3.扩展一下，安装PHP-memcache扩展，防火墙放开11211端口
yum -y install php-pecl-memcache
如果是PHP56版本的应该运行
yum -y install php56w-pecl-memcache
防火墙放开11211
如果是PHP56版本的应该运行
yum -y install php56w-pecl-memcache
防火墙放开11211
firewall-cmd --permanent --zone=public --add-port=11211/tcp
检查端口是否开放
检查端口是否开放
echo stats | nc memcache_host_name_or_ip 11211
