apache logformat access_log 有大用 有大大用 有大大大用

第一个例子  %{Host}i 表示域名

<IfModule log_config_module>

    #

    # The following directives define some format nicknames for use with

    # a CustomLog directive (see below).

    #

    LogFormat "%h %l %u %t %{Host}i \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

    #LogFormat "%h %l %u %t \"%r\" %>s %b" common

    LogFormat "%h %l  %u %t \"%v\" \"%r\" %>s %b duration %T/%D %{msec_frac}t" common

    <IfModule logio_module>

      # You need to enable mod_logio.c to use %I and %O

      LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio

    </IfModule>

    # The location and format of the access logfile (Common Logfile Format).

    # If you do not define any access logfiles within a <VirtualHost>

    # container, they will be logged here.  Contrariwise, if you *do*

    # define per-<VirtualHost> access logfiles, transactions will be

    # logged therein and *not* in this file.

    #

    CustomLog "logs/access_log" combined

    #

    # If you prefer a logfile with access, agent, and referer information

    # (Combined Logfile Format) you can use the following directive.

    #

    #CustomLog "logs/access_log" combined

</IfModule>

第二个例子  \"%v\" 也表示域名

<IfModule log_config_module>

    #

    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

    LogFormat "%h %l %u %t  \"%v\"  \"%r\" %>s %b" common

    <IfModule logio_module>

      # You need to enable mod_logio.c to use %I and %O

      LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio

    </IfModule>

    #

    # The location and format of the access logfile (Common Logfile Format).

    # If you do not define any access logfiles within a <VirtualHost>

    # container, they will be logged here.  Contrariwise, if you *do*

    # define per-<VirtualHost> access logfiles, transactions will be

    # logged therein and *not* in this file.

    #

    CustomLog "logs/access_log" common

    #

    # If you prefer a logfile with access, agent, and referer information
