怎样进行mysql sysbench1.0.3 安装以及系统压力测试

今天就跟大家聊聊有关怎样进行mysql  sysbench1.0.3 安装以及系统压力测试，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

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. [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

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}

点击(此处)折叠或打开

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]  测试时内存块大小

7.   –memory-total-size=SIZE total size of data to transfer [100G] 传输数据总大小

8.   –memory-scope=STRING memory access scope {global,local} [global]  内存访问范围

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

10.   –memory-oper=STRING type of memory operations {read, write, none} [write] 内存操作类型

11.   –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
[root@db_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.

实际内存压力测试脚本：

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, 读 "

/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 "

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