Usage of Linux Commands and UNIX Commands
Here are some usage of the Linux Commands and UNIX Commands, please try to correlate these with Install WordPress on Rackspace Cloud Server guide.
We have changed the directory in this way by using cd (vide the list of Linux commands above) :
cd /var/www/html/
We have downloaded the WordPress (escaping the download from webpage, then uncompress, then upload via ftp) with a single line :
wget http://wordpress.org/latest.tar.gz
Now, it is a tar file (compressed), to make it usable, we need to untar it :
tar xvzf latest
Now give a special attention :
mv /wordpress* .
Can you see the dot ? This is one of the fantastic commands of UNIX. Note the dot “ its moving everything to dot “ your current directory. Give a space between * and dot.
yum -y install httpd php mysql mysql-server php-mysql
Another beauty to UNIX / Linux Commands. Note the -y, you need not to accept the prompts manually. We have installed Apache, MySQL, PHP with just one command line.
