我一直在用php-fpm和nginx进行错误日志logging的实验，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的错误发送回nginx，我应该将catch_workers_output更改为yes 。 然而，在我的实验中，我发现即使在catch_workers_output设置为no ，nginx仍然能够正确logging错误。
这是我的虚拟主机configuration：
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; } }
这是我的发现：
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 Exp 2 poolconf: catch_workers_output = yes php_admin_value[error_log] = /var/log/fpm-php.www.log php_admin_flag[log_errors] = on php_flag[display_errors] = 0 results: no error in browser error written in /var/log/fpm-php.www.log error not written to virtualhost error-log by nginx errors not displayed in stderr when running php5-fpm non-daemonized Exp 3 poolconf: catch_workers_output = yes ; php_admin_value[error_log] = /var/log/fpm-php.www.log ; php_admin_flag[log_errors] = on php_flag[display_errors] = 0 results: no errors in browser error NOT written in /var/log/fpm-php.www.log error WRITTEN to virtualhost error-log by nginx errors DISPLAYED in stderr when running php5-fpm non-daemonized Exp 4 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 results: no errors in browser error NOT written in /var/log/fpm-php.www.log error WRITTEN to virtualhost error-log by nginx errors NOT displayed in stderr when running php5-fpm non-daemonized
我的问题是PHP5-FPM如何发送错误日志到catch_workers_output=no即使没有标准输出（当catch_workers_output=no ）从PHP- catch_workers_output=no ？ 我无法在任何地方find它。
当你的nginxconfiguration使用php_admin_value ， php_admin_flag和php_flag时，它将覆盖php.ini中的值。 注释掉nginx设置将会使php.ini文件负责。
在php.ini文件中查看display_errors ， display_startup_errors ， error_reporting ， html_errors和log_errors的设置 。 那里可能有冲突。
