1. Check
vim /etc/
Check these items:
session.save_handler = files // The storage type of session; session.auto_start = 1 // Whether to start session.save_path = "/var/tmp" //Storage location
2. Check whether /var/tmp has read and write permissions, if not:
chmod 777 -R /var/tmp
3. Check the php-fpm configuration file
vim /etc//
Check these items:
php_value[session.save_handler] = files php_value[session.save_path] = /var/tmp php_value[soap.wsdl_cache_dir] = /var/tmp
Change to the same path
4. Restart php-fpm
/bin/systemctl restart
The above is the detailed content of the general solution for PHP's inability to obtain SESSION information. For more information, please pay attention to my other related articles!
