mysql 压力测试之sysbench
1.sysbench 的安装
下载sysbench 源码包 http://down1.chinaunix.net/distfiles/sysbench-0.4.10.tar.gz
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
No DB drivers specified, using mysql
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
No DB drivers specified, using mysql
WARNING: Preparing of "BEGIN" is unsupported, using emulation
(last message repeated 7 times)
Running the test with following options:

Using "BEGIN" for starting transactions
Using auto_inc on the id column
Maximum number of requests for OLTP test is limited to 4000000
Threads started!
Done.
OLTP test statistics:

transactions: 4000000 (125.37 per sec.)
deadlocks: 0 (0.00 per sec.)
read/write requests: 76000000 (2381.99 per sec.)
other operations: 8000000 (250.74 per sec.)
Test execution summary:
total time: 31906.1255s
total number of events: 4000000
total time taken by event execution: 255224.4528
per-request statistics:
min: 2.69ms
avg: 63.81ms
max: 5557.09ms
approx. 95 percentile: 178.90ms

QPS(transactions: 4000000 (125.37 per sec.)) ，
tps( transactions: 4000000 (125.37 per sec.))
百分之95的请求耗时在178.90ms ： approx. 95 percentile: 178.90ms
