cacti安装报错It is not safe to rely on the system's timezone settings

最近同学们在搭建cacti的时候，出现这个错误，~~~~duang~~~~

1. cacti安装报错It is not safe to rely on the system's timezone settings
   
2. 
   
3. PHP Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

这是什么导致的呢？
解决思路：
1、首先看到代码里面有timezone settings，时区设置的提示，应该能想到是php 关于设置时区的问题。
2、找到php.ini，编辑打开，查找time相关的选项。
3、找到datetime项，把前面的;分号去掉，同时改成如下代码：

1. date.timezone = PRC

复制代码

最后重启httpd服务，/etc/init.d/httpd restart ，问题解决。

这个错误针对yum方式安装的php生效，但是源码安装的还是有问题，大家可以去想想怎么解决源码的警告信息呢。

源码LAMP安装，cacti报错：

In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /usr/local/apache/htdocs/cacti/include/global_constants.php on line 165
