Base Config

Notes:

  1. The Mail Server requires SSL certificates
  2. Occurances of REPLACEME.TLD without comments stating otherwise should have the FQDN substituted for it
  3. Occurances of REPLACEME without comments stating otherwise should have the FQDN without the TLD substituted for it

Swap File

  1. Run dd if=/dev/zero of=/swapfile bs=1M count=2048 then chmod 600 /swapfile followed by mkswap /swapfile and swapon /swapfile
  2. Set the system up to mount the swap file at boot by adding /swapfile none swap defaults 0 0 to the bottom of /etc/fstab

Web Server

Package Requirements for Web Server

nginx, php, php-apcu-bc, php-fpm, php-composer, php-gd, php-imap, php-intl, php-mcrypt, php-memcached, php-geoip, geoip-database geoip-database-extra, memcached, mariadb, bower, gulp, npm, certbot

Folders for Web Server

nginx, php, systemd

Setup Instructions for Web Server

  1. Install the packages in the Package Requirements above
  2. Copy the folders above that aren't already configured to their equivalent location in /etc
  3. In /etc/nginx/sites-available/REPLACEME.TLD.conf and /etc/systemd/system/letsencrypt.service
  4. Rename /etc/nginx/sites-available/REPLACEME.TLD.conf
  5. Add your site files to /srv/http/REPLACEME.TLD where public assets are located in /srv/http/REPLACEME.TLD/public
  6. Create a symlink from /etc/nginx/sites-available/REPLACEME.tld.conf to /etc/nginx/sites-enabled/REPLACEME.tld.conf
  7. Run openssl dhparam -out /etc/nginx/dhparam.pem 4096 to generate the diffie-hellman parameter
  8. Run systemctl start php-fpm nginx to start the web services and systemctl status php-fpm and systemctl status nginx to check for errors
  9. If there were no errors in the previous command, run systemctl enable php-fpm nginx to enable the web services at boot
  10. Ensure the public web directory exists and run systemctl start letsencrypt to generate the SSL certificates
  11. Run systemctl start certbot-renewal.timer and systemctl enable certbot-renewal.timer to start and enable the auto-renewal process

MySQL Config

  1. Add bind-address = 127.0.0.1 to /etc/mysql/my.cnf
  2. Run mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
  3. Run systemctl start mysqld and systemctl enable mysqld to start mysqld and enable it at boot
  4. Run mysql_secure_installation.
  5. Create a new password.
  6. Say yes to everything (e.g. "Remove anonymous users? Disallow root logging remotely? Remove test database and access to it? Reload privilege tables now?")

Mail Server

Package Requirements for Mail Server

dovecot, postfix, procmail, opendkim

Folders for Mail Server

dovecot, pam.d, postfix, procmailrc, skel, systemd, opendkim

Setup Instructions for Mail Server

  1. Install the packages in the Package Requirements above
  2. Copy the folders above that aren't already configured to their equivalent location in /etc
  3. Add an A DNS record for the FQDN and a hostname for the server
  4. Set the hostname of the server with hostnamectl set-hostname SOMETHING.REPLACEME.TLD where SOMETHING.REPLACEME.TLD is the server hostname
  5. Add the hostname of the server to the end of the line starting with 127.0.0.1 in /etc/hosts
  6. In /etc/dovecot/dovecot.conf and /etc/opendkim/opendkim.conf replace occurances of REPLACEME.TLD and occurances of REPLACEME with the first part of the hostname
  7. In /etc/postfix/main.cf replace occurances of REPLACEME.TLD with the hostname (not the name)
  8. Run opendkim-genkey -r -s REPLACEME -d REPLACEME.TLD where REPLACEME is the first part of the hostname
  9. In /etc/postfix/aliases, replace the instance of REPLACEME with the user that should receive domain-level emails
  10. Run newaliases to update the aliases database with the contents of /etc/postfix/aliases
  11. Run systemctl start postfix dovecot opendkim to start the mail services and systemctl status postfix dovecot opendkim to check for errors
  12. If there were no errors in the previous command, run systemctl enable postfix dovecot opendkim to enable the mail services at boot
  13. Create an MX DNS record for REPLACEME.TLD containing the hostname (REPLACEME.TLD can usually be left out of the input field)
  14. Create a TXT DNS record for the host REPLACEME._domainkey.REPLACEME.TLD containing v=DKIM1; k=rsa; s=email; p=PASSWORD, replacing the occurance of REPLACEME with the first part of the hostname and PASSWORD with the string following p= in /etc/opendkim/REPLACEME.txt (REPLACEME.TLD can usually be left out of the input field)
  15. Create a TXT DNS record for the host REPLACEME.TLD containing v=spf1 mx -all (REPLACEME.TLD can usually be left out of the input field)
  16. Create a TXT DNS record for the host _dmarc.REPLACEME.TLD containing v=DMARC1; p=none (REPLACEME.TLD can usually be left out of the input field)
  17. Set the reverse DNS record for the VPS to the hostname

Add Accounts

  1. Create an account by running useradd -m -d /home/REPLACEME -s /bin/bash REPLACEME (replacing REPLACEME with the username associated with the mail account)
  2. Set the password by running passwd REPLACEME (replacing REPLACEME with the username associated with the mail account)
