MirrorBrain – Download Redirector and generates Metalinks, Torrents and crypto-hashes
Sponsored Link
A central (and probably the most obvious) part is a "download redirector" which automatically redirects requests from web browsers or download programs to a mirror server near them.
Choosing a suitable mirror for a users request is the key, and MirrorBrain uses geolocation and global routing data to make a sensible choice, and achieve load-balancing for the mirrors at the same time. The used algorithm is both sophisticated and easy to control and tune. In addition, MirrorBrain monitors mirrors, scans them for files, generates mirror lists, and more.
Install mirror brain in ubuntu
First you need to make sure you have install Ubuntu LAMP server once you have this you need to Add package repository
edit /etc/apt/sources.list file
sudo vi /etc/apt/sources.list
Add one of the following
For ubuntu 10.04 users add the following line
deb http://download.opensuse.org/repositories/Apache:/MirrorBrain/Ubuntu_10.04/ /
For ubuntu 9.10 users add the following line
deb http://download.opensuse.org/repositories/Apache:/MirrorBrain/xUbuntu_9.10/ /
Save and exit the file
Install GPG key
sudo apt-key adv --keyserver hkp://wwwkeys.de.pgp.net --recv-keys BD6D129A
Update source list
sudo apt-get update
Install the MirrorBrain packages using the following command
sudo apt-get install mirrorbrain mirrorbrain-tools mirrorbrain-scanner libapache2-mod-mirrorbrain libapache2-mod-autoindex-mb
install an Apache MPM
sudo apt-get install apache2-mpm-worker
Note :- If the LAMP server has been installed, the prefork MPM was probably preselected. It may make sense to switch to the worker MPM in such cases, which is a good choice for busy download servers. If something like PHP is in use as embedded interpreter (mod_php), though, then you need to stick to the prefork MPM, because libraries that are used by PHP might not be threadsafe.
Configure mod_geoip
mod_geoip is configured to look for the GeoIP data set in /var/lib/GeoIP. You need to download the GeoIP data set. We chose the larger “city” dataset:
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
gunzip GeoIP.dat.gz
sudo mkdir /var/lib/GeoIP
sudo cp GeoIP.dat /var/lib/GeoIP/GeoIP.dat
Configure mod_dbd
With Ubuntu 10.04, the DBD (Apache Portable Runtime DBD Framework) database adapter for PostgreSQL is already installed, because the driver is statically linked into the libaprutil1 shared object. libaprutil1-dbd-pgsql is a virtual package which is just a pointer to the libaprutil1 package.
Running the following snippet will create a configuration for mod_dbd:
sudo sh -c "cat > /etc/apache2/mods-available/dbd.conf << EOF
<IfModule mod_dbd.c>
DBDriver pgsql
DBDParams ‘host=localhost user=mirrorbrain password=12345 dbname=mirrorbrain connect_timeout=15'
</IfModule>
EOF
"
Note:-Edit the password in the template here – take note of it, you’ll need it below, when you create a database user account.
Install PostgreSQL
Install the PostgreSQL server (here, version 8.4 is the current version):
sudo apt-get install postgresql-8.4
Create the postgresql user account and database
Switch to user postgres:
sudo su -- postgres
Create user:
createuser -P mirrorbrain
Enter password for new role:
Enter it again:
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) n
Shall the new role be allowed to create more new roles? (y/n) n
Create database:
createdb -O mirrorbrain mirrorbrain
createlang plpgsql mirrorbrain
Exit user postgres:
exit
Edit host-based authentication
Add line host mirrorbrain mirrorbrain 127.0.0.1/32 md5 to the end of pg_hba.conf, which is to be found here:
sudo vim /etc/postgresql/8.4/main/pg_hba.conf
Start the PostgreSQL server:
sudo /etc/init.d/postgresql-8.4 restart
Create needed users and groups
Create user and group mirrorbrain:
sudo groupadd -r mirrorbrain
sudo useradd -r -m -g mirrorbrain -s /bin/bash -c "MirrorBrain user" -d /home/mirrorbrain mirrorbrain
Import initial mirrorbrain data
Import structure and data, running the commands as user mirrorbrain:
sudo su -- mirrorbrain
gunzip -c /usr/share/doc/mirrorbrain/sql/schema-postgresql.sql.gz | psql -U mirrorbrain mirrorbrain
gunzip -c /usr/share/doc/mirrorbrain/sql/initialdata-postgresql.sql.gz | psql -U mirrorbrain mirrorbrain
exit
Create needed directories
Create the following directory for logs, and give ownership to the new mirrorbrain user:
sudo mkdir /var/log/mirrorbrain
sudo chown mirrorbrain:mirrorbrain /var/log/mirrorbrain
sudo chmod 0750 /var/log/mirrorbrain
Once this installation completed you need to follow mirrorbrain configuration steps
