nginx access log日志分割-Awesome Devin

问题

access.log 大的网络访问下没有几天文件就变得非常大了，一直累计也不是办法啊。单个文件达到了20g。

解决方案

按照时间每天进行切割

找到nginx.conf

在http添加这部分

	map $time_iso8601 $logdate {
	'~^(?<ymd>\d{4}-\d{2}-\d{2})' $ymd;
	default                       'date-not-found';
	}
	access_log  logs/access-$logdate.log ;

http部分如下

http {


    #log_format main    ' "<$http_Cdn_Src_IP>" "{$http_x_real_ip}" "[$http_x_forwarded_for]" "$remote_addr" '
    #                   '$http_user_agent - $remote_user [$time_local] "$request" '
    #                   ' $status $body_bytes_sent "$http_referer" ';
    #access_log  logs/access.log  main;
    #按照日期分割log

        map $time_iso8601 $logdate {
        '~^(?<ymd>\d{4}-\d{2}-\d{2})' $ymd;
        default                       'date-not-found';
        }
        access_log  logs/access-$logdate.log;

    include       mime.types;
    default_type  application/octet-stream;
    proxy_headers_hash_max_size 51200;
    proxy_headers_hash_bucket_size 6400;

    proxy_buffer_size 128k;
    proxy_buffers   32 128k;
    proxy_busy_buffers_size 128k;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';



    sendfile        on;
    tcp_nopush     on;

    client_max_body_size 20m;
    #keepalive_timeout  0;
    keepalive_timeout  65;
    server_tokens off;
    include front/*.conf;
...

实现效果
