Getting started with PHP on Compute Engine

Running the app in Cloud Shell

1. Install your app dependencies using composer :

     composer install 
    
   

2. Run the PHP built-in web server :

     php -S localhost:8080 
    
   

3. In Cloud Shell, click Web preview, and select Preview on port 8080. This opens a new window with your running app.

4. To stop the local web server, press Control+C .

Deploying to a single instance

This section walks you through running a single instance of your app on Compute Engine.

From Cloud Shell, you can deploy to a single Compute Engine instance virtual machine (VM) which runs your app.

Use a startup script to initialize an instance

You need a way to instruct your instance to download and run your code. An instance can have a startup script that runs whenever the instance is started or restarted.

  set 
  
-e export 
  
 HOME 
 = 
/root # Install PHP and dependencies from apt 
apt-get  
update
apt-get  
install  
-y  
git  
nginx  
php7.2  
php7.2-fpm  
php7.2-mysql  
php7.2-dev  
 \ 
  
php7.2-mbstring  
php7.2-zip  
php-pear  
pkg-config # Install Composer 
curl  
-sS  
https://getcomposer.org/installer  
 | 
  
 \ 
  
/usr/bin/php  
--  
 \ 
  
--install-dir = 
/usr/local/bin  
 \ 
  
--filename = 
composer # Get the application source code 
git  
clone  
https://github.com/googlecloudplatform/getting-started-php  
/opt/src
ln  
-s  
/opt/src/gce  
/opt/app # Run Composer 
composer  
install  
-d  
/opt/app  
--no-ansi  
--no-progress  
--no-dev # Disable the default NGINX configuration 
rm  
/etc/nginx/sites-enabled/default # Enable our NGINX configuration 
cp  
/opt/app/config/nginx/helloworld.conf  
/etc/nginx/sites-available/helloworld.conf
ln  
-s  
/etc/nginx/sites-available/helloworld.conf  
/etc/nginx/sites-enabled/helloworld.conf
cp  
/opt/app/config/nginx/fastcgi_params  
/etc/nginx/fastcgi_params # Start NGINX 
systemctl  
restart  
nginx.service # Install Fluentd 
curl  
-s  
 "https://storage.googleapis.com/signals-agents/logging/google-fluentd-install.sh" 
  
 | 
  
bash # Enable our Fluentd configuration 
cp  
/opt/app/config/fluentd/helloworld.conf  
/etc/google-fluentd/config.d/helloworld.conf # Start Fluentd 
service  
google-fluentd  
restart  
& 

The startup script performs these tasks:

• Installs PHP 7 and PHP 7 FPM.

• Installs and configures NGINX.

• Downloads Composer and runs it for the app code.

• Installs the Cloud Logging agent and configures it to monitor the app logs. This means that the logging configured in the previous steps of this tutorial are uploaded just as if you were using App Engine.

Create and configure a Compute Engine instance

1. Create a Compute Engine instance:

     MY_INSTANCE_NAME 
    = 
    'my-app-instance' 
    ZONE 
    = 
   us-central1-f
   
   gcloud  
   compute  
   instances  
   create  
    $MY_INSTANCE_NAME 
     
    \ 
     
   --image-family = 
   ubuntu-1804-lts  
    \ 
     
   --image-project = 
   ubuntu-os-cloud  
    \ 
     
   --machine-type = 
   g1-small  
    \ 
     
   --scopes  
   userinfo-email,cloud-platform  
    \ 
     
   --metadata-from-file  
   startup-script = 
   scripts/startup-script.sh  
    \ 
     
   --zone  
    $ZONE 
     
    \ 
     
   --tags  
   http-server 
   

   Replace the zone with a development zone, for example us-central1-a . For more information on regions and zones, see Geography and regions .

   This creates a new instance, allows it to access Google Cloud services, and runs your startup script. The instance name is my-app-instance .

2. Check the progress of the instance creation:

   gcloud compute instances get-serial-port-output my-app-instance --zone YOUR_ZONE 
   

   Replace YOUR_ZONE with the zone you deployed your instance to.

   When the startup script is complete, you see the following message:

   startup-script: INFO Finished running startup scripts.

3. Create a firewall rule to allow traffic to your instance:

     gcloud compute firewall-rules create default-allow-http-80 \ 
    --allow tcp:80 \ 
    --source-ranges 0.0.0.0/0 \ 
    --target-tags http-server \ 
    --description "Allow port 80 access to http-server" 
    
   

4. Get the external IP address of your instance:

     gcloud compute instances list 
    
   

5. To see your app running, enter this URL in your browser:

   http:// YOUR_INSTANCE_IP 
   

   Replace YOUR_INSTANCE_IP with the external IP address of your instance.

Manage and monitor an instance

You can use the Google Cloud console to monitor and manage your instance.

1. In the Google Cloud console, go to the VM instancespage.

   Go to VM instances

2. In the list of virtual machine instances, click SSHin the row of the instance that you want to connect to.

3. To view all of the logs generated by your Compute Engine resources, go to the Logs Explorer page.

   Go to Logs Explorer

   Cloud Logging is automatically configured to gather logs from various common services, including syslog .
