Getting 500 error after new install in localhost/~home dir. Have ExecCGI/mod_cgi, setuid exec and owner is apache user, apache is running.

Apache log doesn't say anything more than the html reply:

"Error message:
End of script output before headers: ikiwiki.cgi"



I have copied over the ikiwiki.setup file from /usr/share/doc/ikiwiki/ to /etc/ikiwiki/ and run it after editing. My site gets built but when I click on the 'edit' button, firefox and google chrome download the cgi file instead of creating a way to edit it. The permissions on my ikiwiki.cgi script look like this: -rwsr-sr-x  1 root root 13359 2009-10-13 19:21 ikiwiki.cgi. Is there something I should do, i.e. change permissions, so I can get it to run correctly? (jeremiah)

I just went through the standard procedure described for setup, copied the blog directory from examples into my source directory, ran ikiwiki, and everything seems to have worked, except that none of the 
[[!meta ... ]] tags get converted. They simply show up in the html files unformatted, with no exclamation point, and with p tags around them. Any ideas? using ikiwiki version 2.40 on freebsd --mjg

Can the instructions for using `ikiwiki-makerepo` be clarified. This
command wants to create folders in the directory it is run in. Which
directory should that be - `$SRCDIR?` --Andy

Sorry, was not precise enough. It does if you are using the git option. I
believe this is partially explained on the rcs/git/ page. However I'm still
not totally clear where I should run the command when using git. If I
should be in $SRCDIR then updating the instructions to something like

    REPOSITORY=~/wiki.git
    cd $SRCDIR
    ikiwiki-makerepo git $SCDIR $REPOSITORY

might clear things up a little. Apologies if I'm being a bit dim, learning
ikiwiki and git at same time :) 

Have tried 3 options

1. mkdir $REP cd $REP run command (says $REP already exists so won't run)
2. rm -rf $REP cd $SRC run command (creates a repository in $SRC, does not create $REP ends with "remote origin already exists"
3. mkdir $TMP cd $TMP run command (creates a repository in $SRC/.git creates a repository in $TMP, does nothing to $REP, ends with "remote origin already exists".

Version of ikiwiki installed is package from Ubuntu/Hardy 2.19
Git version is 1.5.2.5

n.b. svn version of command worked fine :)

Looks like your git does not support GIT_DIR being used with git-init. I
see some mentions of changes in git's changelog for 1.5.3 that look
relevant. I've changed ikiwiki-makerepo to use a method more portable to
older versions of git. --[[Joey]]

Many thanks Joey, upgraded my git, and now have working iki :) -- Andy

It isn't intended that .ikiwiki be versioned, is it? Do you have a svn:ignore set? 
Is there some magic way you can make the svn commands (and presumably commands for 
the other VCSs here) ignore the .ikiwiki directory during step 8, when they import it?
If not, maybe a note should be made that the user should delete this file before 
they import. --Ethan

These instructions should probably show how to use a bare Git repository
(`GIT_DIR=somewhere.git git-init-db`) rather than a repository with a full
working copy. You can always clone the repository if you want your own local
working copy. Furthermore, this allows you to make multiple commits to your
working copy before pushing them to the repository and causing the wiki to
update. --[[JoshTriplett]]

> I'm currently testing and running such a setup. --[[tschwinge]]

Furthermore the git instructions should be changed to move the *.ikiwiki*
directory back into the wiki's working copy directory, isn't it? --[[tschwinge]]

> Yes, I think so.  I will clean these instructions up unless somebody tells me we're missing something fundamental. --[[BartMassey]]

>> Either you do it or I'll do it somewhen soon.  --[[tschwinge]]

Curious as to why support for CVS is not built in. --[[Luther]]

What is the syntax for specifying the adminuser as an openid user?  I've tried a couple things but I'm missing something.   Thanks for any pointers.  -- [[AdamShand]]

----

I apologize if this is the incorrect forum for this question, but I am
trying to get ikiwiki set up and running with git.  I followed all the
directions and all seems to work until I go back and try to make changes.
The steps I am performing:

    cd $SRCDIR  (e.g. ~/ikisrc)
    vim index.mdwn (add a couple lines)
    git commit -a -m 'test'
    git push

I then get a long error message which reads in part "You asked me to pull
without telling me which branch you want to merge with, and
'branch.master.merge' in your configuration file does not tell me either."
From that point on, I get:

    sws@odin:~/dev/ikisrc$ git push
    To /home/git/repos/myikiwiki.git
     ! [rejected]        master -> master (non-fast forward)
    error: failed to push to '/home/git/repos/myikiwiki.git'

If I do a git clone ssh://odin/path/to/$REPOSITORY from another machine and
try to edit I get the same error sequence.  What am I doing wrong?

I follow every steps of the setup procedure, change some templates and
tried to modify some page through the web but was not able to do so. Every
page seems to be locked by the adminuser user. When I remove the adminuser
in the setup file, every ran fine. Did I miss something ? What is exactly
the adminuser supposed to be allowed to ? Is he the only user allowed to
modify pages ?

pI hope you guys can put up with an absolute newbie. I am fairly new to linux and completely new to Perl. I have just installed MoinMoin locally in my PC, running ubuntu 8.4 and was about to use it until I ran into your ikiwiki. I thought ikiwiki is a better fit for what I want to do, so am seriously considering installing it as well in ubuntu. Except that the install seems way beyond my understanding.

Do i need to install git first? Which git -- the git-core? Ubuntu's instructions on installing the git-core is: "sudo apt-get install git-core". Is that it? Do I need to do a git-init as well, or will the ikiwiki-makerepo handle that? If I have to do a git-init as well, what --share values should I specify?

It seems I will have to install the ikiwiki from the tar.gz file. I have downloaded it, but do I need to install CPAN or CPAN++ first? That doesn't sound right. I am totally confused already. Does anyone have some install documents pitched to someone as ignorant as I am? -- [[WillDioneda]]

Thanks for your response. You're right. Ubuntu does have ikiwiki, except that it is an older version. I tried installing it; saw some error messages from the install, and decided against it. Plus the documentation here in ikiwiki.info seems slightly different. I made an executive/beginner decision: to go for the latest tarball. And found myself in deep water, ...

Anyway, I think I might be able to install it from the tarball I downloaded. I've been reading the discussions, had a look at your screencasts, etc. I will give it another bash. -- [[WillDioneda]]

How do I set up cgi editing?  In setup I have:

 * cgiurl => 'http://wiki.had.co.nz/edit.cgi'
 * cgi_wrapper => 'edit.cgi'

But I don't get an edit link on my pages?  What am I doing wrong?

I setup ikiwiki on a fedora 10 machine and I am using apache as my http server. Faced a few difficulties while setting it up as the default setup program left some suid files and group writeable directories on the system. It took some time to get it working and documented what I did at http://flyingtux.blogspot.com/2009/03/installing-ikiwiki.html. Thought it might be useful to someone here. (The version installed is 2.72)

/etc/ikiwiki/auto.setup tries to get abs_path of a non-existent
"repository" path (in ikiwiki-makerepo), and that doesn't work in my perl:

<pre>
[mort@localhost ~]$ perl -e 'use Cwd q{abs_path}; print abs_path("/var")'
/var[mort@localhost ~]$ perl -e 'use Cwd q{abs_path}; print abs_path("/abcde")'
[mort@localhost ~]$ 
</pre>

Because of this, /etc/ikiwiki/auto.setup fails: 

<pre>
$ ikiwiki -setup /etc/ikiwiki/auto.setup
What will the wiki be named? wiki
What revision control system to use? git
What wiki user (or openid) will be admin? mort


Setting up wiki ...

Thank you! I'm not a Perl programmer, so what's your opinion: is this behavior a violation of the specification of abs_path and I should report it to [ALTLinux](http://bugs.altlinux.org) (the distro)? --Ivan Z.

I am experiencing the same problem "/etc/ikiwiki/custom: failed to set up the repository with ikiwiki-makerepo
" on Debian squeeze with perl5.10.0. Upgrading to ikiwiki 3.10 fixes it. -- [Albert](http://www.docunext.com/)

----

Just a note, perl 5.10 isn't packaged as part of RHEL or thus CentOS nor EPEL,
so it's not especially trivial to satisfy that requirement for ikiwiki on
those platforms, without backporting it from Fedora or building from source.
However, I have an ikiwiki 3.20100403 running on RHEL-4 supplied 5.8.8 without
(seemingly too much) complaint.  How strong is the 5.10 requirement? what
precicely breaks without it? -- [[Jon]]

Did anyone tried to install ikiwiki under a vhost setup ? 
ikiwiki is installed under a debian lenny system. but without write acces to /etc/ikiwiki (obvious) i am coming not far.
Or do i miss something which is probably hidden deeper in the documentation ?

Well it should be similar to shared hosting [or a remote server in general](http://ikiwiki.info/forum/how_to_setup_ikiwiki_on_a_remote_host/)

----
Perhaps it's worth noting that when installing ikiwiki with apt on Debian stable, you need to use the backports version in order to follow the setup instructions.

---
The mentioned docker image does not seem to be supported anymore. For those interested I've setup another docker image here on [[github|https://github.com/dgsb/docker-ikiwiki]] and here on [[docker hub|https://hub.docker.com/r/dgsb/ikiwiki/]]. It has the advantage of not being sandboxed and using a local repository through a volume to setup the content of the wiki. A ssh server is also started in order to push/pull to/from the container -- David
