Download the latest version of WordPress to your computer and unzip the files.

(e.g. wordpress-4.9.8.zip) to a location where you can find them again.

Next, open your FTP client (e.g. FileZilla) and connect to your webspace with the FTP access data, then search for the folder you have unpacked. Now select the folders and 

Files from Wordpress that you can find in the wordpress directory.

Copy folders and files to the selected main directory, which is normally /htdocs. Wait until the transfer is complete.

Now open your browser and enter your domain name, if everything ran correctly, you will find at this point a page that looks like the one in the picture below. Click here on "Create configuration file" to start the installation.

In the next item, simply select "...you're ready to go!" to go to the next page.

Then the data of your MySQL database is queried. Here it is necessary to fill in the fields "Name of the database", "Name of the database user" and "Password", the rest remains. As the next point the hint for the start of the actual installation appears, which you must confirm here with "...let's

start the installation".

If an error should appear here, please check your MySQL access data.

The last step is to create a title for the page, a working e-mail address and a

username and password for the administration area of Wordpress. 

Shortly below, you can select whether the future blog should also be entered in search engines. 

Click on "Install WordPress" to complete the installation.

On the appearing page you will get the login and a specific password, which you need to log in to the administration page of your blog.

You have now installed WordPress and can log in at any time under your domain name plus "/wp-login.php" behind it (e.g. http://www.mustermann.de/wp-login.php) to make configurations on the site, or call up your domain name to view the blog.
