Do you have to remember an ever increasing amount of passwords? If you do, then KeePassX might be of interest to you. It’s a password manager which has high security standards and which is additionally available on Microsoft Windows and Mac OS X. If you are running Ubuntu (this probably also applies to recent Debian versions), the following snippet might be of interest to you as it shows how to install version 0.4.3 of this program. After installation, you can find it in your desktop manager’s application menu (under GNOME 2 it’s located in Applications -> Accessories -> KeePassX).

NAME='keepassx-0.4.3'
FILENAME=$NAME'.tar.gz'

echo ':: Installing prerequisites...'
sudo apt-get install libxtst-dev libqt4-dev qt4-qmake

echo ':: Downloading and extracting file...'
wget 'http://downloads.sourceforge.net/keepassx/'$FILENAME
tar xvf $FILENAME

echo ':: Installing...'
cd $NAME
qmake
make
sudo make install

echo ':: Cleaning up...'
cd ..
rm -rf $NAME $FILENAME

How-to install nginx

Since there is so much buzz around nginx, I wanted to give it a try on my small home server. The server is running a desktop edition of Ubuntu 10.04 (I keep it as backup machine in case my laptop breaks), so keep this in mind. The following bash script will download nginx version 1.1.12, its dependencies and install it. Also, a user nginx will be created.

# Start by creating an appropriate user
useradd -r nginx
mkdir /home/nginx
chown nginx:nginx /home/nginx/

# Retrieve nginx dependencies
cd /home/nginx
mkdir library
cd library
wget http://zlib.net/zlib-1.2.5.tar.gz
tar xfz zlib-1.2.5.tar.gz
rm zlib-1.2.5.tar.gz
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.21.tar.gz
tar xfz pcre-8.21.tar.gz
rm pcre-8.21.tar.gz
cd ..

# Installing nginx
wget http://nginx.org/download/nginx-1.1.12.tar.gz
tar xfz nginx-1.1.12.tar.gz
rm nginx-1.1.12.tar.gz
cd nginx-1.1.12
./configure --prefix=/home/nginx \
    --user=nginx \
    --group=nginx \
    --with-pcre=../library/pcre-8.21/ \
    --with-zlib=../library/zlib-1.2.5/
make
make install
cd ..
rm -rf nginx-1.1.12/
chown -R nginx:nginx *
sed -i 's/listen\s*80;/listen 8080;/g' conf/nginx.conf
export NGINX_HOME='/home/nginx/'
export NGINX_PID_FILE=$NGINX_HOME'logs/nginx.pid'

In case you encounter any problems, please refer to the short, but sufficient, official documentation. If it worked out for you, you can now use the following commands to start and stop the server as well as to reload the config.

# Start nginx (runs on port 8080)
su nginx -c $NGINX_HOME'sbin/nginx'

# Reload nginx config
kill -HUP $(cat $NGINX_PID_FILE)

# Stop nginx
kill -QUIT $(cat $NGINX_PID_FILE)
