| Component | Name, version | Comment |
|---|---|---|
| Operating System | Windows 2000 | Should also work for Windows NT |
| Web Server | Apache 1.3.26 | Windows-specific security holes fixed in this build (check latest version at http://httpd.apache.org, but don't use Apache 2.0 yet) |
| Unix tools | Cygwin 1.3.9 | Simplest way to get a whole set of required tools |
| Perl | Cygwin perl-5.6.1-2 | Comes with Cygwin |
| RCS | Cygwin rcs-5.7-2 | Comes with Cygwin, includes a file corruption bugfix |
Major version upgrades, such as Apache 2.0 and Perl 5.8, are very likely to cause problems - for example, Apache 2.0 is unable to authenticate (see TWiki:Support.FailedAuthenticationWithApache2OnWinNT) users created by the current TWiki user registration script (due to a feature being removed in 2.0), and Perl 5.8 may introduce issues due to its Unicode features. Even though the Apache group says that Apache 2.0 is the best version, that's not true for TWiki.
TWiki.cfg, and is probably a simpler choice if you need an easy way to install mod_perl (see TWiki:Codev.ModPerl). TWiki:Codev.ActiveState Perl can be substituted without too much hassle, and in fact the same TWiki.cfg can be used for both TWiki:Codev.ActiveState and Cygwin Perl.
$ : Cygwin DLL version is the number in 1.3.x format $ uname -r $ less c:/your-apache-dir/Announcement $ perl -v $ rcs -VIf you have an older version of any component, do yourself a favour and upgrade it as part of the install process.
nano, a non-GUI editor, but if you prefer to use a GUI editor, you should first install PFE, a freeware editor that supports Unix format files. PFE is available on download.com and Simtel.
Another good TWiki:Codev.OpenSource editor is SciTE (aka WSciTE), available at http://www.scintilla.org/SciTE.html.
c:/apache almost everywhere in Windows - try it in a File Open dialogue box. The main exception is the Win2000 cmd.exe command line shell - here, you must use double quotes around forward slashes, e.g. dir "c:/apache" will work fine.
The reason this matters is that '\' is a special character to Perl and other tools, so it's much easier to use '/' everywhere.
c:/apache format, but it also provides a more Unixlike syntax, e.g. /usr/bin/rcs.exe, because some Unix tools ported onto Cygwin only support the Unix format.
When you launch a Cygwin shell, your existing PATH variable is translated from the Windows format to the Unix format, and the ';' separators in the Windows PATH are changed into ':' separators as required by Unix. A Cygwin tool (e.g. Cygwin Perl or Cygwin RCS) will always use the Unix PATH format, and will accept Unix format pathnames.
httpd.conf file. There have been some security-related bugs in Apache with long pathnames, which are a bit more likely if you use spaces, so it's best to just avoid long names and using spaces.
ls, egrep, and RCS tools that it (typically) launches with the bash shell.
If you need to use spaces in file names (not recommended), you may be able to put double quotes around the file name in the TWiki.cfg file - however, it's not clear whether all the TWiki code would work with this.
apache_1.3.X-win32-x86-no_src.msi where 'X' is 20 or higher
instmsi.exe) from the Apache Win32 download page - this enables you to install .MSI files. You may need to update the .MSI Installer if you have an old version under NT.
c:\ as the installation directory - this actually installs Apache into c:\apache (if you specify c:\apache, it installs into c:\apache\Apache). Putting Apache into c:\Program Files is not recommended for easy editing of Apache config files from Cygwin.
apache -k start -n apache) or standalone (by typing apache -k start)
apache -k restart for standalone Apache process running in another window
apache -k restart -n apache for Apache running as a Win2000 service (-n gives name of service)
apache -k stop.
setup.exe in a directory, e.g. c:\download\cygwin-dist.
Now run the Cygwin setup.exe file - this will also install Perl and RCS in one fell swoop.

lynx if you are upgrading from an older Cygwin installation (to avoid annoying DLL messages) - if you want Lynx, read the Cygwin FAQ entry and upgrade libncurses5.
gcc, which is required for simple installation of Perl modules that use the C language. Something like 20 to 30 MB of free disk space should be enough for Cygwin, but I didn't test this (try a du -k / after a new install and let me know the last figure).
bash shell, which has command line editing features
bash will 'complete' the name. If bash beeps at you, hit TAB again to see the files/directories that match the name so far, and type a bit more before hitting TAB. This saves a lot of time!
rcs -V - you should see the RCS version, 5.7
perl -v - you should see cygwin mentioned in the first line, and the Perl version, 5.6.1
grep home /etc/passwd - you should see some output.
$ mkdir /twiki /c c:/twiki $ mount -b -s c:/twiki /twiki $ mount -b -s c:/ /c $ mount -b -c /cygdrive $ mount Device Directory Type Flags C:\cygwin\bin /usr/bin system binmode C:\cygwin\lib /usr/lib system binmode C:\cygwin / system binmode c:\twiki /twiki system binmode c: /c system binmode
/twiki (known as a 'mount point') to map onto c:/twiki and for that directory tree to always be in binary mode, and does the same for /c, mapping it onto c:/. The last-but-one command sets binary as the default for any unmounted drives (e.g. z:/, aka /cygdrive/z).
mount say 'binmode' under Flags
C:\cygwin directories do not, you should uninstall and then re-install Cygwin to ensure that binary attachment uploads will work.
/twiki/bin/view or /c/apache/Announcement - see the Cygwin documentation for more details on this.

c:/twiki directory.
8. Install TWiki
Unzip the ZIP file under c:/twiki using WinZip, or by going into Cygwin and doing the following - you can hit the TAB key to complete filenames after you've typed the first part:
$ cd /twiki $ unzip TWiki20011201.zip
'nano', or the Windows PFE editor, unless you already know 'vi'), edit c:/apache/conf/httpd.conf as follows - this tells Apache where TWiki lives, and removes the need to tinker with the Windows 2000 environment settings.
nano -w filename - this turns off wrapping of long lines.
c:\temp directory, by typing mkdir c:\temp in a DOS command line window
# Change this to point to the Apache administrator (e.g. you) ServerAdmin you@yourdomain.com # Replaces DocumentRoot "C:/apache/htdocs" DocumentRoot "C:/twiki" # Replaces <Directory "C:/apache/htdocs"> <Directory "C:/twiki">

# Adjust TZ for your server timezone, e.g. EST5EDT - put the non-daylight-savings
# timezone code first (e.g. EST or GMT), followed by the number of hours that it's behind GMT

SetEnv TZ GMT0BST
SetEnv RCSINIT -x,v/
# Adjust TEMP and TMP for your server and create directories if necessary
SetEnv TEMP c:/temp
SetEnv TMP c:/temp
SetEnv LOGNAME system
SetEnv HOME c:/twiki
</IfModule>
2. Configure Apache (part 2)
Add an AddHandler line to the <IfModule mod_mime.c> section of httpd.conf - this removes the need to rename all the TWiki CGI scripts later in the installation.
#
# Document types
#
<IfModule mod_mime.c>
# TWiki setup - avoid renaming scripts
AddHandler cgi-script .
</IfModule>
c:/twiki/lib/TWiki.cfg (or in Cygwin terms, /twiki/lib/TWiki.cfg) as follows:
c:/twiki format pathnames for Cygwin, given the above binmode setup, but I have not tested this fully - a Cygwin Perl test script does generate binary mode files in this configuration, so it should work with RCS as well (really need a small RCS file corruption test case). Watch out for RCS file corruption carefully if you do try c:/twiki pathnames with Cygwin, and do report your experiences...
fgrep and egrep to grep, requiring the settings for these commands to point directly to grep (with suitable flags to provide fgrep and egrep behaviour).
# variables that need to be changed when installing on a new server:
# ==================================================================
# http://your.domain.com/twiki : link of TWiki icon in upper left corner :
$wikiHomeUrl = "http://yourdomain.com/bin/view";
# Host of TWiki URL : (Example "http://myhost.com:123")
$defaultUrlHost = "http://yourdomain.com";
# /twiki/bin : cgi-bin path of TWiki URL:
$scriptUrlPath = "/bin";
# /twiki/pub : Public data path of TWiki URL (root of attachments) :
$pubUrlPath = "/pub";
# NOTE: Next three settings should be valid absolute pathnames using Cygwin; if using
# TWiki:Codev.ActiveState Perl, use z:/twiki format pathnames if your TWiki directory is not on C:.
# Public data directory, must match $pubUrlPath :
$pubDir = "/twiki/pub";
# Template directory :
$templateDir = "/twiki/templates";
# Data (topic files) root directory :
$dataDir = "/twiki/data";
....
# Set ENV{'PATH'} explicitly for taint checks ( #!perl -T option ) :
# (Note: PATH environment variable is not changed if set to "")
# On Windows, $safeEnvPath needs only one component, the directory where RCS is installed
# - used by 'rcsdiff' to run 'co' program, so PATH must be correct.
# Unix/Linux setting:
# $safeEnvPath = "/bin:/usr/bin";
# Using Cygwin perl, so can use Unix-like paths, with ':' as separator.
# Note that /usr/bin and /bin are identical due to default /usr/bin mount
# in Cygwin. Must NOT use 'c:/foo' type paths, as ':' is taken as separator
# meaning that 'c' is interpreted as a pathname, giving Perl taint error.
$safeEnvPath = "/bin";
# If using ActiveState perl, use Windows paths instead
# $safeEnvPath = "c:/cygwin/bin";
...
# RCS directory (find out by 'which rcs') :
$rcsDir = "c:/cygwin/bin";
...
# Unix egrep command :
$egrepCmd = "/bin/grep -E";
# Unix fgrep command :
$fgrepCmd = "/bin/grep -F";
For the cookbook install using Cygwin Perl, there's no more TWiki.cfg editing to be done, so you can get onto the next section.
# NOTE: When using ActiveState Perl, you must specify # a full Windows-style pathname, using '\\' for backslashes, # for the ls, egrep and fgrep commands, because Cygwin's shell # is not used - forward slashes are OK in Windows everywhere # except in the cmd.exe shell. Drive letters are OK - e.g. # 'c:\\foo\\ls' will work. When using Cygwin perl, just # use the default '/bin/ls' type settings. # # Unix ls command : $lsCmd = "c:\\cygwin\\bin\\ls"; # Unix egrep command : $egrepCmd = "c:\\cygwin\\bin\\grep"; # Unix fgrep command : $fgrepCmd = "c:\\cygwin\\bin\\grep";
perl line, you can restore from the .backup directory and re-run the command, as it will only edit the original files, not the backups with '~' suffixes.
$ cd /twiki/bin $ ls attach geturl oops rdiff save testenv viewfile changes installpasswd passwd register search upload edit mailnotify preview rename statistics view $ mkdir .backup $ cp * .backup $ head -1 view #!/usr/bin/perl -wT $ perl -pi~ -e 's;#!/usr/bin/perl;#!c:/cygwin/bin/perl;' *[a-z] $ head -1 view #!c:/cygwin/bin/perl -wT $ ls attach geturl oops rdiff save testenv viewfile~ attach~ geturl~ oops~ rdiff~ save~ testenv~ view~ changes installpasswd passwd register search upload changes~ installpasswd~ passwd~ register~ search~ upload~ edit mailnotify preview rename statistics view edit~ mailnotify~ preview~ rename~ statistics~ viewfileIf for some reason the edit goes wrong, just type
cp .backup/* . (while within the bin directory) to restore the original distribution files. Use ls -a to see the .backup directory, and ls -a .backup to view its contents.
Optional step: you can do 'rm *~' to clean out the backups made by Perl, but that's not essential as all the original files cannot be executed. If you do this, type the command very carefully, as a space after the '*' will wipe out all files in this directory!
5. Minor changes to TWiki scripts
As an interlude, you now need to make some minor edits to files in the c:/twiki/bin directory, using a suitable editor (remember to use nano -w filename if you prefer nano to vi - or just use the Windows PFE editor).
register script in /twiki/bin - change line 200 to read as follows (insert the MIME::Base64:: part):
return $user . ':{SHA}' . MIME::Base64::encode_base64(Digest::SHA1::sha1($passwd));
testenv, see TWiki:Codev.CookbookActivePerlTestenv
register script to work properly. Fortunately, there is an automated tool that makes it easy to do this - it's called cpan, and goes to the Perl module archive site, http://www.cpan.org/, to download all required modules, and then build and install them. Here's what you need to do:
First of all, you need to get the cpan tool configured and working - this is only necessary once. From the Cygwin shell, type the following (putting the export command in ~/.profile is recommended to make this setting persistent). Without the TEMP variable, some modules may fail to install on Windows 2000 and higher.
$ export TEMP=/c/temp $ cpan Lots of questions about configuration and preferences - just hit Enter until you get to the questions about mirror sites, but answer the questions about FTP proxies etc if you are behind a proxy-based firewall. The CPAN tool will fetch a series of files, some quite large, as part of this setup process, so be patient...NOTE: If you are behind a non-proxy-based firewall that requires the use of passive FTP, the initial downloads of files using Net::FTP may appear to hang - just wait 5 or more minutes, however, and the CPAN tool should eventually hit on
ncftpget, which is part of Cygwin and does work OK. If this doesn't work and you are behind a typical NAT-based firewall, try doing the following at the Cygwin shell before running cpan - this forces Net::FTP to use passive FTP, letting it get through such firewalls:
$ export FTP_PASSIVE=1If this works, add this line to your
~/.profile file for future use.
Once some initial files are downloaded, you are asked to select your continent and country, and then mirror sites - just type the number of the mirror sites you want to use (pick a few in case one is down):
... (28) Turkey (29) Ukraine (30) United Kingdom Select your country (or several nearby countries) [] 30 (1) ftp://cpan.teleglobe.net/pub/CPAN (2) ftp://ftp.clockerz.net/pub/CPAN/ (3) ftp://ftp.demon.co.uk/pub/CPAN/ (4) ftp://ftp.flirble.org/pub/languages/perl/CPAN/ (5) ftp://ftp.mirror.ac.uk/sites/ftp.funet.fi/pub/languages/perl/CPAN/ (6) ftp://ftp.plig.org/pub/CPAN/ (7) ftp://mirror.uklinux.net/pub/CPAN/ (8) ftp://sunsite.doc.ic.ac.uk/packages/CPAN/ (9) ftp://usit.shef.ac.uk/pub/packages/CPAN/ Select as many URLs as you like, put them on one line, separated by blanks [] 4 7 8 Enter another URL or RETURN to quit: [] New set of picks: ftp://ftp.flirble.org/pub/languages/perl/CPAN/ ftp://mirror.uklinux.net/pub/CPAN/ ftp://sunsite.doc.ic.ac.uk/packages/CPAN/Eventually, you'll get to the CPAN tool's shell prompt, where you need to install a few modules - the tool will do all the work for you.
make and gcc packages, which are required by the CPAN installer (gcc is required for modules that include C language code) - you can install them now by launching Cygwin's setup.exe from c:/download/cygwin-dist (no need to exit the CPAN installer).
cpan shell -- CPAN exploration and modules installation (v1.59_54) cpan> install Net::SMTP May already be installed - if it is, try 'force install', since it's useful to be able to set firewall and passive FTP configuration when using Net::FTP. Make sure you answer 'Y' to the question about whether you want to configure this package. cpan> install Digest::SHA1 Lots of output about how CPAN finds, builds and installs the module - watch for any errors, though it should work fine if you have installed the Cygwin packages listed above (particularly 'gcc' and 'make'). cpan> install MIME::Base64 May already be installed.
testenv script doesn't work, go back and check the configuration of the Apache httpd.conf file, and TWiki.cfg. Have a look at the Apache error log, c:/apache/logs/error_log, and the TWiki error log, /twiki/data/log*.txt.
rcs -u and rcs -l, but it's a painfully manual process. Instead, just use Perl again to mass-edit all the RCS files, as follows:
$ cd /twiki/data $ : Make a backup of all files $ tar czvf all-files.tar.gz */* $ : Test edit a single file to check your typing $ perl -pi~~~ -e 'NR <= 10 && s/nobody:/system:/ ' Main/WebIndex.txt,v $ diff Main/WebIndex.txt,v Main/WebIndex.txt,v~~~ 5c5 < system:1.2; strict; --- > nobody:1.2; strict; $ : Now edit all the RCS files at once - use cursor-up to recall previous command $ perl -pi~~~ -e 'NR <= 10 && s/nobody:/system:/ ' */*,v $ : Check for any remaining files not edited $ grep 'strict;$' */*,v | grep -v system $ : Clean up - type this very carefully $ rm */*~~~
tar xzvf all-files.tar.gz and all your files, both .txt and .txt,v, will be back as they were before the edits.
SMTPMAILHOST to an SMTP email host that is reachable and currently working. Otherwise you'll get a confusing message from TWiki when registering new users or running mailnotify (for WebNotify), along the lines of:
Software Error: Can't call method "mail" on an undefined value at ../lib/TWiki/Net.pm line 187.There are other settings to be made in TWikiPreferences, e.g. the
WIKIWEBMASTER and (probably) the SMTPSENDERHOST (normally your mail server or TWiki server). See the TWikiInstallationGuide for more details, what's listed here is just enough to let you run the basic tests.
http://yourdomain.com/bin/testenv and check for warnings
view script) - click around a few pages and make sure the links are OK
rdiff script) - click on the Diffs link and on the '>' links at bottom of page
register script to create a new user entry in /twiki/data/.htpasswd (the Apache password file), ability to send email via Net::SMTP, and whether SMTPMAILHOST was set correctly in TWikiPreferences.
tail -30 /c/apache/logs/error_log to see last 30 errors from Apache
error_log file to see if there are any RCS errors so far
ls and grep are working
ls and grep are working
/twiki/pub directory.
error_log file again
httpd.conf file, and TWiki.cfg. Have a look at the Apache error log, c:/apache/logs/error_log, and the TWiki error log, /twiki/data/log*.txt, and if necessary enable debugging on selected scripts (the commands are right at the top of each script) - the results go into /twiki/data/debug.txt. There is also a /twiki/data/warning.txt file that contains less serious messages.
See TWiki:Codev.TWikiPatches in case there are patches (i.e. specific code changes) for particular problems that may affect you (e.g. TWiki:Codev.ChangePasswordOnWin2K).
If you find that the Index feature doesn't work, or topic name searches fail, you should check you have set $egrepCmd and $fgrepCmd correctly, as mentioned above.
#!/bin/something). This is what has been used for this cookbook.
c:/twiki type filenames (i.e. Windows format) since you are using Apache for Windows.
mod_perl - this is somewhat more complex and follows a different model, so it's best to get some experience with TWiki, Apache and Perl first.
.htaccess file and c:/apache/conf/httpd.conf) always use Windows format paths, with forward slashes, e.g. c:/twiki
c:/cygwin/bin/perl
/twiki (using Cygwin Perl as per this cookbook)
c:/twiki
/twiki
