How to redirect your website base on country ip request, Apache, geoip, rewrite

Install the mod-geoip

sudo apt-get install libapache2-mod-geoip

Enable the mods:

sudo a2enmod rewrite
sudo a2enmod geoip

In your file ".htaccess" add these lines:

# if country is PT
RewriteEngine on
RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^PT$
RewriteRule ^(.*)$ http://www.site.pt

# else
RewriteEngine on
RewriteRule ^(.*)$ http://www.site/en/

You have to configure the virtual host to read the .htaccess file.

<directory /var/www/site/>
 Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
</directory>

In your file "httpd.conf" add these lines:

GeoIPEnable On
GeoIPDBFile /usr/local/share/geoip/geoip.dat

Download the file from http://www.maxmind.com/app/geolitecountry and put it in /usr/local/share/geoip/geoip.dat

There are a lot of versions. This one is free for countries :)




Using mod_spdy With Apache2 On Ubuntu 12.04
from: http://www.howtoforge.com/using-mod_spdy-with-apache2-on-ubuntu-12.04

SPDY runs over HTTPS, so we need an HTTPS-enabled web site to test SPDY. Please note that SPDY will fall back to HTTPS if the user's browser does not support SPDY or if things go wrong, so installing mod_spdy doesn't hurt your existing setup.

a2enmod ssl
a2ensite default-ssl
/etc/init.d/apache2 restart

cd /tmp
wget https://dl-ssl.google.com/dl/linux/direct/mod-spdy-beta_current_amd64.deb
dpkg -i mod-spdy-*.deb
apt-get -f install
/etc/init.d/apache2 restart
chrome://net-internals/#spdy

Repair file system error

How to install Eclipse 3.7 on Ubuntu 11.04

The Eclipse packages in Ubuntu are are very out of date. The latest version in the Ubuntu repos is 3.5.2 where as the latest version of Eclipse is 3.7. I’m posting this because Ubuntu 11.04 uses the new Unity desktop which uses overlay-scrollbars (scrolls bars that are hidden until you hover over them). For some reason Eclipse 5.3.2 doesn’t like to play nice with the overlay scrollbars, and I’d rather use the newest version anyways. With Eclipse, you can just download the tar.gz file from eclipse.org and run it no problem, but I like set things up in a cleaner fashion, so here’s how I did it.

1) Download Eclipse. I got eclipse-SDK-3.7-linux-gtk-x86_64.tar.gz

2) Extract it

tar zxvf eclipse-SDK-3.7.2-linux-gtk-x86_64.tar.gz

Or just be lazy and Right Click > Extract Here

3) Move to /opt/ folder

sudo mv -f eclipse /opt/
cd /opt/
sudo chown -R root:root eclipse
sudo chmod -R +r eclipse

4) Create an eclipse executable in your path

sudo touch /usr/bin/eclipse
sudo chmod 755 /usr/bin/eclipse
sudo nano /usr/bin/eclipse

copy this into nano

#!/bin/sh
#export MOZILLA_FIVE_HOME="/usr/lib/mozilla/"
export ECLIPSE_HOME="/opt/eclipse"

$ECLIPSE_HOME/eclipse $*

save the file (^O = Ctrl+o) and exit nano (^X = Ctrl+x)

5) Create a gnome menu item

sudo nano /usr/share/applications/eclipse.desktop

copy this into nano

[Desktop Entry]
Encoding=UTF-8
Name=Eclipse
Comment=Eclipse IDE
Exec=eclipse
Icon=/opt/eclipse/icon.xpm
Terminal=false
Type=Application
Categories=GNOME;Application;Development;
StartupNotify=true

save and exit nano

6) Launch Eclipse for the first time

/opt/eclipse/eclipse -clean &

7) The update Site
http://download.eclipse.org/releases/indigo/

xubuntu brightness

xbacklight -set 100

Create a tar from current directory with command line

tar -cvzf html.tgz *

Git from a SVN

git svn clone -rN  --username username svn://some/repo localreponame

Crie seu branch e mude pra ele:

git checkout -b branchname

Não altere o master branch diretamente, ele deve representar a repositório svn, sempre trabalhe nos branches. Você manda seu trabalho pro master apenas na hora de subir as alterações pro svn.

Com as alterações feitas e commitadas no seu branch, volte para o master e faça o merge:

git checkout master
git merge --squash minhas_paradas

Faça o commit pro git:

git commit -a -m "Funcionalidade tal implementada."

E agora pro svn:

git svn dcommit

E é isso. Pra manter o seu master branch atualizado em relação ao repositório svn use o rebase do git-svn:

git checkout master
git svn rebase

update from a svn

git svn fetch

Remote MySQL Access

GRANT ALL ON *.* TO root@192.168.1.1   IDENTIFIED BY 'palavra-pass'   WITH GRANT OPTION;
FLUSH PRIVILEGES;
We just have to tell Mysql to allow remote logins.
sudo vi /etc/mysql/my.cnf
Out-of-the-box, MySQL only allows connections from the localhost identified by the IP Address of 127.0.0.1.
We need to remove that restriction, so find the line that says
bind-address = 127.0.0.1


netstat -tupan | grep mysql

Recursively delete .svn directories

$ rm -rf 'find . -type d -name .svn'

or

find . -iname ".svn" -print0 | xargs -0 rm -r
