Preface
Under the background of the big data era, data storage has become the current pain point to solve. Major manufacturers have launched their own storage systems, such as Huawei, Tencent, Baidu, etc., although they have cloud services, cloud hosting and other upper-level application products. , But you still need a storage management system designed by yourself on the bottom layer.
This article is to explain the use of disk performance testing tools for storage systems and the writing of scripts
1. Installation of Fio tool on Centos7
1.1 Fio installation using yum
1.2 Fio source code installation (offline installation, download the package first) The method used in this article
For your convenience, I have uploaded the Fio tool, so you can download it yourself.
Download link: fio2.0.7 https://download.csdn.net/download/u013521274/12706795
Download link: fio3.7 https://download.csdn.net/download/u013521274/12706806
After the download is complete, you can use winscp and other software to copy the compressed package to a certain directory in Linux. Just drag and drop the VMware virtual machine.
Remarks: You must use the root user. Store the fio toolkit in the directory you created as shown below
1.1 Preparation before installation:
1. Fio requires gcc environment to run, check whether gcc is installed
2. Fio operation needs to rely on the package libaio to check whether it is installed
3. Yum may report an error when installing gcc. Check whether the Centos-Base.repo file is 0 bytes. If it is 0 bytes, you need to download a replacement (backup and replace)
Solution 3:
# cd /etc/yum.repos.d/
# ll -h
//两个命令查看
As shown above, we can see that the Centos-Base.repo file is not 0 bytes. If it is empty, you can download a file of the corresponding version and then replace it.

Note: Make a backup of the .repo file
Solution 2 :
Install libaio
执行 #yum install libaio
如果不行执行 #yum install libaio-develSolution 1:
Install gcc
#yum install gcc
或者
#yum install gcc-c++
1.2 Install FIO
#tar -zxvf fio-2.2.10.tar.gz
#cd fio-2.2.10
#./configure
#make
#make install
解压 编译 安装You can also refer to the following figure for installing fio
2. Use the Fio tool to write .sh scripts
Everyone can use notepad, notepad++ can write
#!/bin/sh
export test=fio
echo "第一个fio测试"
echo $(date +%F%n%T)
fio -directory=/fiorwtest -rw=write -bs=1M -direct=1 -iodepth 2 -ioengine=libaio -size 1G -thread -numjobs=2 -group_reporting -name=write1m_4job
echo $(date +%F%n%T)

Remarks: When scripts written in Windows are transferred to Linux for execution, sometimes errors will be reported because of some special characters.
Use #cat -A file to check for special characters
3. Execute the .sh file
#sh /etc/liy.sh
#bash /etc/liy.sh
//两种都行
