问题描述
nginx 配置文件nginx.conf：

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！
问题解答
回答1：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。
回答2：把日志路径配置为/dev/null不行吗？
