ldirectord 用来检测realserver的可用性，但是如果ldirectord失败该怎么办

Submitted by zdx3578 on 周五, 2007-12-14 01:21

怎么保证ldirectord的高可用，不清楚heartbeat是否可以检测？继续查资料！

如果那位大侠可以指点一二不胜感激！

我关闭ldirectord后，ipvs列表清空，是不是那里配置的不对？
这样当ldirectord失败后，集群不是就完了吗？

所以要双击热备。

令人撞墙的"respawning too fast"出错问题
这个问题困扰了我好几天，在lfs系统上安装ha2的时候，respawn的插件每一个能正常启动的，NND，google都搜了底朝天，也没有给出答案，今天终于发现原来是权限的问题。用heartbeat的用户启动不了插件，如ipfail，ccm，crm等。在ha.cf中不要按照上面建议的网上大多数人给出的配置，很简单，因为他们给出的成功做法未必适合自己的系统。
将ha.cf中的
respawn hacluster /usr/lib/heartbeat/ipfail；
apiauth ipfail gid=haclient uid=hacluster
改为
respawn root /usr/lib/heartbeat/ipfail；
apiauth ipfail gid=root uid=root
就可以了，ipfail进程可以启动了，而且再也不会出现下面的令人郁闷的错误信息了。

附带的/var/log/ha-log报错信息。

heartbeat的respawn可以检测ipfail等，但是respawn检测ldirectord还是不行，每次ldirectord的rc=0或1都导致heartbeat重启ldirectord，结果ldirectord都关闭了，没有启动。虽然linux稳定但是也用heartbeat热备，ldirectord稳定也需要监控把？？查查watchdog的监控！！

如果是hb2.0以上的话，完全可以

配制好/etc/ha.d/haresources和ha.cf后，调用 /usr/lib/heartbeat/haresources2cib.py

可以生成 /var/lib/heartbeat/crm/cib.xml

就可以对apache的状态进行监测了。

如果不行，可以运行hb_gui，为apache资源添加一个monitor
