Create and serve multiple Shaarlis (farm)

Example bash script (creates multiple shaarli instances and generates an HTML index of them)

#!/bin/bash
set -o errexit
set -o nounset

#config
shaarli_base_dir='/var/www/shaarli'
accounts='bob john whatever username'
shaarli_repo_url='https://github.com/shaarli/Shaarli'
ref="master"

#clone multiple shaarli instances
if [ ! -d "$shaarli_base_dir" ]; then mkdir "$shaarli_base_dir"; fi

for account in $accounts; do
    if [ -d "$shaarli_base_dir/$account" ];
    then echo "[info] account $account already exists, skipping";
    else echo "[info] creating new account $account ..."; git clone --quiet "$shaarli_repo_url" -b "$ref" "$shaarli_base_dir/$account"; fi
done

#generate html index of shaarlis
htmlhead='<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<!-- Minimal html template thanks to http://www.sitepoint.com/a-minimal-html-document/ -->

    </head>
    <body>
    <div>
    <h1>My Shaarli farm</h1>
    <ul style="list-style-type: none;">'

accountlinks=''

htmlfooter='
    </ul>
    </div>
    </body>
</html>'    



for account in $accounts; do accountlinks="$accountlinks\n<li><a href=\"$account\">$account</a></li>"; done
if [ -d "$shaarli_base_dir/index.html" ]; then echo "[removing old index.html]"; rm "$shaarli_base_dir/index.html" ]; fi
echo "[info] generating new index of shaarlis"
echo -e "$htmlhead $accountlinks $htmlfooter" > "$shaarli_base_dir/index.html"
echo '[info] done.'
echo "[info] list of accounts: $accounts"
echo "[info] contents of $shaarli_base_dir:"
tree -a -L 1 "$shaarli_base_dir"

This script just serves as an example. More precise or complex (applying custom configuration, etc) automation is possible using configuration management software like Ansible
