SYSTEM INSTALL INSTRUCTIONS
===========================
EOF

cat << EOF >> $OUTPUT

STEP 1
======

Set permissions on various files and directories. This must be run as root.

-------- BEGIN SCRIPT -------

install -d @prefix@/var/log/dsnpd
install -d @prefix@/etc/dsnpd-ssl
chown root:root @sysconfdir@/dsnpd.conf
chown root:root @sysconfdir@/dsnpd-ssl
chmod 600 @sysconfdir@/dsnpd.conf
chmod 700 @sysconfdir@/dsnpd-ssl
chown root:root @prefix@/var/log/dsnpd
chmod 700 @prefix@/var/log/dsnpd

-------- END SCRIPT -------
EOF

cat << EOF >> $OUTPUT

STEP 2
======

Install a logrotate fragment.

   @prefix@/var/log/dsnp/dsnpd.log
   @prefix@/var/log/dsnp/dsnpk.log
   @prefix@/var/log/dsnp/dsnpn.log
   {
       weekly
       missingok
       rotate 26
       compress
       delaycompress
       notifempty
       create 600 root root
       sharedscripts
       postrotate
           if test -f @PID_DIR@/dsnpd.pid; then
               kill -HUP "\`cat @PID_DIR@/dsnpd.pid\`"
	   fi
       endscript
   }
EOF

cat << EOF >> $OUTPUT

STEP 3
======

Install the init script from the share directory. The manner of installing this
will be system dependent.

#
# dsnpd.conf file.
#

cat << EOF >> $OUTPUT

STEP 4
======

Complete the following fragment by setting the notification script and add it
to $DSNPD_CONF

-------- BEGIN FRAGMENT --------

#
# Daemon
#
CFG_PORT = $CFG_PORT
CFG_DB_HOST = localhost
CFG_DB_USER = dsnpd
CFG_DB_DATABASE = dsnpd
CFG_DB_PASS = $CFG_DB_PASS1

#
# Key Agent.
#
CFG_KEYS_HOST = localhost
CFG_KEYS_USER = dsnpk
CFG_KEYS_DATABASE = dsnpk
CFG_KEYS_PASS = $CFG_DB_PASS2

#
# Notification Agent.
#
CFG_NOTIF_HOST = localhost
CFG_NOTIF_KEYS_USER = dsnpn
CFG_NOTIF_DATABASE = dsnpn
CFG_NOTIF_PASS = $CFG_DB_PASS3

-------- END FRAGMENT --------
EOF


#
# Database initialization
#

cat << EOF >> $OUTPUT

STEP 5
======

Initialize the database. This step will require the mysql root password. You
may wish to consider copying this fragment to a file and executing it to avoid
putting the database user and pass on your history.

-------- BEGIN SCRIPT -------

mysql -u root -p -B -N -e "
	CREATE USER 'dsnpd'@'localhost' IDENTIFIED BY '$CFG_DB_PASS1';
	CREATE DATABASE dsnpd;
	GRANT ALL ON dsnpd.* TO 'dsnpd'@'localhost';

	CREATE USER 'dsnpk'@'localhost' IDENTIFIED BY '$CFG_DB_PASS2';
	CREATE DATABASE dsnpk;
	GRANT ALL ON dsnpk.* TO 'dsnpk'@'localhost';

	CREATE USER 'dsnpn'@'localhost' IDENTIFIED BY '$CFG_DB_PASS3';
	CREATE DATABASE dsnpn;
	GRANT ALL ON dsnpn.* TO 'dsnpn'@'localhost';

	USE dsnpd;
	SOURCE ${DATADIR}/dsnpd/dsnpd.sql;

	USE dsnpk;
	SOURCE ${DATADIR}/dsnpd/dsnpk.sql

	USE dsnpn;
	SOURCE ${DATADIR}/dsnpd/dsnpn.sql
