性能测试工具sysbench简介
By admin
- 5 minutes read - 965 wordssysbench是一款开源的多线程性能测试工具，可以执行CPU/内存/线程/IO/数据库等方面的性能测试。数据库目前支持MySQL/Oracle/PostgreSQL。本文只是简单演示一下几种测试的用法，后续准备利用sysbench来对MySQL进行一系列的测试。具体的一些参数设置，需要根据不同的测试要求来进行调整。
下载
** 编译安装** 默认支持MySQL，如果需要测试Oracle/PostgreSQL，则在configure时需要加上–with-oracle或者–with-pgsql参数
./configure --prefix=/u01/sysbench \
--with-mysql-includes=/opt/mysql/include/mysql \
--with-mysql-libs=/opt/mysql/lib/mysql
make && make install
参数
NinGoo:/u01/sysbench/bin>$sysbench
Missing required command argument.
Usage:
sysbench [general-options]... --test= [test-options]... command
General options:
--num-threads=N number of threads to use [1]
--max-requests=N limit for total number of requests [10000]
--max-time=N limit for total execution time in seconds [0]
--forced-shutdown=STRING amount of time to wait after --max-time before forcing shutdown [off]
--thread-stack-size=SIZE size of stack per thread [32K]
--init-rng=[on|off] initialize random number generator [off]
--test=STRING test to run
--debug=[on|off] print more debugging info [off]
--validate=[on|off] perform validation checks where possible [off]
--help=[on|off] print help and exit
--version=[on|off] print version and exit
Compiled-in tests:
fileio - File I/O test

Commands: prepare run cleanup help version
See 'sysbench --test= help' for a list of options for each test.
