file_server vs php

Once you configured caddy, restart it, or reload configuration file

sudo systemctl restart caddy
#PHP
sudo nano /etc/php/7.4/fpm/pool.d/www.conf

change the following line

user = caddy
group = caddy
listen.group = caddy
listen.owner = caddy

Then restart php-fpm

sudo systemctl restart php7.4-fpm.service
#Postgresql

Allow connecting from local using password:

sudo nano /etc/postgresql/13/main/pg_hba.conf

Change (or add if not exist) this line, the original value is peer, change it to md5

local all all md5

You can give user 'sometwo' permission to connect from remote, by add

host all sometwo 0.0.0.0/0 md5

Then restart postgresql by

sudo systemctl restart postgresql

#Test

Now navigate to your website's root directory, if not exist, create one.

sudo mkdir -p /var/www/php.acytoo.com
sudo chown -R acytoo:acytoo /var/www/php.acytoo.com

For convenience, I have also changed the owner of website's root directory from root user to myself.

nano /var/www/php.acytoo.com/index.php

<html>
<head>
    <title>Test postgresql</title>
</head>
<body>
<?php

$host = "host = 127.0.0.1"; // host address
$port = "port = 5432"; 			// postgresql port
$dbname = "dbname = database_name"; 	// database name
$credentials = "user = sometwo password=notmypassword"; // credentials

$db = pg_connect("$host $port $dbname $credentials");
if (!$db) {
    echo "Error : Unable to open database\n";
} else {
    echo "Opened database successfully\n";
}

?>
</body>
</html>
