TWikiInstallationGuide < TWiki/

These installation steps use the Apache web server on Linux as an example. TWiki should run on other web servers and Unix systems as well.

__Note:__ These installation notes assume user =nobody= for all files manupulated by the cgi scripts (executed by the web server), and user =twiki= for all other files. You need to replace user =nobody= with an other user in case the web server executes the script with a different user ( default for Debian is =www-data= ). Also, you can substitute user =twiki= with your own user name.

	* Request the TWiki distribution (in Unix ZIP format) from http://TWiki.SourceForge.net/download.html .
	* Create directory =/home/httpd/twiki= and unzip the TWiki distribution to this directory.
	* The =twiki/bin= directory of TWiki must be set as a cgi-bin directory. Add =/home/httpd/twiki/bin= to =/etc/httpd/conf/access.conf= with only =ExecCGI= option.
	* The =twiki/pub= directory of TWiki must be set so that it is visible as a URL. Add =/home/httpd/twiki= to =/etc/httpd/conf/access.conf= with normal access options (copy from /home/httpd/html).
	* Now add =ScriptAlias= for =/twiki/bin= and =Alias= for =/twiki= to =/etc/httpd/conf/srm-conf= . Example: <br> =ScriptAlias /twiki/bin/ /home/httpd/twiki/bin/= <br> =Alias /twiki/ /home/httpd/twiki/= <br> __Note:__ The =ScriptAlias=  *must* come before the =Alias= in Apache, otherwise it will fail to correctly set up =/twiki/bin/= , due to the fact that it sees that as being just another subdirectory of the =/twiki/= alias.
	* Restart Apache by =/etc/rc.d/rc5.d/S85httpd restart= .
	* Test if the =twiki/bin= directory is cgi-enabled:
		* Enter the URL of that directory into your browser ( =http://your.domain.com/twiki/bin= ). It is not set correctly as cgi-bin in case you get something like ="Index of /twiki/bin"= . It is OK if you get a message like ="Forbidden. You don't have permission to access /twiki/bin/ on this server."=
		* Execute the =testenv= script from your browser ( =http://your.domain.com/twiki/bin/testenv= ). It should show a table of all CGI environment variables.
	* Make sure PERL and the PERL CGI library is installed on your system. Default location of PERL executable is =/usr/bin/perl= . In case PERL is installed in a different location, the first line of all perl scripts in the =twiki/bin= directory need to be changed (alternatively you can create a symbolic link from =/usr/bin/perl= ).
	* To be able to edit the perl scripts and .tmpl files it is necessary to =chown= and =chgrp -R twiki= so all the files have the owner you want.
	* The scripts execute as =nobody= . Set the file permission of all Perl scripts in the =twiki/bin= directory as executable to =-rw-r-xr-x= .
	* Set the file permission of all files below =twiki/data= to 666 ( =-rw-rw-rw-= ).
	* Set the file permission of the =twiki/data= directory and all its subdirectories to 777 ( =drwxrwxrwx= ).
	* Set the file permission of the =twiki/pub= directory to 777 ( =drwxrwxrwx= ).
	* Edit the file =twiki/bin/wikicfg.pm= and set the variables at the beginning of the file to your needs.
	* Make sure RCS is installed. In case RCS is not in the =path= environment variable, add it to =path= . Alternatively, add the full path name to the =rcs, ci, co, rlog, rcsdiff= commands in the variables of =twiki/bin/wikicfg.pm= .
	* Point your browser at http://your.domain.com/twiki/bin/view and start wiki-ing away! 
	* Note in case cgi user is __not__ =nobody= : The =*,v= RCS repository files delivered with the installation package are locked by user =nobody= . In case the user is different (e.g. =www-data= ), it is not possible to check in files, this has the effect that the topic version number does not increase when saving a topic. In this case you need to unlock all repository files and lock them as user =www-data= (check the rcs man pages), or simply delete all the repository files.
	* Security issue: Directories =twiki/data= , =twiki/templates= and all its subdirectories should be set so that they are *not* visible as a URL. (Alternatively, move the directries to a place where they are not visible, and change the variables in =twiki/bin/wikicfg.pm= accordingly)
	* Enable email notification of topic changes, <A href="TWikiDocumentation#notification">(3)</A> has more.
	* Add the <a href="http://TWiki.SourceForge.net/cgi-bin/view/Main/PoweredByTWikiLogo">PoweredByTWikiLogo</a> if TWiki is installed on a public web server.

	* Optional: You can add new rendering rules or new %<nop>variables%. To insure an easy upgrade of TWiki it is recommended to do this customization in =twiki/bin/wikicfg.pm= , not =twiki/bin/wiki.pm= .

	* Optional: If you are on a public server and you would like to authenticate users:
		* Rename file =.htaccess.txt= in the =twiki/bin= directory to =.htaccess= and change it to your needs. For details consult the HTTP server documentation (for Apache server: <a href="http://www.scs.nevada.edu/cs/documents/web/htaccess.html">[1]</a>, <a href="http://www.mcs.kent.edu/system/web_help/htaccess/introduction.html">[2]</a>, <a href="http://www.apache.org/docs/mod/directives.html">[3]</a>). __Note:__ In case =.htaccess= does not have any effect you need to enable it: Add "AllowOverride All" to the Directory section of =access.conf= for your =twiki/bin= directory.
		* Copy the TWikiRegistrationPub topic to TWikiRegistration. You can customize the topic if needed. __Note:__ You can delete or add new input variables to the registration form. The =name=""= parameter of the input tags must start with: ="Twk0..."= (if this is an optional entry), or ="Twk1..."= (if this is a required entry). This will ensure that the fields are processed correctly.

	* Optional: You can automatically generate usage statistics for all webs. To enable this:
		* Make sure variable =$doLogTopicView, $doLogTopicSave and $doLogTopicUpload= in =wikicfg.pm= are set. This will generate log entries in file =twiki/data/log&lt;date&gt;.txt= .
		* Topic WebStatistics must be present in all webs where you want to have statistics. You can use the topic in the Main web as a template.
		* Call the =twiki/bin/statistics= script from a cron job, once a day is recommended. This will update the WebStatistics topics in all webs.
		* __Attention:__ The script must run as the same user as the CGI scripts are running, which is user =nobody= on most systems. Example crontab entry: <br> =0 0 * * * (cd /path/to/TWiki/bin; ./statistics &gt;/dev/null 2&gt;&amp;1)=
		* There is a workaround in case you can't run the script as user =nobody= : Run the utility =twiki/bin/geturl= in your cron job and specify the URL of the =twiki/bin/statistics= script as a parameter. Example: <br> =0 0 * * * (cd /path/to/TWiki/bin; ./geturl mydomain.com /urlpath/to/TWiki/bin/statistics &gt;/dev/null 2&gt;&amp;1)=
		* The =twiki/bin/statistics= script can also be executed as a CGI script, just enter the URL in your browser. Examples:
			* Update current month for all webs: <br> =http://mydomain.com/twiki/bin/statistics=
			* Update current month for Main web only: <br> =http://mydomain.com/twiki/bin/statistics/Main=
			* Update January 2000 for Main web: <br> =http://mydomain.com/twiki/bin/statistics/Main?logdate=200001=

	* To create a new web:
		* Use a name for the web consisting of characters =A..Z= , =a..z= but *not* in WikiNotation.
		* Create a new template directory under =twiki/templates= .
		* Create a new data directory under =twiki/data= and check the file permission of the directory.
		* Copy the files =WebHome.txt= , =WebPreferences.txt= , =WebNotify.txt= , =WebSearch.txt= and =WebStatistics.txt= from the =twiki/data/Main= directory to the new data directory, preserving the original files' owner, group and permissions ( on Unix use =cp -p= ). The data files must be writable by the owner the CGI scripts are running on ( usually =nobody= ). Hint: You can set permissions of =.txt= and =.txt,v= files to =-rw-rw-rw-= and then edit the topic using your browser, RCS will restore the file permission correctly when saving the topic.
		* Add the new web to the web list (on top of each topic) by editing the site-level preferences %MAINWEB%.%WIKIPREFSTOPIC%:
			* Add the new web to the WIKIWEBLIST variable.
		* Add the new web to the web table (at the bottom of each WebHome topic) by editing the %MAINWEB%.TWikiWebsTable topic.
		* Change the web preferences by editing the <nop>WebPreferences topic of the new web:
			* Set the WEBBGCOLOR variable to a color of your taste. The number represents the unique color for the web (consult an HTML book for colors.)
			* Customize the WEBTOPICLIST variable to contain the web specific links you prefer.
			* Optional: Set the WEBCOPYRIGHT variable to have a web-specific copyright text (at the bottom of each topic).
		* If needed, create customized templates in the new templates directory. (Non existing templates are inherited from =twiki/templates= )
		* If you want to use a category table, copy the three files =twikicatitems.tmpl= , =twikicatedit.tmpl= and =twikicatview.tmpl= from the =twiki/templates/Know= directory to the new templates directory, and customize it. The TWiki Category Table section has more.
		* In case you want usage statistics for this web: Copy file =WebStatistics.txt= from the =twiki/data/Main= directory to the new data directory. Edit topic <nop>WebStatistics in the new web and delete old usage entries.
