ejabberd Clustering with master Slave and Master Master not avoid single point of failure -

-

whenever master gets down in ejabberd cluster slave not able process request. follow tutorial : http://chadillac.tumblr.com/post/35967173942/easy-ejabberd-clustering-guide-mnesia-mysql , try join_node() , join_as_master() also. not working. cluster working , i used mysql database separate database both node. tried join master slave , master master method. both not working avoid single point of fauilure. is necessary synchronize slave , master mnesia database? please 1 can me in this...

there no single point of failure ejabberd if configure right way. there no such thing master-slave in ejabberd. ejabberd master-master , if configure join_clustercommand described in official ejabberd documentation: http://docs.ejabberd.im/admin/guide/clustering/

you need configure other services redundant well: - load balancer - mysql

once done, not see can see point of failure. if node has go down, service keeps on working fine users connected on other nodes , 1 have been disconnected can reconnect fine on of remaining node.

if means if stop both nodes , try start first stopped, normal behaviour of mnesia distributed database. duplicate question answered here: ejabberd clustering, slave doesn't work when master goes down

note: blog post pointing obsolete.
