由於開發中需要搭建本地環境，在windows用vmware搭建了一個基於centos7.3的LAMP環境。
當將cakephp開發框架部署到html目錄後，運行就直接報錯了。
報錯代碼如下：
Warning: strtotime(): 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.in /var/www/html/cakephp/lib/Cake/Cache/CacheEngine.php on line 60
Warning: _cake_core_ cache was unable to write 'cake_dev_en-us' to File cache in /var/www/html/cakephp/lib/Cake/Cache/Cache.php on line 323
Warning: /var/www/html/cakephp/app/tmp/cache/persistent/ is not writable in /var/www/html/cakephp/lib/Cake/Cache/Engine/FileEngine.php on line 384

看這段報錯提示大概的意思就是我cache目錄下的相關文件夾沒有寫入權限，但實際上相應的權限我肯定是給了的，那問題出在哪呢？
接着就是各種百度查詢，這其中山路十八彎…
好了，最終發現是selinux的問題！
首先我們需要檢查一下selinux是否開啓
鍵入命令：
/usr/sbin/sestatus -v
如果SELinux status參數爲enabled即爲開啓狀態
開啓了那就關閉它！
vi /etc/selinux/config
將
SELINUX=enforcing
改爲
SELINUX=disabled
ok，wq保存退出
接着重啓服務器
shutdown -r now
接下來就不會報錯了，並且能夠看到歡迎頁面了
由於自己的疏忽，忘了selinux的存在
希望能夠幫到存在同樣問題的你！
