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
准备工作：
[root@monsrv bin]# sysbench --test=fileio --file-num=16 --file-total-size=2G prepare sysbench 0.4.12: multi-threaded system evaluation benchmark 16 files, 131072Kb each, 2048Mb total Creating files for the test...

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。
测试完成后，需要把测试文件给删掉。

示例：
首先准备sbest测试表，因为脚本默认不会建库，那么需要先在MySQL中吧库建好，当然也可以用参数--mysql-db指定数据库。
[root@monsrv ~]# sysbench --test=oltp --num-threads=1 --max-requests=80000 --oltp-test-mode=complex --db-driver=mysql --mysql-db=sbtest --mysql-host=192.168.0.155 --mysql-port=1234 --mysql-user=root --mysql-password=aostarit --oltp-nontrx-mode=select --db-ps-mode=disable prepare sysbench 0.4.12: multi-threaded system evaluation benchmark Creating table 'sbtest'... Creating 10000 records in table 'sbtest'...
接着就是测试了。我在这儿设置了80000个请求，也就是说这个测试需要做完80000个request才会停止，可以适当的调整。
[root@monsrv ~]# sysbench --test=oltp --num-threads=1 --max-requests=80000 --oltp-test-mode=complex --db-driver=mysql --mysql-db=sbtest --mysql-host=192.168.0.155 --mysql-port=1234 --mysql-user=root --mysql-password=aostarit --oltp-nontrx-mode=select --db-ps-mode=disable run sysbench 0.4.12: multi-threaded system evaluation benchmark Running the test with following options: Number of threads: 1 Doing OLTP test.

最后就是清除
