Setting Up Apache with PHP

2017-08-28T14:56:54Z

Bun:

== Installing Apache + PHP ==
Add the main packages with the command:

{{Cmd|apk add apache2 php5-apache2}}

The <code>php5-apache2</code> package can be found in the
[[Enable Community Repository|community repository]],
which you may have to add to <code>/etc/apk/repositories</code>.

== Testing ==

Move to the directory where your site will reside:

{{Cmd|cd /var/www/localhost/htdocs}}

And create an index.php file to test if everything is ok:

{{Cmd|vi index.php}}

Add the following lines in the file:

<pre>
<?php
phpinfo();
?>
</pre>

That done, let us start apache2 web server:

{{Cmd|rc-service apache2 start}}

Now access: http://<ip_address> and if everything is ok you will see the PHP info page.

== Ending ==

Finally let us set up apache2 to start on operating system startup:

{{Cmd|rc-update add apache2}}

Now you can create your PHP site and host in this directory.

== Note ==
This is the easiest way to setup Apache with PHP support, but it's the most inefficient (resource wise) setup, please refer to [[Apache with php-fpm]]

Bootloaders

Bun:

By default Alpine uses Syslinux as bootloader.
This page shows the basic steps you need to perform, if you for any reason want to switch bootloaders or apply some manual configuration.

= Installing Syslinux =

If you want to switch from another bootloader back to Syslinux, or if you for some reason want to install Syslinux manually, the following steps are required.

Install the <code>syslinux</code> package:

<pre>apk add syslinux</pre>

If you're using GPT partitions, install the GPT MBR onto the drive you want to install the bootloader on (in this case <code>/dev/sda</code>):

<pre>dd bs=440 count=1 conv=notrunc if=/usr/share/syslinux/gptmbr.bin of=/dev/sda</pre>

Or if you're using DOS partitions, install the DOS MBR instead:

<pre>dd bs=440 count=1 conv=notrunc if=/usr/share/syslinux/mbr.bin of=/dev/sda</pre>



Next install the required Syslinux binaries. Despite being called <code>extlinux</code>, Syslinux supports booting from FAT12/16/32, NTFS, ext2/3/4, Btrfs, XFS, and UFS/FFS filesystems.

<pre>extlinux --install /boot</pre>

The configuration file is located in <code>/boot/extlinux.conf</code>.
Alpine ships with a script called <code>update-extlinux</code> which automatically (re)generates this file, for example on updates to Syslinux.
The settings for this script can be found in <code>/etc/update-extlinux.conf</code>, including the option to disable automatic overwriting of <code>/boot/extlinux.conf</code>.
You can also place additional menu entries in the <code>/etc/update-extlinux.d/</code> directory, e.g. for dual boating.

== EFI ==

{{Todo|Work in progress. This should at least get you started.}}

Assuming <code>/mnt</code> is a FAT32 partition of type EF00 and <code>/boot</code> belongs to the rootfs created after running <code>setup-disk</code>:

<pre>
mkdir -p /mnt/EFI/syslinux
cp /usr/share/syslinux/efi64/* /mnt/EFI/syslinux/
cp /boot/extlinux.conf /mnt/EFI/syslinux/syslinux.cfg
cp /boot/vmlinuz* /mnt/
cp /boot/initramfs* /mnt/
</pre>

You may need to modify <code>/mnt/EFI/syslinux/syslinux.cfg</code> to change the paths to absolute paths (just add a / in front of the vmlinuz/initramfs entries),
or copy the files to <code>/mnt/EFI/syslinux</code> instead (XXX: untested).

= Installing GRUB =

To install GRUB in BIOS mode, (optionally) remove the Syslinux package and install the required GRUB packages:

<pre>apk del syslinux
apk add grub grub-bios</pre>

Next install the MBR and GRUB binaries to disk:

<pre>grub-install /dev/vda</pre>

GRUB ships with an automatic config generator, including some automatic detection of other operating systems installed on the device:

<pre>grub-mkconfig -o /boot/grub/grub.cfg</pre>

This script can be configured via the <code>/etc/default/grub</code> file.
See [https://www.gnu.org/software/grub/manual/html_node/Simple-configuration.html] for a list of available options.
