dnf install gcloud
console.cloud.google.com
Compute engine
create VM
pick image
20G
but for machine type, select micro 1 shared 0.6 GB
pick a region
firewall click on both http and https
wordpress (not sure if I need to do this) this will create an external ip address as well. yippeee
creation takes about 2 min.
Next we run the gcloud command to connect to the newly created instance.
Copy the command from the website and paste into a terminal.
Once booted, we do a sudo dnf upgrade. (if we have installed a CentOS image)
Now our micromachine is up and updated.

1.1 Step 2)

the micro image only has 582 MB RAM, so we need to add a swap file.

htop to check,
sudo fallocate -l 1G /swapfile
sudo dd if=/dev/zero of=/swapfile bs=1024 count=1048576
sudo chmod 600 /swapfile (to protect it to just root read/write
sudo mkswap /swapfile
sudo swapon /swapfile
htop

Then reboot /etc/fstab

/swapfile swap swap defaults 0 0

ALWAYS after modifying the /etc/fstab, you should do a sudo mount -a to confirm that everything mounts and that you haven't made an error in your /etc/fstab file edits.

htop (should show 1 Gig of space)

1.2 Step 3)

Install LAMP stack.

THe easiest way is to do a bundle:

sudo dnf install tasksel ??? or is this just an apt get ??
sudo tasksel install lamp-server
sudo dnf install lamp-server

Step 3.5) Add extra stuff:

sudo apt install php-curl php-gd php-mbstring php-xml php-xmlrpc

1.3 Step 4)

configuration.

get the static IP for this machine? - curl ifcofnig.me 15.4.5.2

Copy this and add it to your domain, an A record. ( chris cheated with his, and just used a /etc/hosts file ) He created a bogus domain site: squaregatorisfornoobs.com He did this BOTH on the new micro vm in the cloud, as well as his home machine.

1.4 Step 5)

Configure Apache

cd /etc/apache2/sites-available setup the domain name in the apache config file: /etc/apache2/sites-available

backup (cp) the existing one to an .original file Then sudo cp 000.default.conf zintis.net.conf

sudo -i edit zintis.com.conf

<Directory /var/www/html>
    Require all granted
</Directory>
ServerName zintis.net
ServierAlias www.zintis.net
DocumentRoot /var/www/html

disable the default web site: 2dissite 000-default.conf

a2ensite zintis.net.conf Then activate by reload (what is the difference between reload and restart?): systemctl reload apache2

2 php

You cna do this once, from the terminal and then leave it alone. As follows:

mysql -u root

mysql>CREATE DATABASE wordpress;
mysql>GRANT ALL ON wordpress.* TO l'wordpressuser' IDENTIFIED BT 'Secure!2345!'
mysql>quit

mysql_secure_installation
> run through script to lock down your mysql setup

2.1 edit .ini ???=

cd /etc/php/7.2/apache2 vi php.ini

max_input_time = 30
upload_max_filesize = 30M

post_max_size = 25M

3 Create proper web page

cd /var/www/html
mv index.html index.original.html

create your web page root and save as index.html

wget https://wordpress.org/latest.tar.gz

tar -xvf latest.tar.gz.

cd wordpress mv * ..

3.1 cleanup

rm latest.tar.gz

Before you replace the wp-config.php, be ready with all your files, as leaving the wp-config-sample.php as your wp-config.php SHOULD ONLY BE A TEMPORARY moment, as it leaves you WIDE OPEN. So do all your edits ahead, and then end with this next "mv" statement.

mv wp-config-sample.php wp-config.php

vi wp-config.php

define ( 'DB_NAME', 'wordpress' );
define ( 'DB_USER', 'wordpressuser' );
define ( 'DB_PASSWORD', ''Secure!2345!' );

DO NOT LEAVE THE DEFAULT SALTS AND KEYS.... delete them.  ALL OF THEM.
define ( 'AUTH_KEY',      'put your unique phrase here' );
define ( 'SECURE_AUTH_KEY',      'put your unique phrase here' );
define ( 'LOGGED_IN_KEY ',      'put your unique phrase here' );
define ( 'NONCE_KEY',      'put your unique phrase here' );
define ( 'AUTH_SALT',      'put your unique phrase here' );
define ( 'SECURE_AUTH_SALT',      'put your unique phrase here' );
define ( 'LOGGED_IN_SALT',      'put your unique phrase here' );
define ( 'NONCE_SALT',      'put your unique phrase here' );

Then right in the wp-config.php file where the SALTs were, copy the URL link to generate unique phrases: https://api.wordpress.org/secret-key/1.1/salt/ WordPress

And copy these and use these in their place.

4 Now we should have a complete website.

You would actually use wordpress to set up a web site.

5 Apache / wordpress tuning adjustments.

microsites should be tuned as the defaults selected for microsites allow for far greater traffic that can be handled reasonably well. So, tune them down. See the youtube video on tuning here. Use npm pre-fork tuning.

script: needs to see traffic for a couple of days to get valid numbers.

vi /etc/apache2/mods-enabled/mpm_prefork.conf

Richard Forth, on github, wget https://raw.githubusercontent.com/richardforth/apache2buddy/master/apache2buddy.pl which is a perl script.

  NAME
    gcloud - manage Google Cloud Platform resources and developer workflow

SYNOPSIS
    gcloud GROUP | COMMAND [--account=ACCOUNT]
    [--billing-project=BILLING_PROJECT] [--configuration=CONFIGURATION]
    [--flags-file=YAML_FILE] [--flatten=[KEY,...]] [--format=FORMAT]
    [--help] [--project=PROJECT_ID] [--quiet, -q]
    [--verbosity=VERBOSITY; default="warning"] [--version, -v] [-h]
    [--impersonate-service-account=SERVICE_ACCOUNT_EMAIL] [--log-http]
    [--trace-token=TRACE_TOKEN] [--no-user-output-enabled]

DESCRIPTION
    The gcloud CLI manages authentication, local configuration, developer
    workflow, and interactions with the Google Cloud Platform APIs.

GLOBAL FLAGS
     --account=ACCOUNT
    Google Cloud Platform user account to use for invocation. Overrides the
    default core/account property value for this command invocation.

     --billing-project=BILLING_PROJECT
    The Google Cloud Platform project that will be charged quota for
    operations performed in gcloud. If you need to operate on one project,
    but need quota against a different project, you can use this flag to
    specify the billing project. If both billing/quota_project and
    --billing-project are specified, --billing-project takes precedence.
    Run $ gcloud config set --help to see more information about
    billing/quota_project.

     --configuration=CONFIGURATION
    The configuration to use for this command invocation. For more
    information on how to use configurations, run: gcloud topic
    configurations. You can also use the CLOUDSDK_ACTIVE_CONFIG_NAME
    environment variable to set the equivalent of this flag for a terminal
    session.
