Notification Server in Seafile cluster¶
In Seafile Pro edition, the notification server is the same as community edition notification server.
If you enable clustering, You need to deploy notification server on one of the servers. The load balancer should forward websockets requests to this node. The notification server configuration corresponding to each node of the cluster is as follows.
The notification server configuration should be the same as in community edition:
[notification]
enabled = true
# the ip of notification server.
host = 192.168.1.134
# the port of notification server
port = 8083
# the log level of notification server
log_level = info
# jwt_private_key is used to generate jwt token and authenticate seafile server
jwt_private_key = M@O8VWUb81YvmtWLHGB2I_V7di5-@0p(MF*GrE!sIws23F
You need to configure load balancing according to the following forwarding rules:
- Forward
/notification/ping
requests to notification server via http protocol. - Forward websockets requests with URL prefix
/notification
to notification server.
Here is a configuration that uses haproxy to support notification server, and haproxy version needs to be >= 2.0. You should use similar configurations for the other load balancers.
#/etc/haproxy/haproxy.cfg
# Other existing haproxy configurations
