-  * Configure Static IP Address +The commands here will work regardless of the Raspberry Pi hardware (not sure about the compute module) but will work with the Raspberry Pi1/2/3 and Zero.
-===== Configure Static IP Address =====+
 \\  \\ 
-Raspbian Jesse changed the way a static IP Address is configured. The static IP settings are now held in a file located in the //**/etc**// directory called //**dhcpcd.conf**// 
 \\  \\ 
-\\  +[[Configure Static IP Address]]\\  
-To edit the dhcpcd.conf file, enter: +[[Command Line MySQL]]\\  
-\\  +[[UFW - Uncomplicated Firewall]]\\  
-//**sudo /etc/dhcpcd.conf**// +[[Restart Apache2 Web Server]]\\  
-\\  +[[Check Disk Space]]\\  
-\\  +[[Change Password]]\\ 
-At the end of the file add the following lines (with your own IP Address values) +
-\\  +
-\\  +
-//**eth0 +
-\\ static ip_address=192.168.1.14/24 +
-\\ static routers=192.168.1.1 +
-\\ static domain_name_servers=192.168.1.4**// +
-\\  +
-\\  +
-Save and reboot. +
-\\  +
-\\  +
-===== Command Line MySQL ===== +
-\\  +
-Here are a few useful MySQL commands you can run from the command line, handy if you have installed MySQL and you don't have desktop access or a graphical MySQL manager application. +
-\\  +
-\\  +
-Login to MySQL +
-First we must login +
-\\  +
-//**mysql -u root -p**// --- (the //**root**// part assumes //**root**// is your mysql username) +
-\\  +
-\\  +
-Create a MySQL Database +
-\\  +
-//**CREATE DATABASE new_database;**// --- (don't forget the //**semicolon ;**// it's really important) +
-\\  +
-\\  +
-Show a MySQL Database +
-\\  +
-//**SHOW DATABASES;**// +
-\\  +
-\\  +
-\\  +
-===== UFW - Uncomplicated Firewall ===== +
-\\  +
-\\  +
-Uncomplicated Firewall //**UFW**// is a much simpler security solution than using iptables, it is very easy to install and configure. iptables might ultimately have more features, but I think UFW is suitable for most users. +
-\\  +
-\\  +
-To install //**UFW**// from the command line: +
-\\  +
-//**sudo apt-get install ufw**// +
-\\  +
-\\ +
-To allow all ports on the local subnet: +
-\\ +
-//**sudo ufw allow from 192.168.0.0/24**// (allow access from 192.168.0.1 - 192.168.0.254) +
-\\  +
-\\  +
-Allow web port 80 to everyone (internal and external LAN) +
-\\  +
-//**sudo ufw allow 80**// +
-\\  +
-\\  +
-To enable UFW and start rules: +
-\\  +
-//**sudo ufw --force enable**// +
-\\  +
-\\  +
-\\  +
-===== Restart Apache2 Web Server ===== +
-\\  +
-\\  +
-From time to time it might be necessary to restart the Apache Web Server, normally this is required after a configuration change, or if a site has stopped. +
-\\  +
-\\  +
-From the command line: +
-\\  +
-//**sudo /etc/init.d/apache2 restart**// +
-\\  +
-\\  +
-\\  +
-===== Check Disk Space ===== +
-\\  +
-\\  +
-Working from the command line has some disadvantages, one of those is that you don't have a constant graphical reminder of physical and available disk space. To check this we can use the command //**df**// which stands for //**disk filesystem**// +
-\\  +
-\\  +
-From the command line: +
-\\  +
-//**df -h**// --- (the -h means human readable format, so instead values being in bytes, they are displayed at MB or GB etc) +
-\\  +
-\\  +
-$ df -h\\  +
-\\  +
-Filesystem      Size  Used Avail Use% Mounted on\\  +
-/dev/root       6.0G  3.7G  2.0G  66% /\\  +
-devtmpfs        214M     0  214M   0% /dev\\  +
-tmpfs           218M     0  218M   0% /dev/shm\\  +
-tmpfs           218M  4.5M  213M   3% /run\\  +
-tmpfs           5.0M  4.0K  5.0M   1% /run/lock\\  +
-tmpfs           218M     0  218M   0% /sys/fs/cgroup\\  +
-/dev/mmcblk0p6   63M   20M   43M  32% /boot\\  +
-tmpfs            44M     0   44M   0% /run/user/1000\\  +
-\\  +
-\\  +
-\\  +
-===== Change Password ===== +
-\\  +
-\\  +
-To change the password for a user, when logged in as that user, from the command line enter: +
-\\  +
-\\  +
-//** sudo passwd pi **// --- (make sure you use the correct username, pi is just for the example) +
-\\ +
-you will then be prompted to enter, then re-enter the new password +
-\\  +
-\\  +
-//** +
-$ sudo passwd pi\\  +
-Enter new UNIX password:\\  +
-Retype new UNIX password:\\  +
-passwd: password updated successfully +
-**// +
-\\  +
