CakePHP 2.x 版本的部署，Warning: SplFileInfo::openFile(/app/tmp/cache/persistent/myapp_cake_core_file_map): failed to open stream: Permission denied in /lib/Cake/Cache/Engine/FileEngine.php on line 356

1、CakePHP 2.x 版本的部署，Warning: SplFileInfo::openFile(/mcloud/creditshop_back/creditshopback/app/tmp/cache/persistent/myapp_cake_core_file_map): failed to open stream: Permission denied in /mcloud/creditshop_back/creditshopback/lib/Cake/Cache/Engine/FileEngine.php on line 356。如图1

2、进入目录：/mcloud/creditshop_back/creditshopback/app/tmp/cache/persistent，查看所属用户与用户组，皆为：root。如图2

[root@back-86667bcfcb-p95js /]# cd /mcloud/creditshop_back/creditshopback/app/tmp/cache/persistent
[root@back-86667bcfcb-p95js persistent]# ls -l

3、参考网址：https://book.cakephp.org/2/zh/installation.html 。设置访问权限。app/tmp 目录及其子目录必须同时能够被 web 服务器和命令行用户写入。

HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\  -f1`
setfacl -R -m u:${HTTPDUSER}:rwx app/tmp
setfacl -R -d -m u:${HTTPDUSER}:rwx app/tmp

4、编辑 Dockerfile。确保在 CakePHP 安装中 app/tmp 目录及其全部子目录可以被 web 服务器用户 写入。

    chown -R 775 /mcloud/creditshop_back/creditshopback/app/tmp/ && \

    cd /mcloud/creditshop_back/creditshopback &&\
    HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\  -f1` &&\
    setfacl -R -m u:${HTTPDUSER}:rwx app/tmp &&\
    setfacl -R -d -m u:${HTTPDUSER}:rwx app/tmp &&\

5、升级后，Nginx 用户写入成功，访问正常。
