Server :: Debian Lenny - All Virtual Hosts Lead To First Virtual Host

Apr 21, 2010

I'm having an issue with setting up the virtual hosts on my web server. I have 2 virtual hosts (example1.com, example2.com). example1.com works but example2.com is sent to the index file of example1.com. I did some searching on google and it seems the problem might be with my /etc/hosts file.

First virtual host that the second is also directed to...in sites-available/sites-enabled (note port 80 is blocked by my isp so I use 8080)

Code:

Second virtual host file

Code:

And my hosts file

Code:

# The following lines are desirable for IPv6 capable hosts

Also I'm using a dyndns.org...would that make a difference?

CentOS 5 :: Create Virtual Machine From Existing Image?

Jan 3, 2011

I had set up 4 virtual machines on centos 5.5 system where I directed the image locations to an external storage. I have lost the image files in the storage, but I have the image files that were copied from the virtual machine image location. I want to put up the same system on the same computer by copying these backup images. However, when I copy the image file to the same exact location and start the corresponding virtual machine I get "no bootable disk" error. When I increase the size of the image using "qemu-img" commands, I can get rid of this error, but get "error reading disk" error. Is there a way to overcome these problems, or is it not possible to restore a virtual machine by copying the machine image file under ..../xen/images?

CentOS 5 Server :: Cloning An Existing Installation?

Feb 16, 2009

is there a way to clone an installation? I have a couple "master systems" which I want to replicate into other servers. In Solaris I can build a flar image from the first one and install from that image, I looked into cobbler and koan, but they seem to be more repo and kickstart oriented.I need a way to say "take this system as a base and build an installation image out of it".

Debian Installation :: None Of Existing Partition Visible

Feb 14, 2011

I am trying to replace an existing ubuntu installation with the current debian testing release. But when it comes to select partitions to install on none of the existing partitions is visible. I only see my SATA hard drive empty. The existing installation of Windows is still bootable and fdisk as well as cfdisk correctly recognize the partition table while parted (which I assume is used by the installation process; all tools run from a live cd) is not:

[root@localhost liveuser]# cfdisk /dev/sda
cfdisk (util-linux-ng 2.18)
Disk Drive: /dev/sda
Size: 160041885696 bytes, 160.0 GB
Heads: 255 Sectors per Track: 63 Cylinders: 19457 .....

[root@localhost liveuser]# parted /dev/sda unit s print
Error: Can't have overlapping partitions.

I am not sure what parted's error message means. I can hardly imagine that it complains about the logical partitions with in the extended one. The reasons for the trouble might come frome the fact that sda4 is marked as primary partition (see cfdisk output). If this is the case, how can I repair this?

Debian Installation :: Jessie Installer Cannot See Existing Linux Partition

Jan 12, 2016

I have an issue with Gparted v0.19.0 (Jessie) which has replaced v0.12.1 (Wheezy) which works fine. I had hoped to ask this question in Gparted's own forum, but after three weeks and multiple attempts no-one has approved my account there.

Unfortunately, my existing partition structure (on two different laptops) seems to be invisible to the new version of Gparted. Since parted seems to be used by the Debian installer, the Jessie installer cannot install on these machines without repartitioning the entire disk. That means that on such machines, the only option is to wipe everything or install Wheezy, then edit sources.list to upgrade to Jessie.

Both Gparted v0.19.0 and the Jessie installer report the entire hard disk as a single Fat16 partition,The same partitions which are invisible to Gparted appear as normal in the Places sidebar, of either Thunar or the PCManFM file manager. They can be mounted and used, seemingly without issue (I have experienced the same problem under Ubuntu/Lubuntu 15.10). Below, is the shell output of fdisk, which can see the partition structure and parted, which cannot:

Code: Select all$ sudo fdisk -lu

Disk /dev/sda: 74.5 GiB, 80026361856 bytes, 156301488 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

[code]...

Debian Installation :: Install Jessie Alongside Win8 On Existing LUKS / LVM Disk

Sep 8, 2015

I'm trying to upgrade my Win8/Wheezy 64-bit machine to Jessie 8.1 by installing from the amd64-bit netinstall iso image on a USB flash drive. I had done the previous, Wheezy, install on a disk partition that was whole-partition LUKS/LVM drive, with separate logical partitions for swap, root, and home.

Before doing the upgrade, I booted to the BIOS to ensure that my UEFI system had the correct, CSM and Legacy modes enabled in it, so that installer would boot using the non-efi BIOS mode.

Step one of the upgrade was to boot the netinstall and enter the rescue mode so that I could manually do the cryptsetup/LVM business. When I returned to the installer, I mounted the now-recognized logical partitions normally, choosing to format only the swap and / partitions.

During the entire process, I had to go into rescue mode one more time to manually mount the unencrypted /boot partition, along with my /home partition. I copied a backup of my old /etc/crypttab from the latter, and after returning to the installer, finished the install. That finish included installing grub on my hard drive's main boot partition.

Everything seemed to finish with no problems. However, when I try to boot the debian bootloader, I get tossed to grub rescue with the message that '/grub/x86_64-efi/normal.mod' doesn't exist. At this point I returned to the installer, mounted the /boot partition, and saw that there grub-install didn't create that an x86_64-efi directory at all. Instead, it had created an i386 directory. The exact name escapes me at the moment.

I *think* that my install was clean other than the last bit that was related to installing the bootloader. How to reinstall the bootloader in such a way as to make all of this work.

CentOS 5 :: P2V Conversion - Convert A Physical Box To A Virtual One

Apr 2, 2009

I've read several write ups on how to convert a physical linux box to a virtual one, but have yet to do it. I've tried a few times just playing around with no success. Generally I use VMware ESX as my host of choice, but am open to citrix's XEN (as citrix presentation server is my day job). I run 3 websites out of the house (on junk left over desktop.. can't believe I've had such good (lucky) uptime). One of the sites was particularly difficult to set up, so I'd rather not ahve to do it over again. It's built on OScommerce (LAMP).. so it's a database server as well come to think of it. So.. what have you tried to convert with/to?

Ubuntu Installation :: Upgrade From Another Distro To Server - Migrating Existing LVM - No Encryption And No Software Raid

Mar 28, 2010

I want to upgrade from another distro to ubuntu server for a few reasons. The only problem is I have a lot of data that needs to survive. here is how my computer is setup. I've 5 drives on the computer,

A- 10gb drive for OS and swap only, no data

B,C,D,E - 4x 500 GB drives in a LVM. they make up one large drive with xfs and this volume has about 1.2 TB of data. there is nothing fancy on it, no encryption and no software raid of course the little 10gb drive can be formatted no problem, but the LVM needs to be migrated over intact.

Debian :: Debian Etch - Virtual Server - GUI?

Jun 18, 2010

I am renting a virtual server which is running Linux Debian Etch. I have access through the root account.

I am very new to virtual servers, and also very new to Debian Etch. I am happy I found this forum when trying to research on the Internet.

The things I need to know are:
- Comes Debian Etch with a GUI (graphical user interface) which I can use on the rented virtual server?
- And if not, I would like to ask the community here if there are any GUIs which I could install to that server, and how?

I want to be able to access the server in a much easier way than to have to type each command. I want to use that server to host domains, as soon as I am more self-confident with Debian Etch.

Debian Installation :: Moving Debian Install From Virtual Machine To Physical

Feb 20, 2010

I have been learning Debian by using a virtual machine. After fine-tuning my installation procedure, I decided to copy that installation to my physical system. The hard drive already has another Linux based system installed. I plan to dual boot.After copying files I updated fstab and menu.lst.The partition scheme between the virtual and physical environments are similar, but the partitions are not mapped exactly the same.Thus the Debian system on the physical hard drive fails to boot simply because the initrd is created for the root partition location on the virtual machine. The initrd created in the virtual machine is looking for the root file system on /dev/hda1 whereas on my physical drive the new location is /dev/sda7.How can I rebuild the initrd on the physical system? I started to use the installation DVD in rescue mode, but I did not get too far.

Debian Configuration :: Virtual Server Not Rebooting?

Jul 6, 2015

I have a rented vserver running at Strato [URL]. It came preinstalled with Debian 7. I upgraded it to Debian 8, what seemed to run fine, all services running. The problems came up when I tried to reboot the server to test the init system. It just does not come up, I cannot ping it, nothing. I can boot into the rescue system, mount the system partitions and chroot in to the filesystem. In this state I also can run my services, including apache2 and mysql. In the syslog I find nothing about the reboot. Now I need to reboot ino the normal system. I already tried to resume to sysvinit without success.

Debian Configuration :: Make Mailboxes For Each Virtual Host On Server?

Mar 1, 2010

I'm using Debian 5 with Exim 4 on my VPS. My purpose is to make mailboxes for each virtual host on my server. What do I have: 1. Exim is set correctly - receiving mail from [URL]... is successfull. 2. Mail for [URL]... is delivered, and the mail for [URL]... too. But [URL]... is the site written to /etc/hosts (it's localhost), and [URL]... is virtual host. But mail from both boxes writes to /var/mail/mail. Now what do I need: 1. Make mail for [URL]... store in [URL].... and mail for [URL].. store in www/Maildir. 2. Make mailboxes like [URL].... to receive mail by Thunderbird. 3. Set passwords for [URL]... and [URL]... (I don't want to enter my system user/root passwords).

I've installed Nginx-full on a debian jessie server and want to install Wordpress, but for some reason Nginx-full isn't being seen as providing the httpd virtual package, so wordpress insists on installing apache.

According to everything I can find, nginx-full provides the httpd virtual package and this shouldn't happen. Is this a bug?

Debian Configuration :: Both HTTP And HTTPS On Same Server? (Apache Virtual Hosts)

Oct 30, 2015

How to best manage both http and https pages on the same apache-server without conflicts. For example, if i have both 000-default.conf and 000-default-ssl.conf pointing to mydomain.com, and don't want users who visit mydomain.com without specifically type the https-prefix to be redirected to the https-page - how to handle users using browserplugins such as https-everywhere etc?

Another option would be to create a subdomain ssl.mudomain.com and have users who want to reach the ssl site to have to type ssl. I have tested several things with https everywhere enabled in my own browser, and it seems really hard to make this working the way i want, in one way or another i always end up getting redirected to the ssl-site automatically.

The reason i need this to work is because i run one site that i don't care much about SSL, that is the "official" part of that site, and i also host some things for friends and family on the SSL-part. This would not have been a problem if it wasn't that i use self-signed certificates for my ssl-site and the major user become afraid when a certificate-warning pops up in their browser and therefor leave the site.

Fedora :: Use Existing WIndows 7 As Guest Virtual Machine In Fedora 12

Apr 5, 2010

My company's default OS is Windows 7. I convinced my manager so that I could use Fedora 12, since I am mostly familiar with development environment in Fedora. However there are a few things I need in Windows 7, and I want to stop going back and forth in two OS'es in dual boot-up setting.

I've searched online for easy way to use the existing Windows 7 as guest virtual machine. I first tried VMware's Vcenter Converter Standalone in Windows 7, but it failed with some error code, and searching the particular error code didn't turn up any solution. I also tried to use Sun's VirtualBox, but I get segmentation fault error in Fedora. I tried to see if VMware server has a tool, but installation exists with an error, and searching the web for the error code didn't turn up anything either.... I wonder if I am having this much difficulties because I am using x86_64 version of OS'es.

Anyhow, if anyone has done it successfully - using existing Windows 7 as guest virtual machine in x86_64 version of Fedora 12.

Server :: Virtual LDAP Server And Virtual Mediawiki Host - Can't Login With Users From LDAP

Jun 5, 2011

In the past I found some great help on this forum, so here goes. Bare with me because it's a long story. I'll try to be as complete as possible. I've installed and configured OpenLdap on a virtual machine with ip 192.168.39.134. I've added 2 users via LAM. In the ou WikiUsers and the domain is wiki.local.

I've then created another host with ip 192.168.39.133 with mediawiki installed on it. Then I added the extension LDAPAuthenthication. In the LdapAuthentication file I added this code (only the last paragraph is mine, I added the others to show it's location in the script):

Quote:

$path = array( $IP, "$IP/includes", "$IP/languages" );
set_include_path( implode( PATH_SEPARATOR, $path ) . PATH_SEPARATOR . get_include_path() );

[code]...

I know I'm close because I can't register any new users or accounts on the mediawiki site. Although I could before I added the LDAP service. This is indeed all just to test and get to know how LDAP works. That's why it's all virtual in VMWare. I did not really configure anything on the LDAP, i just installed it and chose a domain (wiki.local).
