Apply patches

/!\ WARNING, ONLY FOR OREON 1.4 /!\

Retrieve patches:

# mkdir oreon-1.4-patches
# cd oreon-1.4-patches
# (I=1; STATUS=0;
  while [ $STATUS -eq 0 ]; do
    wget http://download.oreon-project.org/patch/oreon-patch-1.4-$I.tgz;
    STATUS=$?;
    I=$(($I+1));
  done)

Note: This script has a small error since it will try to download oreon-patch-1.4-6.tgz as well

Unpack patches:

# (for TARGZ in *.tgz; do
     mkdir $TARGZ.unpack && tar -C $TARGZ.unpack -zxf $TARGZ;
   done)

Apply all the patches:

# (for UNPACK in *.unpack; do
     for PATCH in $UNPACK/*.patch $UNPACK/*/*.patch; do
       echo "Applying patch $PATCH";
       cat "$PATCH" | (cd /usr/local/oreon && patch -p1);
     done;
   done)

Web install

Restart apache/mysql

# /etc/init.d/mysql restart
# /etc/init.d/apache2 restart

and finalize the installation with the Oreon Web interface:

http://your_server/oreon/

Parameters:

 Nagios Version = [2.x]

 Oreon Database Name = [oreon]
 Oreon Data Storage Database Name = [ods]
 Oreon Database Password = [******]
 MySQL Client version (Password Haching Changes) = [>=4.1 - PASSWORD()]

 Administrator login for Oreon = [admin]
 Administrator password for Oreon = [******]
 Administrator Email for Oreon = [someone@somewhere]

Fix paths in Oreon database for Debian Nagios

Now we need to change some default parameters to follow the layout from Nagios:

# mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 18
Server version: 5.0.32-Debian_7etch1-log Debian etch distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
