apache error_log文件中
1. 出现：sh: /usr/bin/rrdtool: No such file or directory
修改 conf_default.php,
$conf[‘rrdtool’] = “/usr/local/rrdtool/bin/rrdtool”;
2. 出现：
(process:4017): Pango-CRITICAL **: No fonts found:
This probably means that the fontconfig
library is not correctly configured. You may need to
edit the fonts.conf configuration file. More information
about fontconfig can be found in the fontconfig(3) manual
page and on http://fontconfig.org
