Open eClass 2.9
The new version of Open eClass retains backward compatibility (with previous versions). For that reason, you can upgrade an already installed platform from prior versions to the current 2.6 easily and quickly, following the upgrade instructions provided below. Keeping a safety record of the course contents and the database before beginning to upgrade is recommended.
Current version of Open eClass DOESN'T include database administration tool phpMyAdmin. If you wish, you can copy folder (path του eclass)/modules/admin/mysql/ in a temporary folder (e.g. /tmp). After upgrade has completed you can restore it to its previous location. Otherwise you can download latest version from here.
(e.g. Solaris, Redhat, CentOS, Debian, Suse, Ubuntu etc)
All operations presuppose you have the administrator's rights (root) on your computer. The following example presumes that the eClass platform is already installed on directory /var/www/html.
Due to some changes introduced by the new version (2.9) you will have to delete the old and install the new one. To make sure that you old configuration remain intact you must do the following actions:
Current version of Open eClass DOESN'T include database administration tool phpMyAdmin. If you wish, you can copy folder (path του eclass)/modules/admin/mysql/ in a temporary folder (e.g. /tmp). After upgrade has completed you can restore it to its previous location. Otherwise you can download latest version from here.
We consider that you have downloaded openeclass-2.9.tar.gz on the /tmp directory.
Go to the directory you have installed in eClass. e.g.
cd /var/www/html
Move the configuration file (eclass/config/config.php) in another temporary directory (e.g. to directory /tmp)
mv /var/www/html/eclass/config/config.php /tmp
Delete all the directories except courses and config e.g.
cd /var/www/html/eclass/ rm -rf images/ include/ info/ install/ manuals/ template/ modules/
Unzip and untar openeclass-2.9.tar.gz in a temporary directory (/tmp) e.g.
tar xzvf /tmp/openeclass-2.9.tar.gz
Then copy from the temporary directory /tmp/openeclass-2.9 all of its contents in the installation directory e.g.
cp -a /tmp/openeclass-2.9/* /var/www/html/eclass/
So with the above steps you have replaced directory eclass, with the new one. Then move file config.php to directory config. e.g.
mv /tmp/config.php /var/www/html/eclass/config/
Correct (if necessary) the files and sub-directories permissions: (supposing that the apache is running as user www-data)
cd /opt/eclass
chown -R www-data *
find ./ -type f -exec chmod 664 {} \;
find ./ -type d -exec chmod 775 {} \;
Having completed the previous steps, you will have installed the new eClass version (eClass 2.9) files successfully. Then, move on to the second step in order to upgrade the platform databases.
(Windows2000, WindowsXP, Windows2003, Windows Vista, Windows 7, Windows2008)
The following example presupposes that eClass has already been installed to directory C:\Program Files\Apache\htdocs\ and that you have downloaded openeclass-2.9.zip.
Current version of Open eClass DOESN'T include database administration tool phpMyAdmin. If you wish, you can copy folder (path του eclass)/modules/admin/mysql/ in a temporary folder (e.g. /tmp). After upgrade has completed you can restore it to its previous location. Otherwise you can download latest version from here.
For safety and security reasons, access to phpMyAdmin should be done through the browser's cookies. If you want to change it, you can refer to the config.inc.php file of phpMyAdmin.
Due to several changes included by the new version (2.9) you will have to delete the old and install the new one. To make sure that you old configuration remain intact you must do the following actions:
As soon as the above have been completed, you will have installed the new eClass version files (eClass 2.9) successfully. Then, follow the second step so as to upgrade the platform database.
For Unix/Linux systems only: The process of platform database upgrade includes changes to config.php. As a result, you will temporarily need to change your access rights on the config.php file and the /config directory to read-write (chmod 664).
Enter the following URL on your browser:
http://(url of eclass)/upgrade/
You will be prompted for the username and password of the platform administrator. After providing them, you will be asked to change/correct contact details, as well as students' registration mode on the platform (free or applied registration). The database upgrade will begin afterwards. You will see several messages concerning your working progress. Probably you will not see any false messages. Note that depending on the number and content of courses, it is possible that the process will last for a long time.
In the opposite case (namely if error messages occur), then it is possible for a course not to be operating properly. Such error messages may occur if you have altered the structure of an eclass database table. Note (if possible) the accurate error message you saw.
If you face any problems with any course after the upgrade, contact us (mailto:info@openeclass.org).
In order to make sure that the platform has been upgraded, login as administrator and click to “Admin tools”. Among other things, version 2.6 has to be indicated. You can alternatively click on the “Platform Identity” link on the homepage. Version 2.6 of the platform will be indicated.
You are ready! The upgrade process has been completed successfully.
If you want to see the new features of the new version, go to CHANGES.txt text file. Read forward for further additional configuration options.
If you want to modify any message of platform then proceed with the following actions: Create a file of type .php with name english.inc.php (or greek.inc.php) and place it in directory (eclass path)/config/. Find the varible name which contains the message you wish to change and assing it the new message. e.g. If you want to change message $langAboutText = “The platform version is”; create the file english.inc.php in the directory (eclass path)/config/ with the following contents:
<?php $langAboutText = "Version is";
This way, you will preserve custom messages in future upgrades of the platform.
You can modify the names of the basic roles of the users of the platform by redefining in these files the message variables found in (eClass_path)/modules/lang/greek/common.inc.php.
You can add text (e.g. information, links, etc.) to the left and right sidebars of the platform homepage by assigning the variables $langExtrasLeft and $langExtrasRight respectively.
Open eClass supports mathematical symbols in the Exercises, Forums and Announcements subsystems. In Exercises you can add math symbols in the “Exercise Description” field when creating or modyfying a new exercise, and in “Comment” when adding or modifying a question, in Forums when you compose a new message or reply to an existing one, and in Announcements when a new announcement is created. Math symbols must be enclosed in [m] and [/m] tags. E.g. when you type
[m]sqrt{x-1}[/m]
the square root of x-1 will appear. Mathematical symbols syntax can be found in the PhpMathPublisher help file. Older versions used the <m> and </m> which are still supported, although using the newer tags in brackets is recommended.
To use the platform with a web server with SSL support (e.g. https://eclass.gunet.gr), you define the urlSecure variable in config.php. For example: $urlSecure = “https://eclass.gunet.gr”
If you have SSL support activated and you want to enforce it between the platform and native mobile clients for increased security, you can do it by defining the urlMobile variable on config.php. e.g.$urlMobile = “https://eclass.gunet.gr”
The default theme of platform is 'classic'. You can change it later from the admin tool to 'modern'. Note the change will be visible to users after next login to platform.
You can configure several options of platform. After logging as admin user, click in “Admin Tools” and after that, click in “Configuration File”. Among other, you can change the available languages (e.g. greek, italian) etc.
By default platform supports uploading of all the usual text, audio, video and image file types. If you desire to add a new file type, type its extension in 'Teacher while list' or 'Student while list' textarea correspondingly.
