A new volume was added to hosting provided by https://hetzner.com located in /mnt/HC_Volume_5017960

When copying using dd, an incomprehensible error occurred (the process was interrupted) and the volume size became incorrect. I created a new directory in mnt and mounted the disk, now the disk size shows correctly, but now it is named /dev/sdd. How to delete a section /dev/sdс? it is impossible to unmount and read the section,restart the server I also can not.

# umount /dev/sdc
-bash: /bin/umount: cannot execute binary file: Exec format error

I have had a site I was working on running in /var/www/html for a while. I'm starting a new project and would like to run another site locally.

After some googling, I was checking out this previous question: https://ubuntuforums.org/showthread.php?t=1423044

I created a folder in /var/www called my-site and just cloned the git repo I will be using in there for the time being.

Then I added a file called my-site.com.conf to /etc/apache2/sites-enabled. Here's what it looks like:

<VirtualHost *:80>
ServerAdmin webmaster@localhost
    ServerName www.my-site.com
DocumentRoot /var/www/my-site/
<Directory />
    Options FollowSymLinks
    AllowOverride None
</Directory>
<Directory /var/www/my-site/>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride None
    Order allow,deny
    allow from all
</Directory>

ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
    AllowOverride None
    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    Order allow,deny
    Allow from all
</Directory>

ErrorLog /var/log/apache2/error.log

# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn

CustomLog /var/log/apache2/access.log combined

Alias /doc/ "/usr/share/doc/"
<Directory "/usr/share/doc/">
    Options Indexes MultiViews FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all
    Allow from 127.0.0.0/255.0.0.0 ::1/128
</Directory>

</VirtualHost>

I added the following to /etc/hosts:

127.0.0.1       www.my-site.com

I also ran the following command within /etc/apache2/sites-enabled:

ln -sf /etc/apache2/sites-available/my-site.com /etc/apache2/sites-enabled/my-site.com

The problem is that when I go in my browser to my-site.com, I am redirected to the old site that I had running on localhost before. My old site doesn't allow a user to go anywhere until they have logged in, and it seems like I am consistently being redirected to the login page.

How do I access my new site and set up an environment where I can work on both of these projects?

Let me know if I need to provide more information.

Thanks!

I've installed Ubuntu 10.04 LAMP server. The only (in addition to all the standard technical users created by installation) user is "administrator" (should I create more?). I doubt it is correct to place public websites to /home/administrator/public_html/. What is the correct place? I am going to use Apache's Name-based Virtual Host Support to host multiple websites.

I have been playing around with my blog, alot. I have couple of old computers laying around i want to put to use.

I was wondering if there is a way to setup a server, then will be linked to a url that i buy and server pages and maybe even install wordpress.

Any information on setting that up on Ubuntu 10.04 Desktop would be amazing.

Please and thank you.
