利用du -s -h ./* 命令逐级 缩小包围圈 找到占用磁盘高的文件。

锁定在nginx的日志文件。日志占了14g 

先把日志暂停

nginx.conf 配置文件http 模块 增加access_log off;

 

http {
	include       mime.types;
	default_type  application/octet-stream;

	#charset  gb2312;

	server_names_hash_bucket_size 128;
	client_header_buffer_size 32k;
	large_client_header_buffers 4 32k;
	client_max_body_size 8m;

	sendfile on;
	tcp_nopush     on;

	keepalive_timeout 15;

	tcp_nodelay on;

	fastcgi_buffers 4 64k;

	log_format '$remote_addr - $remote_user [$time_local] "$request" '
	              '$status $body_bytes_sent "$http_referer" '
	              '"$http_user_agent" "$http_x_forwarded_for"';
	include /usr/local/nginx/conf/vhosts/*.conf;
	access_log off ;#0426 删除日志
}

 

 

 

 

 

当然也可以对日志进行每天切割存储。
