#2002 Cannot log in to the MySQL server

If you're getting "#2002 Cannot log in to the MySQL server" when logging in to phpmyadmin on mac os, try editing phpmyadmin/config.inc.php and change:

$cfg['Servers'][$i]['host'] = 'localhost';

to:

$cfg['Servers'][$i]['host'] = '127.0.0.1';

Did the trick for me (after spending 2 hours on it).

How To Install ruby-oci8 on Ubuntu Server 64bits

I’m running rvm so a couple things to note

remove sudo before building the ruby-oci8 gem

$ sudo env LD_LIBRARY_PATH=/opt/oracle/instantclient_11_2 /usr/bin/gem install ruby-oci8

just run

$ env LD_LIBRARY_PATH=/opt/oracle/instantclient_11_2 /usr/bin/gem install ruby-oci8

with rvm, you’ll need to specify your env before executing the sql.rb script from the tutorial

$ env LD_LIBRARY_PATH=/opt/oracle/instantclient_11_2 ruby sql.rb
