Hint: I'm installed OwnCloud on an TP-Link TL-WR2543ND, using lighttpd and sorry, it's dead slow!

Use current trunk-version of OpenWrt[0], cause one necessary package (php5-mod-zip) isn't available in latest stable version 10.3.1. The web resources of OpenWrt will help you figuring out what firmware you will need for your device and how to flash it.

ownCloud is around 30 MB and you will like to store your data somewhere. So best both is done on some external storage cause small routers don't have that much. Have a look in the OpenWrt-Wiki at usb.essentials [1] and usb.storage[2], and figure out what USB-mode your device is using (ohci or uhci) and know what filesystem is on your storage (here: ext4).

You have to run an update of the package-lists before you can install any software

opkg update

Install USB-support (this is for USB 2.0, see usb.essentials for USB 1.1 support)

opkg install kmod-usb2
insmod ehci-hcd

If you see messages like "unresolved symbol usb_calc_bus_time" try loading usbcore and then try ehci-hcd again:

insmod usbcore
insmod ehci-hcd

Install USB-storage support

opkg install kmod-usb-storage kmod-usb-storage-extras block-mount kmod-fs-ext4 kmod-scsi-generic

Create a mount-point like this

mkdir /mnt/sda1

Figure out which device is your USB-stick/drive and mount it. It helps to list /dev with the USB-device and without - in this case its /dev/sda1.

mount -t ext4 /dev/sda1 /mnt/sda1 -o rw,sync

Get fstab to auto-mount the usb-stick on startup, otherwise your webserver won't come up and you have to start it after mounting manually. ( Insert how-to here) Even if auto-mounting on startup works, it probably ends too late when the webserver tries to start. To make sure the webserver is up after booting, insert this line into /etc/rc.local before "exit 0":

/etc/init.d/lighttpd start

If your device has only 8 MB of flash-memory, it is to small to get all the dependencies on it. You'll need to put the operating-system on the USB-device as well. Have a look at extroot and follow the instructions for trunk. The flavour "New external overlay variant (pivot overlay)" worked for me on a TP-Link WR1043ND quite well. Remember to use both steps while "Duplicate Data": pivot overlay and pivot root.

May you have allready the OpenWrt web-interface (luci) on your router, may you want to get the OpenWrt web-interface initially.

If you like OpenWrt-webinterface luci, install it

opkg install uhttpd luci

You're able to start uhttpd twice: Add an new uhttpd section in the /etc/config/uhttpd file. And don't forget to serve luci on another port.

after a restart of uhhtp

/etc/init.d/uhttpd restart

you should be able to reach luci under e.g. http://192.168.1.1:81

Somewhere I got the hint to use lighttpd for running ownCloud. I tried out uhttpd simultaniously - the interfaced looked quite broken.

And may you would no run two web server simultanious.

Disable uhttpd even after reboot

/etc/init.d/uhttpd disable
/etc/init.d/uhttpd stop

Remember, at this point you can't use luci. So install lighttpd:

opkg install lighttpd lighttpd-mod-cgi lighttpd-mod-fastcgi lighttpd-mod-access

If the httpd server is located on the SquashFS it is not recomend to remove the files from the space, due to wasing space by doing this (learn more about SquashFS!). Otherwise you're able to remove httpd by typing

opkg --force-depends remove uhttpd

Edit the config-file /etc/lighttpd/lighttpd.conf

First configuration lighttpd, and you are able to use luci again. uncomment the mod_cgi:

server.modules = (
        "mod_cgi"
)

see errors on syslog:

server.error-log-use-syslog = "enable"

assign luci to lua

cgi.assign = ( "luci" => "/usr/bin/lua" )

At this point it's possible to start the server…

/etc/init.d/lighttpd start
/etc/init.d/lighttpd enable

…and access luci again. Use e.g. http://192.168.1.1:81

server.modules = (
	"mod_access",
	"mod_cgi"
)

cause, we'll move the Luci-Server to the Port 81; we need the port 80 for the OwnCloud-Server:

server.port = 80

Set www-root for OwnCloud (We will add a new Server for Luci later.):

server.document-root = "/www/owncloud"

Add these lines to secure the access to the data according to ownCloud WebServer-notes[3], beware that in this example the ownCloud-folder is our www-root

$HTTP["url"] =~ "^/data/" {
	url.access-deny = ("")
}  

$HTTP["url"] =~ "^($|/)" {
	dir-listing.activate = "disable"
}

And append a new server for luci:

$SERVER["socket"] == ":81" {
	server.document-root = "/www"
	cgi.assign = ("luci" => "/usr/bin/lua")
}

Due to this remember to remove the line, we're added bevore:

#cgi.assign = ( "luci" => "/usr/bin/lua" )

ReStart the webserver with

/etc/init.d/lighttpd restart

And make sure it's enabled for next boots:

/etc/init.d/lighttpd enabled

Get the dirty part: php and sqlite. I am not sure if really all these packages are necessary, but it seems so:

opkg install php5 php5-cgi php5-fastcgi php5-mod-json php5-mod-session php5-mod-zip libsqlite3 zoneinfo-core php5-mod-pdo php5-mod-pdo-sqlite php5-mod-ctype php5-mod-mbstring php5-mod-gd sqlite3-cli php5-mod-sqlite3 php5-mod-curl curl php5-mod-xml php5-mod-simplexml php5-mod-hash php5-mod-dom php5-mod-iconv

Configure /etc/php.ini to our needs, mainly uncomment the installed Dynamic Extensions and change the doc_root to our www-root:

;open_basedir=

error_log = syslog

doc_root =
cgi.fix_pathinfo=1

extension=ctype.so
extension=curl.so
extension=dom.so
extension=gd.so
extension=hash.so
extension=iconv.so
extension=json.so
extension=pdo.so
extension=pdo_sqlite.so
extension=session.so
extension=sqlite3.so
extension=xml.so

memory_limit = 32M

Play around with memory_limit, I reduced the value form 8MB to 4MB … but maybe 50MB might be better with 64MB RAM.

run php

/etc/init.d/php5-fastcgi enable
/etc/init.d/php5-fastcgi start

Uncomment to enable the fastcgi module

server.modules = (
	"mod_access",
	"mod_fastcgi",
	"mod_cgi"
)

Add "index.php" to the List of index-file.names:

index-file.names = ( "index.php", "index.html", "default.html", "index.htm", "default.htm" )

static-file.exclude-extensions = (".php, ".pl", ".fcgi")

include php by using fast-cgi (gample against max-procs for performance):

fastcgi.server = (
	".php" => ((
		"bin-path" => "/usr/bin/php-cgi",
		"socket" => "/tmp/php.socket",
		"max-procs" => 1
	))
)

Only if your using normal cgi mode for PHP, your need the following line

cgi.assign = (".php" => "/usr/bin/php-cgi")

ReStart the webserver with

/etc/init.d/lighttpd restart

Now point your browser to http://yourhost/index.php (first create a helpful content to this file) and see if this manual missed something. If so; please contact the author (see details below) or get an account for this wiki and fix the how-to yourself

Probably you want to run lighttpd with SSL/https to get your traffic crypted. These instructions are taken from [4]. For generating a key you need to install libopenssl and the openssl-utils

opkg install libopenssl openssl-utils

Now you can create a folder for your key like this

mkdir /etc/lighttpd/ssl/YOURDOMAIN -p

Within that you can create your key with the following command. You will be asked to provide some information for the certificate.

openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes

Make the file only accessable to root

chmod 0600 /etc/lighttpd/ssl/YOURDOMAIN

Now we can uncomment the lines for SSL in lighttp.conf and modify the path to the server.pem:

ssl.engine = "enable"                             
ssl.pemfile = "/etc/lighttpd/ssl/YOURDOMAIN/server.pem"

Restart the webserver afterwards - don't wonder if it isn't anymore reachable via http:

/etc/init.d/lighttpd restart

download and unpack the newest revision:

Now you should cleanup:

You have to configure the rights of the /www/owncloud in addition.

Open your Website http://192.168.1.1/ and configure your first steps then wait for a loooonnnnngggg time and you'll see the result

Format your USB drive as ext3 or ext4 and plug it into your Openwrt router

download the script from gizfun.com, run it and you are good to go

wget http://www.gizfun.com/dl/web_for_openwrt.sh

sh web_for_openwrt.sh

the script will download, install and configure all necessary web server components automatically. All software are installed onto the external USB storage.

• Even php5-mod-xml (and php5-mod-simplexml, -xmlreader and -xmlwriter) are installed, ownCloud lists php-xml as a missing dependency. Anyone an idea?
• It can be fix if select php5-mod-xml when you make php5. If you not, libxml will not be loaded, even phh5-mod-xml is installed later.
