GITHUB bez hesla

Create a new repository, or reuse an existing one.

Generate a new SSH key:

ssh-keygen -t rsa -C "your_email@example.com"

Copy the contents of the file ~/.ssh/id_rsa.pub to your SSH keys in your GitHub account settings (https://github.com/settings/keys).

Test SSH key:

$ ssh -T git@github.com
Hi developius! You've successfully authenticated, but GitHub does not provide shell access.

Change directory into the local clone of your repository (if you’re not already there) and run:

git remote set-url origin git@github.com:username/your-repository.git

Now try editing a file (try the README) and then do:

$ git commit -am "Update README.md"
$ git push

You should not be asked for a username or password. If it works, your SSH key is correctly configured.

Recover your MySQL password

What if you’ve forgotten your MySQL root user password? This could be quite the predicament … had the developers not thought of that eventuality. In order to recover the password, you simply have to follow these steps:

Stop the MySQL server process with the command sudo service mysql stop
sudo mkdir /var/run/mysqld
sudo chown mysql:mysql /var/run/mysqld
Start the MySQL server with the command sudo mysqld_safe –skip-grant-tables –skip-networking &
Connect to the MySQL server as the root user with the command mysql -u root

At this point, you need to issue the following MySQL commands to reset the root password:

mysql> use mysql;
mysql> update user set authentication_string=password('NEWPASSWORD') where user='root';
mysql> flush privileges;
mysql> quit
