SSH ("Secure SHell") is a means of establishing a secure command-line shell interface on a remote system.
On Unix / Linux you can open a secure shell with the command ssh -l <username> <host> where <username> should be replaced with your actual username and <host> by the domain name or IP address of the host to which you want to connect.
On Microsoft Windows you can use the PuTTY terminal emulator.
You will be prompted for the password associated with the username. If this is the first time you have attempted to connect to this host using SSH you will be asked to confirm the fingerprint of the host you are attempting to connect to. To exit an SSH session, type Control-D or "exit". For example, to connect to host www.mydomain.com using username "goliath" you would enter:
ssh -l goliath www.mydomain.com
Joomla Release Packages come in two varieties:
Full Release Packages are much larger than Patches, but are easier and less error prone for novice users to install. In order to use a Patch Package, you must find the correct upgrade from your current Joomla Version to the latest release of Joomla that you intend to install. E.g., if you are currently running Joomla-1.5.7 and want to upgrade to Joomla-1.5.15, then you must download this package file:
Both upgrade and full release packages are meant to be unpacked in the top-level directory of your Joomla web site distribution. Before unpacking the package, change directory to the top level of your http site. For example, if your top level Joomla files are located in /var/www/htdocs, use the following Unix command to change to that directory first.
You can then extract new version files over your old joomla files:
tar xjvf Joomla_1.5.15-Stable-Full_Package.tar.bz2
Below are some examples of using mysql from the Unix command line. If you do not understand what these commands are used for, please be careful! You may want to read the mysql documentation at http://www.mysql.org/ before proceeding.
Some sample MYSQL commands from the command line:
# upgrade sql via MYSQL for RC1 to RC2
mysql -utodd -Djoomladbname -p < diff_rc1_to_rc2.sql
# no changes from rc2 to rc3
# upgrade from rc3 to rc4
mysql -utodd -Djoomladbname -p < diff_rc3_to_rc4.sql
# no changes from rc4 to live release
If you have downloaded one of the other zipped types from Joomla, check out http://www.accessdataservices.com/blog/unix-101-unzipping-files/ for different ways to unzip different types of files. Note that the Unix tar command can unzip and unpack most file types in a single step. Also note that .zip files are not recommended for use on Unix (or Linux) systems, because they lose much information about file ownership and permissions.
