Boot-Installed-System

Some tips howto boot your not so bootable system using the DVD.

Once you are logged in then you can use
 yast2 bootloader 
 fdisk -l  to check for the bootable flag
 grub2-mkconfig /boot/grub2/grub.cfg 
 mkinitrd 

Good Luck folks!

Disable autorefresh

Disabling auto refresh of your repositories has some benefits. If you are on a limited internet connection or you just do not want to refresh every time you invoke zypper or yast sw_single then this post might be of interest for you.


Disable auto refresh for all remote repositories.
 zypper mr -R -t 

Now if you want to perform an update obviously you need to refresh the repositories. Here is a function that should help you do that. OpenSUSE defaults to bash for the log-in shell so you can just add this to your /etc/bash.bashrc.local  note that  bashrc.local does not exist and needs to be created.

update () {
## Check if user is root, if not exit with an error.    
if (( EUID !=0 )); then
  echo 'Root privileges are required for refreshing system repositories.' 1>&2
  return 1
fi

## Create an array from the enabled repos by parsing zypper lr.    
enabled=()
while IFS="|" read -ra line; do
  [[ ${line[3]} = *Yes* ]] && enabled+=("${line[0]// /}")
done < <(zypper lr) 

## Refresh all enabled repos and update.   
zypper ref "${enabled[@]}" && zypper up
}

After you have save it you can source bashrc.local run:    source /etc/bash.bashrc.local      and then you can just run:    update 


One question might arise if you change you're log-in shell into something more advance. Don't worry you can just create a bash script and name it    update   (or whatever name you like) and modify that function like this.

#!/bin/bash

## Check if user is root, if not exit with an error.
if (( EUID !=0 )); then
  echo 'Root privileges are required for refreshing system repositories.' 1>&2
  exit 1
fi
 
## Create an array from the enabled repos by parsing zypper lr.
enabled=()
while IFS="|" read -ra line; do
  [[ ${line[3]} = *Yes* ]] && enabled+=("${line[0]// /}")
done < <(zypper lr)
 
## Refresh all enabled repos and update.  
zypper ref "${enabled[@]}" && zypper up

Put it in say   /usr/local/bin  or any place that you are comfortable with. Make it executable
  chmod +x update  Then you can just run   update . 

Happy updating!

Vboxwebsrv with systemd on openSUSE

This works if you need to restart vboxwebsrv using systemd in openSUSE. Some folks  will raise some eye browse with this configuration for sure :-). The USER-NAME in the entry below is the username of the user who will access vboxwebsrv.



Create a unit file in /etc.

•  /etc/systemd/system/VBoxWeb.service 

why etc? because according to the man pages somewhere that if a local admin will make a unit file it should be in /etc because the order of which the unit file to be executed. Meaning if you have conflicting unit files in /usr and in /etc then the latter will be prioritize. Note that packages (*.rpm) unit files are in /usr.


Put the entry below inside that unit file.

 [Unit]
 Description=VirtualBox Web Service
 After=network.target

 [Service]
 Type=forking
 PIDFile=/run/VBoxWeb/VBoxWeb.pid
 EnvironmentFile=/usr/lib/systemd/system/VBoxWeb.service
 ExecStartPre=/bin/bash -c 'if [[ -e $PIDFile ]]; then rm -f "$PIDFile"; fi'
 ExecStart=/usr/bin/vboxwebsrv --pidfile "$PIDFile" --background
 Restart=on-failure
 User=USER-NAME
 Group=vboxusers

 [Install]
 WantedBy=multi-user.target

 This is not a shell script! That is what systemd folks will say for sure ;-). The ExecStartPre in that unit file is removing (deleting) the pid file so when vboxwebsv should restart  you will not get any errors. The EnvironmentFile entry is like sourcing a shell script. In this case it is sourcing the unit file itself, hence the variable PIDFile. Note that with systemd 208 which is the default fro 13.1 the ExecPre line in that unit file is not required anymore, seems systemd is much smarter now a days! :-). 12.3 below you might still need it.


Create the temporary files and directories.

•  echo "d /run/VBoxWeb 0755 USER-NAME vboxusers" > /etc/tmpfiles.d/VBoxWeb.conf 

•  mkdir /run/VBoxWeb 

Change the permission.

•  chown USER-NAME:vboxusers /run/VBoxWeb 

•  chmod 755 /run/VBoxWeb 

Disable the vboxwebsrv service that came with VirtualBox package.

•  chkconfig vboxweb-service off 

or

•  systemctl disable vboxweb-service.service 

Start your newly created (unit file)  Daemon.

•  systemctl start VBoxWeb.service 

Enable your newly created (unit file)  Daemon.

•  systemctl enable VBoxWeb.service

This is very useful when you are using phpvirtualbox and you are restarting the vms every once in a while.


Cheers...

VirtualBox Autosave Autostart of vms

This assumes that you are the only user on your system if not then you can try my Phpvirtualbox  guide. You do not need your favorite sudo utility nor running su just to set your vms to auto. Enable the systemd service one time and use VBoxManage to set your vms to auto.

 Download the script that will handle the vms.

•  wget https://raw.github.com/Jetchisel/VBoxAutostart/master/systemd-vboxinit 

Copy it to your ~/bin directory.

•   cp -v systemd-vboxinit ~/bin   

Make it executable.

•  chmod ug+x ~/bin/systemd-vboxinit 

Change the group to vboxusers

•  chgrp vboxusers ~/bin/systemd-vboxinit 

2. Download the unit file that will execute your script during boot/restart/shutdown of the host.

•  wget https://raw.github.com/Jetchisel/VBoxAutostart/master/VBoxAutostart@.service 

Replace The ExecStart and ExecStop part with your "$HOME"/bin as the PATH

•  cp -v VBoxAutostart@.service /usr/lib/systemd/system 

 Start that service.

•  systemctl start VBoxAutostart@your-user-name.service 

Enable it .

•  systemctl enable VBoxAutostart@your-user-name.service 

Check the status.

•  systemctl status VBoxAutostart@your-user-name.service 

your-user-name is your user name not mine :-)

 3. Choose your vms that you want to autostart and autosave during boot/restart/shutdown of your host.

Get the names of the vms.

•   VBoxManage list vms  

Set it to auto so the script will handle the autostart and autosave of the vm.

•  VBoxManage setextradata YOUR-VM-NAME pvbx/startupMode auto 

Get the status.

•   VBoxManage getextradata YOUR-VM-NAME pvbx/startupMode 

 Set it to manual if you dont want your vms to be handled by the script.

•  VBoxManage setextradata YOUR-VM-NAME pvbx/startupMode manual 

Set it to empty 'No value' the same thing it will be ignored by the script.

•   VBoxManage setextradata YOUR-VM-NAME pvbx/startupMode 

•   You can use the ExtraData script from the zip file below to manage your vms. 

4. To access your vms.

•  rdesktop localhost:1234 

where 1234 is the port number which you can set via the gui or via VBoxManage.

A gui app which you can use is krdc for Kde and   gnome-rdp for Gnome.

The zip file from github. https://github.com/Jetchisel/VBoxAutostart/archive/master.zip

I have package this stuff and it's in OBS now as an rpm. Look for systemd-vboxinit

 NOTE: if you have the Phpvirtualbox solution then you do not need this thus it can conflict with each other.

PhpSysInfo

Download the latest release in  http://sourceforge.net/projects/phpsysinfo/files/latest/download 

Unpack that tar ball. I choose to install in /data/apache2.

•  tar -zxvf phpsysinfo-"$version"-tar.gz -c /data/apache2

Set up sysinfo.

•  cd /data/apache2/phpsysinfo-"$version" 

•  cp -v phpsysinfo.ini.new phpsysinfo.ini 

Set permission.

•  chown -Rv wwwrun:www /data/apache2/phpsysinfo-"$version" 

Add an entry to apache2 config

•  vi /etc/apache2/conf.d/phpSysInfo.conf 

Add the entry below

  

  Alias /sysinfo /data/apache2/phpsysinfo-"$version"

  <Directory /data/apache2/phpsysinfo-"$version">
     Options Indexes MultiViews FollowSymLinks
     Order allow,deny
     Allow from all
  </Directory>
 

Again the only thing to adjust to your set up is /data/apache2.

Restart apache2

•  systemctl restart apache2.service 

Type the url on your browser

•  localhost/sysinfo 

phpVirtualBox on openSUSE reloaded

phpVirtualBox home page has been moved from google to sourceforge it is in http://sourceforge.net/projects/phpvirtualbox/files/latest/download.  You will need to install VirtualBox since it is just a front end.  before you can use this app. Refer to my guide on how you can install vbox.  After you have installed vbox you will install a web server. We will use apache2 as an example. You can either use yast2 software management to install the lamp_server pattern and some php packages or use our friend zypper.

  In this setup i choose to install to a different directory than /srv/www/htdocs. So just in case something unrecoverable happens :P in my system i will not delete the directory where phpvirtuablox resides. Here i choose /data/apache2. You can put it any where you like just replace the config entry in apache2.

To install the packages using zypper

•     zypper in patterns-openSUSE-lamp_server php5-soap      

 Create an entry for apache2

•     vi /etc/apache2/conf.d/phpvirtualbox.conf   

The only thing you need to replace to meet your setup is    /data/apache2  the rest is as-is.

  Alias /phpvirtualbox  /data/apache2/phpvirtualbox

  <Directory   /data/apache2/phpvirtualbox>
     Options Indexes MultiViews FollowSymLinks
     AllowOverride All
     Order allow,deny
     Allow from all
  </Directory>

 Unpack that zip file using unzip into /data/apache2.

•   unzip phpvirtualbox-"$version".zip -d /data/apache2/ && cd /data/apache2 

Rename that file to just phpvirtualbox

•   mv -v phpvirtualbox-"$version" phpvirtualbox && cd phpvirtualbox 

Now rename the php file

•  mv config.php-example config.php 

Edit that config.php file and put the name of the user which uses virtualbox and the corresponding line and do it like this.

   

  
  var $username = 'jetchisel';                                  

  var $password = 'mypassword';

•   var $ location = 'http://127.0.0.1:18083';  

•  var $consoleHost = 'IP ADDRESS OF YOUR COMPUTER'; 

Create an file called virtualbox in /etc/default and put something like this.

  VBOXWEB_USER=jetchisel

Set permissions as root run the following commands.

•   chgrp -Rv vboxusers /data/apache2/phpvirtualbox  

•   chmod -Rv 775 /data/apache2/phpvirtualbox   

 Edit that config.php file, un comment out the following.

  
  var $startStopConfig = true;
  
  var $enableAdvancedConfig = true;
                                 

For the deprecated system V.

 Download the vboxinit for SuSE.

•  wget https://raw.github.com/Jetchisel/vboxinit/master/sysV-vboxinit -O vboxinit 

copy the script to /etc/init.d

•  cp -v vboxinit /etc/init.d/vboxinit 

set permission.

•  chmod u+rx /etc/init.d/vboxinit  

Enable init script.

•  chkconfig vboxinit on  

 Check the script if it is working

•  /etc/init.d/vboxinit {start|stop|restart|status} 

Enable the init scripts at boot time.

•   chkconfig vboxweb-service on 

Restart the init scripts as root run the following.

•  service vboxautostart-service restart 

•  service vboxweb-service restart 

For SYSTEMD

 Download the systemd version  for SuSE.

•  wget https://raw.github.com/Jetchisel/systemd-vboxinit/master/systemd-vboxinit 

You can save it to any place you want even in /home/user/bin. In this example i choose to put in  to /usr/lib/systemd/

•  cp -v systemd-vboxinit /usr/lib/systemd 

Set permissions

•  chmod ug+x /usr/lib/systemd/systemd-vboxinit 

•  chgrp vboxusers /usr/lib/systemd/systemd-vboxinit

Create a systemd unit  "vboxvmservice.service" (or any name that suits you)
inside /usr/lib/systemd/system and add the entry below: Replace " username " with the user that belongs to the vboxusers group.

  

       [Unit]
       Description=VBox Virtual Machine  Service
       Requires=systemd-modules-load.service
       After=systemd-modules-load.service
       Before=shutdown.target reboot.target halt.target     

       [Service]
       Type=oneshot
       User=username
       Group=vboxusers
       KillMode=none
       StandardOutput=syslog+console
       EnvironmentFile=/etc/default/virtualbox
       ExecStart=/usr/lib/systemd/systemd-vboxinit start
       ExecStop=/usr/lib/systemd/systemd-vboxinit stop
       RemainAfterExit=yes

       [Install]
       WantedBy=multi-user.target

                           

If you choose to save the systemd-vboxinit script in another path and not /usr/lib/systemd then you need to adjust the following entry.

•  ExecStart=/path/to/file/systemd-vboxinit start

•  ExecStop=/paht/to/file/systemd-vboxinit stop 

Start that newly created unit.

•   systemctl start vboxvmservice.service 

Enable the service at boot time.

•  systemctl enable vboxvmservice.service 

Enable the init scripts;

•  systemctl enable vboxweb-service.service 

Start and enable apache2.

•   systemctl start apache2.service 

•  systemctl enable apache2.service 

In your browser type the url below:

•   localhost/phpvirtualbox  

First log in:

•  username: admin 

•  password: admin  

After a log in you can add a user that can handle your vms.

Configure vms in phpvirtualbox's graphical menu.

•  Settings --> General --> Basic --> "StartupMode --> Automatic" 

 An example of running vms at boot.

Checking the status of your unit after booting.

Zip file from github:  https://github.com/Jetchisel/systemd-vboxinit/archive/master.zip

You can search phpvirtualbox for an rpm package of this in OBS.

OpenSuSE on usb grub2

Since 12.2 release opensuse has grub2 as an option to use. Come 12.3 it is the default grub in the installation but you can always choose to use the old legacy grub. As of this time of my blog entry Aug 2013, grub2 is still in development but usable (so they say :P ).

Then if your using the old legacy grub  suse has some options to edit the necessary entry in order to boot your system when it has some boot issues.
Sadly if you use grub2 then it is only limited to the following:

As you can see theres a lot of missing files to be edited unlike old legacy grub.
Well some files were either renamed or removed completely. Grub2 has the following (but not limited to)  files:

1. /boot/grub2/.device.map
2. /etc/default/grub
3. /boot/grub2/grub.cfg
4. /etc/grub.d/

 If your going to do a usb install  then you should not follow the suggested partitioning from the installer since i may offer to use the existing internal partitions or worst suggest to delete it completely. Untick the "proposed separate home partition". Choose create partition setup and check your other partitions if they are mounted automagically by the installer if it is indeed mounted then umount it. The partitioning i suggest is to make the first part the root and if you really need a separate /home then put it in the second partition. A swap partition will be the last. Other wise you will be thrown at the grub prompt during the first reboot ;-(.



You will probablly will encounter some errors similar to  this.

This is to be expected, dont worry you can just copy the error somewhere.

Let it reboot after the installation and boot again from the dvd and choose installation in the menu. 

Once booted to your system you can  do the following commands.

echo '(hd0)  /dev/disk/by-id/ata.....' > /boot/grub2/device.map

Make sure you got the correct id of you disk.
----

  grub2-install --force /dev/sda1  

/dev/sda1 is my root partition so point it to yours.

Yo will get a WARNING but the important message is the last.

----


    grub2-mkconfig -o /boot/grub2/grub.cfg     

----
    /sbin/mkinitrd/     


Now if you will not see any errors from the last command then it is safe to reboot.

This hack is also true if you cloned your disk. This does not apply to efi system since i do not have any close encounter with EFI (at least not yet :P )

Enjoy folks!
