apache配置httpd.conf

新增%{X-FORWARDED-FOR}i

Apache日誌配置檔案中定義了兩種列印格式，分別為combined格式和common格式。

本人使用combined格式

<IfModule log_config_module>
    #
    # The following directives define some format nicknames for use with
    # a CustomLog directive (see below).
    #
    LogFormat "%h ClinetIp:%{X-FORWARDED-FOR}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
    LogFormat "%h %l %u %t \"%r\" %>s %b %{X-FORWARDED-FOR}i" 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
    # (Combined Logfile Format) you can use the following directive.
    #
    #CustomLog "logs/access_log" combined
</IfModule>

Apache日誌格式

日誌格式

Apache日誌配置檔案中定義了兩種列印格式，分別為combined格式和common格式。

combined格式：

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

common格式：

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

宣告使用了combined日誌格式和寫入的檔名。

CustomLog "/var/log/apache2/access_log" combined
