This guide is very similar to my 'installing from source' post, but installing from CPAN makes more sence, since updates are issued there - making it much easier to upgrade using CPANs 'install MogileFS::Server' directly
In a perfect world, it should to just issue:
cpan
install MogileFS::Server
But version 2.34 is still imperfect..
On a clean Ubuntu install, start off by getting compilers etc.:
sudo apt-get install build-essential
Enter cpan, and install the following BEFORE mogilefs
cpan
install IO::AIO BSD::Resource
In that process the optimal would be to install DBD::mysql also - but that one failed for me, so go install the package from ubuntu repository instead:
sudo apt-get install libdbd-mysql-perl
Now you're ready to run the actual install command without it failing on you:
cpan
install MogileFS::Server
If you want additional features, you can install MogileFS::Client and MogileFS::Utils also
Now you have your mogstored and mogilefsd in
/usr/local/bin/mogilefsd, but that's pretty much all you have. For them to be useful you would need config files:
Here's mine from
/etc/mogilefs/mogilefsd.conf :
db_dsn = DBI:mysql:mogilefs:host=server1.example.com;port=3306;mysql_connect_timeout=10;mysql_ssl=1;mysql_compression=1
db_user = mog_user
db_pass = mog_pass
listen = 0.0.0.0:7001
node_timeout = 5
conf_port = 7001
listener_jobs = 10
delete_jobs = 1
replicate_jobs = 10
mog_root = /mnt/mogilefs
reaper_jobs = 1
rebalance_ignore_missing = 1
and from
/etc/mogilefs/mogstored.conf :
maxconns = 10000
httplisten = 0.0.0.0:7500
mgmtlisten = 0.0.0.0:7501
docroot = /var/mogdata
Create users you want mogilefsd and mogstored to run under:
sudo adduser mogilefsd
sudo adduser mogstored
My init.d script is under /etc/init.d/mogilefsd and modified from an older init script found in a custom repository:
