Apache internal dummy connection 解决

vivion34

Apache 日志出现大量的::1 - - [27/Dec/2009:16:36:44 +0800] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"
日志。。其实对系统无影响。
这些日志是apache2.2版本后，对自身进程的监听所产生的日志~~
具体说明下：
When the Apache HTTP Server manages its child processes, it needs a way
to wake up processes that are listening for new connections. To do
this, it sends a simple HTTP request back to itself. This request will
appear in the access_log file with the remote address set to the
loop-back interface (typically 127.0.0.1 or ::1 if IPv6 is configured).
If you log the User-Agent string (as in the combined log format), you
will see the server signature followed by "(internal dummy connection)" on non-SSL servers. During certain periods you may see up to one such request for each httpd child process.
你可以过滤掉这些日志
在WIKI已经有解决方法：
http://wiki.apache.org/httpd/InternalDummyConnection
具体是设置：
SetEnvIf Remote_Addr "127\.0\.0\.1" loopback
在你的CustomLog 未尾加上 env=!loopback
例如：
SetEnvIf Remote_Addr "::1" loopback
CustomLog "|cronolog -r /usr/bin/gzip logs/ads_access_log.%Y%m%d" combined env=!loopback
SetEnvIf Remote_Addr "127\.0\.0\.1" loopback
这里引号里会出现2种情况。随便改~~
还有一种解决方案：就是在httpd.conf 新建一个虚拟主机。必须排在最前面。
因为apache这种机制，只针对第一个虚拟主机有效
你再不保存access日志就OK了
