3. Reference URL: https://book.cakephp.org/2/zh/installation.html . Set access permissions. The app/tmp directory and its subdirectories must be writable by both the web server and command-line users.
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. Edit the Dockerfile. Ensure that the app/tmp directory and all its subdirectories are writable by the web server user in the CakePHP installation.
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. After the upgrade, the Nginx user successfully writes files, and access is normal.
