Ho sperimentato un po 'con la registrazione degli errori in php-fpm e nginx poiché non ho trovato nessuna buona spiegazione sul web. La maggior parte delle guide ha affermato che dovrei passare catch_workers_output
a yes
se desidero inviare nuovamente gli errori da php5-fpm a nginx. Tuttavia, durante i miei esperimenti ho scoperto che anche quando catch_workers_output
è impostato su no
, gli errori vengono ancora registrati correttamente da nginx.
Ecco la mia configurazione di virtualhost:
server {
server_name domain.com;
return 301 http://www.domain.com$request_uri;
access_log off;
}
server {
listen 80;
listen [::]:80;
root /home/websites/domain.com;
index index.php index.html index.htm;
error_log /home/websites/logs/domain.com/error.log warn;
access_log /home/websites/logs/domain.com/access.log;
#switch on gzip
gzip on;
gzip_min_length 1100;
gzip_buffers 10 32k;
gzip_types text/plain application/x-javascript text/xml text/css;
gzip_vary on;
location / {
try_files $uri $uri/ /index.php?q=$uri&$args;
}
location ~* .(gif|jpg|jpeg|png|css|js|ico)$ {
expires 30d;
access_log off;
}
error_page 404 /404.html;
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
# NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
# With php5-cgi alone:
# With php5-fpm:
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
location ~ /\.ht {
deny all;
}
}
Ecco i miei risultati:

La mia domanda è come PHP5-FPM invia i log degli errori a nginx anche se non c'è un output stderr (quando catch_workers_output=no
) da php-fpm? Non riesco a trovarlo documentato da nessuna parte.
