今天就跟大家聊聊有關(guān)怎樣進(jìn)行mysql  sysbench1.0.3 安裝以及系統(tǒng)壓力測試，可能很多人都不太了解，為了讓大家更加了解，小編給大家總結(jié)了以下內(nèi)容，希望大家根據(jù)這篇文章可以有所收獲。

成都創(chuàng)新互聯(lián)長期為千余家客戶提供的網(wǎng)站建設(shè)服務(wù)，團(tuán)隊從業(yè)經(jīng)驗10年，關(guān)注不同地域、不同群體，并針對不同對象提供差異化的產(chǎn)品和服務(wù)；打造開放共贏平臺，與合作伙伴共同營造健康的互聯(lián)網(wǎng)生態(tài)環(huán)境。為汾陽企業(yè)提供專業(yè)的網(wǎng)站設(shè)計制作、網(wǎng)站設(shè)計，汾陽網(wǎng)站改版等技術(shù)服務(wù)。擁有10多年豐富建站經(jīng)驗和眾多成功案例,為您定制開發(fā)。

針對系統(tǒng)和數(shù)據(jù)庫壓測是項目上線前必做的一項，這里使用的是最新版本的sysbench做的壓測使用詳解。sysbench可以做系統(tǒng)層面的壓力測試（CPU、內(nèi)存、硬盤IO、互斥鎖、Thead），也可以做數(shù)據(jù)庫（MySQL/Oracle/PG）層面的壓力測試。安裝容易，操作便捷，是壓測使用的重要工具之一。

三、sysbench使用
1、CPU性能測試

cpu性能測試：找范圍內(nèi)大素數(shù){時間越短越好}

cpu性能測試主要是根據(jù)素數(shù)的加法運(yùn)算，這里指定大素數(shù)(質(zhì)數(shù))為80000，--num-threads=`grep "processor" /proc/cpuinfo | wc -l`指定線程數(shù)，默認(rèn)是1

1. [root@db_test ~]# /usr/local/sysbench/bin/sysbench --test=cpu --cpu-max-prime=80000 run

2. WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.

3. sysbench 1.0.3 (using bundled LuaJIT 2.1.0-beta2)

5. Running the test with following options:

6. Number of threads: 1

7. Initializing random number generator from current time

10. Prime numbers limit: 80000

12. Initializing worker threads...

14. Threads started!

17. General statistics:

18. total time: 10.0057s

19. total number of events: 520

21. Latency (ms):

22. min: 18.74

23. avg: 19.24

24. max: 19.39

25. 95th percentile: 19.29

26. sum: 10005.32

28. Threads fairness:

29. events (avg/stddev): 520.0000/0.00

30. execution time (avg/stddev): 10.0053/0.00

實際環(huán)境CPU拷機(jī)壓測腳本如下：

echo -e "進(jìn)行CPU壓力測試: 尋找小于1千萬的大質(zhì)數(shù),并發(fā)線程數(shù)10,大請求數(shù)100 "

/usr/local/bin/sysbench --num-threads=10 --max-requests=100 --test=cpu --debug --cpu-max-prime=10000000 run

2、內(nèi)存性能測試

sysbench 測試memory的時候是順序讀或?qū)憙?nèi)存的。根據(jù)選項的不同，每次操作過程中，每個線程可以獲取global或本地的數(shù)據(jù)塊

內(nèi)存：以不同塊大小傳輸一定數(shù)量的數(shù)據(jù)吞吐量大小{越大越好}

1. [root@db_test fileio]# /usr/local/sysbench/bin/sysbench --test=memory help

2. WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.

3. sysbench 1..3 (using bundled LuaJIT 2.1.-beta2)

5. memory options:

6.   --memory-block-size=SIZE size of memory block for test [1K]  測試時內(nèi)存塊大小

7.   --memory-total-size=SIZE total size of data to transfer [100G] 傳輸數(shù)據(jù)總大小

8.   --memory-scope=STRING memory access scope {global,local} [global]  內(nèi)存訪問范圍

9.   --memory-hugetlb[=on|off] allocate memory from HugeTLB pool [off] 從<span "="" style="color: rgb(0, 0, 0); font-size: 10.5pt;"> HugeTLB pool內(nèi)存分配

10.   --memory-oper=STRING type of memory operations {read, write, none} [write] 內(nèi)存操作類型

11.   --memory-access-mode=STRING memory access mode {seq,rnd} [seq] 存儲器存取方式

示例：測試傳輸數(shù)據(jù)總量為5G，每個塊大小是1K（一般設(shè)置是8K），連續(xù)讀寫的情況下，吞吐量3435.87 MiB/sec
[root@db_test fileio]# /usr/local/sysbench/bin/sysbench --test=memory --memory-block-size=1K --memory-total-size=5G run
