sysbench 安装、使用和测试
摘要:
sysbench是一个开源的、模块化的、跨平台的多线程性能测试工具,可以用来进行CPU、内存、磁盘I/O、线程、数据库的性能测试。目前支持的数据库有MySQL、Oracle和PostgreSQL。当前功能允许测试的系统参数有:
file I/O performance (文件I / O性能)
scheduler performance (调度性能)
memory allocation and transfer speed (内存分配和传输速度)
POSIX threads implementation performance (POSIX线程执行绩效)
database server performance (OLTP benchmark) (数据库服务器性能)
安装:
1):Ubuntu系统可以直接apt,如:
apt-get install sysbench
2):其他系统的则可以编译安装[在/home/zhoujy/目录下]:(安装前先装automake,libtool)
wget http://nchc.dl.sourceforge.net/project/sysbench/sysbench/0.4.12/sysbench-0.4.12.tar.gz tar zxvf sysbench-0.4.12.tar.gz
进入解压目录,并且创建安装目录: root@m2:/home/zhoujy# cd sysbench-0.4.12/ root@m2:/home/zhoujy/sysbench-0.4.12# mkdir /usr/sysbench/
准备编译 root@m2:/home/zhoujy/sysbench-0.4.12# apt-get install automake
root@m2:/home/zhoujy/sysbench-0.4.12#apt-get install libtool
root@m2:/home/zhoujy/sysbench-0.4.12# ./autogen.sh
要是出现:perl: warning: Falling back to the standard locale ("C")。则需要设置locale:
echo "export LC_ALL=C" >> /root/.bashrc source /root/.bashrc
要是没有安装开发包,即/usr/include/ 目录下面没有mysql文件夹。则需要执行安装(版本为12.04):
sudo apt-get install libmysqlclient-dev sudo apt-get install libmysqld-dev sudo apt-get install libmysqld-pic
执行configure操作:
./configure --prefix=/usr/sysbench/ --with-mysql-includes=/usr/include/mysql/ --with-mysql-libs=/usr/lib/mysql/ --with-mysql
说明:
--prefix=/usr/sysbench/ :指定sysbench的安装目录。
--with-mysql-includes=/usr/include/mysql/ :指定安装mysql时候的includes目录。
--with-mysql-libs=/usr/lib/mysql/ :指定装mysql时候的lib目录。
--with-mysql :sysbench默认支持mysql,如果需要测试oracle或者pgsql则需要制定–with-oracle或者–with-pgsql。
在这里需要先执行:
cp /usr/bin/libtool /home/zhoujy/sysbench-0.4.12/libtool
再make和make install。否者会出现 libtool 报出的 Xsysbench: command not found 错误,则表示编译文件包的libtool版本太低,需要替换。

###################################更新2016-07-27
今天使用sysbench的时候,发现0.5版本已经没有 --test=oltp的参数,现在就更新说明下0.5版本的sysbench 如何使用oltp的测试。
① 安装:通过apt-get install sysbench
root@t22:~# sysbench --test=oltp help sysbench 0.5: multi-threaded system evaluation benchmark PANIC: unprotected error in call to Lua API (cannot open oltp: No such file or directory)
sysbench 0.5相比0.4版本有一些变化,包括oltp测试结合了lua脚本。通过dpkg -L sysbench查看相关文件:
root@t22:~# dpkg -L sysbench /. /usr /usr/bin /usr/bin/sysbench /usr/share /usr/share/doc /usr/share/doc/sysbench /usr/share/doc/sysbench/copyright /usr/share/doc/sysbench/TODO /usr/share/doc/sysbench/changelog.Debian.gz /usr/share/doc/sysbench/README /usr/share/doc/sysbench/manual.html /usr/share/doc/sysbench/tests /usr/share/doc/sysbench/tests/db /usr/share/doc/sysbench/tests/db/oltp_simple.lua /usr/share/doc/sysbench/tests/db/insert.lua /usr/share/doc/sysbench/tests/db/select_random_ranges.lua /usr/share/doc/sysbench/tests/db/oltp.lua /usr/share/doc/sysbench/tests/db/common.lua /usr/share/doc/sysbench/tests/db/select_random_points.lua /usr/share/doc/sysbench/tests/db/delete.lua /usr/share/doc/sysbench/tests/db/update_non_index.lua /usr/share/doc/sysbench/tests/db/update_index.lua /usr/share/doc/sysbench/tests/db/parallel_prepare.lua /usr/share/doc/sysbench/tests/db/select.lua
②:参数介绍
--test=tests/db/oltp.lua 表示调用 tests/db/oltp.lua 脚本进行 oltp 模式测试
--mysql-table-engine=innodb 表示选择测试表的存储引擎 --oltp_tables_count=10 表示会生成 10 个测试表 --oltp-table-size=100000 表示每个测试表填充数据量为 100000 --rand-init=on 表示每个测试表都是用随机数据来填充的 如果在本机,也可以使用 –mysql-socket 指定 socket 文件来连接。加载测试数据时长视数据量而定,若过程比较久需要稍加耐心等待。
--num-threads=8 表示发起 8个并发连接 --oltp-read-only=off 表示不要进行只读测试,也就是会采用读写混合模式测试 --report-interval=10 表示每10秒输出一次测试进度报告 --rand-type=uniform 表示随机类型为固定模式,其他几个可选随机模式:uniform(固定),gaussian(高斯),special(特定的),pareto(帕累托) --max-time=120 表示最大执行时长为 120秒 --max-requests=0 表示总请求数为 0,因为上面已经定义了总执行时长,所以总请求数可以设定为 0;也可以只设定总请求数,不设定最大执行时长 --percentile=99 表示设定采样比例,默认是 95%,即丢弃1%的长请求,在剩余的99%里取最大值
具体的说明可以看sysbench安装、使用、结果解读和使用sysbench对mysql压力测试。
③:使用说明
初始化数据:prepare。在本地数据库的dba_test库中,初始化三张表(sbtest1、sbtest2、sbtest3),存储引擎是innodb,每张表50万数据。
sysbench --test=/usr/share/doc/sysbench/tests/db/oltp.lua --mysql-table-engine=innodb --mysql-host=127.0.0.1 --mysql-db=dba_test --oltp-table-size=500000 --oltp_tables_count=3 --rand-init=on --mysql-user=zjy --mysql-password=zjy prepare
因为是本机测试,所以也可以用也可以使用--mysql-socket指定socket文件来连接。
测试:run。模拟对3个表并发OLTP测试,每个表50万行记录,持续压测时间为5分钟。
sysbench --test=/usr/share/doc/sysbench/tests/db/oltp.lua --mysql-table-engine=innodb --mysql-host=127.0.0.1 --mysql-db=dba_test --num-threads=8 --oltp-table-size=500000 --oltp_tables_count=3 --oltp-read-only=off --report-interval=10 --rand-type=uniform --max-time=600 --max-requests=0 --percentile=99 --mysql-user=zjy --mysql-password=zjy run
