General

The LimeSurvey project offers two ways of installating LimeSurvey:

• On your webserver:

+In that case just follow the instructions on this page starting with step 1.

• On your local Windows PC:

+You usually only want to install LimeSurvey on your local PC if you want to create surveys locally (mainly for speed or test reasons) and upload them later to your live LimeSurvey installation on a web server. For this we have prepared a special package for LimeSurvey which includes the web server, the database and the LimeSurvey application and instructions how to install it.

1. 确定 LimeSurvey 能够在你的网站使用

确定服务器符合以下要求:

必须:

• 约 40 兆的磁盘空间保存脚本
• MySQL 4.1.0 或以上版本 OR Microsoft SQL Server 2000 或以上版本 OR Postgres 8.1 或以上版本
• PHP 5.x 或以上版本并启用下列模块/链接库:
  • mbstring (Multibyte String Functions) 扩展库 (参见Installation FAQ)
  • mysql4 或 mysql5 PHP 链接库(主机商标准 - 如果你想设立自己的服务器请确保它被安装)
  • sessions - 见 http://de2.php.net/manual/en/session.installation.php (也是标配)
  • pcre (regular expressions) - 见 http://de2.php.net/manual/en/book.pcre.php (也是标配)

Please note that LimeSurvey 2.x uses different database drivers than 1.x . If you get a message not No DBO driver was found during the installation you will have to contact your webspace provider and ask them to activate one of the aforementioned database driver libraries.

可选:

• 已安裝iconv 扩展库(only for PHP 4 versions - needed for Excel export)
• GD-Library with FreeType support installed (for captchas or nice charts in statistics) 见GD-Library PHP Documentation
• 已安裝LDAP-Library (to import tokens using LDAP) 见 PHP LDAP Documentation

多数情况下网站空间商或系统管理员可以代劳。

如果你想在本机使用LimeSurvey，我们推荐XAMPP，它很容易安装配置包含 Apache, MySQL, PHP 和Perl在内的服务器。 LimeSurvey无需配置即可运行在XAMPP上。

If you want to run Microsoft's IIS server take a look at "Installation of LimeSurvey on a Windows XP machine" and "Installation on XP with IIS".

1.1 LimeSurvey主机

LimeSurvey 可运行在多数提供PHP和MYSQL的主机上。如果你需要一个即可安装版本的LimeSurvey请考虑使用LimeService, 否则也可检视我们的 LimeSurvey-兼容主机商列表.

2. 下载LimeSurvey软件包

下载 最新的稳定的LimeSurvey的zip格式压缩包 (也有gzip, bz2 和 7zip 格式压缩包) 并保存到你的本地磁盘。

3. 解压LimeSurvey 软件包

采用你喜好的压缩软件解压 zip 格式的软件包至专用目录／文件夹。请一并解压软件包原来默认的目录结构及相关档案。安装路径不应包含字符，但可以包含空格符。The path name for the installation directory should not include ( or ) characters, but may include the space character

4. 收集服务器信息

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 (ie: /home/usr/htdocs/limesurvey)
• The IP/net location of your database server (ie: localhost)
• If your database server uses a non-standard port find out which port it is.
• Your username 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.

5. Upload the files to your web server

Using your FTP program, 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.

7.1 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 or in Linux/Unix. You may wish to set the permissions on each file within the /limesurvey/admin directory to Read Only.

Hint: If you are using Linux then depending on your webserver configuration you will have to chmod the rights on the writable folders to 755 or 777. Try 755 first - if it does not work 'upgrade' to 777.

7.2 Create a database user

LimeSurvey will create a database and the tables inside it. To be able to do this it will need the username and password of a database user. In general we recommend to create 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:

8. Run the installation script

Go to "http://your.domain.com/limesurvey/admin". If you configured everything correctly the LimeSurvey installer should be starting - just follow the instructions. You will be asked if to create the database and/or create the tables inside the database. Limesurvey then creates the needed tables in the database.

9. Connect to the administration script for the first time

After the installer has finished you are done! Open your browser and enter the URL of your admin.php script. Assuming you used LimeSurvey as the directory name to store the files in, this will be something like "http://your.domain.com/limesurvey/admin/admin.php".

You should get a login screen. The default login credentials (if not changed during in the installation) are

User: admin

Password: password

You will be prompted to change the default password after you logged in. Have fun!

10. 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 on limesurvey.org or join the IRC channel:
