急救：安装MRTG后没有相应的页面文件生成！！！(已解决)

[nifi]

参考精华贴：
viewtopic.php?t=8891&highlight=mrtg
做好之后在/var/www/mrtg目录下只有这几个文件：
index.html mrtg-l.png mrtg-m.png mrtg-r.png mrtg-ti.png
index.html文件可以正常访问，而且已经列出监控设备的各个端口，但是链接的目标文件确没有，譬如页面上的链接显示：172.31.19.65_1 Traffic Graph，链接的目标文件是：http://localhost/mrtg/172.31.19.65_1.html，但是这个目录下根本就没有。
Not Found

root@ubuntu:/home/sunux# mrtg /var/www/mrtg/index.html
-----------------------------------------------------------------------
ERROR: Mrtg will most likely not work properly when the environment
variable LANG is set to UTF-8. Please run mrtg in an environment
where this is not the case. Try the following command to start:

env LANG=C /usr/bin/mrtg /var/www/mrtg/index.html
-----------------------------------------------------------------------
？？？
难道locale不能是UTF-8？

用env LANG=C /usr/bin/mrtg /etc/mrtg.cfg就可以了，然后出了一大堆信息，发上来做个记录吧：
