A shared hosting account have some restrictions :

  • Daemon mode is forbidden, or cannot be activated. So you must use CGI mode.
  • You must fit in the server environment : OS version, libraries, installed packages.
  • The OS version is generally a stable version, but not the latest version.

Download a GeneWeb package

Directories and files

The following applies to 1&1 hosting, and may differ on other hostings: Under the root directory where CGI scripts may run, we have : !File:captur477.jpg

The directories :

? Beside the CGI-root directory
mybases The bases directory
? In the CGI-root directory
basesxg An alternative bases directory
css A copy of the gw/css directory. This directory is used by the Apache server.
gw The gw directory of the Geneweb distribution

No change, except give the "exec" permission on the files gw/gwd, gw/gwsetup, and files used by gwsetup (gw/gwc*, gw/gwu,gw/consang, gw/update_nldb) The gwd.arg file is *empty*.

gwenv The gw directory of the Geneweb-5 distribution

On this web site, we can easily switch between the 2 last versions of GeneWeb.

igw The images directory for Geneweb-5
images A directory where copies of gw/images/gwback.jpg, gw/images/gwlogo_bas.png
pub A directory where are readable copies of the CGI scripts (this website is a demo site) :

launch Geneweb-5 launch Geneweb-6 check if Geneweb-6 can be launched

And the files :

issue6.cgi A test script which

- displays information about the environment in the server - checks the gwd binary file : size and md5sum

issue5.cgi The same script, but for the GeneWeb-5 version
gw6.cgi The CGI script which launches GenWeb-6
gw5.cgi The CGI script which launches GenWeb-5

Parameters of the CGI script

PWD=$(pwd)
LNG="fr"
GENEWEBSHARE=$PWD/gw
GENEWEBDOC=$PWD/gw/doc
GENEWEBDB=$PWD/../bases
DAEMON=$GENEWEBSHARE/gwd
LOGFILE=$GENEWEBDB/gw.log

Main settings :

  • 1 get the CGI working directory
  • 2-7 set the main parameters
  • 5 $GENEWEBDB does not need to be accessed by the HTTP server.

It must be protected either by a .htaccess file, either by a location out of the HTTP server scope.

  • 7 a log file is useful when there are problems, but do not forget to delete it after downloading.
OPTIONS="-blang -robot_xcl 40,70 -max_clients 15 -conn_tmout 120 -min_disp_req 30 -images_url http://myserver.net/gw/images"
# -allowed_tags $GENEWEBDB/tags.txt
cd $GENEWEBSHARE
$DAEMON -hd$GENEWEBSHARE -dd$GENEWEBDOC -bd$GENEWEBDB -lang$LNG -log$LOGFILE -cgi $OPTIONS  2>/dev/null

Options and launching

  • 1 OPTIONS
-robot_xcl to protect your data from HTTrack or WebSite Extractor
-conn_tmout for statistics on the bottom line
-images_url icons and images are not sent by GeneWeb, but par your HTTP server (not CGI).
-allowed_tags another useful option, if you use HTML tags not in default_good_tag_list
  • 3 cd $GENEWEBSHARE. I am not sure it is really needed.
  • 4 launch GeneWeb

An alternative installation on 1&1

Some general comments

Installing GeneWeb on a remote shared server is a little bit (but not that much) more complex than on a personal computer. GeneWeb is a totally self contained package, therefore does not depend on additional libraires. On a server, GeneWeb cannot execute in daemon mode (Unix aficionados will understand), and must be launched in CGI mode. To that extent, a server based installation requires prior installation of a (standard) HTTP server (typically Apache), access to the CGI repository of this server and some control over the access rights to the various folders and files. Installing or verifying your HTTP server is not part of this discussion.

A second restriction of GeneWeb on a server is that gwsetup cannot be used (mainly for security reasons). It is therefore necessary to use command lines on the remote server through a ssh window or any other remote access tool of your choice. It is also necessary to have access to a upload mechanism from your personal machine to the server through classical Unix/Linux command lines, or through a ftp client such as Filezilla. A section below will describe in detail a shell script performing upload to the server of a complete fresh copy of a base sitting on your personal computer.

Folders and files

The first important file for your installation is the welcome page of your HTTP server, by default index.html sitting at the root of your server. After personalization of this welcome page, you should verify that you can view it by typing the name (or IP address) of your server in the URL window of your browser.

The second important item is the CGI folder containing the executable files invoqued through URLs. This folder is typically called cgi-bin and also sits at the root of your HTTP server. If this folder contains an executable file named test-cgi.sh as shown below:

(uiserver):u723:~ > cd cgi-bin
(uiserver):u723:~/cgi-bin > cat test-cgi.sh
#!/bin/sh
echo 'Content-type: text/htm'
echo  
echo '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"   '
echo '   "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">  '
echo '<html xmlns="http://www.w3.org/1999/xhtml">  '
echo '<body>'
echo 'This is a test for cgi commands'
echo '</body>'
echo '</html>'
(uiserver):u723:~/cgi-bin > chmod 755 test-cgi.sh # turn this file into executable
(uiserver):u723:~/cgi-bin >./test-cgi.sh
Content-type: text/htm'

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"   
   "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">  
<html xmlns="http://www.w3.org/1999/xhtml">  
<body>
This is a test for cgi commands
</body>
</html>
(uiserver):u723:~/cgi-bin >

then typing in the URL window of your browser the following text

your_server_name/cgi-bin/test-cgi.sh 

should result in the text This is a test for cgi commands appearing in your browser window (provided you have done a chmod 755 test-cgi.sh on the remote server).

You must reach this level of functionality to proceed.

At the root of your server, create two additional folders GeneWeb and Documents.

  • The first folder will contain all GeneWeb related files (binaries, bases, images, ...) and need not or should not be accessible with the HTTP server,
  • The second folder will contain any other documents that you may want to share with the visitors of your site.

At this time, we have the following situation:

The GeneWeb folder

The GeneWeb folder contains one or more versions of GeneWeb (geneweb-6.08 and geneweb-7.00 in our example), and the bases folder.

Each geneweb-x.yy folder has the same structure, containing a copy of the distribution folder resulting from the compilation of GeneWeb. You can upload with ftp this folder, or you can compile yourself GeneWeb directly on your server, but this necessitates the installation of Ocaml and camlp5 (see Ocaml).

Gwd is a symbolic link to the current version of GeneWeb (7.00 in our example).

Each of the gwd-x.yy file is a shell script that launches gwd with the appropriate parameters:

#!/bin/sh
DIR=~/GeneWeb/geneweb-6.08/gw
BASE_DIR=~/GeneWeb/bases
OPTIONS="-robot_xcl 19,60 -allowed_tags ./tags.txt -hd ./"
cd $DIR
./gwd -cgi  $OPTIONS   -bd ../../bases   > ./gwd.log 2>&1

To change your server to another version of GeneWeb (7.00 for instance), you should do the following:

cd cgi-bin
rm -f Gwd
ln -s Gwd-7.00 Gwd

The bases folder

Folder structure for GeneWeb bases (Genealogy data).

The base folder should contain the same information structure as in the case of installation on a personal computer:

  • one or several base.gwb folders.
  • one or several base.gwf files.
  • cnt containing access count data.
  • etc containing template text files used in priority over the generic gw/etc files (see header).
  • images containing for each base photos associated with each person (first_name.occ.last_name.jpg).
  • lang containing some base specific language relates template text files (lexicon for instance).
  • src containing for each base text files and image files inserted in notes with the m=SRC command (see gwd commands).
  • wiz.auth as many wizards and friends authorization files as specified for each base in their respective .gwf parameter file.

(Note that the picture on the right has been taken off a personnal computer where the bases are stored in a folder names GeneWeb-Bases, as opposed to bases in the remote server structure proposed here).

A script to upload a copy of a base

(Test and report for errors or improvements are welcome Henri83 (talk) 23:32, 23 October 2015 (CEST))

The script in this page takes a base_name as an argument, and optionally images or src. It uploads a fresh base on your server, or a fresh copy of the images/base or src/base folders. It performs the following steps:

  • creates a fresh base.gw file from the base on your personal computer.
  • extracts a listing of the content of bases/images/base bases/src/base and bases/src/base/images in three ls-xxx.txt files.
  • creates a remote.sh file (see below).
  • creates a tar file containing $BASE.gw, history remote.sh and the three ls-*.txt files above.
  • sends the tar file to the remote server.
  • triggers on the remote server unfolding of the tar file and execution of remote.sh. The result of this remote execution should be a mail containing the remote.log and three diff between images folders.

This procedure saves the previous folder of the base or its images and src folders with a "yy-mm-dd" date tag. As time progresses, you may want to clean-up this accumulation of saves.

remote.sh for base update

The shell script below is executed on your remote server, and installs your base at the proper location (according to the overall set-up described here).

#!/bin/sh
# BASE will be replaced by the appropriate name by sed
cd
DATE=$(date +"%Y-%m-%d-%T")

echo 'Error log of update for base: BASE' > ./remote.log
echo $DATE >> ./remote.log

# Save current version 
cd ~/GeneWeb/bases 2>> ./remote.log
if [ -d ./BASE.gwb ]  # do it only if folder exists
then
  mv ./BASE.gwb  ./BASE-$DATE.gwb 2>> ./remote.log
fi

# Extract new base from .tar file
tar xf ~/BASE.tar 2>> ./remote.log
# rebuild BASE from .gw file
../geneweb-VERS_S/gw/gwc1 -f -o BASE BASE.gw 2>> ./remote.log
../geneweb-VERS_S/gw/updnldb BASE 2>> ./remote.log

if [ -f ./BASE.gwb ] # do it only if file exists
then
  cp -f ./BASE-$DATE.gwb/history ./BASE.gwb 2>> ./remote.log
fi
if [ -f ./BASE.gwb ]  # do it only if file exists
then
  cp -f ./BASE-$DATE.gwb/forum   ./BASE.gwb 2>> ./remote.log 
fi
# done
cd >> ./remote.log

# Create a link to css.txt in the bases/src folder
ln -s -f ~/GeneWeb/geneweb-$VERS/gw/etc/css.txt ~/GeneWeb/bases/src/BASE/css.txt 2>> ./remote.log

# compute diffs between server and personal computer for image folders
if [ -d ~/GeneWeb/bases/images/BASE ]     # do it only if folder exists
then
  ls ~/GeneWeb/bases/images/BASE          > ./ls-personnes-serveur.txt
fi
if [ -d ~/GeneWeb/bases/src/BASE/ ]       # do it only if folder exists
then
  ls ~/GeneWeb/bases/src/BASE/*.txt       > ./ls-src-files-serveur.txt
fi
if [ -d ~/GeneWeb/bases/src/BASE/images ] # do it only if folder exists
then
  ls ~/GeneWeb/bases/src/BASE/images      > ./ls-images-serveur.txt
fi

echo 'Personnes diff serveur vs local' >> ./remote.log
diff ./ls-personnes-serveur.txt ./ls-personnes.txt >> ./remote.log
echo 'Src files diff serveur vs local' >> ./remote.log
diff ./ls-src-files-serveur.txt ./ls-src-files.txt >> ./remote.log
echo 'Images diff serveur vs local' >> ./remote.log
diff ./ls-images-serveur.txt ./ls-images.txt >> ./remote.log

/usr/bin/mail -s 'Update error log' 'ADDRESS' < ./remote.log
rm -f ./remote.*

remote.sh for images or src update

The shell script below is executed on your remote server, and installs the images or src/images folders for your base at the proper location (according to the overall set-up described here).

Depending on the size of your images folders, and on the number of new images requiring upload, you may prefer to upload images individually with your preferred ftp client rather than doing the bulk upload proposed here. Remember that the base upload script performs a comparison between the images folders on your personal computer and your server.

DATE=$(date +"%Y-%m-%d-%T")

if [ -e ./images.tmp ]
then
  FILES="images"
  rm -f ./images.tmp
fi
if [ -e ./src.tmp ]
then
  FILES="src"
  rm -f ./src.tmp
fi

echo "Error log of update for $FILES of base: BASE" > ./remote.log
echo "`date`" >> ./remote.log 

# Save current version then move new version
if [ -d ~/GeneWeb/bases/$FILES/BASE ]  # do it only if folder exists
then
  mv ~/GeneWeb/bases/$FILES/BASE  ~/GeneWeb/bases/$FILES/BASE-$DATE 2>> ./remote.log 
fi
mv ./BASE ~/GeneWeb/bases/$FILES 2>> ./remote.log 

/usr/bin/mail -s 'Update error log' 'ADDRESS' < ./remote.log
rm -f ./remote.*

Debugging your remote server

Debugging your remote server may be tricky, but some systematic approach and several tools will help.

  • Verify first that your HTTP server works properly. This is achieved by typing your_server_name in the URL window of your browser which should return the content of index.html.
  • Verify that the cgi mechanism works. This is achieved by typing your_server_name/cgi-bin/test-cgi.sh as seen above (see #Folders and files).
If your server returns a "Internal server error", several hypothesis should be examined:
  • Your script test-cgi.sh does not work properly. Run it directly on a terminal window by typing ./test-cgi.sh (see #Folders and files).
  • The first two lines returned by your test-cgi.sh script are not exactly as shown (the second one should be a blank line).
  • Examine the HTTP server log file on your server by typing:
tail ~/logs/access.logs.current
(your environment may store access logs somewhere else, but this is the most likely place)
Examination of the log file may give you a hint as to the nature of your problem.
  • Another typical issue is that of ownership of the various files associated with GeneWeb. In the case described here, ownership is user and group ownership is ftpusers. Depending on the specific method you have used to install GeneWeb, this may vary. Some discussions on the Yahoo! group forum about GeneWeb mentions geneweb for group ownership!
  • Lastly, you may want to look at the gwd log file if your GeneWeb server works only partially (welcome page is ok, but other pages do not work properly). This log file is specified in the gwd launch command. In our example, it sits at
$DIR/gwd.log

where $DIR depends on the specific version of GeneWeb you are currently running (see details in #The cgi folder section above).
