在使用sysbench 之前 先要避免一個坑。。（搞了一上午才跳過去）：

sysbench的版本有好多，每個版本對應的命令是不同的，語法也是有相當一部分的差異，所以一定要按照你安裝的版本，去sysbench --help 仔細看相關的命令，不然就會一直報各種語法錯誤。。

例如：在sysbench 0.4版本中 --help可以看到Compiled-in tests 下 有oltp基準測試的選項，而且可以用sysbench --test=oltp help 檢視具體引數配置。而在1.0及以上的版本中是沒有這個選項的。。

一.安裝三步驟：

1.configure

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

其中標紅的地方為mysql的2個路徑，我在這個地方偷懶用的直接是yum install的方式安裝的，所以路徑為預設的這個。如果是自定義的，比如/u01/mysql之類的，那麼路徑就改成相應的就可以了。

2.make

這一步會根據上一步生成的makefile來進行make，但之前的configure裡面，生成makefile的時候，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/，再執行autogen.sh，再執行make

3.make install

二.使用

首先，看看sysbench支援哪些功能引數：

[[email protected] 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.

從幫助可以看出，sysbench的測試主要包括以下幾個方面：

(1)磁碟io效能

(2)cpu效能

(3)記憶體分配及傳輸速度

(4)執行緒效能

(5)mutex效能

(6)OLTP基準測試

2.1 測試fileio命令幫助：

[[email protected] 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]

引數詳解：

--file-num=N          代表生成測試檔案的數量，預設為128。

--file-block-size=N      測試時所使用檔案塊的大小，如果想磁碟針對innodb儲存引擎進行測試，可以將其設定為16384，即innodb儲存引擎頁的大小。預設為16384。

--file-total-size=SIZE     建立測試檔案的總大小，預設為2G大小。

--file-test-mode=STRING 檔案測試模式，包含：seqwr(順序寫), seqrewr(順序讀寫), seqrd(順序讀), rndrd(隨機讀), rndwr(隨機寫), rndrw(隨機讀寫)。

--file-io-mode=STRING   檔案操作的模式，sync（同步）,async（非同步）,fastmmap（快速mmap）,slowmmap（慢速mmap），預設為sync同步模式。

--file-async-backlog=N   對應每個執行緒佇列的非同步運算元，預設為128。

--file-extra-flags=STRING 開啟檔案時的選項，這是與API相關的引數。

--file-fsync-freq=N      執行fsync()函式的頻率。fsync主要是同步磁碟檔案，因為可能有系統和磁碟緩衝的關係。 0代表不使用fsync函式。預設值為100。

--file-fsync-all=[on|off]  每執行完一次寫操作，就執行一次fsync。預設為off。

--file-fsync-end=[on|off] 在測試結束時執行fsync函式。預設為on。

--file-fsync-mode=STRING檔案同步函式的選擇，同樣是和API相關的引數，由於多個作業系統對於fdatasync支援不同，因此不建議使用fdatasync。預設為fsync。

--file-merged-requests=N 大多情況下，合併可能的IO的請求數，預設為0。

--file-rw-ratio=N         測試時的讀寫比例，預設時為1.5，即可3：2。

示例：

生成16個總共2G的檔案，進行讀寫io測試
