How to specify custom ssh key while git clone from github

Wed, 08 Feb 2017 05:33:57 +0000

If you need to provide some custom ssh key while cloning your repository from github (or pulling, whatsoever), run this command:

ssh-agent $(eval `ssh-agent -s`; ssh-add ~/.ssh/{your-custom-keyfile}; git clone git@github.com:{username}/{repo-name}.git .)

Please note, you should replace {strings} with plain string values!

Install proprietary Oracle JDK in Debian 7.0 Wheezy

Wed, 27 Aug 2014 07:29:58 +0000

This is a YAP (yet another post) about how one can manually install Oracle’s proprietary JDK/JRE version (in Debian 7.0 Wheezy as an example).

First of all, download fresh version of JDK/JRE from the Oracle website.

Copy archive to desired location, in the following example we will use

/usr/lib/jvm

as an installation source directory.

Unpack the archive and run next commands:

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk/bin/java 1071
sudo update-alternatives --install /usr/bin/javac javac /media/mydisk/jdk/javac 1071
sudo update-alternatives --install /usr/bin/jcontrol jcontrol /media/mydisk/jdk/bin/jcontrol 1071

You may need read man pages for update-alternatives to check out the parameters and what they mean.

How to add role to the PostgreSQL

Fri, 16 May 2014 09:15:01 +0000

If you need have superuser access to PostgreSQL via command line psql utility, create needed username first:

sudo -u postgres createuser NEEDED_USERNAME

You will be asked whether role should be a superuser:

Shall the new role be a superuser? (y/n)

answer “Y” (yes) if so and hit Enter.

Now you allowed the NEEDED_USERNAME to access databases as a superuser via psql.
