标题: 关于:MDaemon Server Cluster(群集) [打印本页] 作者: goxia 时间: 2005-3-2 11:31 标题: 关于:MDaemon Server Cluster(群集) 以下是ALTN官方和一个MD管理者的回答:<br>
1)MDaemon does not currently support Windows clustering, sorry.<br>
<br>
2)I actually have this working now with the cluster based on File Share,<br>
and Generic Windows Service. You need to separate your mail data from<br>
your application files (have c partition for OS, D for Mdaemon App, and<br>
M cluster drive for data such as user mail, public folders, etc...).<br>
Use replication with robocopy for your dat files, but maintain separate<br>
ini files for Mdaemon. You will need to use Mapped drives on each<br>
cluster member for the data since Mdaemon does not seem to want to play<br>
nice with UNC paths for data locations. Took a bit of trial and error<br>
to set up but it is all working now. Mdaemon is not cluster aware but<br>
the OS and File System are so it all works out. You can set a number of<br>
dependencies but the share and the generic service are sufficient. If<br>
the share fails, or the mdaemon service crashes there is a grace period<br>
to allow a restart to happen and then a fail-over to the other standby<br>
node. The IP and cluster name get transferred to the other node<br>
immediately and everything starts working again. Also make sure you set<br>
up the Network Service in Mdaemon as a Domain Account that has proper<br>
permissions on each node in your cluster. I just have 2 that share an<br>
attached RAID array which is also configured in cluster mode.<br>
Optionally, you can sit this behind a load-balancer for better HA.<br>

应该能做集群呀,我都做好了。<br>
但我对MD不太熟悉,不知道数据会不会同步,其实我也想找大家讨论一下,赶兴趣的,可以加我futucker2001@hotmail.com作者: goxia 时间: 2005-3-3 09:32 标题: re:可以把你的介绍一下给大家么? 可以把你的介绍一下给大家么?作者: U-Mail 时间: 2005-3-3 10:38 标题: re:md是说软件本身不支持集群,不代表没有集... md是说软件本身不支持集群,不代表没有集群解决方案.我以前是试过的,完全没问题.<br>
<br>
以前给一家公司做方案,公司粉有钱,而且要求也很高,于是就用两台服务器和RAS,然后用ROSE HA做的集群,效果很好.作者: hzmark 时间: 2005-3-4 00:11 标题: re:我个人觉得,MD应该是支持做集群的,要不... 我个人觉得,MD应该是支持做集群的,要不然,他们真的没法再卖了:)作者: hzmark 时间: 2005-3-4 18:50 标题: re:电源烧了,不太明白楼上的意思?服... 电源烧了,不太明白楼上的意思?<br>
<br>
服务器电源烧了,双机软件会做切换呀,切换到另外一台服务器上,MD照常运行呀,有什么关系?<br>
<br>
希望与楼上电话交流057128920876<br>

关键是全自动的群集,也就是说,当nodea出现故障,nodeb继续工作,并且MD也自动工作。<br>
使用普通的方法,能够保障用户目录实现群集,但是账号设置却很难。因为账号和其他设置使用的文件方式保存,我们需要将MD安装在*享盘中,而nodea和nodeb同时开启的时候,只有一个节点有控制权,那么必然导致另外一个节点的MD运行失败。所以还有需要考虑解决的问题。作者: cfang 时间: 2005-3-7 14:46 标题: re:留个名,下次好找 留个名,下次好找
