Instalare - LimeSurvey CE
From LimeSurvey Manual
General
Proiectul LimeSurvey oferă două moduri de a instala LimeSurvey:
- Pe serverul dvs. web:
În acest caz, trebuie doar să urmați instrucțiunile de pe această pagină începând cu pasul 1.
- Pe computerul local Windows:
De obicei, doriți să instalați LimeSurvey pe computerul dvs. local numai dacă doriți să creați sondaje la nivel local (în principal din motive de viteză sau dezvoltare/test) și să le încărcați mai târziu în instalarea dvs. live LimeSurvey pe un server web. În acest scop, am pregătit un pachet special LimeSurvey care include serverul web, baza de date, aplicația LimeSurvey și instrucțiuni de instalare.

- SimpleXML
- etc...
Extensii opționale PHP:
- GD-Library cu suport FreeType instalat este necesară pentru captchas, diagrame frumoase în statistici sau pentru a încărca imagini prin editorul HTML - vezi [https:/ /php.net/manual/image.setup.php Documentația PHP GD-Library Extension]
- „IMAP' (destul de standard) este necesar pentru [[Email bounce tracking system|email bounce tracking system] ] - consultați documentația PHP IMAP Extension
- Este nevoie de „LDAP” instalat pentru a importa participanții la sondaj folosind LDAP - consultați [https:/ /php.net/manual/en/book.ldap.php Documentația PHP LDAP]
- „Zip' (destul de standard) este necesar pentru încărcarea șablonului, importul de resurse arhivate .zip și exportul excel - vezi documentația PHP Zip Extension
- „Zlib' (destul de standard) este necesar pentru ComfortUpdate - vezi [https ://php.net/manual/zlib.setup.php Documentația PHP Zlib Extension]
În cele mai multe cazuri, furnizorul dvs. de server web sau administratorul de sistem vă va putea ajuta cu aceste componente opționale.
Dacă doriți să rulați serverul Microsoft IIS, ar putea fi de asemenea de ajutor să aruncați o privire la Instalarea pe XP cu IIS.
Browser compatibility
For the survey-taking side, we currently support IE11 (intranet-mode excluded) and all newer comparable browsers like Edge, FF, Chrome, Opera etc. with activated JavaScript.
For the administration part, we currently support Edge and all newer comparable browsers like FF, Chrome, Opera etc. with activated JavaScript. We do not support any Internet Explorer versions in the administration part anymore.
Screen sizes
We support any reasonable screen size for survey taking (360px x 640px and up). The minimum supported screen resolution for the LimeSurvey administration page is 1280px x 1024px.
Hosting for LimeSurvey
LimeSurvey should work with most hosting companies that provide PHP and MySQL. If you want a ready-installed version of LimeSurvey, you could try LimeSurvey Cloud, else check out our list of LimeSurvey-compatible hosting companies.
Download the LimeSurvey package
Download the latest stable LimeSurvey zip package (there are also gzip, bz2 and 7zip packages available for your convenience) and save it to your local disk.
Unpack the LimeSurvey package
Uncompress the zip file into a dedicated directory/folder using your preferred compression software. When you uncompress the file make sure that you uncompress the directory structure with the files (this is default behavior for most compression programs). The path name for the installation directory should not include '(' or ')' special characters, but it may include the space character.
Collect information about your server
You will need to know the following things to install LimeSurvey on your web server correctly:
- Your intended website URL where your scripts will reside (e.g. http://my.domain.com/limesurvey).
- The physical disk location on your server where your scripts will reside (e.g. /home/usr/htdocs/limesurvey).
- The IP/net location of your database server (i.e. localhost).
- If your database server uses a non-standard port, find out which port it is.
- Your user name and password for your database server.
- With most providers you can't let the script create the database, but have to do it yourself. If you are using such a provider, please create a database (for example limesurvey) yourself.
Upload the files to your web server
Using your FTP program (e.g. FileZilla), connect to your web server and create a directory to store your scripts. Then upload the files using the directory structure they are in. Make sure you upload the files in binary mode (check the settings of your FTP program). Please note that uploading in ASCII mode can lead to uncommon errors (e.g. 'class not found' error during installation), also images may not be uploaded correctly.
Set directory permissions
For the script to work properly it needs certain access to some directories - this applies especially to Linux/*nix systems.
- The "/limesurvey/tmp" directory (and all its subdirectories and files) are used for imports & uploads and should be set to Read & Write for your webserver.
- The "/limesurvey/upload/" directory (and all its subdirectories and files) must also have Read & Write for your webserver in order to enable picture and media files upload.
- The "/limesurvey/application/config/" directory also needs Read & Write permissions for your webserver.
- The other directories can be set to Read Only. You may wish in Linux/Unix to set the permissions on each file within the /limesurvey/admin directory to Read Only.
If you are using Linux, then setting permissions depends on your webserver configuration. For example, if you use Apache HTTPD on CentOS, type chmod -R 755 <directory> ; chown -R apache <directory>. This will give everyone access to read, and your webserver will have the permission to write. Check the following link for more information on Linux permissions.
Create a database user
LimeSurvey will create a database and the tables inside it. To be able to do this, it will need the user name and password of a database user. We generally recommend creating a database user with the following permissions:
- MySQL: SELECT, CREATE, INSERT, UPDATE, DELETE, ALTER, DROP, INDEX
- PostgreSQL: SELECT, INSERT, UPDATE, DELETE, TRUNCATE, TRIGGER
- Microsoft SQL Server: Unknown - if you can find out this information, please complete it.
Run the installation script
Go to "example.org/limesurvey/admin". If you configured everything correctly, the LimeSurvey installer should be starting - just follow the instructions. You will be asked whether you wish to create the database and/or create the tables inside the database. LimeSurvey will then create the needed tables in the database.
Connect to the administration script for the first time
You are done when the installation finishes! Open your browser and enter the URL to the LimeSurvey administration. Assuming you used 'limesurvey' as the directory name to store the files in, this will be something like "http://www.example.com/limesurvey/admin".
You should get a login screen. The default login credentials (if they have not been changed during the installation) are:
User: admin
Password: password
You will be prompted to change the default password after you logged in. Have fun!
Further configuration
Caching
LimeSurvey uses the Yii file cache by default, but it can be configured to use other cache engines. Possible other caches are:
- Memcached
- Redis
- WinCache
- XCache
Please see the Yii documentation for full description.
Since LimeSurvey 4.0.0 you also have the possibility to cache calculations in the ExpressionScript. This can provide a significant speed-up depending on survey complexity. To enable the emcache, add this in your config.php file (components array):
'emcache' => array('class' => 'CFileCache'),
As with the main Yii cache, other cache systems can be used.
The emcache is not compatible with randomized surveys, and will be automatically turned off in such cases.What if I have problems...
Like all computer programs, most of the time things will work just like the instructions say, but sometimes they just won't. There are too many possible reasons for things not going according to plan to describe here. If you have trouble, first check out the Installation FAQ. If you don't find your answer there, please post your problem and any error messages in the LimeSurvey forums, open a support ticket (only for customers using LimeSurvey Cloud), or join our Discord channel.
