这篇文章给大家分享的是有关 MySQL 如何使用 sysbench 做 OLTP 基准测试的内容。丸趣 TV 小编觉得挺实用的,因此分享给大家做个参考,一起跟随丸趣 TV 小编过来看看吧。

一、安装
① 下载源码包:https://dev.mysql.com/downloads/benchmarks.html
② 安装依赖 yum -y install automake autoconf libtool
③tar xzvf sysbench-0.4.12.10.tar.gz; cd sysbench-0.4.12.10/
④./autogen.sh; ./configure
⑤ make make install
然后我们可以在 sysbench 目录看到可以执行文件 sysbench 了

二、命令
首先看下命令基本用法  

root@10.30.5.2:sysbench# ./sysbench –help

Usage:

sysbench [general-options]… –test= [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]

–seed-rng=N                seed for random number generator, ignored when 0 [0]

–tx-rate=N                 target transaction rate (tps) [0]

–tx-jitter=N               target transaction variation, in microseconds [0]

–report-interval=N         periodically report intermediate statistics with a specified interval in seconds. 0 disables intermediate reports [0]

–report-checkpoints=[LIST,…]dump full statistics and reset all counters at specified points in time. The argument is a list of comma-separated values representing the amount of time in seconds elapsed from start of test when report checkpoint(s) must be performed. Report checkpoints are off by default. []

–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

Log options:

–verbosity=N      verbosity level {5 – debug, 0 – only critical messages} [4]

–percentile=N      percentile rank of query response times to count [95]

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= help for a list of options for each test.

以上可以看到 sysbench 可以测试的有 CPU、磁盘 IO、内存、线程、MUTEX 以及 OLTP,
常用参数:
–num-threads=N     并发线程数
–max-requests=N     限制压测请求总数
–max-time=N    限制压测时间

这里看下 OLTP 测试方法

总结:
1 PREPARE 阶段
    在 PREPARE 阶段我们就需要想好,此时 mysql 的配置,如 innodb_flush_log_at_trx_commit、sync_binlog 以及 BP 的大小等。
    然后结合 BP 的大小我们需要创建表的记录数,表的个数,并发线程等,综合考虑
   ① 若数据量 BP 所有数据都会缓存到内存,此时增加 并发线程数 来测整个此时的 CPU 核数是否能抗住测试压力
   ② 若数据量 BP 则主要测试整个系统的稳定性,我们可以结合监控看缓存命中率(orzdba),以及对应的 磁盘 IO(iostat / orzdba) 等,来获取整个数据库系统的薄弱点

2 RUN 阶段
    在 RUN 阶段的同时,我们可以通过 orzdba/iostat 等工具查看当前的数据库状态
    ① 上面的测试结果我们可以看到,   
     transactions: 200016 (2000.64 per sec.) TPS 大概为 2000
     read/write requests: 3800304 (38012.16 per sec.) QPS 达到 38000
 approx. 95 percentile: 52.10ms  95% 的请求相应时间在 52.10ms 左右
    可以说性能是相当不错了(这里我测试的是腾讯云 CDB , 配置为 1000MB 的 BP)
    ② 通过 orzdba 结合 running 过程查看数据库状态

    可以发现 在 32 个 thread 并发进行 complex 操作的时候,每秒的 insert 量 update 量 delete 量 select 量可以看得非常清楚,还有 innodb_log 的 fsync 量,以及数据库的 response time。
