New Fasthosts VPS
=================

New virtual private server for email and seme4.com website

Fasthosts.co.uk "VPS2" (2 cores, 4GB RAM, 120GB NVMe SSD). Debian 12

``87.106.35.187``

"Cloud Panel" at https://cloud.admin.fasthosts.co.uk/  (username ian.millard@seme4.com)


Initial setup
-------------

Login as root with password from control panel.


Hostname
~~~~~~~~

.. code:: console

  [root@seme4]#  hostname seme4.com

edit ``/etc/hostname`` to contain ``seme4.com``

IPv6
~~~~

Allocated new address via web control panel

.. code:: console

  [root@seme4]#  ip address add 2a00:da00:f423:dd00::1 dev ens6

Create users
~~~~~~~~~~~~

.. code:: console

  [root@seme4]#  useradd -m -g users -G staff,sudo -s /bin/bash icm
  [root@seme4]#  useradd -m -g users -G staff,sudo -s /bin/bash hg
  [root@seme4]#  passwd icm
  [root@seme4]#  passwd hg

Install sympl
~~~~~~~~~~~~~

https://sympl.io is an open source fork/extension of the old Bytemark symbiosis hosting utilities.

.. code:: console

  [root@seme4]#  wget -O install-sympl.sh https://gitlab.com/sympl.io/install/-/raw/master/install.sh
  [root@seme4]#  bash install-sympl.sh


General administration
----------------------

Note that operations should be undertaken as the ``sympl`` user  (run ``sudo su -l sympl``)

**Do not use** ``root``.

Websites, mail, config etc are defined and stored under ``/srv/seme4.com/`` and
should be configured and manipulated primarily using the ``sympl`` command line
tool.

See https://wiki.sympl.io/view/Sympl for more info (also possibly https://forum.sympl.io/)

Create website
~~~~~~~~~~~~~~

.. code:: console

  [sympl@seme4]$  sympl web create subdomain.seme4.com
  [sympl@seme4]$  touch /srv/subdomain.seme4.com/config/ssl-only
  [sympl@seme4]$  sudo sympl-web-configure

Create database
~~~~~~~~~~~~~~~

.. code:: console

  [sympl@seme4]$  sympl mysql create dbName

Note it actually uses MariaDB


Data transfer from old server
-----------------------------

Old: ``213.138.114.57``

New:  ``87.106.35.187``

On the old host, set a new temporary root password: nXzQK7MwuqHB3PTsCEtYrV

Also edit ``/etc/ssh/sshd_config`` and set ``PermitRootLogin`` to ``Yes``. Restart with ``sudo systemctl restart sshd``

On the new host stick the following into ``/home/sympl/.ssh/config``

.. code::

  Host 213.138.114.57
    User root
    HostKeyAlgorithms=+ssh-rsa,ssh-dss
    PubkeyAcceptedKeyTypes=+ssh-rsa,ssh-dss

And execute the following commands

.. code:: console

  [sympl@seme4]$  sudo chown sympl:root /home/sympl/.ssh
  [sympl@seme4]$  sudo chmod g+rw /home/sympl/.ssh
  [sympl@seme4]$  ssl-keygen
  [sympl@seme4]$  ssh-copy-id root@213.138.114.57

We can then ``rsync`` effectively from old to new using ssh keys (without password)

A couple of scripts have been written to perform migration

Website
~~~~~~~

``/home/sympl/server-migration/migrate-website.sh`` transfered the seme4.com wordpress website

.. code::console 

  [sympl@seme4]$  a2dissite zz-mass-hosting
  [sympl@seme4]$  a2dissite zz-mass-hosting.ssl
  [sympl@seme4]$  sudo systemctl reload apache2


Email
~~~~~

``/home/sympl/server-migration/migrate-email.sh`` brings across (all) email

Subversion
~~~~~~~~~~

Subversion needs to be run under apache, so sticking it on this server.

Fix DNS to point to this server

.. code:: console

  [sympl@seme4]$  sudo apt install subversion libapache2-mod-svn
  [sympl@seme4]$  sympl create web svn.seme4.com
  [sympl@seme4]$  sudo sympl-ssl --force svn.seme4.com
  [sympl@seme4]$  touch /srv/svn.seme4.com/config/ssl-only
  [sympl@seme4]$  sympl create web svn.ianmillard.com
  [sympl@seme4]$  sudo sympl-ssl --force svn.ianmillard.com
  [sympl@seme4]$  touch /srv/svn.ianmillard.com/config/ssl-only
  [sympl@seme4]$  sudo sympl-web-configure

``/home/sympl/server-migration/migrate-svn.sh`` brings across SVN data


After much frustration as to why javascript wasn't being served...

.. code:: console

  [sympl@seme4]$  sudo a2disconf javascript-common
  [sympl@seme4]$  sudo systemctl reload apache2
