+ | Install those first. Compiling ikiwiki takes a while on a Raspberry Pi. Be patient. | ||
+ | |||
+ | If you want to have images handle by the wiki, you will need also Imagemagick | ||
+ | |||
+ | Although ikiwiki could be running from any server, I found it easier to run it behind Apache. So be sure to have that installed. | ||
+ | |||
+ | Create an unprivileged user (here called wiki) who will be editing the wiki: | ||
+ | < | ||
+ | sudo useradd -m wiki | ||
+ | sudo passwd wiki | ||

+ | Device | ||
+ | / | ||

+ | </ | ||
+ | |||
+ | * Take note of the start number for partition 2 (if that's the one you want to resize) | ||
+ | * Type '' | ||
+ | * Type '' | ||
+ | * This new partition needs to be a primary partition so type '' | ||
+ | * Next enter '' | ||
+ | * You will now be prompted for the first sector for the new partition. Enter the start number from the partition 2 you deleted before. | ||
+ | * Next you will be prompted for the last sector you can just hit enter to accept the default which will utilize the remaining disk space. | ||
+ | * Type '' | ||
+ | * Reboot the Pi: '' | ||
+ | * Once the system has reboot and you are back at the commandline enter: '' | ||
+ | * Reboot one more time. | ||
+ | * You can now verify that the system is using the full capacity of the SD Card by entering the following command: '' | ||
+ | |||
+ | === Why This Works === | ||
+ | Actually, when we delete a partition, we don't delete data, we just delete the reference to the partition in the partition table. By creating a new partition exactly from the same spot and of the same type, we keep the data but expanded the size to the full available space of the SD card. | ||
+ | |||
+ | By resizing (which is safe to run on a mounted disk), we tell the file system to use all the space in the new partition. | ||
+ | ===== Python UnicodeEncodeError horror ===== | ||
+ | So your Python script works on your machine. But when you port it to a freshly installed Arch Linux Arm on a Pi, all hell breaks loose as soon as a weird character pops up. Something like this shows up: | ||
+ | < | ||
+ | Well, don't start modifying your Python code (as you said, it does not have that problem on your machine). | ||
