1、查看apache主配置文件

/usr/local/apache2/conf/extra/httpd-vhosts.conf

2、找到此行    ErrorLog "logs/dummy-host.example.com-error_log"

            CustomLog "logs/dummy-host.example.com-access_log" common

修改成如下配置：

    ErrorLog "logs/test.com-error_log"

    CustomLog "logs/test.com-access_log" combined

LogFormat "%h %l %u %t \"%r\" %>s %b" 此行各参数解析：

%h 来源ip

%l 

%u 用户

%t 时间

%r 动作(具体查看apache官方文档)

3、配置参数将日志切割

同样找到此两行

    ErrorLog "logs/test.com-error_log"

    CustomLog "logs/test.com-access_log" combined

改成以下配置：

    ErrorLog "|usr/local/apache2/bin/rotatelogs -l /usr/local/apache2/logs/test.com-       error_%Y%m%d_log 86400"

    CustomLog "|usr/local/apache2/bin/rotatelogs -l /usr/local/apache2/logs/test.com-access_%Y%m%d_log 86400" combined

注释：86400表示按1天切割
