Now I’ve got this working to some extent here are some notes about setting up Jekyll with SVN and Apache:
Server – Debian 9 Stretch, normal command-line only install. Set up system to use email server (campus smarthost in our case).
Install SVN and Apache and set up accordingly.
apt install jekyll
Create an SVN repository for the site files.
Create new project directories at a temporary location, e.g.
jekyll new /tmp/newsite
Commit these files to the SVN repository (I normally check out the repository on my local workstation, copy the directory in
/tmp from the server into the working directory on the workstation, add them and commit). Delete the directory in
On the server, create the actual website file location by exporting from the SVN via a temporary location:
svn export file:///path/to/repository /tmp/buildfiles jekyll build --source /tmp/buildfiles /var/www/sitename rm -Rf /tmp/buildfiles
Configure Apache to serve from
/var/www/sitename. In our case we ultimately wanted to serve multiple sites through a reverse proxy, so we used a vhost serving on an alternate port. This can be a handy testing configuration – you don’t have to worry about fiddling with the other website settings. For example, using port 8081:
<VirtualHost *:8081> ServerAdmin webmaster@localhost DocumentRoot /var/www/sitename </VirtualHost>
(Remember to change
ports.conf to listen on the new port!)
Test by pointing a webserver at server:8081
Once that’s all working, set up the post-commit hook script to automatically build the site on a commit. Our current setup is:
#!/bin/sh # POST-COMMIT HOOK REPOS="$1" REV="$2" REPOS_BASENAME=$(/usr/bin/basename "$REPOS") TMP_SVN_EXPORT="/tmp/$REPOS_BASENAME" # These two need configured! PUBLIC_WWW="/var/www/sitename" BUILD_EMAIL="email@example.com" "$REPOS"/hooks/mailer.py commit "$REPOS" $REV "$REPOS"/hooks/mailer.conf LOGVAR=$(/export0/svn_config/jekyll_build.sh "$REPOS" $REV "$TMP_SVN_EXPORT" "$PUBLIC_WWW" 2>&1) echo "$LOGVAR" | /usr/bin/unix2dos | mail -s "$REPOS_BASENAME build $REV" "$BUILD_EMAIL"
(Note that on Debian you need to install the
dos2unix package. Needed as plain text email expects CRLF line terminators as specified in RFC 2822.)
#!/bin/sh REPOS="$1" REV="$2" TMP_SVN_EXPORT="$3" PUBLIC_WWW="$4" /usr/bin/svn export --quiet file:///"$REPOS" "$TMP_SVN_EXPORT" /usr/bin/jekyll build --source "$TMP_SVN_EXPORT" --destination "$PUBLIC_WWW" rm -Rf "$TMP_SVN_EXPORT"
Note that the build process runs under the Apache user account, so set permissions appropriately. Also, when troubleshooting remember that on Debian 9 the Apache process is configured by default to use a private /tmp directory!
This works for our current needs, although it isn’t optimised. Improvements would be:
- Unify the setup for the commit email and build email scripts.
- Build the site in the background (although you’d have to tweak how the logging output works in that case).
Of course, the professionals would use something like a combination of GitLab and Jenkins to automate this stuff properly…
