mysql 压力测试之sysbench

1.sysbench 的安装

下载下来之后会有一个sysbench-0.4.10.tar.gz  压缩包.

解压后生成目录 sysbench-0.4.10

进入sysbench-0.4.10 这个目录

[root@linuxvm01 home]# cd  /home/sysbench-0.4.10

编译安装sysbench

[root@linuxvm01 sysbench-0.4.10]# ./configure --with-mysql-includes=/usr/include/mysql --with-mysql-libs=/usr/lib  && make && make install

checking build system type... x86_64-unknown-linux-gnu

checking host system type... x86_64-unknown-linux-gnu

checking target system type... x86_64-unknown-linux-gnu

checking for a BSD-compatible install... /usr/bin/install -c

checking whether build environment is sane... yes

checking for a thread-safe mkdir -p... /bin/mkdir -p

checking for gawk... gawk

TIP:

with-mysql-includes 指定上面确认的mysql-devel的路径，

with-mysql-libs 是安装mysql的路径，

#  当时这两个参数没弄明白编译安装的时候一直报错,

安装过程中出现的错误处理

(1).drv_mysql.c:32:19: error: mysql.h: No such file or directory

参数 with-mysql-includes ,with-mysql-libs 不准确

(2)./usr/bin/ld: cannot find -lmysqlclient_r

collect2: ld returned 1 exit status

make[2]: *** [sysbench] Error 1

make[2]: Leaving directory `/home/sysbench-0.4.10/sysbench'

make[1]: *** [all-recursive] Error 1

make[1]: Leaving directory `/home/sysbench-0.4.10/sysbench'

make: *** [all-recursive] Error 1

安装下：rpm -ivh  MySQL-shared-5.6.22-1.el6.x86_64.rpm

2.sysbench 的使用

sysbench 可以测试的项目有

cpu的性能测试

内存性能测试

磁盘io吸能测试

oltp系统测试

最重要的还是 磁盘io吸能测试 和oltp 测试。

这里重点讲解下磁盘io吸能测试 和oltp 测试。

=====磁盘io性能测试 ==============

IO测试分为三个阶段, 文件生成,执行测试,清理测试文件

首先生成需要测试的文件

sysbench --test=fileio --num-threads=2 --file-num=16 --file-total-size=30G --file-test-mode=rndrw --file-rw-ratio=2 prepare

[root@linuxvm01 ~]# sysbench --test=fileio --num-threads=2 --file-num=16 --file-total-size=30G --file-test-mode=rndrw --file-rw-ratio=2 prepare

sysbench 0.4.10:  multi-threaded system evaluation benchmark

16 files, 1966080Kb each, 30720Mb total

Creating files for the test...

然后执行测试

sysbench --test=fileio --num-threads=2 --file-num=16 --file-total-size=30G --file-test-mode=rndrw --file-rw-ratio=2 run

[root@linuxvm01 ~]# sysbench --test=fileio --num-threads=2 --file-num=16 --file-total-size=30G --file-test-mode=rndrw --file-rw-ratio=2 run

sysbench 0.4.10:  multi-threaded system evaluation benchmark

Running the test with following options:

Number of threads: 2

Extra file open flags: 0

16 files, 1.875Gb each

30Gb total file size

Block size 16Kb

Number of random requests for random IO: 10000

Read/Write ratio for combined random IO test: 2.00

Periodic FSYNC enabled, calling fsync() each 100 requests.

Calling fsync() at the end of test, Enabled.

Using synchronous I/O mode

Doing random r/w test

Threads started!

Done.

Operations performed:  6667 Read, 3333 Write, 1600 Other = 11600 Total

Read 104.17Mb  Written 52.078Mb  Total transferred 156.25Mb  (2.0936Mb/sec)

133.99 Requests/sec executed

Test execution summary:

total time:                          74.6328s

total number of events:              10000

total time taken by event execution: 142.3936

per-request statistics:

min:                                  0.01ms

avg:                                 14.24ms

max:                                305.56ms

approx.  95 percentile:              37.48ms

Threads fairness:

events (avg/stddev):           5000.0000/12.00

execution time (avg/stddev):   71.1968/0.09

这个里面最重要的需要关注的吞吐量(2.0936Mb/sec) ，

每秒请求数( 133.99 Requests/sec executed)

还有95%的请求耗时( approx.  95 percentile:              37.48ms)

最后清理测试文件

sysbench --test=fileio --num-threads=2 --file-num=16 --file-total-size=30G --file-test-mode=rndrw --file-rw-ratio=2 cleanup

=====OLTP 系统性能测试 ==============

otlp性能测试分为两阶段.

1.准备阶段

2.执行阶段

--准备阶段

[root@linuxvm01 ~]# sysbench --test=oltp --mysql-table-engine=innodb --oltp-table-size=4000000 --mysql-socket=/var/lib/mysql/mysql.sock --mysql-db=test  --mysql-user=root  --mysql-password=anyu@2014 prepare

sysbench 0.4.10:  multi-threaded system evaluation benchmark

Creating table 'sbtest'...

Creating 4000000 records in table 'sbtest'...

-- 执行阶段

[root@linuxvm01 ~]# sysbench --num-threads=8 --max-requests=4000000 --test=oltp --mysql-table-engine=innodb --oltp-table-size=4000000 --mysql-socket=/var/lib/mysql/mysql.sock --mysql-db=test --mysql-user=root  --mysql-password=anyu@2014 run

sysbench 0.4.10:  multi-threaded system evaluation benchmark
