#有redis的要加redis依赖，然后重启PHP-fpm
/etc/init.d/PHP-fpm restart
vim /etc/PHP-fpm.d/www.conf
user = Nginx
group = Nginx
PHP_value[session.save_handler] = files
PHP_value[session.save_path] = /var/lib/PHP/session
PHP_value[soap.wsdl_cache_dir] = /var/lib/PHP/wsdlcache

session目录写入的权限
Chmod 755 -R /var/lib/PHP

如果你想把session写入redis，需要安装PHP的redis扩展包
yum search PHP70w-pecl-redis.x86_64 #如果安装版本不一样PHP的session就无法保存到redis中
vim /etc/PHP-fpm.d/www.conf
user = Nginx
group = Nginx
PHP_value[session.save_handler] = Redis
PHP_value[session.save_path] = 'tcp://192.168.1.2:6688'
PHP_value[soap.wsdl_cache_dir] = /var/lib/PHP/wsdlcache
