Memcached¶
各类服务的身份认证机制使用Memcached缓存令牌。缓存服务memecached通常运行在控制节点。在生产部署中，我们推荐联合启用防火墙、认证和加密保证它的安全。
安全并配置组件¶
安装软件包：
# yum install memcached python-memcached
Edit the
/etc/sysconfig/memcachedfile and complete the following actions:Configure the service to use the management IP address of the controller node. This is to enable access by other nodes via the management network:
OPTIONS="-l 127.0.0.1,::1,controller"
注解
Change the existing line
OPTIONS="-l 127.0.0.1,::1".
完成安装¶
启动Memcached服务，并且配置它随机启动。
# systemctl enable memcached.service # systemctl start memcached.service
