篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了mysql之 sysbench1.0.3 安装与系统压力测试相关的知识,希望对你有一定的参考价值。

针对系统和数据库压测是项目上线前必做的一项,这里使用的是最新版本的sysbench做的压测使用详解。sysbench可以做系统层面的压力测试(CPU、内存、硬盘IO、互斥锁、Thead),也可以做数据库(mysql/Oracle/PG)层面的压力测试。安装容易,操作便捷,是压测使用的重要工具之一。

三、sysbench使用
1、CPU性能测试

cpu性能测试:找范围内最大素数{时间越短越好}

cpu性能测试主要是根据素数的加法运算,这里指定最大素数(质数)为80000,--num-threads=`grep "processor" /proc/cpuinfo | wc -l`指定线程数,默认是1

/usr/local/sysbench/bin/sysbench --test=cpu --cpu-max-prime=80000 run

点击(此处)折叠或打开

  1. [[email protected]_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)
  4. Running the test with following options:
  5. Number of threads: 1
  6. Initializing random number generator from current time
  7. Prime numbers limit: 80000
  8. Initializing worker threads...
  9. Threads started!
  10. General statistics:
  11. total time: 10.0057s
  12. total number of events: 520
  13. Latency (ms):
  14. min: 18.74
  15. avg: 19.24
  16. max: 19.39
  17. 95th percentile: 19.29
  18. sum: 10005.32
  19. Threads fairness:
  20. events (avg/stddev): 520.0000/0.00
  21. execution time (avg/stddev): 10.0053/0.00

实际环境CPU拷机压测脚本如下:

echo -e "进行CPU压力测试: 寻找小于1千万的最大质数,并发线程数10,最大请求数100 "

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


2、内存性能测试

sysbench 测试memory的时候是顺序读或写内存的。根据选项的不同,每次操作过程中,每个线程可以获取global或本地的数据块

内存:以不同块大小传输一定数量的数据吞吐量大小{越大越好}

  1. [[email protected]_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 1.0.3 (using bundled LuaJIT 2.1.0-beta2)
  4. memory options:
  5.   --memory-block-size=SIZE size of memory block for test [1K]  测试时内存块大小
  6.   --memory-total-size=SIZE total size of data to transfer [100G] 传输数据总大小
  7.   --memory-scope=STRING memory access scope {global,local} [global]  内存访问范围
  8.   --memory-hugetlb[=on|off] allocate memory from HugeTLB pool [off] 从<span "=""> HugeTLB pool内存分配

  •   --memory-access-mode=STRING memory access mode {seq,rnd} [seq] 存储器存取方式

示例:测试传输数据总量为5G,每个块大小是1K(一般设置是8K),连续读写的情况下,吞吐量3435.87 MiB/sec
[[email protected]_test fileio]# /usr/local/sysbench/bin/sysbench --test=memory --memory-block-size=1K --memory-total-size=5G run
WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.

/usr/local/bin/sysbench --num-threads=10 --max-requests=100 --test=memory --memory-block-size=8K --memory-total-size=${MEM}G --memory-oper=read run

echo -e "进行内存压力测试: 测试范围32G,并发线程数10,最大请求数100, 写 "
