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
[root@db_test ~]# /usr/local/sysbench/bin/sysbench --test=cpu --cpu-max-prime=80000 run
WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.
sysbench 1.0.3 (using bundled LuaJIT 2.1.0-beta2)
Running the test with following options:
Number of threads: 1
Initializing random number generator from current time
Prime numbers limit: 80000
Initializing worker threads...
Threads started!
General statistics:
total time: 10.0057s
total number of events: 520
Latency (ms):
min: 18.74
avg: 19.24
max: 19.39
95th percentile: 19.29
sum: 10005.32
Threads fairness:
events (avg/stddev): 520.0000/0.00
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}

[root@db_test fileio]# /usr/local/sysbench/bin/sysbench --test=memory help
WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.
sysbench 1..3 (using bundled LuaJIT 2.1.-beta2)
memory options:
--memory-block-size=SIZE size of memory block for test [1K] 测试时内存块大小
--memory-total-size=SIZE total size of data to transfer [100G] 传输数据总大小
--memory-scope=STRING memory access scope {global,local} [global] 内存访问范围

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

/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
3、磁盘IO性能测试
