I’ve been able to setup (with much help from here 
) a local WordPress development setup. Here is the current working lamp.nix file:
{ config, pkgs, lib, ... }:
let
php' = pkgs.php83.buildEnv {
extensions = ({ enabled, all }: enabled ++ (with all; [
xdebug
imagick
]));
extraConfig = ''
memory_limit = 1024M
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.idekey = gdbp
'';
};
webPath = "/var/www";
# webPath = "/mnt/vault/www";
sites = [
"example.org"
];
in
{
networking.hosts = {
"127.0.0.1" = [
"example.org"
];
};
services.mysql.enable = true;
services.mysql.package = pkgs.mariadb;
services.mysql.ensureDatabases = [
"example.org"
];
services.mysql.ensureUsers = [
# NOTE: it is important that `name` matches your `$USER` name, this allows us to avoid password authentication
{ name = "sergio";
ensurePermissions = {
"*.*" = "ALL PRIVILEGES";
};
}
];
services.phpfpm.pools."example.org" = {
user = "sergio";
group = "users";
phpPackage = php';
settings = {
"listen.owner" = config.services.caddy.user;
"listen.group" = config.services.caddy.group;
"pm" = "dynamic";
"pm.max_children" = 5;
"pm.start_servers" = 2;
"pm.min_spare_servers" = 1;
"pm.max_spare_servers" = 5;
"php_admin_value[error_log]" = "stderr";
"php_admin_flag[log_errors]" = true;
"catch_workers_output" = true;
};
};
services.caddy.enable = true;
services.caddy.virtualHosts."https://example.org:443".extraConfig = ''
root * ${webPath}/example.org
php_fastcgi unix/${config.services.phpfpm.pools."example.org".socket}
file_server
'';
# automatically create a directory for each site you will work on with appropriate ownership+permissions
systemd.tmpfiles.rules = [
"d ${webPath}/example.org 0755 sergio users"
];
}
If I change webPath to "/mnt/vault/www" (the NFS server), I get a 403 error. I think it’s from Caddy, though not sure. I can access a test.php file on the server, just not the WordPress front or back end, so it’s kinda/sorta working…
File permissions are the same on both ends and so are the files:

Not sure where to go from here as I’m just getting started with NixOS. Any ideas/help woudl be very much appreciated.
The logs for the various services should provide you more information.
Usually you can look at them with:
journalctl -u SERVICENAME.service
If you don’t know the service name you can either try to find it with systemctl list-units or look at the global log with plain journalctl. It might require sudo to view certain logs.
When I did that, for phpfpm and cady nothing seemed to change much… I’ll have another go at it when I get to my computer. Thanks.

Can’t seem to find anything wrong with the configuration or services. Only difference I can think of is one has files accessed through NFS the other locally.
This is what I’m seeing when restarting the services:
systemctl restart caddy.service caddy-api.service phpfpm-nerdpress.localhost.service phpfpm.target phpfpm.slice mysql.service
sudo journalctl -u caddy.service -u mysql.service -u phpfpm-nerdpress.localhost.service -f

Issue was having sub-volumes shared in NFS. I moved them all to the same directory and shared them one by one. All set now! Hope this helps somebody. I turned out to be an NFS config issue…
