The content is now fully covered and updated in *create-a-wiki-preview.mdwn* and *create-a-wiki/additional.mdwn*. Also move the dated *create-a-wiki.mdwn* -> *create-a-wiki/create-a-wiki.mdwn*.

The purpose of the experiment is to learn how Ikiwiki +functions and how to effectively work with Ikiwiki and offline editing +with git. + +The components needed are + + * Ikiwiki + * Apache2 or Nginx web server + * Git + +**Table of Contents** +[[!toc]] + +What I have in mind is to access my lab wiki through +`http://localhost/~/lab-wiki` for web editing and +`~/lab-wiki/wiki-slave` for local offline editing. + +It should be noted that what is described here probably is a perfectly +_unsafe_ usage of a web server. Make sure that the computer does not +except requests from Internet. + + +Install and configure Git +========================= + +I can not recall how this was done. Refer to +[Git's official website](https://git-scm.com/) + + +Install and configure Ikiwiki +============================= + +Refer to [ikiwiki setup](https://ikiwiki.info/setup/) at +[ikiwiki's official website](https://ikiwiki.info) for initial +install and configuration and +[an article on Git](https://ikiwiki.info/rcs/git/) for more details on +setting up Ikiwiki together with Git. + +Install packages referred to in the ansible configuration: + + sudo aptitude install \ + ikiwiki \ + libauthen-passphrase-perl \ + highlight-common libhighlight-perl libimage-magick-perl \ + libmail-sendmail-perl libnet-dns-sec-perl \ + fcgiwrap spawn-fcgi \ + pandoc + +I did my best to answer the questions provided in the initial +installation and default configuration with the target of ending up +with something like this: + + url: http://localhost/~/lab-wiki + srcdir: ~/lab-wiki/wiki + destdir: ~/public_html/lab-wiki + repository: ~/lab-wiki/wiki.git + settings: ~/lab-wiki/wiki.setup + +However, not all of the above was configurable in the form, for +example the configuration file location. I needed to move directories +and files around and change the remaining configurations in +`~/lab-wiki/wiki.setup` and run + + $ ikiwiki --setup ~/lab-wiki/wiki.setup + +I also created the extra Git repository `wiki-slave` for local edits: + + $ cd ~/lab-wiki; git clone wiki.git wiki-slave + +The connectivity chart is now as follows + + Bare Git Repository + ~/lab-wiki/wiki.git + / \ + / \ + / \ + The Ikiwiki Repository | + ~/lab-wiki/wiki | + | | + | Repository for Local Edits + | ~/lab-wiki/wiki-slave + | | + The Ikiwiki Web Part | + ~/public_html/lab-wiki | + | + The Preview Ikiwiki Web Part + ~/public_html/lab-wiki-preview + + +Install and configure Apache 2 +============================== + +For installation, follow the instructions in +[Apache's official documentation](https://httpd.apache.org/docs). I +got Apache 2.4.6 installed. + +I needed to activate the userdir module. Refer to +[Per-user web directories](https://httpd.apache.org/docs/2.4/howto/public_html.html) +in Apache's documentation. For Debian do the following + + $ cd /etc/apache2/mods-enabled + $ ln -s ln -s ../mods-available/userdir.load + $ ln -s ln -s ../mods-available/userdir.conf + +Also CGI execution need to be activated. See +[Dynamic Content with CGI](https://httpd.apache.org/docs/2.4/howto/cgi.html) +in Apache's documentation. My +`/etc/apache2/mods-available/userdir.conf` now looks as follows + + + UserDir public_html + UserDir /home/*/public_html + UserDir disabled root + + + AllowOverride FileInfo AuthConfig Limit Indexes + Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec + + Require all granted + + + Require all denied + + + + + Options +ExecCGI + AddHandler cgi-script .cgi + + + Options +ExecCGI + AddHandler cgi-script .cgi + + + + +Install and conifgure Nginx +=========================== + +A valid web server alternative +is +[Nginx](http://nginx.org/en/docs/). + +For installation and configuration +follow [Ikiwiki on Dot CGI](https://ikiwiki.info/tips/dot_cgi/). `sudo +aptitude install nginx`. Note the alexjj comment that on +Debian the package *fcgiwrap* automatically spwans the FastCGI +program. + + + +Get preview of local modifications +================================== + +Now every thing works as work as expected. I can fetch the latest +updated to `wiki-slave`, perform my updates, and whenever those are +pushed to `origin/master`, the post-update hook makes sure that the +web version is updated. + +But what if I want to inspect and verify my local changes before +pushing them to `origin/master`? + +The subject is covered in +[the article on Git](https://ikiwiki.info/rcs/git/). I did what +follows. Copy `wiki.setup` to `wiki-preview.setup` and edit those +fields: + + wikiname: lab-wiki-preview + srcdir: ~/lab-wiki/wiki-slave + destdir: ~/public_html/lab-wiki-preview + url: http://skolem/~/lab-wiki-preview + cgiurl: http://skolem/~/lab-wiki-preview/ikiwiki.cgi + cgi_wrapper: ~/public_html/lab-wiki-preview/ikiwiki.cgi + git_wrapper: ~/lab-wiki/wiki-slave/.git/hooks/post-commit + gitorigin_branch: '' + gitmaster_branch: master + +The idea is that the preview wiki works against `wiki-slave`, which is +my simulated environment for local repository. What always works now +is to, at any point, recompile/refresh the wiki: + + ikiwiki -setup ~/lab-wiki/wiki-preview.setup -refresh + +Also, committing on the local `master` branch _should_ automatically +update the `lab-wiki-preview` wiki. -- cgit v1.2.3
