Hello! I am trying to set up an active/active OpenSIPS pair in AWS.
The AWS set up is two OpenSIPs (V3.4.12) running on EC2 instances in two different availability zones. There is then a network load balancer (NLB) in each availability zone that distributes traffic to the two OpenSIPs nodes. I am trying to set up dialog sharing between the two nodes. The cluster appears to be healthy: * both nodes are in cluster 1 with flag set to `seed`. * opensips-cli -x mi clusterer_list_cap shows dialog-dlg-repl / state Ok / enabled Yes * opensips-cli -x mi clusterer_list – shows other node with link_state up, state enabled. My test to make a call through node 1, kill node 1, end the call with the BYE then going through node 2. When I try this, node 2 isn’t finding the dialog. If I run dlg_list during the call (before killing node 1) the dlg is present on node 1 but not node 2. So it looks like the dialog replication isn’t working. The dialog clustering manual suggests reading https://blog.opensips.org/2018/03/23/clustering-ongoing-calls-with-opensips-2-4/ which references dlg_sharing_tag which has since been deprecated. I don’t think I need tags, though potentially that’s where I’m going wrong. I’ve been down a few rabbit holes looking at out of date manuals for some of the modules! The relevant config for node 1 is as follows: loadmodule "proto_udp.so" socket = udp:10.4.60.11 # NLB 1 socket = udp:10.4.60.11 as 10.4.38.178 # NLB 2 socket = udp:10.4.60.11 as 10.4.63.19 # Tried setting tag public here but didn’t help #### DIALOG module loadmodule "dialog.so" modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "default_timeout", 600) # 6 hours timeout modparam("dialog", "db_mode", 2) modparam("dialog", "db_url", "mysql://opensips:[email protected]/opensips") modparam("dialog", "dialog_replication_cluster", 1) ### CLUSTERING socket = bin:10.4.60.12:5566 # bin listener for OpenSIPS clustering loadmodule "proto_bin.so" loadmodule "clusterer.so" modparam("clusterer", "db_mode", 1) modparam("clusterer", "db_url", "mysql://opensips:[email protected]/opensips") modparam("clusterer", "my_node_id", 2) # node_id for OpenSIPS 1 route { … # handle the initial INVITE to create a dialog if (is_method("INVITE")) { … if ( !create_dialog("B") ) { send_reply(500,"Internal Server Error"); exit; } } Any suggestions on how to debug or glaring omissions would be very helpful.
