PHP/MySQL med failover
- Alle der udvikler PHP til info SKAL læse
Monitorering
Følgende targets skal sættes i nagios for alle 3 nodes
- Galera cync
- Intel SSD
- SW Raid
- MySQL connection
- free space:
- root partition
- /mnt/data

Ting at være obs på
- LOAD DATA INFILE - forventer lokale filer
- LOAD DATA LOCAL INFILE er implicit IGNORE, så der kommer ingen fejl hvis at der er fejl i datafilen
