1 Linux常见基准测试工具
FIO
Sysbench
Phoronix Test Suite (moved to it's own page)
IOzone
Ioping
UnixBench
Google's Perfkit Benchmarker
2 FIO
fio算是比较老的io测试工具了，作者是Jens Axboe。
主页https://www.thomas-krenn.com/en/wiki/Fio
fio的安装
我的测试环境有centos7 redhat5因此要下载两个版本的fio包
redhat5版本的需要去归档站点去下载
http://archives.fedoraproject.org/pub/archive/epel/
下载后的安装 rpm -ivh fio-1.57-1.el5.x86_64.rpm
centos7则可以去很多镜像站点下载，站点列表可以查询
https://admin.fedoraproject.org/mirrormanager/mirrors/EPEL
如果配置了epel的yum源，直接yum install -y fio
fio测试选项和例子
示例 使用fio测试磁盘的随机写
fio --name=randwrite --ioengine=libaio --iodepth=1 --rw=randwrite --bs=4k \
--direct=0 --size=512M --numjobs=8 --runtime=240 --group_reporting
--rw=randwrite指定随机写
--direct=0指定使用buffered IO还是direct IO。如果使用buffer，注意总大小不要超过物理内存
--numjobs=8启动8个进程
--size=512M每个进程写512M
--group_reporting 将多个进程的统计结果进行聚合，更易阅读
--runtime=240持续运行时间4分钟
--bs=4k --blocksize=4k (default)
--ioengine=libaio可用的io引擎可以使用 fio --enghelp查看(fio-2.2.8)
--iodepth=1缺省 测试ssd磁盘时，可以扩大到32，通常4就够了
The iodepth option defines the amount of IO units that will continue to hammer a file with requests during the test.
避免使用buffer的方法是指定--direct=1或者使用比物理内存大一倍的写文件
fio结果的重点关注项目：
iops=1416 iops = 1416
95.00th=[ 2] 95%的IO在2毫秒完成
util=99.62% 设备繁忙程度
示例 使用fio测试磁盘的随机读
fio --name=randread --ioengine=libaio --iodepth=16 --rw=randread --bs=4k \
--direct=0 --size=512M --numjobs=8 --runtime=240 --group_reporting
fio帮助
man fio
fio -h
fio -v
fio命令行中写上选项，也可以将命令行选项写入一个参数文件job file中
fio安装后，自带了一些样例
# rpm -ql -p fio-1.57-1.el5.x86_64.rpm
/usr/bin/fio
/usr/bin/fio_generate_plots
/usr/share/doc/fio-1.57
/usr/share/doc/fio-1.57/COPYING
/usr/share/doc/fio-1.57/HOWTO
/usr/share/doc/fio-1.57/README
/usr/share/doc/fio-1.57/REPORTING-BUGS
/usr/share/doc/fio-1.57/examples
/usr/share/doc/fio-1.57/examples/1mbs_clients
/usr/share/doc/fio-1.57/examples/aio-read
......
aio-read参数文件，修改一下可以马上使用
# fio aio-read.bak
file1: (g=0): rw=randread, bs=128K-128K/128K-128K, ioengine=libaio, iodepth=4
file2: (g=0): rw=randread, bs=128K-128K/128K-128K, ioengine=libaio, iodepth=32
file3: (g=0): rw=randread, bs=128K-128K/128K-128K, ioengine=libaio, iodepth=8
file4: (g=0): rw=randread, bs=128K-128K/128K-128K, ioengine=libaio, iodepth=16
fio 1.57
......
fio输出结果的一些注释
io Number of megabytes of I/O performed.
bw Average data rate (bandwidth).
runt Threads run time.
slat Submission latency minimum, maximum, average and standard deviation. This
is the time it took to submit the I/O.
clat Completion latency minimum, maximum, average and standard deviation. This
is the time between submission and completion.
bw Bandwidth minimum, maximum, percentage of aggregate bandwidth received, average and standard deviation.
The group statistics show:
io Number of megabytes I/O performed.
aggrb Aggregate bandwidth of threads in the group.
minb Minimum average bandwidth a thread saw.
maxb Maximum average bandwidth a thread saw.
mint Shortest runtime of threads in the group.
maxt Longest runtime of threads in the group.
Finally, disk statistics are printed with reads first:
ios Number of I/Os performed by all groups.
merge Number of merges in the I/O scheduler.
ticks Number of ticks we kept the disk busy.
io_queue
Total time spent in the disk queue.
util Disk utilization.
示例 随机读直接IO
fio --name=randread --ioengine=libaio --iodepth=16 --rw=randread --bs=4k --direct=1 --size=1G --numjobs=8 --runtime=240 --group_reporting

3 sysbench
sysbench可以测试cpu \ oltp MySQL\ fileio网上用来测试mysql的文章比较多。
sysbench的安装
在centos中，可以从epel直接安装。安装时需要mysql / postgresql
源文中的安装方法
wget ftp://ftp.gnome.org/mirror/fedora/epel/6/x86_64/sysbench-0.4.12-5.el6.x86_64.rpm
wget http://downloads.mysql.com/archives/mysql-5.1/MySQL-shared-compat-5.1.49-1.rhel5.x86_64.rpm
rpm -iv MySQL-shared-compat-5.1.49-1.rhel5.x86_64.rpm
yum install postgresql-libs.x86_64
rpm -iv sysbench-0.4.12-5.el6.x86_64.rpm
实际安装方法
rpm -ivh http://archives.fedoraproject.org/pub/archive/epel/epel-release-latest-5.noarch.rpm
or
rpm -ivh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum install sysbench
sysbench的I/O测试
先掌握sysbench的语法
# sysbench
Missing required command argument.
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]
--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
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
来一些命令
# run a random write test with "--file-extra-flags=direct"随机写
sysbench --test=fileio --file-total-size=4G --file-num=2 --file-test-mode=rndwr --max-time=240 --max-requests=0 --file-block-size=8K --num-threads=4 --file-extra-flags=direct
prepare
run
cleanup
sysbench --test=fileio --file-total-size=1G --file-num=10 --file-test-mode=rndwr --max-time=240 --max-requests=0 --file-block-size=8K --file-extra-flags=direct
或者
随机写
sysbench --test=fileio --file-total-size=2G --file-num=64 prepare
sysbench --test=fileio --file-total-size=2G --file-test-mode=rndwr --max-time=240 --max-requests=0 --file-block-size=4K --file-num=64 --num-threads=1 run

sleep 10; done
随机读
sysbench --test=fileio --file-total-size=2G --file-test-mode=rndrd --max-time=240 --max-requests=0 --file-block-size=4K --file-num=64 --num-threads=1 run

另外一个虚拟机(笔记本上的VirtualBox)的测试结果
[root@node1 test]# sysbench --test=fileio --file-total-size=4G --file-num=2 --file-test-mode=rndwr --max-time=240 --max-requests=0 --file-block-size=8K --num-threads=4 run

如果测试硬件性能，要在物理服务器上进行对比。
为了避免从内存读取数据，测试文件要大于内存的两倍。
sysbench 的mysql测试
##Create Database
mysql‐u root‐ppassword‐e "CREATE DATABASE sysbench;"
##Create User
mysql‐u root‐ppassword‐e "CREATE USER 'sysbench'@'localhost' IDENTIFIED BY 'password';"
##Grant Access
mysql‐u root‐ppassword‐e "GRANT ALL PRIVILEGES ON *.* TO 'sysbench'@'localhost' IDENTIFIED BY 'password';"
或者
mysql> create database sysbench;
mysql> create user 'sysbench'@'%' identified by 'sysbench' ;
mysql> select host,user from mysql.user;
+-----------+-----------+
| host | user |
+-----------+-----------+
| % | sysbench |
| localhost | mysql.sys |
| localhost | root |
+-----------+-----------+
3 rows in set (0.00 sec)
mysql> grant all privileges on *.* to 'sysbench'@'%' ;
mysql> flush privileges;
数据库环境准备完毕后，准备sysbench命令
sysbench --test=oltp --db-driver=mysql --oltp-table-size=1000000 \
--mysql-db=sysbench --mysql-user=sysbench --mysql-password=sysbench \
prepare
自动产生的测试表的样子

4 Phoronix测试套件
Phoronix测试套件简称pts,从官网http://phoronix-test-suite.com/?k=downloads下载安装包 phoronix-test-suite-7.0.1.tar.gz
pts的安装依赖php-cli等多个包
tar xvf phoronix-test-suite_6.2.2.tar.gz
cd phoronix-test-suite/
./install-sh
/usr/bin/phoronix-test-suite list-available-suites
/usr/bin/phoronix-test-suite list-available-tests
phoronix-test-suite info pts/disk
phoronix-test-suite install pts/iozon
phoronix-test-suite install pts/disk
pts/disk包括了fio iozone aio-stress等等多个工具，pts太过庞大，install时因为网速原因，耗时较长。这里只使用一个iozone做个测试。
使用pts套件运行iozone
[root@node1 ~]# phoronix-test-suite run pts/iozone-1.8.0

5 IOzone的安装和使用
官网 http://iozone.org/
官方帮助文档 IOzone_msword_98.doc
下载安装包 [Stable tarball] iozone3_465.tar
安装过程
150 mkdir test_iozone
151 mv iozone3_465.tar test_iozone/
152 cd test_iozone/
153 ls
154 tar -xf iozone3_465.tar
155 cd iozone3_465/src/current/
156 ls
157 make
158 uname -a
159 make linux-AMD64
160 yum provides cc
161 yum install -y gcc
162 make linux-AMD64
163 ll
164 ls -ort
165 date
166 iozone
167 ./iozone
168 ./iozone -h
169 ./iozone -Ra -g 8G -i 0 -b iozone.xls这个输出到xls文件
运行命令
./iozone -Ra -g 8G -i 0 这个输出到屏幕
iozone产生的结果比较直观地看到不同块大小和不同文件大小对IO的影响。
