I had two container called "mysql-1" and "ubuntu-1".
And I connect each other used
docker run -p 127.0.0.1:3010:80 -itd --link mysql-1 --name=ubuntu-1 my-ubuntu-image:latest
Notice that my-ubuntu-image already had nginx and php, and I changed the config inside the ubuntu-1 like following:
default
server {
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/html/test/;
index index.php index.html index.htm index.nginx-debian.html;
server_name _;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ /index.php$is_args$args;
}
location ~ \.php$ {
try_files $uri /index.php =404;
fastcgi_pass 127.0.0.1:9999;
fastcgi_index index.php;
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
#fixes timeouts
fastcgi_read_timeout 600;
include fastcgi_params;
}
}
www.conf
listen = 127.0.0.1:9999
It works, when I try to run a simple php file without mysql. But now I try to run a php file like following:
<?php
$servername = "localhost";
$username = "root";
$password = "123456";
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
