Twinwork NOTES FreeBSD Post Installation script

This script will automate most of the post-installation install and configuration to set up your FreeBSD environment found at http://notes.twinwork.net/freebsd/.

The original NOTES website is no longer available as it was completely out of date. This script was designed to setup a few customizations from a fresh FreeBSD install. It assumes the following:

  1. Completed the initial install for FreeBSD
  2. ZFS is enabled and uses zroot where FreeBSD is installed
  3. Network is configured

Login locally as root and download the following

fetch https://github.com/kazuo/twinwork-notes/archive/main.zip
unzip main.zip
sh ./twinwork-notes-main/post-install.sh

The post-install.sh script has a couple of options:

    --help          : usage
    --use-zsh       : sets zsh as default shell and installs oh-my-zsh for root
    --use-loki      : uses Twinwork's LOKI poudriere repo
    --use-open      : installs and uses OpenBSD ports of libressl, SSHd, and NTPd    

The post-install.sh script will only install from packages. We'll be using poudriere to build ports

Once the install finishes, log back out and back in as root. You should see the new shell changes.

After the initial settings have been established, add your first user... yourself.

adduser

One more thing about /etc/skel. NOTES used to symlink .profile to .bashrc. This used to work in /etc/skel for 4.x-RELEASE, but any modern version of FreeBSD adduser does not copy over these symlinks. You will need to generate them yourself. I do not know what the work around is... and honestly, I don't care as much since I am the only user who logs into my machines. When you log in as your new user, create a symlink .profile to .bashrc :)

If you didn't already add yourself to the wheel group through the adduser prompts, you can do so manually by editing via pw

pw groupmod -n wheel -m rey

rey is my added self to wheel. This is important. By adding yourself to wheel, you do not need to login as root anymore. Just su to get root access and administer from there. Better yet, instead of using su use sudo instead, but first add yourself to the sudoers file

visudo

Go through the file until you see the following line to uncomment

## Same thing without a password
%wheel ALL=(ALL) NOPASSWD: ALL

Uncommenting that line allows you to use sudo without ever prompting for a password. This is convenient but proceed with caution

Setting up poudriere

We previously used ports to set custom options, but since it's generally bad practice to use both pkg and ports, the better practice is to build your ports in poudriere and set your pkg repo to point to your custom build. Another reason I converted over to building my own packages in poudriere is my increased usage of FreeBSD jails. It was just a lot easier to point the jails to my own package repo than it was to build ports within the jail.

We can automate the initial poudriere setup that twinwork-notes uses by running the following script

sh ./twinwork-notes-main/setup-poudriere.sh

The setup-poudriere.sh script has a couple of options:

    --help          : usage
    --use-loki      : uses Twinwork's Loki poudriere repo

If you specify the --use-loki option, you'll still copy over the main Poudriere.conf file but that repo will be disabled by default and the Loki.conf poudriere file will be enabled. This repo has all of packages built from twinwork-notes plus a few additional ones found in shared.sh. You can always check https://loki.twinwork.net/poudriere. Packages aren't updated on schedule, but closer to once every two weeks or so. They're definitely going to be more up to date than using FreeBSD's quarterly repo. Also, be aware of what Loki is actually building... here's a copy of Loki's /usr/local/etc/poudriere.d/make.conf:

DEFAULT_VERSIONS+=python=3.8 python3=3.8 pgsql=14 php=8.1 samba=4.13

# MariaDB 10.5
DEFAULT_VERSIONS+=mysql=10.5m

OPTIONS_UNSET=ALSA CUPS DEBUG DOCBOOK DOCS EXAMPLES FONTCONFIG HTMLDOCS PROFILE TESTS X11

Whether or not you're choosing Poudriere.conf or Loki.conf, running setup-poudriere.sh will disable FreeBSD's package repo. If you need to install anything else from this point on, follow the rest of the instructions by creating the default ports tree and building all of the prepopulated packages related to these NOTES

poudriere ports -c && poudriere bulk -j 131amd64 -p default -f /usr/local/etc/poudriere.d/pkglist

If you're building all of the packages related to NOTES, this will take awhile... nearly 8 hours on a Intel Core i3 from 2019 (blame llvm for taking so long). But once that's complete, you can also force upgrade all your existsing packages and remove any packages no longer needed

pkg upgrade -f && pkg autoremove

Some configurations of note are: /usr/local/etc/pkg/repos /usr/local/etc/poudriere.d/make.conf

Additional configuration for hosting your own pkg repo

To continue building and serving your own package repo, create an SSL key and cert that clients can use

sudo mkdir -p /usr/local/etc/ssl/{keys,certs}
sudo chmod 0600 /usr/local/etc/ssl/keys
sudo openssl genrsa -out /usr/local/etc/ssl/keys/poudriere.key 4096
sudo openssl rsa -in /usr/local/etc/ssl/keys/poudriere.key -pubout -out /usr/local/etc/ssl/certs/poudriere.cert

Update /usr/local/etc/poudriere.conf and modify the following values

PKG_REPO_SIGNING_KEY=/usr/local/etc/ssl/keys/poudriere.key
URL_BASE=https://sampledomain.com/poudriere

Modify your poudriere conf to add the public key: /usr/local/etc/pkg/repos/Poudriere.conf

Poudriere: {
    url: "file:///usr/local/poudriere/data/packages/131amd64-default",
    mirror_type: "srv",
    signature_type: "pubkey",
    pubkey: "/usr/local/etc/ssl/certs/poudriere.cert",
    enabled: yes,
    priority: 100,
}

Poudriere for arm64 (aarch64)

By default, the jails are for amd64, but you can also build it out for a different architecture. You can run the following below to build out an arm64 repository. I find this useful while testing FreeBSD as a VM guest on Apple Silicon

References:

sudo pkg install emulators/qemu-user-static
sudo sysrc qemu_user_static_enable="YES"
sudo service qemu_user_static start
sudo poudriere jail -c -j 131arm64 -v 13.1-STABLE -a arm64.aarch64 -x
sudo poudriere bulk -j 131arm64 -f /usr/local/etc/poudriere.d/pkglist

Note: There's currently a bug in 13.1-RELEASE that prevents poudriere from working. However, 13.1-STABLE is working but you will get a warning if you try to install any packages from STABLE if you currently have RELEASE installed.

The FEPP install script

I'm not sure what the cool acronym is for FreeBSD, Nginx, PostgreSQL, and PHP is, but we'll go with FEPP! Run the fepp-install.sh script.

sh ./twinwork-notes-main/fepp-install.sh

The script does not automatically start the services for Nginx, PostgreSQL, or PHP-FPM. These services need to be configured first before starting.

PostgreSQL

By default, PostgreSQL's data folder will be in /var/db/postgres/data{version} where version is PostgreSQL's major version (i.e. /var/db/postgres/data14). Also, by default the postgres user's home folder is /var/db/postgres. If you want to change where to store PostgreSQL data, you will need to change postgres' home folder as well.

In this example, I have folder called /nyx and want to place my postgres home folder there. We want to create the postgres home folder, set the the postgres user and group to own the home folder, change the postgres user to the new home folder, enable the postgresql service,and finally set the postgresql_data config in /etc/rc.conf

sudo mkdir -p /nyx/postgres
sudo chown postgres:postgres /nyx/postgres
sudo pw usermod -n postgres -d /nyx/postgres
sudo sysrc postgresql_enable=YES
sudo sysrc postgresql_data=/nyx/postgres/data14

Now you can initialize your DB and start the server.

sudo service postgresql initdb
sudo service postgresql start

If you ever need to migrate your DB folder anywhere, don't forget to move the postgres user's home folder, too.

To log into postgres:

sudo -u postgres psql

You can create a user and DB from a few CLI commands. This will create a local user called plex without a password

sudo -u postgres createuser -e plex

And create a new database called sandbox owned by your new user

sudo -u postgres createdb -e -O plex -E UTF8 sandbox

Then you can login as plex to your sandbox database

psql -U plex sandbox

PHP-FPM

Copy the sample production php.ini in place and enable the service

sudo cp /usr/local/etc/php.ini{-production,}

Modify /usr/local/etc/php-fpm.d/www.conf. We want to use a unix socket instead of TCP as well as setting other options. Find (or add) the keys in the file to modify

listen = /var/run/php-fpm.sock
listen.owner = www
listen.group = www
listen.mode = 0660

Enable and start the PHP-FPM service

sudo sysrc php_fpm_enable=YES
sudo service php-fpm start

Nginx

Add Nginx to /etc/rc.conf and start the service

sudo sysrc nginx_enable=YES
sudo service nginx start

Not Nginx specific, but we should create a new folder for www for all our websites. Set www's home folder and create an .ssh folder. I generally use git as www and add any SSH keys to access my repos.

sudo pw usermod -n www -d /nyx/www
sudo -u www mkdir ~/.ssh

If you want to quickly test PHP, you can use the default Under server block, add the following location block to get PHP up and running:

        # from https://www.nginx.com/resources/wiki/start/topics/examples/phpfcgi/
        location ~ [^/]\.php(/|$) {
            fastcgi_split_path_info ^(.+?\.php)(/.*)$;
            if (!-f $document_root$fastcgi_script_name) {
                return 404;
            }
            root           /usr/local/www/nginx;
            fastcgi_pass   unix:/var/run/php-fpm.sock;
            fastcgi_index  index.php;
            include        fastcgi_params;
            fastcgi_param  HTTP_PROXY       "";
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        }

Here's another sample configuring if you're using the Yii 2 framework.

From https://www.yiiframework.com/doc/guide/2.0/en/start-installation

server {
    charset utf-8;
    client_max_body_size 128M;

    listen 80; ## listen for ipv4
    #listen [::]:80 default_server ipv6only=on; ## listen for ipv6

    server_name sandbox.nyx;
    root        /nyx/www/sandbox/web;
    index       index.php;

    access_log  /nyx/www/sandbox/log/access.log;
    error_log   /nyx/www/sandbox/log/error.log;

    location / {
        # Redirect everything that isn't a real file to index.php
        try_files $uri $uri/ /index.php$is_args$args;
    }

    # uncomment to avoid processing of calls to non-existing static files by Yii
    #location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
    #    try_files $uri =404;
    #}
    #error_page 404 /404.html;

    # deny accessing php files for the /assets directory
    location ~ ^/assets/.*\.php$ {
        deny all;
    }

    location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info ^(.+?\.php)(/.*)$;
        if (!-f $document_root$fastcgi_script_name) {
            return 404;
        }
        fastcgi_pass   unix:/var/run/php-fpm.sock;
        fastcgi_index  index.php;
        include        fastcgi_params;
        fastcgi_param  HTTP_PROXY       "";
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        try_files $uri =404;
    }

    location ~* /\. {
        deny all;
    }
}

If you're doing anything under your www folder, make sure you run any commands as the www user.

sudo -u www mkdir /nyx/www/sandbox

Any time you change your Nginx configuration, be sure to test it before restarting

sudo service nginx configtest
sudo service nginx restart
