由于在网上找不到很好的解释,因此我一直在尝试 php-fpm 和 nginx 中的错误日志记录。大多数指南都说,如果我想将错误从 php5-fpm 发送回 nginx,我应该将其更改为catch_workers_output
。yes
然而,在我的实验中,我发现即使catch_workers_output
设置为no
,nginx 仍会正确记录错误。
这是我的虚拟主机配置:
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:
Exp 1
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
errors not displayed in stderr when running php5-fpm non-daemonized

我的问题是,即使 php-fpm 没有 stderr 输出 (当catch_workers_output=no
),PHP5-FPM 如何将错误日志发送到 nginx?我在任何地方都找不到相关文档。
答案1
当你的 nginx 配置使用php_admin_value,php_admin_flag和php_flag它会覆盖 php.ini 中的值。注释掉 nginx 设置将保留 php.ini 文件作为控制。
查看 php.ini 文件中的设置显示错误,显示启动错误,错误报告,html_错误和日志错误。那里很可能存在冲突。
