Services
MariaDB 10.3 MasterSlave
2 x PHP-Apache 7.1
HAProxy Latest
Redis 4.0
phpMyAdmin STABLE
Overview
The stack is suitable for highload WordPress sites which you can scale as you want. It provides a one-click install solution for scalable WordPress with PHP-Apache and pagespeed module. The whole deployment takes about 10-15 minutes.
How it works
HAProxy on front-end takes requests from users and distributes the load between several nodes.
PHP-Apache comes in two containers with installed and enabled WP-CLI, redis-cache, HyperDB plugins and pagespeed module for Apache.
As a database is used MariaDB in MasterSlave configuration with Redis as object cache
How to deploy a stack
- Click “Deploy to my server”
- Sign in or create an account
- Choose a provider (how to link a hosting provider) and a region if you want to create new hosts or choose the created ones in Select hosts menu
- Fill in necessary fields (if they are, e.g. link to your repository)
- Click Create hosts and services
Minimal recommended configuration
- 2 hosts with 2GB RAM
- 1 host with 1GB RAM
After deploying
You can:
- Scale your app and database in few clicks
- Add your domains
- Add TLS certificates (including free TLS by Let’s Encrypt)
- Check online logs and metrics
- Update app and system requirements of hosts
How to scale
Check a quick gif example on how to scale a database (MariaDB) and an app (Python in this case) or follow the next steps:
To scale a database:
- Open a database service (name “db” in the stack by default)
- Click Scale
- Choose hosts for slaves
- Click Migrate service (means migration of database configuration)
To scale a WordPress service (PHP-Apache):
- Open a PHP-Apache service (name “blog” in the stack by default )
- Click Scale
- Choose hosts you want to use for new PHP-Apache containers
- Click Scale service
There is nothing else needs to do. Load balancer works in Sticky session mode by default and balances PHP-Apache containers. HyperDB plugin is already configured and works well with MasterSlave configuration.
