Nginx 错误日志不起作用

我尝试了很多方法但无法使错误日志工作，但访问日志工作正常。

这里提到的解决方案对我来说不起作用：

http://mailman.nginx.org/pipermail/nginx/2009-February/009567.html（尝试将错误作为 error_log pram - 没有成功）

http://forum.nginx.org/read.php?2,58447,58447（停止 nginx 后没有陈旧进程）

以下是虚拟主机信息：

server {
        server_name .qa.domain.ca;
        root /var/www/qa.domain.ca;
        access_log /var/log/nginx/qa.domain.ca/access.log;
        error_log /var/log/nginx/qa.domain.ca/error.log;
        index index.html index.htm index.php;

        # redirect to non-www
        if ($host ~* ^www\.(.*)){
                set $host_without_www $1;
                rewrite ^/(.*)$ $scheme://$host_without_www/$1 permanent;
        }

    if (-d $request_filename){
                rewrite ^/(.*[^/])$ /$1/ permanent;
        }
        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to index.html
                try_files $uri $uri/ /index.php;
                # Uncomment to enable naxsi on this location
                # include /etc/nginx/naxsi.rules
        }
        location ~ .php$ {
                if (!-f $request_filename) {
                        return 404;
                }
                fastcgi_pass   127.0.0.1:9000;
                fastcgi_index  index.php;
                fastcgi_param  SCRIPT_FILENAME  /var/www$fastcgi_script_name;
                include fastcgi_params;
        }
}

您的设置（可能基于现有的众多过时的博客文章之一）效率低下。

这是一个更好的设置：

server {
    server_name www.qa.domain.ca;
    # redirect to non-www
    return 301 http://qa.domain.ca$request_uri;      
}

server {
    server_name qa.domain.ca;
    root /var/www/qa.domain.ca;
    access_log /var/log/nginx/qa.domain.ca/access.log;
    error_log /var/log/nginx/qa.domain.ca/error.log;
    index index.html index.htm index.php;

    # Using "if" for redirection is inefficient as every request will be tested
    # Also, the "-d" test is redundant given the use of "try_files" below

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to index.html
        try_files $uri $uri/ /index.php;
        # Uncomment to enable naxsi on this location
        # include /etc/nginx/naxsi.rules
    }
    location ~ .php$ {
        # This "if" block will work as long as every php file physically exists
        # and you don't use a php app that uses rewriting of pseudo files
        # I personally prefer to use "location ~ \..*/.*\.php$ { return 400; }"
        if (!-f $request_filename) {
            return 404;
        }
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /var/www$fastcgi_script_name;
        include fastcgi_params;
    }
}

至于 error_log 查询，没有理由它不能在任何配置下工作。

除了将 PHP 升级到最新版本外，还应该修复你遇到的错误，您还可以让 PHP 生成自己的错误日志。例如，我有一个系统，其中 PHP 记录到 syslog。您可以使用以下方式控制此操作指令error_log​在 php.ini 中。
