sysbench的安装与使用（with MySQL）

sysbench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。

项目主页： http://sysbench.sourceforge.net/

安装文档http://sysbench.sourceforge.net/docs/#install

但是好像这两天打不开，在这儿提供一个0.4.12版的下载：sysbench-0.4.12.tar.gz

一.安装三步骤：

1.configure

./configure --prefix=/u01/sysbench/ --with-mysql-includes=/usr/include/mysql/ --with-mysql-libs=/usr/lib/mysql/ --with-mysql

其中标红的地方为mysql的2个路径，我在这个地方偷懒用的直接是yum install的方式安装的，所以路径为默认的这个。如果是自定义的，比如/u01/mysql之类的，那么路径就改成相应的就可以了。

2.make

这一步会根据上一步生成的makefile来进行make，但之前的configure里面，生成makefile的时候，是用的32位的包，所以需要ln一下，使用64位的包：

ln -s /usr/lib64/mysql/* /usr/lib/mysql/，再执行autogen.sh，再执行make

3.make install

 

二.使用

 

首先，看看sysbench支持哪些功能参数：

[root@monsrv bin]# sysbench --hlp
Unknown option: --hlp.
Usage:
  sysbench [general-options]... --test=<test-name> [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
  cpu - CPU performance test
  memory - Memory functions speed test
  threads - Threads subsystem performance test
  mutex - Mutex performance test
  oltp - OLTP test

Commands: prepare run cleanup help version

See 'sysbench --test=<name> help' for a list of options for each test.

 

从帮助可以看出，sysbench的测试主要包括以下几个方面：

(1)磁盘io性能

(2)cpu性能

(3)内存分配及传输速度

(4)线程性能

(5)mutex性能

(6)OLTP基准测试

 

2.1 测试fileio命令帮助：

[root@monsrv bin]# sysbench --test=fileio help 
sysbench 0.4.12:  multi-threaded system evaluation benchmark

fileio options:
  --file-num=N                  number of files to create [128]
  --file-block-size=N           block size to use in all IO operations [16384]
  --file-total-size=SIZE        total size of files to create [2G]
  --file-test-mode=STRING       test mode {seqwr, seqrewr, seqrd, rndrd, rndwr, rndrw}
  --file-io-mode=STRING         file operations mode {sync,async,fastmmap,slowmmap} [sync]
  --file-async-backlog=N        number of asynchronous operatons to queue per thread [128]
  --file-extra-flags=STRING     additional flags to use on opening files {sync,dsync,direct} []
  --file-fsync-freq=N           do fsync() after this number of requests (0 - don't use fsync()) [100]
  --file-fsync-all=[on|off]     do fsync() after each write operation [off]
  --file-fsync-end=[on|off]     do fsync() at the end of test [on]
  --file-fsync-mode=STRING      which method to use for synchronization {fsync, fdatasync} [fsync]
  --file-merged-requests=N      merge at most this number of IO requests if possible (0 - don't merge) [0]
  --file-rw-ratio=N             reads/writes ratio for combined test [1.5]

 

参数详解：

--file-num=N          代表生成测试文件的数量，默认为128。

--file-block-size=N      测试时所使用文件块的大小，如果想磁盘针对innodb存储引擎进行测试，可以将其设置为16384，即innodb存储引擎页的大小。默认为16384。

--file-total-size=SIZE     创建测试文件的总大小，默认为2G大小。

--file-test-mode=STRING 文件测试模式，包含：seqwr(顺序写), seqrewr(顺序读写), seqrd(顺序读), rndrd(随机读), rndwr(随机写), rndrw(随机读写)。

--file-io-mode=STRING   文件操作的模式，sync（同步）,async（异步）,fastmmap（快速mmap）,slowmmap（慢速mmap），默认为sync同步模式。

--file-async-backlog=N   对应每个线程队列的异步操作数，默认为128。

--file-extra-flags=STRING 打开文件时的选项，这是与API相关的参数。

--file-fsync-freq=N      执行fsync()函数的频率。fsync主要是同步磁盘文件，因为可能有系统和磁盘缓冲的关系。 0代表不使用fsync函数。默认值为100。

--file-fsync-all=[on|off]  每执行完一次写操作，就执行一次fsync。默认为off。

--file-fsync-end=[on|off] 在测试结束时执行fsync函数。默认为on。

--file-fsync-mode=STRING文件同步函数的选择，同样是和API相关的参数，由于多个操作系统对于fdatasync支持不同，因此不建议使用fdatasync。默认为fsync。

--file-merged-requests=N 大多情况下，合并可能的IO的请求数，默认为0。

--file-rw-ratio=N         测试时的读写比例，默认时为1.5，即可3：2。

 

示例：

生成16个总共2G的文件，进行读写io测试

测试结果主要看标黄色的那一段。为了稳定，测了2次，看起来差不多。
