General Information:
This is a setup for a Tor based shared hosting server. It is provided as is and before putting it into production you should make changes according to your needs. This is a work in progress and you should carefully check the commit history for changes before updating.
Installation Instructions:
The configuration was tested with a standard Debian bullseye and Ubuntu 20.04 LTS installation. It's recommended you install Debian bullseye (or newer) on your server, but with a little tweaking you may also get this working on other distributions and/or versions. If you want to build it on a raspberry pi, please do not use the raspbian images as several things will break. Download an image for your pi model from https://raspi.debian.net/daily-images/ instead.
Uninstall packages that may interfere with this setup:
DEBIAN_FRONTEND=noninteractive apt-get purge -y apache2* dnsmasq* eatmydata exim4* imagemagick-6-common mysql-client* mysql-server* nginx* libnginx-mod* php7* resolvconf && systemctl disable systemd-resolved.service && systemctl stop systemd-resolved.service
If you have problems resolving hostnames after this step, temporarily switch to a public nameserver like 1.1.1.1 (from CloudFlare) or 8.8.8.8 (from Google)
rm /etc/resolv.conf && echo "nameserver 1.1.1.1" > /etc/resolv.conf
Install git and clone this repository
apt-get update && apt-get install git && git clone https://github.com/DanWin/hosting && cd hosting
Install custom optimized binaries
./install_binaries.sh
To get the latest mariadb version, you should follow these instructions to add the official repository for your distribution: (https://downloads.mariadb.org/mariadb/repositories/)
Add torproject to our repositories:
curl --socks5-hostname 127.0.0.1:9050 -sSL http://apow7mjfryruh65chtdydfmqfpj5btws7nbocgtaovhvezgccyjazpqd.onion/torproject.org/A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc > /etc/apt/trusted.gpg.d/torproject.gpg
echo "deb tor://apow7mjfryruh65chtdydfmqfpj5btws7nbocgtaovhvezgccyjazpqd.onion/torproject.org/ `lsb_release -cs` main" >> /etc/apt/sources.list
apt-get update && apt-get upgrade
Note that debian also has an onion service package archive, so you may want to edit /etc/apt/sources.list to load from there instead:
deb tor://2s4yqjx5ul6okpp3f2gaunr2syex5jgbfpfvhxxbbjwnrsvbk5v3qbid.onion/debian `lsb_release -cs` main
Copy (and modify according to your needs) the site files in var/www to /var/www, usr/local to /usr/local and the configuration files in etc to /etc after installation has finished. Then restart some services:
systemctl daemon-reload && systemctl restart bind9.service && systemctl restart tor@default.service
Replace the default .onion domain with your domain:
sed -i "s/dhosting4xxoydyaivckq7tsmtgi4wfs3flpeyitekkmqwu4v4r46syd.onion/`cat /var/lib/tor/hidden_service/hostname`/g" /etc/postfix/sql/alias.cf /etc/postfix/sender_login_maps /etc/postfix/main.cf /var/www/skel/www/index.hosting.html /var/www/common.php /etc/postfix/canonical /etc/postfix-clearnet/canonical /var/www/html/squirrelmail/config/config.php
For your clearnet domain, you need to add it to relay_domains in /etc/postfix/main.cf and edit the default domain in the following files:
/var/www/common.php
/etc/postfix/canonical
/etc/postfix-clearnet/canonical
This setup has two postfix instances, one for receiving and sending mail to other .onion services and one for rewriting addresses to pass them on to a clearnet facing mail relay. You may or may not want to create the second instance by running
postmulti -e init
postmulti -I postfix-clearnet -e create
postmulti -i clearnet -e enable
postmulti -i clearnet -p start
If you created an instance, uncomment the clearnet relay related config in etc/postfix/main.cf and make sure to copy and modify the configuration files from etc/postfix-clearnet too
If you encountered the following issue: postfix: fatal: chdir(/var/spool/postfix-clearnet): No such file or directory you can just copy the chroot from the default postfix instance like this cd /var/spool/ && cp -a postfix/ postfix-clearnet/
After copying (and modifying) the posfix configuration, you need to create databases out of the mapping files (also each time you update those files):
postalias /etc/aliases
postmap /etc/postfix/canonical /etc/postfix/sender_login_maps /etc/postfix/transport
postmap /etc/postfix-clearnet/canonical /etc/postfix-clearnet/sasl_password /etc/postfix-clearnet/transport #only if you have a second instance
To save temporary files in memory, add the following to /etc/fstab:
tmpfs /tmp tmpfs defaults,noatime 0 0
tmpfs /var/log/nginx tmpfs rw,user,noatime 0 0
To harden the system and hide pids from non-root users, also add the following:
proc /proc proc defaults,hidepid=2 0 0
And add the noatime,usrjquota=aquota.user,jqfmt=vfsv1 options to the /home mountpoint (if not a separate partition, the / mointpoint and noatimeto /. Then initialize quota (replace /home with /, if you do not have a separate partition):
mount -o remount /home
quotacheck -cMu /home
quotaon /home
In some cases, you might get an error, that quota is not supported. This is usually the case in virtual environments. Make sure you have the full kernel installed, not one with a -virtual package. They usually are linux-image-amd64, linux-image-arm64 or linux-image-generic, depending on your distribution. Also make sure, you are running a real virtual machine (e.g. KVM). Some providers sell containerized VPSes (e.g. OpenVZ), which means you don't run your own kernel...
Enable the PHP-FPM default instances and nginx:
systemctl enable php7.4-fpm@default
systemctl enable php8.0-fpm@default
systemctl enable nginx
Install sodium_compat for v3 hidden_service support
cd /var/www && composer install
Create a mysql user for phpmyadmin and cofigure it in /var/www/html/phpmyadmin/config.inc.php and fill $cfg['blowfish_secret'] with random characters:
mysql
CREATE USER 'phpmyadmin'@'%' IDENTIFIED BY 'MY_PASSWORD';
CREATE DATABASE phpmyadmin;
GRANT ALL PRIVILEGES ON phpmyadmin.* TO 'phpmyadmin'@'%';
FLUSH PRIVILEGES;
quit
mysql phpmyadmin < /var/www/html/phpmyadmin/sql/create_tables.sql
Create a mysql user with all permissions for our hosting management:
mysql
CREATE USER 'hosting'@'%' IDENTIFIED BY 'MY_PASSWORD';
GRANT ALL PRIVILEGES ON *.* TO 'hosting'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
quit
Then edit the database configuration in /var/www/common.php and /etc/postfix/sql/alias.cf
Last but not least setup the database by running
php /var/www/setup.php
Enable systemd timers to regularly run various managing tasks:
systemctl enable hosting-del.timer && systemctl enable hosting.timer
Final step is to reboot wait about 5 minutes for all services to start and check if everything is working by creating a test account.
