Debian 6 shared
This guide is intended to systems where can be more than one DAViCal installation, and permissions are not open to other users in the system or in Apache websites.
Systems tested:
- Ubuntu 10.04
- Debian 6
Software versions tested:
- DAViCal 1.1.1
- PostgreSql 8.4
Install guide
Register stable repository (useful for any Ubuntu/Debian), and install DAViCal + PostgreSql service:
sudo apt-key advanced --keyserver pgp.net.nz --recv-keys F6E0FA5CF0307507BB23A512EAFCFEBF8FEB8EBF echo "deb http://debian.mcmillan.net.nz/debian stable awm #DAViCal CalDAV Server" | sudo tee /etc/apt/sources.list.d/davical.list sudo apt-get update sudo apt-get install postgresql davical davical-doc php5-curl
Prepare the DAViCal database values
DatabaseName=mycaldb DBUsername_dba=mycaluser_dba DBUsername_app=mycaluser_app DBPassword=12345 AdminPassword=1234
Add open permissions temporarily for the installation scripts:
MediumPgVersion="$(psql --version | grep -ie "sql" | tr -s " " "\n" | tail --lines=1 | cut -f 1,2 -d ".")" PgConfig="/etc/postgresql/${MediumPgVersion}/main/pg_hba.conf" sudo mv "$PgConfig" "${PgConfig}.davical-bak" sudo cp -a "${PgConfig}.davical-bak" "$PgConfig" echo "# Permissions for the DAViCal CMS" | sudo tee "$PgConfig" echo "local $DatabaseName $DBUsername_dba trust" | sudo tee --append "$PgConfig" echo "local $DatabaseName $DBUsername_app trust" | sudo tee --append "$PgConfig" echo "" | sudo tee --append "$PgConfig" sudo cat "${PgConfig}.davical-bak" | sudo tee --append "$PgConfig" sudo service postgresql-${MediumPgVersion} reload
Apply a temporary patch to creation script:
CScript="/usr/share/davical/dba/create-database.sh" sudo mv "$CScript" "${CScript}.davical-bak" sudo cp -a "${CScript}.davical-bak" "$CScript" cat "${CScript}.davical-bak" | sed -e "s/DBNAME=.*/DBNAME=${DatabaseName}/g" | sed -e "s/AWL_DBAUSER=.*/AWL_DBAUSER=${DBUsername_dba}/g" | sed -e "s/AWL_APPUSER=.*/AWL_APPUSER=${DBUsername_app}/g" | sudo tee "$CScript"
Apply a temporary patch to update script:
UScript="/usr/share/davical/dba/update-davical-database" sudo mv "$UScript" "${UScript}.davical-bak" sudo cp -a "${UScript}.davical-bak" "$UScript" cat "${UScript}.davical-bak" | sed -e "s/\$dbname = .*/\$dbname = \"${DatabaseName}\";/g" | sed -e "s/\$dbuser = .*/\$dbuser = \"${DBUsername_dba}\";/g" | sed -e "s/\$appuser = .*/\$appuser = \"${DBUsername_app}\";/g" | sed -e "s/\$dbpass = .*/\$dbpass = \"${DBPassword}\";/g" | sudo tee "$UScript"
(only fresh install) Run main installation script and take note of the shown password for the 'admin' user:
sudo su postgres -c "$CScript" "$DatabaseName" "$AdminPassword"
(only restoration of a backup) Restore data and run update script:
echo "DROP DATABASE IF EXISTS mycaldb;" | sudo su postgres -c psql echo "DROP USER IF EXISTS mycaluser_dba;" | sudo su postgres -c psql sudo su postgres -c "psql --quiet --file mycaluser_dba.pgdump" echo "DROP USER IF EXISTS mycaluser_app;" | sudo su postgres -c psql sudo su postgres -c "psql --quiet --file mycaluser_app.pgdump" sudo su postgres -c "psql --quiet --file mycaldb.pgdump" sudo su postgres -c "$UScript"
Restore installation scripts to original:
sudo mv "${UScript}.davical-bak" "$UScript" sudo mv "${CScript}.davical-bak" "$CScript"
(only fresh install) Set password authentication for the database:
echo "ALTER USER $DBUsername_dba WITH PASSWORD '${DBPassword}';" | sudo su postgres -c psql echo "ALTER USER $DBUsername_app WITH PASSWORD '${DBPassword}';" | sudo su postgres -c psql
Allow these authenticated access to PostgreSql:
echo "# Permissions for the DAViCal CMS" | sudo tee "$PgConfig" echo "local $DatabaseName $DBUsername_dba password" | sudo tee --append "$PgConfig" echo "local $DatabaseName $DBUsername_app password" | sudo tee --append "$PgConfig" echo "" | sudo tee --append "$PgConfig" sudo cat "${PgConfig}.davical-bak" | sudo tee --append "$PgConfig" sudo service postgresql-${MediumPgVersion} reload
Create or restore configuration file as /etc/davical/caldav.example.net-conf.php (for a virtualhost caldav.example.net) with its content as in the following example:
<?php $c->admin_email = 'admin@example.net'; $c->system_name = "My CalDAV Server"; $c->enable_row_linking = true; $c->default_locale = 'en_US.UTF-8'; $c->pg_connect[] = 'dbname=mycaldb port=5432 user=mycaluser_app password=12345';
Create or restore Apache virtualhost with its profile content as in this example:
<VirtualHost *:80> ServerName caldav.example.net DocumentRoot /usr/share/davical/htdocs DirectoryIndex index.php index.html Alias /images/ /usr/share/davical/htdocs/images/ <Directory /usr/share/davical/htdocs/> AllowOverride None Order allow,deny Allow from all </Directory> php_value include_path /usr/share/awl/inc php_value magic_quotes_gpc 0 php_value magic_quotes_runtime 0 php_value register_globals 0 php_value error_reporting "E_ALL & ~E_NOTICE" php_value default_charset "utf-8" </VirtualHost>
Enable Apache website:
sudo a2ensite caldav.example.net
Login to DAViCAL Admin
If all is going well you should now be able to browse to the site pages and log in as 'admin' with the password set during installation.
Backup all data
- Database (example for accessing mycaldb with user "mycaluser" and password "12345")
env PGPASSWORD=12345 pg_dump --create --inserts --attribute-inserts --disable-dollar-quoting --username=mycaluser -f "mycaldb.pgdump" mycaldb
- PostgreSql users/roles (example for mycaluser_dba + mycaluser_app)
cat /dev/null > mycaluser_dba.pgdump sudo su postgres -c "pg_dumpall --roles-only" | grep -e " ROLE mycaluser_dba;" >> mycaluser_dba.pgdump sudo su postgres -c "pg_dumpall --roles-only" | grep -e " ROLE mycaluser_dba " >> mycaluser_dba.pgdump cat /dev/null > mycaluser_app.pgdump sudo su postgres -c "pg_dumpall --roles-only" | grep -e " ROLE mycaluser_app;" >> mycaluser_app.pgdump sudo su postgres -c "pg_dumpall --roles-only" | grep -e " ROLE mycaluser_app " >> mycaluser_app.pgdump
- CMS configuration:
/etc/davical/caldav.example.net-conf.php
- Apache site profile:
/etc/apache2/sites-available/caldav.example.net
Additional tips
Reset the admin password
Useful after an installation, when we want to be sure of our wanted password (example for database name "mycaldb" and password "1234")
echo "UPDATE usr SET password = '**1234' WHERE user_no=1;" | sudo su postgres -c "psql --dbname mycaldb"
