$sudo zypper install postgresql postgresql-server pgadmin3

Start server

$sudo rcpostgresql start

Change password for postgres user

$sudo postgres -c psql postgres
ALTER USER postgres WITH PASSWORD 'postgres';
\q

Error!

“IDENT authentication failed for user”

Hence, if you do not use IDENT, edit the /var/lib/pgsql/data/pg_hba.conf file and change “ident” to “md5″. Say, for instance, the lines below

local all all ident
host all all 127.0.0.1/32 ident
host all all ::1/128 ident

to

local all all md5
host all all 127.0.0.1/32 md5
host all all ::1/128 md5

Once done,restart postgreSQL as follows:

opensuse:~ # rcpostgresql restart

Create and Delete users

To create an user

opensuse:~ # su postgres

postgresql@opensuse:~> createuser -D

for user with password

postgresql@opensuse:~> createuser -D -p

To delete user

postgresql@opensuse:~> dropuser

The one I downloaded was: jdk-7u2-linux-i586.rpm

Install the jdk with yast2, zypper, or by double clicking the rpm within dolphin or nautilus:

sudo zypper in jdk-7u2-linux-i586.rpm -y

Now you have to setup the alternatives so you can use switch between Iced Tea, which is default, and the Oracle Java.

First install the alternative:

sudo /usr/sbin/update-alternatives --install "/usr/bin/java" "java" "/usr/java/jdk1.7.0_02/bin/java" 40

Now install the alternative for your browser plugin:

sudo /usr/sbin/update-alternatives --install "/usr/lib/browser-plugins/javaplugin.so" "javaplugin" "/usr/java/jdk1.7.0_02/jre/lib/i386/libnpjp2.so" 40

Note: the first quotes are pointing to the path, the the name of the alternative script, and the 3rd is the location to point to. The numbers at the end is the priority in case it was set to automode.

Now you have to configure the alternatives, first we’ll do java:

sudo /usr/sbin/update-alternatives java

Choose the number associated with /usr/java/jdk1.7.0_01/bin/java, in my case it was 1.

Now lets configure javaplugin:

sudo /usr/sbin/update-alternatives javaplugin

Choose the number associated with /usr/java/jdk1.7.0_01/jre/lib/i386/libnpjp2.so, in my case it was 1.

First, for the haters. I do linux for a living on servers, so I’m used to sudo, and that’s why I use it on my laptop.

Second, also for the other haters. Yes, I could have added some super high priority and kept it on auto, but I like doing it manually.

For the rest, you can check to see what you currently have set by running:

/usr/sbin/update-alternatives --query (or --display) java (or javaplugin)

You can test your java at oracles website:

openSUSE 11.3 und höher

Zur Installation von TLP auf openSUSE müssen die folgenden Schritte in einer Root-Shell ausgeführt werden.

Hinzufügen von Repositories:

Paketquellen aktualisieren:

zypper ref

Folgende Pakete sind zu installieren:

• tlp (TLP Repo)
• tp_smapi-kmp-desktop (Contrib Repo) – optional nur für ThinkPads, ermöglicht das Einstellen der Akkuladeschwellen und erweiterte Statusanzeigen.

Hinweis: Paketname muss ggf. in tp_smapi-kmp-VARIANTE angepaßt werden, die Kernelvariante lässt sich mit uname -r ermitteln.

• smartmontools (openSUSE Repo) – optional, ermöglicht die Anzeige von SMART-Daten für die Festplatte(n) durch tlp-stat.
• ethtool (openSUSE Repo)- optional, ermöglicht es Wake On LAN zu deaktivieren.
• powertop (openSUSE Repo) – optional, zur Messung des Stromverbrauchs.

Die Pakete installiert man im Terminal als root mit folgendem Kommando (tp_smapi-Paketname ist ggf. anzupassen):

zypper in tlp tp_smapi-kmp-desktop smartmontools ethtool powertop

Then, do not forget to install gcc and kernel-source via zypper.

The most important:

sudo /usr/bin/vmware-modconfig  --icon="vmware-player" --appname=Vmware --gcc=/usr/bin/gcc --headers=/lib/modules/3.1.0-1.2-default/build/include/ --gcc-ignore-minor

Then it works well for me.

$sudo zypper install powertop
$sudo zypper install  laptop-mode-tools
$sudo zypper install cpufrequtils

also check out cpufreq-utils
http://forums.opensuse.org/blogs/jdm…ls-package-40/

Thanks, quota for remark see following:

I have written a bash script file designed to work with the cpufrequtils package and the programs cpufreq-info (for reading CPU speed info) and cpufreq-set (to set CPU speed governor and frequency).

This is my third attempt at writing a bash shell to interface with these two packages. After creating a blog on how to use YaST to set your CPU speed with yast-power-management you can read about here: YaST Power Management – Control Your CPU Energy Usage How To & FAQ – Blogs – openSUSE Forums, several forum users indicated they used the cpufreq utilities instead. So, I decided to see if any sort of value added bash script could be put together to work with this program set. Changes made to your CPU speed only last until you reboot your computer, but you may find the information and function it provides to be useful.

Version 1.10 of C.F.U. (works with openSUSE 12.1) Adds new features and bug fixes:

1. New Help Display is included
2. C.F.U. includes menu automation. Type cfu -h for more details
3. Better Detection for the cpufrequtils to work and to be installed
4. Better detection of available speeds usable on your PC

To use the bash script file cfu, you need to download the following text from SUSE Paste (Actual Link is shown below) into a text editor like kwrite:

C.F.U. – CPU Frequency Utility – Version 1.10

Save the text as the file cfu in the /home area bin folder (example is: /home/username/bin, also known as ~/bin). It is possible to directly download cfu from a terminal session (You must delete or rename the old version first):

rm ~/bin/cfu

wget -nc http://paste.opensuse.org/view/download/72458191 -O ~/bin/cfu

This script must be marked executable to be used. Please run the following Terminal command:

chmod +x ~/bin/cfu

It is even possible to string all three of these commands together as one. Copy the following command, open up a terminal session, paste it in and press enter:

rm ~/bin/cfu ; wget -nc http://paste.opensuse.org/view/download/72458191 -O ~/bin/cfu ; chmod +x ~/bin/cfu

To use cfu, open a terminal session and type in:

cfu <OR> cfu -h

If the cpufrequtils package is not installed, you will be prompted to install it. In order to change your governor or CPU speed, you must supply the root user password. Same goes for installing the cpufrequtils package if it is missing. As always, I would love to hear about any comments or problems you might have using cfu.

Thank You,

download.

I hope you like it, we just have life only one time.
