Saya telah bereksperimen sedikit dengan kesalahan login di php-fpm dan nginx karena saya tidak dapat menemukan penjelasan yang bagus di web. Kebanyakan panduan mengatakan saya harus berubah catch_workers_outputmenjadi yesjika saya ingin mengirim kesalahan dari php5-fpm kembali ke nginx. Namun, selama percobaan saya, saya telah menemukan bahwa bahkan ketika catch_workers_outputdiatur ke no, kesalahan masih dicatat dengan benar oleh nginx.
Inilah konfigurasi virtualhost saya:
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;
}
}
Inilah temuan saya:

Pertanyaan saya adalah bagaimana PHP5-FPM mengirim log kesalahan ke nginx bahkan jika tidak ada output stderr (kapan catch_workers_output=no) dari php-fpm? Saya tidak dapat menemukannya didokumentasikan di mana pun.
