else
pkill -9 magent
fi
注意：如果将故障的memcached节点修复后，缓存是不会再通过到已修复的节点上的，如果是magent指定的主节点故障，那么主节点的缓存数据会丢失，修复后不能立刻重启memcached服务，如果重启，客户端会去查询主节点的数据。并发高的网站会拖死数据库。因此，建议一般业务低峰期的时候再启动memcached主节点服务。然后通过magent再指定主缓存节点和备缓存节点。
1.若memcached读写的数据多，一定将关掉防火墙或将防火墙设置为不使用跟踪链接表，否则会导致/var/log/message报错“kernel: nf_conntrack: table full, dropping packet”，详情请参考本博客中的博文http://blog.csdn.net/yanggd1987/article/details/45886913。
2.使用service iptables stop关掉，并且不能用iptables -L -vnx查看，因此使用此命令会将防火墙开启，虽然规则是清空的，但仍会记录连接跟踪表。
