1、 Build a test website

compile LAMP Website deployment ：LAMP
web1 To configure ：
yum How to build a website

 initialization 
cd /etc/yum.repos.d/
yum install -y wget
wget http://mirrors.aliyun.com/repo/Centos-7.repo
wget http://mirrors.aliyun.com/repo/epel-7.repo
mv CentOS-Base.repo CentOS-Base.repo.bak
yum clean all
yum makecache
systemctl stop firewalld
systemctl disable firewalld
sed -i 's/SELINUX=enforcing$/SELINUX=disabled/g' /etc/selinux/config
setenforce 0

yum Way to build PHP The website is used for pressure measurement 
yum -y install httpd php php-mysqlnd php-gd
vi /var/www/html/index.php
<?php
phpinfo();
?>

 Modify the system file configuration 
vi /etc/security/limits.conf    Add at the bottom 
# Modify file open limit 
*                soft    core            unlimited

 Restart the device , Make system configuration effective 
ulimit -n     see limit Whether the configuration is effective 

systemctl start httpd
systemctl enable httpd

# see CPU Number 
cat /proc/cpuinfo |grep "physical id"|sort|uniq|wc -l
# see CPU Bus number 
cat /proc/cpuinfo |grep "processor"|sort|uniq|wc -l
# Look at the memory

# Check out the hard disk 
lsblk |egrep "^sd[a-z]"

web2 Build a website like the above , Do system configuration

3、webbench

webbench：Webbench It's a linux Under the use of a very simple website pressure testing tool . It USES fork() Simulate multiple clients accessing our settings at the same time URL, Test the performance of a website under pressure , You can simulate at most 3 Ten thousand concurrent connections to test the load capacity of the website .

GitHub Code ：webbench Source code
webbench Official website ：webbench
Compile and install the pressure measuring equipment webbench

yum install -y gcc ctags
wget http://home.tiscali.cz/~cz210552/distfiles/webbench-1.5.tar.gz

test 2 The performance of a website

 test web1
webbench -c 1000 -t 10 http://192.168.116.133/index.php

 You can see that when concurrency is 1000 when , Response requests per minute 38040 individual , The amount of data transmitted per second 38634276 byte 
Speed=38040 pages/min, 38634276 bytes/sec.

 The total number of requests is 6340 individual 
Requests: 6340 susceed, 0 failed.

 test web2, You can see that several values are better than web1 Much better 
webbench -c 1000 -t 10 http://192.168.116.134/index.php

 You can see that when concurrency is 1000 when , Response requests per minute 84474 individual , The amount of data transmitted per second 85981248 byte 
Speed=84474 pages/min, 85981248 bytes/sec.

 The total number of requests is 14079 individual 
Requests: 14079 susceed, 0 failed.

4、Windows Lower installation Apache-Jmeter

Apache JMeter Can be used to test static and dynamic resources 、Web The performance of dynamic applications .
It can be used to simulate servers 、 Server groups 、 Heavy load on network or object , To test its strength or analyze the overall performance under different load types .

jmeter need java Environmental Science , So you need to install java
download java：Windows-java8, Then directly open the installation

Select all default and next steps



Right click this computer and click Properties

Select advanced system settings

Choose environment variables

Select new system variable

Input java Installation directory , Set as variable

 Variable name ：JAVA_HOME
 A variable's value ：C:\Program Files\Java\jdk1.8.0_181

And then build a new one classpath Variable

classpath
.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar

Finally, find... In the system variable Path, Click edit , modify Path Variable

Create one more java route

stay Path add to

%JAVA_HOME%\bin
%JAVA_HOME%\jre\bin

Finally, restart the system , Let variables take effect .
Open after restart CMD, See if you can recognize java


install Jmeter
Download the package ：jmeter-5.2.1
Unzip the installation package and put it in C disc

New system variable
establish jmeter The path variable of

JMETER_HOME
C:\apache-jmeter-5.2.1

modify classpath A variable's value

 Change to the following 
.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar;%JMETER_HOME%\lib\ext\ApacheJMeter_core.jar;%JMETER_HOME%\lib\jorphan.jar

Double click the script to run jmeter
C:\apache-jmeter-5.2.1\bin\jmeter.bat

Change to Chinese

test web1
stay TestPlan Right click and select Add thread group

Set the number of threads （ Equivalent to the number of requests ）,Ramp-Up（ Total request time ）, No need to save , Go straight to the next step

And then right-click web1 Thread group

Enter the URL information

Right click again web1 Thread group , Add summary report

Click on the run

Prompt whether to save the operation plan , Direct selection no that will do

Wait a moment , You can see that web1 Website test results
You can see that the exception is 16.76%, Throughput for 220.6/sec
In general , The smaller the outlier, the better , The higher the throughput, the better , You can see web1 Performance ratio of web2 Bad

Follow the above steps to add web2 To test , View results
You can see that the exception is 19.84%, Throughput for 389.9/sec
In general , The smaller the outlier, the better , The higher the throughput, the better , You can see web2 Performance ratio of web1 good
