}

所有子站点配置文件都没有配置access_log off

以下是一个子站点配置文件vhost/app3.abc.com.conf：

server
    {
        listen       80;
        server_name app3.abc.com;
        index index.html index.htm index.php default.html default.htm default.php;
        root  /home/wwwroot/abc.com/guide;
        location ~ .*\.(php|php5)?$
            {
                try_files $uri =404;
                fastcgi_pass  unix:/tmp/php-cgi.sock;
                fastcgi_index index.php;
                include fcgi.conf;
            }
        location /{

            rewrite ^([^\.]*)/wenda/(\w+)/(\w+)\.html$ $1/index.php?r=wenda/$2/$3 last;

            #rewrite ^([^\.]*)/([a-zA-Z]+)/([a-zA-Z]+)\.html$ $1/index.php?r=$2/$3 last;        
                        
            if (!-e $request_filename) {
                return 404;
            }
        }
        
        location /ueditor{
            autoindex on;
            }        
        
        location ~ .*\.(gif|jpeg|png|bmp|swf)$
            {
                expires      30d;
            }

        location ~ .*\.(js|css)?$
            {
                expires      12h;
            }

        #access_log  /home/wwwlogs/visit.log  access;
        error_log  /home/wwwlogs/wenda_error.log  crit;
        }

有很多个子站点配置文件，都没有配置access_log off

通过上述配置之后，每次把nginx/logs/access.log日志文件删除后，第二天一来必定产生新的access.log日志文件，有1G左右大小。公司的需求是关闭nginx的access.log功能，也就是不让nginx记录访问日志。谁有更好的解决方案吗？非常感谢！

解决方案

答案已经找到。

其实网上说的 access_log /dev/null; 只是针对nginx的error_log而言的。如果想关闭error_log，那么就用error_log /dev/null（看老外是这么做的）。

但是想关闭access_log的话，直接在nginx.conf的http模块中配置access_log off;即可。需要注意的是，已经继承了http模块的那些模块不要再设置access_log off;了。 比如，我已经在http模块中设置了access_log off;，那么就不要在http模块所包含的server模块或location模块中设置access_log off;，以及虚拟主机目录(vhost)下的配置文件也不要添加access_log off;。

纯生产环境实战经验。
