apache日志文件access.log在一段时间内就会很庞大百兆甚至几十个吉,尤其大访问量的网站更是如此,这样一来我们在分析apache日志的时候就会消耗很大的内存,那么有没有方法限制一下apache日志的大小呢?答案是肯定的.
我们通常的做法是在{$apache}/conf/httpd.conf中设置Apache的参数，然而我们并没有发现可以设置日志文件大小的配置指令，通过参考http://httpd.apache.org/docs/2.0/programs/rotatelogs.html，可以用apache 自己的程序 rotatelogs.exe(位于 {$apache}/bin/目录下)，来限制日志文件的大小。
Usage: rotatelogs [-l] [offset minutes from UTC] or
Add this:
TransferLog "|rotatelogs /some/where 86400"
or
TransferLog "|rotatelogs /some/where 5M"
to httpd.conf. The generated name will be /some/where.nnnn where nnnn is the system time at which the log nominally starts (N.B. if using a rotation time, the time will always be a multiple of the rotation time, so you can synchronizecron scripts with it). At the end of each rotation time or when the file size is reached a new log is started.
在 Windows 下的设置例子如下：
# 限制错误日志文件为 1M
ErrorLog "|bin/rotatelogs.exe -l logs/error-%Y-%m-%d.log 1M"
# 每天生成一个错误日志文件
#ErrorLog "|bin/rotatelogs.exe -l logs/error-%Y-%m-%d.log 86400"
# 限制访问日志文件为 1M
CustomLog "|bin/rotatelogs.exe -l logs/access-%Y-%m-%d.log 1M" common
# 每天生成一个访问日志文件
#CustomLog "|bin/rotatelogs.exe -l logs/access-%Y-%m-%d.log 86400" common
