Apache访问日志切割
# vim /usr/local/apache2/conf/extra/httpd-vhosts.conf修改日志文件为：
ErrorLog "logs/test.com-error_log" logs目录位置是相对于/usr/local/apache2
CustomLog "logs/test.com-access_log" combined
Apache的common日志格式定义：
# vim /usr/local/apache2/conf/httpd.conf
# The following directives define some format nicknames for use with
# a CustomLog directive (see below).
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %b" common
%h 来源IP 192.168.101.175
%u 用户user1
%t 时间
\"%r\" 动作，get
"%{Referer}i\" 链接地址
"%{User-Agent}i浏览器的Agent
# tail -10 test.com-access_log
192.168.101.175 - - "GET /misc.php?mod=patch&action =pluginnotice&inajax=1&ajaxtarget=plugin_notice HTTP/1.1" 200 63
每天都会有大量的日志，该怎么处理呢？
# vim /usr/local/apache2/conf/extra/httpd-vhosts.conf
ErrorLog "logs/test.com-error_log"
CustomLog "|/usr/local/apache2/bin/rotatelogs -l /usr/local/apache2/logs/test.com-access_%Y%m%d_log 86400" combined
86400s==一天
# ls /usr/local/apache2/logs 此时日志按照天分割
test.com-access_20151201_logtest.com-error_log
Apache如何做到不记录指定文件类型日志？
# !vim
vim /usr/local/apache2/conf/extra/httpd-vhosts.conf
SetEnvIf Request_URI ".*\.gif$" image-request
SetEnvIf Request_URI ".*\.jpg$" image-request
SetEnvIf Request_URI ".*\.png$" image-request
SetEnvIf Request_URI ".*\.bmp$" image-request
SetEnvIf Request_URI ".*\.swf$" image-request
SetEnvIf Request_URI ".*\.js$" image-request
SetEnvIf Request_URI ".*\.css$" image-request
ErrorLog "logs/test.com-error_log"
CustomLog "|/usr/local/apache2/bin/rotatelogs -l /usr/local/apache2/logs/test.com-access_%Y%m%d_log 86400" combined env=!image-reqest
文件结尾不是：gif,jpg,png......才会记录到日志中。
# apachectl -t
Syntax OK
# apachectl restart
重新访问浏览器，打开几个测试页面，查看日志，发现gif，jpg，png....结尾的文件都没有记录到日志
