1. Check php.ini
vim /etc/php.ini
Check these items:
session.save_handler = files // session 的存储类型; session.auto_start = 1 //是否自启动 session.save_path = "/var/tmp" //存储位置
2. Check whether /var/tmp has read and write permissions. If not:
chmod 777 -R /var/tmp
3.Check php -fpm configuration file
vim /etc/php-fpm.d/www.conf
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 as php.ini
4. Restart php-fpm
