Backup

Der Backup kann entweder von allen Datenbanken erfolgen:

sudo mysqldump --all-databases > /tmp/mysqldump.sql

mysqldump -u root -p --all-databases > /tmp/mysqldump.sql

oder mit nur eine Datenbank (Beispiel xwiki)

sudo mysqldump -u root -p xwiki > /tmp/xwiki.sql

Wiederherstellung

Wenn nur eine Datenbank wiederherstellt werden soll, dann muss die Ziel-Datenbank eingegeben werden:

mysql -u root -p --database=xwiki < /tmp/xwiki.sql

Weitere Information in https://dev.mysql.com/doc/refman/5.7/en/mysqldump-sql-format.html

Wie kann eine vorhandene VDI (Virtual Drive) Festplatte in Virtual Box vergrößern? In der GUI der Virtual Box (Version 5.1) gibt es keine Option. Die einzige mir bekannte Lösung ist VBoxManage.exe (C:\Program Files\Oracle\VirtualBox\VBoxManage.exe).

Der Aufruf erfolgt mit: VBoxManage.exe modifyhd "Absoluten Adresse zu VDI" --resize <neue Größe in MB>

Beispiel um eine vorhandene VDI Festplatte auf 40GB zu erhöhen C:\Program Files\Oracle\VirtualBox\VBoxManage.exe modifyhd C:\tomas\ubuntu\ubuntu.vdi --resize 40960

Weiteren VBoxManager Parameter :

Usage:

VBoxManage [<general option>] <command>
 
 
General Options:
 
 [-v|--version] print version number and exit
 [-q|--nologo] suppress the logo
 [--settingspw <pw>] provide the settings password

Die SSH Verbindung zu einem neuen frisch installierten OpenSUSE bzw. SLES ist nich möglich.

In der OpenSUSE Installation (Version 11) ist die Verbindung von externen Systemen über SSH nicht erlaubt.

tomas@ubuntu:~$ ssh -vvvv root@sles1
OpenSSH_7.2p2 Ubuntu-4ubuntu1, OpenSSL 1.0.2g-fips  1 Mar 2016
debug1: Reading configuration data /etc/ssh/ssh_config

debug1: connect to address 10.0.2.7 port 22: Connection timed out
ssh: connect to host sles1 port 22: Connection timed out

Schritte:

1. Verifiziere das auf dem OpenSUSE System die Firewall für SSH geöffnet ist.  $ iptables -nL | grep 22 soll Ergebnisse liefern:
2. Öffnen Firewall für SSH Daemon $ yast firewall und navigiere Allowed Services -> Service to Allow -> Secure Shell Server -> Add -> Next -> Finish

Um sich als root auf dem OpenSUSE Sever mit angaben von Passwort anmelden zu können, muss dies in ssh erlaubt sein (Eintrag PermitRootLogin yes).
$ vi /etc/ssh/sshd_config
