Cacti ERROR: opening '*.rrd': No such file or directory 解决方法

error: opening /home/cacti/rra/url-2 no such file or directory

在看Cacti Graph Debug Mode发现如下报错

RRDTool Says:

ERROR: opening '/data/local/nginx/html/cacti/rra/dns-cnc_ucd_load1min_461.rrd': No such file or directory

经过一番网络搜,发现原来是Perl少了组件,解决方法如下:

# perl -MCPAN -e shell# cpan> install LWP::UserAgent
# cpan> install LWP::UserAgent

如果未安装perl或者CPAN或者YAML可以通过下面方式安装
# yum install perl-devel perl-CPAN perl-YAML
