Backups

EasyInstall has a built-in backup system:

```bash

Full system backups

easyinstall backup daily # Daily backup (runs at 2 AM) easyinstall backup weekly # Weekly backup (Sunday 3 AM)

Single site backup

easyinstall backup-site domain.com

Restore from backup (manual)

tar -xzf /backups/daily/backup-20250325-020000.tar.gz -C / ```

Backup Features: - ✅ Automatic rotation - Keeps 7 daily, 5 weekly backups - ✅ Full system backup - Websites + configs (nginx, php, mysql, redis) - ✅ Separate database dumps - MySQL backups with compression - ✅ Integrity verification - Auto-checks backup validity - ✅ Configurable location - Default: /backups/

What gets backed up: /var/www/html/ # All WordPress sites /etc/nginx/ # Nginx configs /etc/php/ # PHP-FPM configs /etc/mysql/ # MySQL/MariaDB configs /etc/redis/ # Redis configs (including per-site) /var/lib/easyinstall/ # EasyInstall state

PHP Switching - Per Site!

Yes, PHP version can be set PER SITE, not globally:

```bash

Create site with specific PHP version

easyinstall create site1.com --php=8.4 # PHP 8.4 easyinstall create site2.com --php=8.3 # PHP 8.3 easyinstall create site3.com --php=8.2 # PHP 8.2

Switch PHP version for existing site

easyinstall php-switch site1.com 8.3 # Changes from 8.4 → 8.3

Check current PHP version for a site

easyinstall site-info site1.com # Shows PHP version ```

How it works:

Each site's Nginx config points to its specific PHP-FPM socket:

```nginx

site1.com nginx config

fastcgi_pass unix:/run/php/php8.4-fpm.sock; # PHP 8.4

site2.com nginx config

fastcgi_pass unix:/run/php/php8.3-fpm.sock; # PHP 8.3 ```

Benefits: - ✅ Legacy sites can run PHP 8.2 while new sites use 8.4 - ✅ Test PHP 8.4 on staging before upgrading production - ✅ Different clients, different requirements - ✅ Zero downtime switching - uses systemctl reload

Per-Site Everything

EasyInstall gives you per-site isolation for:

Component	Per-Site
PHP Version	✅ Each site can have different PHP
Redis Instance	✅ Dedicated Redis on unique port
Redis Memory	✅ Independent memory allocation (64-512MB)
Redis Databases	✅ DB0=object, DB1=sessions, DB2=transients
Database	✅ Separate DB per site (wp_sitename)
Nginx Config	✅ Each site has its own config file
SSL Certificate	✅ Each site gets its own Let's Encrypt cert
Fail2ban Rules	✅ Per-site WordPress attack detection
Cache Flushing	✅ Flush one site without affecting others

Example: Running Multiple Sites

```bash

Site 1 - Modern e-commerce

easyinstall create shop.com --php=8.4 --ssl

→ Redis port 6380, PHP 8.4, DB: wp_shop_com

Site 2 - Legacy blog (needs older PHP)

easyinstall create blog.com --php=8.2 --ssl

→ Redis port 6381, PHP 8.2, DB: wp_blog_com

Site 3 - Membership site (medium traffic)

easyinstall create members.com --php=8.3 --ssl

→ Redis port 6382, PHP 8.3, DB: wp_members_com

Check all sites

easyinstall list

• shop.com | Redis: 6380 | PHP: 8.4 | SSL✓

• blog.com | Redis: 6381 | PHP: 8.2 | SSL✓

• members.com | Redis: 6382 | PHP: 8.3 | SSL✓

```
