Linux - nejde Apache - AH02291 Cannot access directory

Dobrý den,

přestal mně z ničeho nic po restartu fungovat webserver Apache 2 na linuxu. Píše to ve statusu toto:

ODPOVĚĎ

Máš tam chybu, že není přístupný adresář /var/log/apache2/ , zkus ho vytvořit a nahodit apache znovu.

ODPOVĚĎ

Díky tak to najelo, všechny weby s PHP jedou, ale nefunguje nextcloud, je tam bílá stránka. Jak povolím výpis chyb z PHP?

ODPOVĚĎ

Zobrazení chyb z PHP uděláš takto:
php --ini
nano /etc/php5/apache2/php.ini
error_reporting = E_ALL | E_STRICT
display_errors = On
display_startup_errors = On
service apache2 restart

ODPOVĚĎ

Tak nefungovala i databáze MySQL:

ŘEŠENÍ:
To bylo způsobeno neexistencí adresáře /var/log/mysql , pak se mysql server rozjel a už znám příčinu. Chtěl jsem šetřit SSD disk od neustálých zápisů do logů a nastavil jsem ukládání logů do ramky přes tmpfs
nano /etc/fstab
tmpfs /var/log tmpfs defaults,noatime,nosuid,mode=0755,size=100m 0 0
