Cassandra Database(5)Update Version and DataStax

1. Install and Update Version
There is no wget on MAC, so I use this command to get the latest binary file.
>curl -O http://apache.mirror.quintex.com/cassandra/2.0.4/apache-cassandra-2.0.4-bin.tar.gz

Or I can install the wget first.
>curl -O http://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz

>tar -zxvf wget-1.15.tar.gz
>cd wget-1.15
>./configure --with-ssl=openssl
>make
>sudo make install

Verify the installation
>wget —version

Or?
>wget —help

>wget http://apache.mirror.quintex.com/cassandra/2.0.4/apache-cassandra-2.0.4-bin.tar.gz
>tar zxvf apache-cassandra-2.0.4-bin.tar.gz
>mv apache-cassandra-2.0.4 /Users/carl/tool/
>sudo ln -s /Users/carl/tool/apache-cassandra-2.0.4 /opt/cassandra-2.0.4
