php异常 Message: date(): It is not safe to rely on the system's timezone settings

第一次配置好php后，后台处理是成功的，但是前端看不到结果页面，浏览器直接访问地址，可以看到如下信息：

POST ajax_login 200 OK 172.16.12.76:8086 483 B 172.16.12.76:8086 107ms

我解决的方法比较粗暴，直接修改原始配置文件

/data/soft/php/etc/php.ini   (/data/soft/php为php安装的路径)

在910行更改配置 date.timezone = Asia/Shanghai

然后重启php环境

ps aux| grep php ,查询出来进程id，然后kill，然后

/data/soft/php/sbin/php-fpm start

重新刷新浏览器，问题解决
