<pre>
# Guess Number

import random

# Компьютер придумывает число от 1 до 100
compnumber = random.randint(0,100)
print(compnumber)
attempt = 20
print("У вас {0} попыток чтобы отгадать число!".format(attempt))

for i in range(1, attempt) :
number = int(input('Введите число от 1 до 100: '))
if compnumber == number :
print ('Вы угадали! Поздравляем!')
break
else :
if compnumber < number :
print ('Мое число меньше!')
if compnumber > number :
print ('Мое число больше!')

</pre>

Задание: Модифицировать программу чтобы в конце сообщения с поздравлениями она выводила сообщение о количестве использованных попыток, а также выводило сообщение "Вы проиграли" в случае если количество попыток закончилось.

Дополнительно: модифицировать код таким образом, чтобы программа давала возможность пользователю сыграть еще раз (используйте цикл do while)

== Installation of a name-based virtual web server with PHP support ==

'''Task''': learn to set up and configure popular web servers Apache and Nginx

'''Conditions''': this praktikum assumes that the Linux server IP address is 192.168.1.136

Make sure that nothing is launched on port 80

<pre>sudo lsof -i :80</pre>

Update package list from the repositories
<pre>sudo apt-get update</pre>

Install the Apache web server
<pre>apt-get install apache2</pre>

Check which catalogues Apache was installed to
<pre>dpkg -L apache2</pre>

Search for the PHP module for Apache
<pre>apt-cache search mod-php</pre>

Install the PHP module
<pre>sudo apt-get install libapache2-mod-php</pre>

Create catalogues for virtual hosts
<pre>
sudo mkdir -p /var/www/example.com/public_html
sudo mkdir -p /var/www/test.com/public_html
</pre>

Recursively change the owner of directories
<pre>
sudo chown -R www-data:www-data /var/www/example.com/public_html
sudo chown -R www-data:www-data /var/www/test.com/public_html
</pre>

Change allowances for catalogue /var/www rwx r-x r-x
<pre>sudo chmod -R 755 /var/www</pre>

Create file index.html
<pre>sudo nano /var/www/example.com/public_html/index.html</pre>

Write the following:
<pre>
<html>
<head>
<title>Welcome to Example.com!</title>
</head> <body>
<h1>Success! The example.com virtual host is working!</h1> </body>
</html>
</pre>

Save and copy this file
<pre>sudo cp /var/www/example.com/public_html/index.html /var/www/test.com/public_html/index.html</pre>

Change the contents of the copied file
<pre>sudo nano /var/www/test.com/public_html/index.html</pre>

Change "example" to "test":

<pre>
<html>
<head>
<title>Welcome to Test.com!</title>
</head> <body>
<h1>Success! The test.com virtual host is working!</h1> </body>
</html>
</pre>

Save

Create file /var/www/html/index.php

<pre>sudo nano /var/www/html/index.php
</pre>
with the following contents
<pre>
<?php
phpinfo();
?>
</pre>

Save

Remove port 80 from the default host /etc/apache2/sites-available/000-default.conf
<pre><VirtualHost *:80></pre>

Copy the configuration file for the first virtual host
<pre>sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/example.com.conf</pre>

Change the content to the following
<pre>sudo nano /etc/apache2/sites-available/example.com.conf</pre>

<pre>
<VirtualHost *>
ServerAdmin admin@example.com
ServerName example.com
ServerAlias www.example.com
DocumentRoot /var/www/example.com/public_html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
</pre>

Copy this file to the virtual host directory
<pre>sudo cp /etc/apache2/sites-available/example.com.conf /etc/apache2/sites-available/test.com.conf</pre>

And change its contents
<pre>sudo nano /etc/apache2/sites-available/test.com.conf</pre>

<pre>
<VirtualHost *>
ServerAdmin admin@test.com
ServerName test.com
ServerAlias www.test.com
DocumentRoot /var/www/test.com/public_html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
</pre>

Activate the virtual hosts
<pre>sudo a2ensite example.com.conf</pre>

<pre>
cd /etc/apache2/sites-enabled
sudo ln -s ../sites-available/test.com.conf
</pre>

Check the configuration and restart
<pre>
apachectl configtest
sudo service apache2 restart
</pre>

Since we don't have a DNS server installed, write the IP address and names of our virtual servers manually in file /etc/hosts

<pre>
sudo nano /etc/hosts
</pre>

192.168.1.136 example.com
192.168.1.136 test.com

If we want to check this on a Windows machine, add these lines to the file
C:\Windows\System32\drivers\etc\hosts

Check the health of virtual servers by name

http://example.com
http://test.com

or by using curl in the Linux terminal or Windows browser
<pre>
curl -v http://example.com
curl -v http://test.com
curl -v http://192.168.1.136
</pre>

=====Installation of Nginx=====

Stop the Apache server since since it's not possible to keep 2 servers on the same port
<pre>sudo service apache2 stop</pre>

Install nginx
<pre>sudo apt-get install nginx</pre>

Go to catalogue
<pre>cd /etc/nginx/sites-available</pre>

Copy the default configuration file
<pre>sudo cp default nginx</pre>

Edit the config file
<pre>sudo nano nginx</pre>

The contents should look like this

[[File:SumCodeForLinux5.jpg|center left]]

Create html file with any content, such as «hello Nginx»
<pre>sudo nano /var/www/html/nginx.html</pre>

Go to the site activation directory
<pre>cd /etc/nginx/sites-enabled/</pre>

Remove the link to default site
<pre>sudo rm default</pre>

Add the link to the new site
<pre>sudo ln -s /etc/nginx/sites-available/nginx</pre>

Check nginx syntax
<pre>nginx -t</pre>

Restart nginx
<pre>sudo service nginx restart</pre>

Check
<pre>curl -v http://192.168.1.136</pre>

===== Simultaneous use of Apache and Nginx =====

<pre>sudo nano /etc/apache2/ports.conf</pre>

<nowiki>#Listen 80 </nowiki>

<nowiki>Listen 127.0.0.1:81 </nowiki>

Save changes

Make sure that all Apache's configuration files have
<VirtualHost *>

Restart nginx
<pre>sudo systemctl restart nginx</pre>

Initiate apache
<pre>sudo systemctl start apache2</pre>

We can make sure that each port is listening
<pre>sudo netstat -nlpt | grep :8[01]</pre>

[[File:SumCodeForLinux6.jpg|center left]]

Check whether Apache works through 127.0.0.1 with curl
<pre>
curl http://127.0.0.1:81
curl http://127.0.0.1:81/index.php
curl -H 'Host: example.com' http://127.0.0.1:81
curl -H 'Host: test.com' http://127.0.0.1:81
</pre>

Edit the nginx configuration file so that all requests on port 80 redirected to apache

<pre>sudo nano /etc/nginx/sites-available/nginx</pre>

[[File:SumCodeForLinux7.jpg|center left]]

Restart nginx
<pre>sudo systemctl restart nginx</pre>

Listen to port 81 on a local interface
<pre>
sudo apt-get install ngrep
sudo ngrep -W byline -d lo "" port 81
</pre>
At the same time, on a different machine, try to open the sites test.com, example.com and 192.168.1.136

Now apache will respond to all requests

''Server: Apache/2.4.18 (Ubuntu).''

Add these lines to the config nginx file before location /
<pre>sudo nano /etc/nginx/sites-available/nginx</pre>

[[File:SumCodeForLinux8.jpg|center left]]

<pre>sudo systemctl restart nginx</pre>

Listen to port 80 on interface c
<pre>sudo ngrep -W byline -d enp0s8 "" port 80</pre>

At the same time, on a different machine, try opening the html file 192.168.1.136/nginx.html
Now all the requests with an html file in the address will be handled by nginx

''Server: nginx/1.10.0 (Ubuntu).''
