安装第三步，初始化系统失败，提示DateTime::__construct():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. We selected the timezone 'UTC' for now,but please set date.timezone to select your timezone.
修改 php.ini 中 date.timezone 值
date.timezone=PRC或者date.timezone = Asia/Shanghai，同时取消这一行代码的注释，即去掉前面的分号
重启php服务即可
