Dear Readers,

This is my first blog about how to install python on Windows. Please find the below details for the same.

System Requirements check:

Go to Settings-->About

Example
OS: Windows 10 Pro
System Type: 64-bit operating system (Choose accordingly while downloading)

*Installing Python on Windows 10 Guide:*

1. Search on Browser: python install on windows
2. Select website: https://www.python.org/downloads/
3. Go to Downloads Section: Choose Windows OS

Always download Stable release eg: " Python 3.12.4 - June 6, 2024 "
This Python 3.13.0b3 "b" indicates its beta version means its still in testing.

1. Python 3.12.4 Download Windows installer (64-bit) [ .exe file gets downloaded]
2. Then double click .exe file to install python

****Shows 2 options:

i. Install Now

ii. Customize installation

****Check boxes with 2 option below: (You can tick this check boxes)

i. Use admin privileges when installing py.exe
ii. Admin python.exe to PATH

*Then Choose Customize installation and all checkboxes can be selected. (as per your requirement)
Click Next
* Shows Advanced Options
i. Install Python 3.12 for all users
ii. Associate file with Python (requires the 'py" launcher)
iii. Create shortcuts for installed applications
iv. Precompile standard library
v. Download debugging symbols
vi. Download debug binaries(requires VS 2017 or later)

**Check box can be selected from i to v

Customize install location
By default it shows C.// drive (Keep as it is)
**Then it asks for Do you want to install on your device Click Yes. Shows Setup Progress
6.After successful installation it shows "Setup was successful".

Then click Close.

To verify python installed on machine or not:
Go to cmd / Command Prompt on your device

Once opened it shows as eg: C:\Users\Dev>
i. Type: python --version (example C:\Users\Dev>python --version)
ii. Shows output as below:
Python 3.12.4
If the above current version you installed shows its successfully installed.
To check for py shell
i. Type py (example C:\Users\Dev>py)
ii. Shows as below:

Here also you can type and check:

print("My first blog about python installation on windows....")
It shows as output below:
My first blog about python installation on windows....

You can also save your file:

File-->Save As and save with file name eg: demo. Automatically it gets saved as demo.py

You can open the file Notepad/Notepad++ editor to check it.

Thank you!

https://www.python.org/downloads/

check the system type of yours.
The latest series will not work on win 7 or earlier

*IDLE, an integrated development environment (IDE) for Python, to write and execute Python scripts. *

*Choose File --> New File *

Type the code & Save the file

Same above can be achieved in as below as well

SSH, also known as Secure Shell or Secure Socket Shell, is a network protocol that gives users, particularly system administrators, a secure way to access a computer over an unsecured network.

By default SSH is installed in linux.We can check the version by using this below command.

ssh -V

Otherwise we can install it by..,

sudo apt install openssh-server openssh-client
sudo systemctl status ssh

Also we can check the status of SSH.The default Port Number assigned by ssh is 22.We can change it in the configuration file also we can allow or deny users or groups and Alive Interval in the configuration file.
NOTE :
Restart the ssh after configured.

nano /etc/ssh/sshd_config

AllowUsers user_name
AllowGroups group_name

To allow permissions to specific users and groups to access ssh.

DenyUsers user_name
DenyGroups group_name

To deny the permission to specific users and groups.

LoginGraceTime specify_time

(i.e) 1m ==> 1 minute.
If a user can’t make a successful login with the specific time,it will not allow the user to enter into the remote machine.

ClientAliveInterval 600
ClientAliveCountMax 0 ==> Default it is zero.

(i.e) 600 ==> 600 seconds = 10 minutes.
The tunnel will break after the mentioned time (600 seconds) if there is no actions were performed by the user in the server.

NOTE: Restart the service once changes are made in configuration file.

ssh user_name@remote_ip
ssh user_name@remote_hostname -p port_number

To connect to the ssh server we must need three credentials of the remote machine.

• Username.
• Password.
• Ip Address or Hostname.

scp file_to_transfer user_name@hostname:/path_to_copy_the_file_in_remote_server

scp -P specific_port_number file_to_transfer user_name@hostname:/path_to_copy_the_file_in_remote_server   ===> For using Port Number other than 22.

Example : scp hello.go student@ip_address:/home/student/Checking_scp_command/
scp -P 2027 hello.go student@ip_address:/home/student/Checking_scp_command/

SCP ==> Secure Copy.
To copy a file securely to the remote server’s directory named “Checking_scp_command”.

scp user_name@hostname:/path_of_the_file/file /path_to_copy_in_local_system

scp -P specific_port_number user_name@hostname:/path_of_the_file/file /path_to_copy_in_local_system      ===> For using Port Number other than 22.

Example : scp student@ip_address:/home/student/Checking_scp_command/Remote_to_Local.txt /home/g/Downloads/
scp -P 2027 student@ip_address:/home/student/Checking_scp_command/Remote_to_Local.txt /home/g/Downloads/

In this command,we are going to get the file from remote server to our local system.

NOTE:

There is a command called “ssh-keygen” which generates a unique key for accessing the remote server via local system.
This never ask passwords to enter into the system,But be careful of handling this key.If you are not familiar with this method,just practice with the password type few times.
Keygen will be discussed later in our next post.Stay tuned…

That’s it..!

Let us know how to install wordpress in debian linux with the command line.
First,we need to create a database for a new user mainly for wordpress in mariadb.
Start the Apache server and mariadb service.Switch into mariadb then create a new user,which is already we discussed in mariadb installation.

I created a unique Database named “database_wordpress” specially for wordpress,also i created a new user.

wget https://wordpress.org/latest.zip
unzip latest.zip 
sudo mv wordpress/ /var/www/html/
sudo chown www-data:www-data -R /var/www/html/wordpress/
sudo chmod -R 755 /var/www/html/wordpress/
sudo nano /etc/apache2/sites-available/wordpress.conf

<VirtualHost *:80>
ServerAdmin admin@example.com
DocumentRoot /var/www/html/wordpress
ServerName <server_ip>
<Directory /var/www/html/wordpress/>
Options FollowSymLinks
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

These content must be written in the wordpress.conf file.
NOTE: Replace “localhost” in the pace of <server_ip> (4th line).

sudo systemctl reload apache2
sudo a2ensite wordpress.conf
sudo a2enmod rewrite
sudo systemctl restart apache2
rm latest.zip

You have successfully installed wordpress,by checking it open a browser and pass the url as “localhost” it will displays the wordpress page containing language selection dropdown.

That’s it…

Let’s know the installation of mariadb in debian.

sudo apt update
sudo apt install mariadb-server mariadb-client

First of all,we need to update the package manager and then type the install command.

Here we are going to install two packages i.e.., for server side and client side.You can skip the “mariadb-client” if you don’t need.

sudo systemctl status mariadb.service

Using this command,we can check the status of mariadb.Refer the image.

Now,we successfully done with the installation.After this we need to set a password to the root user.Because,by default the root user doesn’t have any password.So,we need to use this command..,

sudo mysql_secure_installation

Simply,press enter and then press ‘N’ next press ‘Y’ for further steps.

Also,you can create a new user.Let’s see how to create a new user.

CREATE USER 'your_username'@'localhost' IDENTIFIED BY 'your_password';

GRANT ALL PRIVILEGES ON *.* TO 'your_username'@'localhost' WITH GRANT OPTION;

FLUSH PRIVILEGES;

User has been created.

Let’s enter into mariadb.

mariadb -u your_username -p

NOTE: Don’t pass “@localhost” here.Simply pass username only.

Now,enter the created password.

If the output displayed like this,you were done…

SHOW DATABASES;

Here,we can see the databases.

We can discuss it later on MySQL topics.

EXIT;

Exit from mariadb.

sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf

Getting this configuration file,we can change some configuration.

NOTE :

After configure,we must restart the mariadb.

sudo systemctl start mariadb.service
sudo systemctl stop mariadb.service
sudo systemctl enable mariadb.service
sudo systemctl disable mariadb.service
sudo systemctl restart mariadb.service

We can use these commands as per our convenience like we discussed in Apache installation.

Here,we are going to discuss about how to install apache server in debian.

sudo apt update

sudo apt install apache2

Once,the packages are installed in your system.Run the server by the following command.

sudo systemctl start apache2

Now you can check the status whether it is running or not by using..,

sudo systemctl status apache2

Active: active (running) since Thu 2024-02-08 18:37:49 IST; 11s ago
You can check that it is running.Also there is a another method to check by entering http://localhost/ in any of your browser.

sudo systemctl enable apache2

If you don’t want to start every time and by default the server should be on running,use the above command.It starts automatically when the system boots.

sudo systemctl stop apache2

This command will stop the server.

sudo systemctl disable apache2

This will disable the server and is not running after the system boots.

Now,we can see how to remove apache server.

sudo apt remove --purge apache2

This will remove the apache2 server from your system.

sudo apt autoremove

This command is used to remove the apache related dependencies automatically from the system.

That’s it…
