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
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
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

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

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

sysbench可以测试cpu \ oltp mysql\ fileio 网上用来测试mysql的文章比较多。
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
先掌握sysbench的语法
# sysbench

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]

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。

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

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
