Poddery - Diaspora, Matrix and XMPP
We run a diaspora service at poddery.com
Environment
We use diaspora-installer-mysql package from https://people.debian.org/~praveen/diaspora-jessie/
See /usr/share/doc/diaspora-common/README for package specific configuration.
System health check:
- There should be a data disk attached (added from cloud.scaleway.com)
- The attached disk (/dev/nbd2) should be an lvm physical volume (pvcreate /dev/nbd2). We cannot use it directly for encryption, so we use lvm.
- /dev/data is an lvm volume group created from /dev/nbd2 (vgcreate data /dev/nbd2).
- /dev/data/diaspora is an lvm logical volume (lvcreate -n diaspora /dev/data -L 93.5G).
- /dev/mapper/diaspora is an encrypted device (cryptsetup luksFormat /dev/data/diaspora; cryptsetup luksOpen /dev/data/diaspora diaspora)
- /dev/mapper/diaspora is an ext4 file system (mkfs.ext4 /dev/mapper/diaspora)
- /var/lib/diaspora should be mounted (mount /dev/mapper/diaspora /var/lib/diaspora)
- all critical data should be on /var/lib/diaspora.
- /etc/init.d/mysql stop; mv /var/lib/mysql /var/lib/diaspora; ln /var/lib/diaspora/mysql /var/lib/diaspora
- mkdir /var/lib/diaspora/uploads; chown -R diaspora: /var/lib/diaspora/uploads;ln -s /var/lib/diaspora/uploads /usr/share/diaspora/public/uploads

- loomio group - we use this for decision making.
- We also have a LibreSignal group for quick collaboration.
- Some of us also hangout at XMPP room of fosscommunity.in, #fci@conference.diasp.in

Setting up Backup
Backup is setup on a Scaleway C1 VPS (4 core ARM processor with 2GB RAM)
Hostname (IP): backup.poddery.com (212.47.244.122)
# apt-get install lvm2 cryptsetup
Directly creating luks volume on /dev/nbd1 is not working, so we use a logical volume
# pvcreate /dev/nbd1 # vgcreate data /dev/nbd1 # lvcreate -n diaspora -L 46.5G /dev/data
# cryptsetup luksFormat /dev/data/diaspora # cryptsetup luksOpen /dev/data/diaspora diaspora
and update /etc/crypttab
# <target name> <source device> <key file> <options> diaspora /dev/data/diaspora none luks
# mkfs.ext4 /dev/mapper/diaspora # mkdir /var/lib/diaspora
and update /etc/fstab
# UNCONFIGURED FSTAB FOR BASE SYSTEM /dev/mapper/diaspora /var/lib/diaspora ext4 defaults 0 2
# mount -a # apt-get install mysql-server
Move mysql data directory to encrypted volume
# /etc/init.d/mysql stop # mv /var/lib/mysql /var/lib/diaspora/ # ln -s /var/lib/diaspora/mysql /var/lib/mysql

# adduser sshtunnel --disabled-login # su sshtunnel
Generate ssh key pair and copy public key to target system
$ ssh-keygen -t rsa $ ssh -f sshtunnel@poddery.com -L 7777:127.0.0.1:3306 -N
Test the connectivity
# mysql -u poddery_backup -p -P 7777 -h 127.0.0.1
Uploads are rsynced every hour

1. Prosody error - Failed to load private key
certmanager error SSL/TLS: Failed to load '/etc/letsencrypt/live/poddery.com/privkey.pem': Previous error (see logs), or other system error. (for poddery.com) tls error Unable to initialize TLS: error loading private key (system lib) certmanager error SSL/TLS: Failed to load '/etc/letsencrypt/live/poddery.com/privkey.pem': Check that the permissions allow Prosody to read this file.
This error is usually when ssl certificate in freshly installed or renewed. Prosody user is unable to access the key file due to lack of privileges.
Note that Poddery uses Letsencrypt for ssl.
Fix:
- Make sure that prosody user is in 'certs' group (this group may also be called ssl-certs as setup by Letencrypt)
- /etc/letsencrypt/ is the ssl directory.
- Prosody user should have permissions to all folders importantly archive and live folders in /etc/letsencrypt. Permissions to each folder must be 750.
- Troubleshoot by checking if you can switch to each folder in /etc/letsencrypt as prosody user and cat the files.
