• PHP 5.1.0+
• MediaWiki 1.6alpha1+
• LaTeX
• ImageMagick
• dvipng
• sudo v1.6.8 with support for NOEXEC compiled in (verify by sudo -V), either:
  • build from source, or
  • RPM that worked for RHEL4
• GhostScript (part of RHEL4) - required by dvipng
• libgd (gd, part of RHEL4) - required by dvipng
• cd /usr/lib; ln -s ./libgd.so.2.0.0 ./libgd.so gd.h, etc (gd-devel, part of RHEL4)
• Gnuplot - plot
• Graphviz - graph

Installation

• Create the user wikitex:

# useradd -M -s /sbin/nologin wikitex

• To prevent legitimate files from exceeding the disk quota, set up a crontab to purge unused files.

# crontab -u <apache-user> wikitex.cron

• Remove any WikiTeX cruft from /etc/sudoers, and issue:

# cat wikitex.sudoers >> /etc/sudoers

and then:

# visudo -c

If there are parse errors, run `visudo' and correct any mistakes.

• Edit /usr/share/texmf/web2c/texmf.cnf, modifying the following variables:

shell_escape = f
openout_any = p
openin_any = p

• as root, run:

# ./wikitex-audit.sh

until you get rid of all errors

• extensions/wikitex/wikitex-decruft.sh must be readable by <apache-user> since this account is used to run the decruft script via the cron job (wikitex.cron)
