FeministWiki:Server setup

    From FeministWiki

    !!! 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 emacs
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

    The principle is simple: take all the config files from /root/repo/etc and put them where they belong in /etc. However, since a new server might mean much newer software, it's possible that some config files aren't compatible anymore. Sadly figuring out these incompatibilities is a manual process and this guide cannot help you much.

    There's one special thing to remember, which is that after copying in the new /etc/aliases file, you have to run the newaliases command for the changes to take effect.

    Create vmail user

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

    Initialize LetsEncrypt

    The first run of Certbot has to be interactive, so we will do that now. Since the DNS entries still point to the old server, we can't get a cert for the real domains. For now, make feministwiki.dev point to the IP address of the new server, then proceed with the commands below. 

    systemctl stop apache2
certbot certonly --cert-name feministwiki.org  # Yes, it should be .org and not .dev

    Then follow the on-screen instructions of certbot. Use the "standalone" authentication method when asked, and enter feministwiki.dev as the sole domain.

    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

    At this point you might want to do some testing with the feministwiki.dev domain.

    Reboot

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

    reboot

    Update DNS entries

    You have to change the configuration of the following domains:

    • feministwiki.org
    • feministwiki.net
    • feministwiki.de
    • fem.wiki
    • fffrauen.de

    feministwiki.org

    You only have to change three DNS entries, since most of the subdomains work via CNAME entries:

    • The main A entry for @ (self-reference i.e. feministwiki.org)
    • The A entry for smtp since this is not allowed to be a CNAME
    • The A entry for xmpp since this is not allowed to be a CNAME

    feministwiki.net, feministwiki.de, fem.wiki, fffrauen.de

    For these, you only have to change the main A entry, since they don't use SMTP or XMPP.

    Update the certificate

    Run the letsencrypt-refresh script to get a new certificate which includes all our domain names, since we had started out with just feministwiki.dev.
