I can't set up a Neo4j cluster -

i have neo4j server works fine but, when tried set cluster can't figure out why not work.

in order make cluster work, seems need uncoment following lines:

ha.server_id = 3 ha.initial_hosts =192.168.1.93:5001,192.168.1.91:5001 dbms.mode=ha 

but when so, got error in logs file db load.

this neo4j.conf file

thank you

first of all, if error on startup, least quote here, otherwise there's not can it.

regarding configuration, there's @ least 1 mistake: participate in cluster other hosts using ip addresses such 192.168.1.93 , 192.168.1.91, need set host communicate on same network, not on loopback (i.e. 127.0.0.1) other hosts cannot connect to.

if host has e.g. 192.168.1.93, that's need use:

ha.initial_hosts=192.168.1.93:5001,192.168.1.91:5001 ha.host.coordination=192.168.1.93:5001 ha.host.data=192.168.1.93:6001 

however, if host has 192.168.1.92, need add ha.initial_hosts (which same on hosts, noted in comment, , not list of other hosts):

ha.initial_hosts=192.168.1.93:5001,192.168.1.92:5001,192.168.1.91:5001 ha.host.coordination=192.168.1.92:5001 ha.host.data=192.168.1.92:6001
