Autoscaling and High Availability
Enterprise listens to all interfaces on ports as specified above (8120 by default, optionally 8120 through 8120+number of cores) to facilitate sending all traffic from a load balancer (that terminates TLS) such as an ELB or HA Proxy server, while Pro listens to localhost only.
Remember to configure Redis on a separate host (replicated and Elasticache work well) using the HA/Redis tab of the admin dashboard.
Multi-core Startup Script
Run a single instance of Userify for each processing core on each node:
#! /bin/bash # Userify multi-core startup script SERVER_PATH="/opt/userify-server" SERVER_COMMAND="$SERVERPATH/userify-server" # adjust number of cores as appropriate numcores=$(grep processor /proc/cpuinfo |wc -l) cd "$SERVER_PATH" for port in $(seq 8120 $((numcores+8119))) do (while true do echo "Starting Userify on $port and sending output to syslog." sudo "$SERVER_COMMAND" server $port | \ logger --priority local2.info --tag userify-server 2>&1 # when the server exits, sleep 3 seconds before restarting sleep 3 done) & # slow down startup between each core sleep 10 done echo echo "Be sure to add proxy_pass statements for ports shown above."
