Installing MariaDB/MySQL system tables in ‚/var/lib/mysql‘ …
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
Two all-privilege accounts were created.
One is root@localhost, it has no password, but you need to
be system ‚root‘ user to connect. Use, for example, sudo mysql
The second is mysql@localhost, it has no password either, but
you need to be the system ‚mysql‘ user to connect.
After connecting you can set the password, if you would need to be
able to connect as any of these users with a password and without sudo
See the MariaDB Knowledgebase at https://mariadb.com/kb or the
MySQL manual for more instructions.
You can start the MariaDB daemon with:
cd ‚/usr‘ ; /usr/bin/mysqld_safe –datadir=’/var/lib/mysql‘
You can test the MariaDB daemon with mysql-test-run.pl
cd ‚/usr/mysql-test‘ ; perl mysql-test-run.pl

You may use the arp-table, or DHCP-leases. Not a perfect solution, maybe it’s enough?
List arp-table

Ubuntu redo apt
To clone your system to another system. Or make a backup. In terminal type:
dpkg --get-selections | grep -v deinstall > ubuntu-files
This command makes a file list of all installed packages in your system (and stores it in present working directory). Backup this file in hdd, email, etc…(this file is very small).
In the freshly installed ubuntu system run:
sudo dpkg --set-selections <./ubuntu-files (will set it up and)
apt-get -y update
apt-get dselect-upgrade
This will install only those packages you had installed (with apt-get
) in the old system.
(OR)
You could back up all the .deb
packages from /var/cache/apt/archives/
and install them manually using:
dpkg -i *.deb
And after that running an update cycle later.
