SilverFile General Server Setup

Installation of Ubuntu 9.04 Server 32bit

We are selecting this version for the following reasons:

• GRUB installation doesn't work in older releases.
• 64 bit version does not seem to support the VIA padlock engine

Partitioning (During Install)

We feel that 20GB and 6GB of swap is more than sufficient, leaving ample room for client files.

• / 20GB Primary Ext3 Bootable = Yes (leave all other defaults)
• swap 6GB swap
• /FILES/ Primary Ext3 Bootable = No (leave all other defaults)

Install SSH Deamon

sudo apt-get install ssh openssh

Change SSH Port

edit /etc/ssh/sshd_config Change port line to 2222 (or whatever port) restart sshd to check

/etc/init.d/ssh restart

OpenSSL

Installation

sudo apt-get install openssl

Verification

Next, verify engine:

> openssl engine
(padlock) VIA PadLock (no-RNG, ACE)
(dynamic) Dynamic engine loading support

The response string should include '(padlock) VIA PadLock (no-RNG, ACE)'.

Make default engine Padlock

> vim /etc/ssl/openssl.cnf
...
oid_section             = new_oids

# Enable Via Padlock by default
openssl_conf = openssl_def

[openssl_def]
engines = openssl_engines

[openssl_engines]
padlock = padlock_engine

[padlock_engine]
default_algorithms = ALL

GnuPG / Duplicity

> sudo apt-get install duplicity python-boto

Install Apache for Django

​Great Ubuntu Apache/SSL How-To

> sudo apt-get install apache2 libapache2-mod-python
> sudo ln -s /usr/sbin/apache2ctl apachectl (old habits die hard)

Configure SSL

> sudo a2enmod ssl

copy cert file (mydomain.com.crt) to /etc/ssl/certs copy key file (mydomain.com.key) to /etc/ssl/private

Configure Apache for SilverFile App

Django app is turned "on" by default. Two locations (webspaces) are turned off, and are served directly. These are:

• site_media (css, js, images, etc...)
• site_files (these are all the client files)

Setting up a Software RAID 1 - (DEPRECATED)

We are using the hardware raid cards now, so this is deprecated.

Per recommendations from our friends at MonkeyBrains, we'll set up a software RAID 1 and monitor it with mdadm. The plan is to sync up RAID health with SNMP monitoring.

This is a very good tutorial on ​setting up a software RAID 1 please follow it for the step by step RAID install.

The idea is to create 3 partitions:

• / (root) where all the OS etc files go
• /FILES where all the documents go
• Swap The necessary swap partition

On a 500 GB drive I propose doing this :

• /FILES = 430 GB
• Swap = 4 GB (swap is conventionally 2X RAM, a swap this size may not be necessary with 2 GB of RAM and for use as a file server
• / = <leftover space>

In order to create the software RAID, you first create regular primary partitions on the first disk (SDA) as in the following:

select: Partition Disk Manually
select: Device SDA1
Create new empty partition table on this device: yes
Select Free Space (pri/log): <per size of the disk>
select: Create new primary partition
Mount point: /
Bootable Flag: on
Use as: Select Physical Volume For RAID
select: Done Setting up partition

And then you create an MD device from each partition.

Again, see the ​RAID tutorial as it explains exactly how to do this step by step.
