我一直在尝试使用PHP-fpm和Nginx中的错误记录,因为我在网上找不到任何好的解释.大多数指南说如果我想将PHP5-fpm中的错误发送回Nginx,我应该将catch_workers_output更改为yes.但是,在我的实验中,我发现即使将catch_workers_output设置为no,Nginx仍会正确记录错误.
这是我的virtualhost配置：
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;
}
}
以下是我的发现：

poolconf:
; catch_workers_output = no (commented out)
PHP_admin_value[error_log] = /var/log/fpm-PHP.www.log
PHP_admin_flag[log_errors] = on
; PHP_flag[display_errors] = 0
result:
errors not shown in browser
error written in /var/log/fpm-PHP.www.log
error not written in virtualhost error-log in Nginx

我的问题是PHP5-FPM如何将错误日志发送到Nginx,即使PHP-fpm没有stderr输出(当catch_workers_output = no时)？我无法在任何地方找到它.
