- Installation of Dokeos LMS
- Upgrade from a previous version of Dokeos
- Administration section
- Mathematical formulas with LaTeX
Dokeos is mainly a LMS running Apache, MySQL and PHP5 (the so called AMP trilogy).
All these software are open source and freely available.
To run Dokeos LMS on your server, you need to install WAMP, LAMP or MAMP:
- To install WAMP (AMP on Windows), we recommend the XAMPP .exe installer
- To install LAMP (AMP on Linux), use the Package manager of your favourite distribution (Synaptic, RPMFinder etc.). For instance, on a Ubuntu server, use Shell or Synaptic following the Ubuntuguide on Apache and the following sections
- To install MAMP (AMP on Mac OS X), refer to the MAMP dedicated website
MySQL database serverYou will need a login and password allowing to administrate and create at least one database. By default, Dokeos will create a new database for each course created. It means your host should allow you to create and administrate several databases. You can also install Dokeos using only one database, in that case you have to select this option during the installation.
- Download Dokeos LMS
- Unzip it
- Copy the dokeos directory in your Apache web directory. This can be C:\xampp\htdocs\ on a Windows server or /var/www/html/ on a Linux server
- Open your web browser (Internet Explorer, Firefox...) and type http://localhost/dokeos/ if you install locally or http://www.domain.com/dokeos/ if you install remotely
- Follow the web installation process. You can accept all default values. Consider changing the admin password to remember it.
The following directories need to be readable, writeable and executable for everyone:
On Linux, Mac OS X and BSD operating systems you can use the CHMOD 777 command for this (although we recommend you seek advice from an experienced system administrator). In Windows, you may need to check the properties of the folders (by right-clicking on them).
2.5. The following files need to be readable and writeable for the web browser, only during the installation process:
- dokeos/main/inc/conf/configuration.php (if present)
On Linux, Mac OS X and BSD operating systems you can use the CHMOD 666 command for this (although we recommend you seek advice from an experienced system administrator). In Windows, you may need to check the properties of the files and folders (by right-clicking on them).
Do not modify the home_*.html files directly. Instead, choose "Configure the homepage" in the Dokeos administration section.
Windows : with combination packages like XAMPP, out of the box, login and password for MySQL should probably remain empty.
Configuration and security after installation
- Protect your configuration file: make sure no one can overwrite it. You can find the config file in (dokeos folder)/main/inc/conf/configuration.php. Make it read-only (windows/xwindows: right-click the file to edit the properties. linux/bsd/macosx: use the chmod 444 command). The config file is created by Apache so you may need to be root user to change its permissions.
- Protect your installation folder: if the (dokeos folder)/main/install folder is still accessible, someone could install over your existing version (you could lose your data that way). Move the folder somewhere out of the web directories so it is not accessible, change its name, or edit its properties so no one can read or execute it.
- For better security: making the files world-writable will help you install, and solves many issues for people without much admin experience. However, it's better security to make the owner of the apache process (often called apache or www-data) also owner of all the dokeos files and folders. Ths way, these files need only be readable and writable by the Apache process owner, not by the entire world.
- Configure your Dokeos installation: in the administration section of Dokeos, you can use the Dokeos Config Settings to adjust the behavior of your installation.
- Configure Dokeos mail: most of Dokeos uses the mail settings from the php.ini file. However, the announcements tool uses phpMailer (another free software project) and the settings for this tool can be adjusted in (dokeos folder)/main/inc/conf/mail.conf.php.
PHP configurationTo get the best of Dokeos, you need to finetune PHP settings. Consider :
- Editing php.ini file (on windows can be located at C:\xampp\php\php.ini, on Ubuntu Linux : /etc/php5/apache2/php.ini
- search the word "max" and increase values to optimise the server
- you may want to end up with the following values :
max_input_time = 600 ; Maximum amount of time each script may spend parsing request data
memory_limit = 256M ; Maximum amount of memory a script may consume (128MB)
post_max_size = 64M
upload_max_filesize = 100M
Some users could meet problems if their PHP settings don't fit these ones:
- short_open_tag = On
- safe_mode = Off
- magic_quotes_gpc = On
- magic_quotes_runtime = Off
Past Dokeos versions required register_globals to be set to On. This is no longer necessary, this can be set to Off and Dokeos will work fine.
BSD users: these php libraries have to be included during php installation:
- php-mysql The mysql shared extension for php
- php-pcre The pcre shared extension for php
- php-session The session shared extension for php
- php-zlib The zlib shared extension for php
- (optional) php-ldap if you want to be able to use LDAP authentication
3.1 Upgrading from Dokeos 1.8.xIf you upgrade from Dokeos 1.8.x :
- check that you haven't left any customised stylesheet or image*
- download the Dokeos 1.8.6 Svalbard install package from the Dokeos download page
- unzip the new files of Dokeos 1.8.6 over the files of the older version
- point your browser on your portal URL + main/install/
- choose your language and click Upgrade from 1.8.x
* Styles and images are located in the main/css or main/img directories. You can still recover them from your backup if you have made it. Any modified style or image that uses the default style/image name will be overwritten by the next step. To avoid loosing your customisations, always ensure you copy the styles/images under a new name and use and modify the copy, not the original. The original will always be overwritten by newer versions. In Dokeos 1.8.5, we have changed the name of several CSS themes. Backwards compatibility is ensured by the fact that an upgrade only adds the new themes, but you should try and use these new themes rather than sticking to the old ones which will be deprecated shortly (not maintained).
3.2 Upgrading from Dokeos 1.6.xIf you upgrade from a lower version of Dokeos (1.6.x), the first and most important thing to do is to *move* your current directory to another place.
An easy way to do that is to create a subdirectory called "old_version" in your current Dokeos directory and move everything in there using a simple "move" command (i.e. under Linux: mkdir old_version; mv * old_verion/), then make the old_version/ directory writeable by the web server so that courses/ and upload/ directories can be moved from the old to the new installation.
The complete process is as follow:
- move the current Dokeos directory contents to a subdirectory called old_version and make it writeable by the web server. This is important to allow the move of the courses/ and upload/ directories to the new install
- download the Dokeos 1.8.6 install package from the Dokeos download page
- unzip the new files of Dokeos 1.8.6 in the main Dokeos directory. The new directory main should be located directly inside your Dokeos root folder
- point your browser on your portal URL
- choose your language and click Upgrade from 1.6.x and confirm the current directory of the old version
NOTE: The upgrade from 1.6.x to 1.8.x implies a revision of the customised graphics and styles. The new version uses a complete new set of icons and styles, which means the ones from version 1.6 cannot be simply reused. The good news is the version 1.8.x allows you to create your own style in a separate css folder, that you can then reuse through all the 1.8.x versions
Do not delete the previous Dokeos installation directory before installing the new one. When the update is successfully finished, you can remove the old path.
Do not modify the home_*.html files directly. Instead, choose "Configure the homepage" in the Dokeos administration section.
3.3 In both casesThe following directories need to be readable, writeable and executable for the web server:
3.4 Quick-upgrade from 1.6.x guide for LinuxThe following quick-upgrade guide assumes that:
- the Dokeos database username (for MySQL) is "dokeos_db_user" and your login is "dokeos_user"
- the Dokeos installation is currently in /var/www/dokeos/ and it has 777 permissions
- your portal's URL is http://www.portalurl.com/
On the command-line, type:
- cd /tmp
- mysqldump -u dokeos_db_user -p --all-databases --result-file=/home/dokeos_user/dokeos_old.sql
- cp -ra /var/www/dokeos /home/dokeos_user/backup_dokeos
- mkdir /var/www/dokeos/old_version
- mv /var/www/dokeos/* /var/www/dokeos/old_version/
- chmod -R 0777 /var/www/dokeos/old_version/
- wget http://www.dokeos.com/download/dokeos-1.8.6.tar.gz
- tar zxvf dokeos-1.8.6.tar.gz
- sudo cp -ra dokeos-1.8.6/* /var/www/dokeos/
- rm dokeos-1.8.6.tar.gz
- sudo rm -r dokeos-1.8.6/
- Direct your browser to http://www.portalurl.com/main/install/
- Proceed with the installation
- Review the directories permissions
If you have problems, go to the Dokeos website and ask a question on the support forum. Please read the previous messages first to see if there is already an answer to your question. We also maintain a list of Frequently Asked Questions.
To access the Dokeos administration section, open browser, go to your Dokeos adress and log in with the admin user. Then you will see a "Platform admin section" link in the header of the web page. There you can manage users, courses, sessions, portal look and feel, homepage content, course categories etc.
This part is optional, only organisations with an LDAP server will need to read this.
An LDAP module is already provided in Dokeos, but it has to be configured to make it work.
Linux servers: It's possible that you have to recompile php with ldap support. Newer distributions also allow downloading rpms for additional packages.
Activating LDAP in Dokeos
In (dokeos folder)/main/inc/conf/configuration.php, around line 90, you see
//for new login module
//uncomment these to activate ldap
//$extAuthSource['ldap']['login'] = "./main/auth/ldap/login.php";
//$extAuthSource['ldap']['newUser'] = "./main/auth/ldap/newUser.php";
remove the // from the last two lines to activate LDAP.
Ask the LDAP server admin for the settings:
- ldap server name
- ldap server port (usually 389)
- ldap dc
As an example, you should find the following kind of values:
LDAP main server's address: "myldapserver.com"; // your ldap server
LDAP main server's port: 389; // your ldap server's port number
LDAP domain: "dc=xx, dc=yy, dc=zz"; //domain
By default, Dokeos will check if the "employeenumber" field has a value. If it has, then Dokeos will
consider this user as being a teacher.
If you want to change this behaviour, you can edit main/auth/ldap/authldap.php, function ldap_put_user_info_locally(), and change the if (empty($info_array[$tutor_field])) condition to whatever suits you.
You can also remove this check by removing the condition and leaving only the $status = STUDENT; line.
Protected LDAP servers
Some LDAP servers do not support anonymous use of the directory services.
In this case, you should fill in the appropriate fields in the administration panel (e.g. "manager" and "mypassword") and Dokeos will try to authenticate using these, or fall back to anonymous mode before giving up.
LDAP import into sessions
There is a new set of scripts now that allow you to insert users
from LDAP directly into a Dokeos session. This, however, relies on a
set of static choices in the LDAP contact attributes.
The fields used intensively by the Dokeos module are:
- uid, which is matched to the username in Dokeos
- userPassword, which is matched to the user password, although this part will only work for non-encrypted passwords for now, but it shouldn't be necessary if using the LDAP server as authentication
- ou should end with the year of the person registration or any criteria you will use to filter users, so that they can be retrieved on that criteria
- sn is used as the lastname field in Dokeos
- givenName is used as the firstname field in Dokeos
- mail is used as the email field in Dokeos
You can enable mathematical equations writing inside the Dokeos online editor (FCKEditor) by applying the following steps:
- 1. Configure your Apache installation to add a cgi-bin directory that contains a symbolic link to the mimetex.cgi in dokeos/main/inc/lib/mimetex/(*see below)
- 2. Reload your Apache configuration
- 3. Edit the dokeos/main/inc/lib/fckeditor/myconfig.js and
- 3.1. Add FCKConfig.Plugins.Add("mimetex", "en", sOtherPluginPath ) ; at the end of the file
- 3.2. Add 'mimetex' at the end of the
FCKConfig.ToolbarSets lines where you want the LaTeX icon to appear
(there is one FCKConfig.ToolbarSets by tool). For example:
FCKConfig.ToolbarSets["Test"] = [You can add it to all the tools, or only to the document and tests tools, for example
- 4. For Windows servers only, update dokeos/main/inc/lib/fckeditor/editor/plugins/mimetex/mimetex.html to replace mimetex.cgi by mimetex.exe
- 5. Clear your browser's cache to test it (very important). This can be done using your browser's settings page
