限制 Apache日志文件大小的方法

通常我们是在{$apache}/conf/httpd.conf中设置apache的参数，然而我们并没有发现可以设置日志文件大小的配置指令，通过参考http://httpd.apache.org/docs/2.0/programs/rotatelogs.html，可以用apache 自己的程序 rotatelogs.exe(位于 {$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
linux/unix下 应该类似。
