Tag: FreeNAS

I’ve recently upgraded my FreeNAS server to version 11.3 and I setup my personal WordPress site in a FreeNAS Iocage Jail using PHP-FPM and Nginx web server. There are precious few write ups of this process so I decided to write one (and document my challenges). I hope you enjoy. Before you get started this is of moderate difficulty and there are much easier hosted solutions at WordPress.com. This is mostly an exercise of “is this possible” and the answer is yes!

BTW, many thanks to https://www.mjaleel.com/2019/02/28/20/how-to-setup-wordpress-on-freenas-iocage-jail/ which is the post which I originally used to get myself configured. I’ve added to it and changed a few things. Please note my Iocage Jail section is much different and I’ve added the WordPress configuration steps.

Step 1) Create the Iocage Jail

There are numerous tutorials for doing this. I will be brief here. In the FreeNAS 11.3 web GUI interface, navigate to Jails and select Add. I named mine WordPress, you can choose whichever name suits your fancy; www is another good option. I selected default Jail type and release 11.3-Release (more about this later).

I selected DHCP auto configure for IPv4 which means FreeNAS will request an IP address from your router via DHCP (Dyn Host Config Protocol). Only select NAT if you want to put it on the same IP as your FreeNAS server but that takes some work since FreeNAS also sits on port 80, so save yourself the trouble and select DHCP. I unchecked autoconfigure of IPv6. In general I keep IPv6 off for security reasons. Hit next and then create.

Start your Jail using the FreeNAS web GUI. Note down the IP address of your jail for later. SSH (Secure Shell) into your Freenas (there are many tutorials on how to do that, I’ll leave to the reader) and type jls to view the Jails that have been configured and are running (note the JID or jail identifier). You can see in the screenshot below that my WordPress jail is running on jid 9. Execute the command “sudo exec 9 /bin/tcsh” to ssh into WordPress jail. BTW, there are like a half dozen ways to ssh into a jail, this is just the way I’m most comfortable with.

Step 2) Install packages

Now that you are ssh’ed into your FreeNAS 11.3 jail, we will install a number of software packages. This may or may not get out of date. I will attempt to keep it more or less current. Please note that we’ll install mysql 5.7 packages as the mysql 8.0 package fails when WordPress attempts to connect. Your mileage may vary and of course other RDBMS (Relational Database Management Systems) will also work. I’m a former Sybase DBA and I absolutely love Sybase for what it’s good at… I digress.. Ok, on to the packages…

First, run “pkg update” to fetch the latest package list for your Jail. Next, run “pkg upgrade” to upgrade any deployed package and the Jail software itself (Note, this may take a while if you run on an old Jail). There is another command needed to upgrade to another release (i.e. 11.2 to 11.3 release of FreeNAS) which I’ll leave to the reader.

Execute the following command to download the packages

pkg install nginx php73 mysql57-server mysql57-client php73-xml php73-dom php73-curl php73-ctype php73-json php73-ftp php73-hash php73-session php73-pecl-imagick php73-pecl-memcached php73-tokenizer php73-mbstring php73-fileinfo php73-exif php73-openssl php73-filter php73-zip php73-zlib php73-mysqli php73-iconv php73-gd

It’ll pull in many other dependencies; it became 98 packages on my test machine, 669 MiB. Select “Y” to download and install. PHP packaging is *very* modular in general. If you forget a required package like let’s say php73-ctype and then continue, you’ll eventually get Jetpack connection errors that will have you pulling your hair out for a day until you realize (this happened to me!).

3) Create and Mount Your Datasets

Personally, I like to put software in the Jails and keep data on datasets outside of the Jails. This way I can create or upgrade software components away from the data for no-tears upgrades. I created 2 datasets on my FreeNAS pool named ssl and var. SSL like the description says is all things SSL certs and intermediate certs and CSR’s etc. I keep it separate from the Jails and separate from other datasets as I’ll want to use this with other services (Minecraft minos for instance). Var is for all things Variable that includes logs, WWW root and database backups.

Back at the command line to my WordPress Jail, I changed directory back to the /mnt directory and added two directories for the ssl dataset and the var dataset

Stop the WordPress Jail in the FreeNAS web GUI (in the Jails section). When it is stopped, select Mountpoints to add the mount points you just created.

Next, add the two mount points to the Jail you named WordPress. You will need to do this one at a time and select the source at the top to be the dataset you just created and the destination in the bottom pane which is the directory you created in your Jail. You can use different directory names; just remember what you used.

After you add the 2 mounts, you can go back to the Jails interface in FreeNAS and restart your WordPress jail.

4) Configure your Services to Autostart

Use that jls and jexec process (from end of Step 1) to ssh back into your WordPress Jail. You should notice that the JID number has incremented by 1 (this is expected). Check to make sure the /mnt/ssl and /mnt/var filesystems are mounted and writeable. You can touch a file in each directory and see if it’s written to the appropriate place.

Then type “grep rcvar /usr/local/etc/rc.d/*” to see what the enable configs are for all your services. In this example they are php_fpm_enable, nginx_enable and mysql_enable. Then vi the /etc/rc.conf file to add those configurations and enable them.

You of course can use whichever editor you like. I’m a vi person, emacs looks cool but vi works everywhere. Add those 3 entries at the bottom and save the file. Don’t start any services yet.

5) Configure php-fpm (Note: I have no idea what fpm means, I will speculate freebsd package mgmt)

Back in the ssh command line for your WordPress instance. Run the following command to copy the distributed php.ini (config) file to your instance.

root@wordpress:~ # cp /usr/local/etc/php.ini-production /usr/local/etc/php.ini

Next, edit the php-fpm.conf file

root@wordpress:~ # vi /usr/local/etc/php-fpm.conf

; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;

; Note: This value is mandatory.
pm = dynamic

; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP

; Default Value: 0
;pm.max_requests = 500

; The URI to view the FPM status page. If this value is not set, no URI will be

6) Configure Nginx Web Server

We are getting close; please hang in there! For this section we will create a series of config files for Nginx web server. We will default it to use SSL encryption (you will need to supply your own SSL certs). I can give you the steps to create a self signed SSL cert to test, but you’ll want to get a proper SSL cert (which costs $$$) from your domain registrar or another location.

Create and edit the following configuration files:

• /usr/local/etc/nginx/php_handlers.conf: This config file directs where all the php scripts will be handled.
• /usr/local/etc/nginx/conf.d/redirect.conf: This config file that redirects all the HTTP requests to HTTPS. 
• /usr/local/etc/nginx/ssl.conf: This config file has all the settings defined to enable SSL on the web sever.
• /usr/local/etc/nginx/conf.d/www.conf: This is the default wordpress server config file 
• /usr/local/etc/nginx/nginx.conf: This is the main config file for the nginx webserver.

Create the server hosts configuration directory /usr/local/etc/nginx/conf.d

root@wordpress:~ # mkdir -p /usr/local/etc/nginx/conf.d

Create the /usr/local/etc/nginx/php_handlers.conf configuration file.

root@wordpress:~ # vi /usr/local/etc/nginx/php_handlers.conf
# PHP Handlers

# WordPress
upstream php_wp {
        # This should match value of the "listen" directive in php-fpm pool for www
        # localhost and port 9000
        server 127.0.0.1:9000;
}

Create and edit the /usr/local/etc/nginx/conf.d/redirect.conf file

root@wordpress:~ # vi /usr/local/etc/nginx/conf.d/redirect.conf
server {
    listen 80 default_server;

    # Redirect all HTTP requests to HTTPS with a 301 Moved Permanently response.
    return 301 https://$host$request_uri;
}

Create and edit the /usr/local/etc/nginx/conf.d/www.conf

root@wordpress:~ # vi /usr/local/etc/nginx/conf.d/www.conf
# www - public server
server {
   listen       443 ssl http2;
   server_name  www.example.com example.com;

   root    /mnt/var/www/wordpress;
   index  index.php;

   # php max upload limit cannot be larger than this size
   client_max_body_size 13m;

   # SSL Configuration
   include /usr/local/etc/nginx/ssl.conf;

   location / {
       try_files $uri $uri/ /index.php?$args;
   }

   location ~ \.php$ {
        include        fastcgi_params;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME $request_filename;
        fastcgi_pass   php_wp;  # php handler for www
        fastcgi_buffers 16 16k;
        fastcgi_buffer_size 32k;
   }

   location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
        expires max;
        access_log off;
        log_not_found off;
   }

} # End of www server block

7) Configure SSL for Nginx

Create a self-signed SSL certificate using openssl.

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /mnt/ssl/private/selfsigned.key -out /mnt/ssl/certs/selfsigned.crt

This will only be useful for your testing purposes. All guests to your web server will be prompted with a fun little message that this site cannot be trusted. It’s fine for this tutorial though, you will need to procure your own SSL certificate from your domain registrar or another reputable source. Note that I saved that keyfile and the cert into our mount point for the SSL dataset we created in a previous step.

Create and edit the /usr/local/etc/nginx/ssl.conf file

# Certs sent to the client in SERVER HELLO are concatenated in ssl_certificate

ssl_certificate           /mnt/ssl/certs/selfsigned.crt; # self signed cert
ssl_certificate_key       /mnt/ssl/private/selfsigned.key; # self signed Key

#ssl_verify_client on;

# more secure ssl settings
ssl_protocols             TLSv1.3 TLSv1.2;
ssl_prefer_server_ciphers  on;
ssl_ciphers "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRS
A+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA !RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS";


## verify chain of trust (if needed)
#ssl_trusted_certificate    /mnt/ssl/certs/cacert.pem;

8) Configure mysql database

WordPress leverages a database for much of the dynamic content (posts, users, pages, comments, etc). You’ll need to do a very small amount of configuration prior to first usage of WordPress. First and foremost you’ll need to start up the mysql server.

service mysql-server start

If you receive no errors then your mysql server should be running. you can check by running “netstat -an | grep 3306” and you should see a row starting with tcp4 and ending with LISTEN. If nothing is returned from the above command your mysql server is not running and you’ll need to troubleshoot that.

Next, you will need to run a script to secure the mysql installation. The first step is to login to mysql as root. The root password is either blank (i.e. nothing) or a special file called .mysql_secret in the root home directory that contains the password

mysql_secure_installation

Set the new root password, disable anonymous logins and root logins from external and remove the temp database. You can set password requirements, but if you do then it’ll only allow high strength passwords in WordPress. When the script is done login as root and create the WordPress database.

mysql –u root –p

create database wordpress;

grant all privileges on wordpress.* to 'wpuser'@'localhost' identified by 'wppassword';

flush privileges;

exit

If you made it this far you really deserve a break; maybe a nice cup of camomile tea? Literally this took me like 2 nights to get this far…

9) Download WordPress Installation

WordPress is essentially a bunch of php files, some css and some other files. You can download the latest tarball (i.e a tar.gz archive) from http://www.wordpress.org (don’t mistakenly go to the .com version!). Hit the “Get WordPress” bottom and click the download .tar.gz link. You should scp the tar.gz file from your pc to the FreeNAS server. You should save it in your /var dataset which you mounted in a previous step. Mine is located in /mnt/PavPool/var, so the command from my pc would be:

rich@somecomputer# scp rich@kidney:/mnt/PavPool/var ~/Downloads/Wordpress-5.3.2.tar .

Create a directory called www and extract the WordPress archive there. Make sure the directory structure matches the path you set in www.conf in Step 6. If your jail is expecting /mnt/var/wordpress then the workpress software must be extracted into a folder called wordpress. Make sure the files are directory structure are readable and writeable by your nginx server process.

10) Now Restart everything and Try to Connect

You need to reload and restart all your components to load the configurations files. You will get an error if the configuration files are

root@wordpress:/ # service php-fpm reload

Performing sanity check on php-fpm configuration:
[19-Apr-2020 15:06:35] NOTICE: configuration file /usr/local/etc/php-fpm.conf test is successful

Make sure your php-fpm.conf file passes the validation check. Now restart PHP

root@wordpress:/ # service php-fpm restart

Performing sanity check on php-fpm configuration:
[19-Apr-2020 15:10:18] NOTICE: configuration file /usr/local/etc/php-fpm.conf test is successful

Performing sanity check on php-fpm configuration:
[19-Apr-2020 15:10:18] NOTICE: configuration file /usr/local/etc/php-fpm.conf test is successful

Now reload nginx webe server and restart it. Again, make sure the reload validation step passes (it doesn’t mean that it will functionally work but at least you don’t have typos in your config files.).

root@wordpress:/ # service nginx reload

Performing sanity check on nginx configuration:
nginx: the configuration file /usr/local/etc/nginx/nginx.conf syntax is ok
nginx: configuration file /usr/local/etc/nginx/nginx.conf test is successful

root@wordpress:/ # service nginx restart

Performing sanity check on nginx configuration:

Starting nginx.

Remember the IP address for your wordpress jail that you wrote down from step 1? Well, type that IP address into a web browser. If you are greeted by a webpage by WordPress to initialize your site for the first time then Success.

root@wordpress:/ # netstat -an | grep -i "LISTEN"
tcp4       0      0 *.443                  *.*                    LISTEN
tcp4       0      0 *.80                   *.*                    LISTEN
tcp4       0      0 127.0.0.1.9000         *.*                    LISTEN
tcp4       0      0 127.0.0.1.3306         *.*                    LISTEN
root@wordpress:/ # 

Run a quick netstat check to see if you are listening on the ports you configured in the previous steps: 80 is http traffic (unencrypted) which will foward to 443 which is SSL encrypted by nginx, 9000 is php-fpm, and 3306 is mysql.

11) Configure port forwarding on your wifi router

You are in the home stretch now. Connect to wifi router and login as an admin account. Typically in the WAN section there is a series of options for port fowarding. If any external requests come into your External IP address for port 80 or port 443 you shoudl configure that to redirect or port forward those to the IP address for your wordpress Jail. Make sure your wifi router is configured with your dynamic DNS provider of choice; for example DynDNS. Ultimately traffic to yourdomain.com will be redirected by your dynamic DNS service provider to your externally visiable IP address that is issued to your wifi router (usually thru DHCP) which will then port forward anything on port 80 or 443 to your jail internal NAT-ed (Network Address Translation) IP for WordPress which is where nginx is running. When you initialize your site USE YOUR external domain name in the wordpress config and not the internal IP address. If you mess this up and use your internal IP address then WordPress will look fine for you inside your network where your FreeNAS box is but the formatting will be missing or corrupted for everyone else outside your network that views your site. You can very easily drop your Mysql WordPress database if you chose any of the wrong options and re-create it to reinitilize your site. I hope this was useful to you; it’s a long read but utltimately I’m very happy with the setup!
