力测试

使用sysbench进行mysql的oltp测试，一般的测试在sysbench中在tests/db中提供了一个oltp.lua脚本可以进行oltp的压力测试。
但不能完全模拟自己实际业务的压力测试，不同的业务，数据结构，数据量都是不一样的，为了更接近实际业务的读写压力测试，就得自己写lua脚本，然后通过sysbench进行压力测试。
写这个lua脚本很简单，只需要会写lua脚本就可以了。 写这个lua脚本很简单，只需要会写lua脚本就可以了。

1、首先收集实际业务的访问数据库的sql；
2、准备一台恢复好的备份库（从线上导一个）
3、将收集的sql写在lua脚本里（具体如何写，后面举个例子）4、通过sysbench的--test参数和--mysql-db参数进行测试（这里就不需要prepare了，直接run就行）
4、通过sysbench的--test参数和--mysql-db参数进行测试（这里就不需要prepare了，直接run就行）

举个小例子
模拟实际业务环境： 模拟实际业务环境：

CREATE TABLE `t1` (
  `id` int(10) NOT NULL AUTO_INCREMENT,
  `name` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=10101 DEFAULT CHARSET=utf8
) ENGINE=InnoDB AUTO_INCREMENT=10101 DEFAULT CHARSET=utf8

插入模拟的际业务数据：

delimiter $$
create procedure add_data(in maxnum int) 
begin 
    declare i int default 0;
    declare s varchar(500); 
    while(i<maxnum) do 
        select concat("abcdedsfsfsdfsfsf",i) into s; 
        insert into t1(name)values(s);  
        set i=i+1;
    end while;
end $$ 
delimiter ;call add_data(10000);

call add_data(10000);

准备lua脚本：[root@sever3 db]# cat test.lua

function thread_init(thread_id)
   -- set_vars()
   db_connect()
end

function event(thread_id)
   local table_name
   local rs
   table_name = "t1"
        db_query("begin")
  for i=1, 10000 do
      rs = db_query("SELECT name FROM ".. table_name .." WHERE id=" .. i)
  endend
end

set_vars() 如果需要使用更多的参数，需要执行这个，前面需要引用下common.lua

db_connect() 是连接数据库的，这个是sysbench里的函数，不管那么多，直接用就行。

thread_init() 第一个调用的lua函数

event(thread_id) 可以把sql逻辑写到这里， --num-threads多少个，就会同时调用多少个

然后进行压测就ok

[root@sever3 sysbench]# ./sysbench --mysql-socket=/data/mysql_3309/mysql.sock --test=tests/db/test.lua --mysql-user=root --num-threads=12 --report-interval=10 --rand-type=uniform --max-time=30 --max-requests=0 --percentile=99 --mysql-db=test run

别人的demo

pathtest = string.match(test, "(.*/)") or ""

dofile(pathtest .. "common.lua")

function thread_init(thread_id)
   set_vars()

   if (db_driver == "mysql" and mysql_table_engine == "myisam") then
      begin_query = "LOCK TABLES sbtest WRITE"
      commit_query = "UNLOCK TABLES"
   else
      begin_query = "BEGIN"
      commit_query = "COMMIT"
   end
end

function event(thread_id)
   local vid1
   local vid2
   local vid3

   rs = db_query("insert into test6 (k,xv) values " .. string.format("(%d , '%s')",vk,vxv));

end

利用sysbench快速插入海量数据到数据库

1.准备两个表，

CREATE TABLE `employ` (
  `id` bigint(20) NOT NULL COMMENT '员工编号',
  `name` varchar(48) NOT NULL COMMENT '名字',
  `departmentId` bigint(10) NOT NULL COMMENT '部门编号',
  `datasourceId` varchar(64) NOT NULL COMMENT '数据存储位置',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `employExt` (
  `userid` bigint(20) NOT NULL COMMENT '员工编号',
  `username` varchar(48) NOT NULL COMMENT '名字',
  `address` varchar(255) NOT NULL COMMENT '地址',
  `phone` char(11) NOT NULL COMMENT '号码',
  `cardId` char(18) NOT NULL COMMENT '身份证号码',
  PRIMARY KEY (`userid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

第二步编写lua脚本

#!/usr/bin/env sysbench

require("oltp_common")


function thread_init()
   if (db_driver == "mysql" and mysql_table_engine == "myisam") then
      begin_query = "LOCK TABLES sbtest WRITE"
      commit_query = "UNLOCK TABLES"
   else
      begin_query = "BEGIN"
      commit_query = "COMMIT"
   end
   drv = sysbench.sql.driver()
   con = drv:connect()
   stmt = {}
   param = {}

   for t = 1, sysbench.opt.tables do
      stmt[t] = {}
      param[t] = {}
   end

   -- This function is a 'callback' defined by individual benchmark scripts
   prepare_statements()
end

function prepare_statements()
   -- We do not use prepared statements here, but oltp_common.sh expects this
   -- function to be defined
end

function event(thread_id)
   local table_name = "employ"
   local table1_name = "employExt"
   local employ_name = get_c_value()
   local departmentId = sb_rand_uniform(10,10000)
   local datasourceId = "db1"

   if (sysbench.opt.auto_inc) then
      i = 0
   else
         -- Convert a uint32_t value to SQL INT
      i = sysbench.rand.unique() - 2147483648
   end
      con:query(string.format("INSERT INTO %s (id, name, departmentId, datasourceId) VALUES " ..
                                 "(%d, %s, '%d', '%s')",
                              table_name, i, employ_name, departmentId, datasourceId))
end
