日志名称中的变量-Nginx

我在nginx中具有以下默认服务器设置：

# Default HTTP Server
server {
  listen 80 default;
  server_name _;
  access_log /var/log/nginx/$server_name.access.log;
  error_log /var/log/nginx/$server_name.error.log;

  server_name_in_redirect off;

  location / {
    root   domain.com/public;
    index  index.php;
    try_files $uri index.php;
  }

  location ~     \.(html|jpg|jpeg|gif|png|ico|css2|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js)$ {
    root /path/to/domain.com/public;
    expires 30d;
    break;
  }

  charset utf-8;

  location ~ \.php$ {
    include /opt/nginx/conf/fastcgi_params;
    fastcgi_pass  127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param  SCRIPT_FILENAME  /path/to/domain.com/public/index.php;   
  }

  location ~ \.(js|ico|gif|jpg|png|css)$ {
    root /path/to/domain.com/public;
  }
}

我有几个指向服务器的域。我要在此处完成的操作是使日志格式为/var/log/nginx/mydomain.com/access.log或/var/log/nginx/mydomain.com.access.log

相反，我正在得到/var/log/nginx/$server_name.access.log。

如果我尝试使用目录方法，则在检查配置时收到错误消息 nginx: [emerg] open() "/var/log/nginx/$server_name/access.log" failed (2: No such file or directory)

nginx为什么不将变量传递给文件名？

使用nginx / 1.0.0

您需要使用$host变量–仅允许用于access_log指令。
