FeministWiki:Server setup

!!! WORK IN PROGRESS !!!

These are the steps required to set up a new FeministWiki Debian server.

Update & upgrade

First of all, let's make sure the system is up to date.

 apt-get update
 apt-get upgrade
 apt-get dist-upgrade

Install miscellaneous tools

Some of these are needed further down, some are just good to have.

 apt-get install certbot
 apt-get install dnsutils
 apt-get install git
 apt-get install mg
 apt-get install moreutils
 apt-get install net-tools
 apt-get install nmap
 apt-get install software-properties-common
 apt-get install tree

Set up firewall

For now, block everything but SSH.

 apt-get install ufw
 ufw allow proto tcp to 0.0.0.0/0 port 22
 ufw enable

Install server components

We will now install all the software used for the various FeministWiki services. But first we might want to add some additional package repositories so we can use the latest version of some of the used software.

Backports:

 echo deb http://deb.debian.org/debian $(lsb_release -sc)-backports main > /etc/apt/sources.list.d/backports.list

PHP repo only if a very new version is needed:

 wget -O /etc/apt/trusted.gpg.d/sury-php.gpg https://packages.sury.org/php/apt.gpg
 echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/sury-php.list

MariaDB repo only if a very new version is needed:

 wget https://mariadb.org/mariadb_release_signing_key.asc
 apt-key add mariadb_release_signing_key.asc
 rm mariadb_release_signing_key.asc
 echo "deb http://mirror.23media.de/mariadb/repo/10.4/debian $(lsb_release -sc) main" > /etc/apt/sources.list.d/mariadb.list

Now we can install everything:

 apt-get install apache2
 apt-get install dovecot-core
 apt-get install ejabberd # good candidate for backports
 apt-get install fail2ban
 apt-get install mariadb-server
 apt-get install opendkim
 apt-get install php7.4 # or whatever version we're on
 apt-get install postfix
 apt-get install slapd

Example for installing ejabberd from backports instead:

 apt-get install ejabberd/$(lsb_release -sc)-backports

Fetch scripts & config repo

Set up GitHub ssh access by copying the .ssh/id_rsa from the old server. After that:

 cd ~
 git clone git@github.com:FeministWiki/FeministWiki.git repo
 cp -a repo/root/* .
 openssl aes-256-cbc -d -md sha512 -pbkdf2 -iter 100000 -in repo/pwd.enc -out - | tar -xzf-

The openssl decryption command will prompt you for a password. Enter the password stored in /root/pwd/meta on the old server.

Put config files in place

TODO

Create vmail user

 groupadd -g 5000 vmail
 useradd -u 5000 -g vmail -s /usr/sbin/nologin -d /home/vmail -m vmail

Stop services on old server

At this point, all services on the old server should be stopped, because we will now begin to transfer all the actual data.

Copy over LDAP databases

TODO

Copy over SQL databases

TODO

Copy over /var/www

TODO

Open ports

We are finally ready to serve:

 for port in 25 80 443 465 587 993 995 5222 5223 5269 5270 5443 6697 7777
 do ufw allow proto tcp to 0.0.0.0/0 port $port
 done

Reboot

We could restart a lot of services manually, but it's easiest to just reboot.

 reboot

Update DNS entries
