# Introductions Planning to connect to multiple Cluster at once from a single server? heres the plan... - Cluster 1 - c1-node-1 - c1-node-2 - c1-node-3 - Cluster 2 - c2-node-1 - c2-node-2 - c2-node-3 - Cluster 3 - c3-node-1 - c3-node-2 - c3-node-3 # Prerequisite - install the mysqlrouter as usual - do not bootstrap anything yet - set your /etc/hosts files containing all the relevant servers - always set different base port so it doesnt clash to each other - always set different https port so it doesnt clash to each other # Installation - run the command for bootstrapping the servers ``` ##boostrap the Cluster 1 $> mysqlrouter --boostrap <boostrap-user>@<c1-node-1> -d <c1-conf-directory> --user=mysqlrouter --conf-base-port=6446 --https-port=18443 ##boostrap the Cluster 2 $> mysqlrouter --boostrap <boostrap-user>@<c1-node-2> -d <c2-conf-directory> --user=mysqlrouter --conf-base-port=7446 --https-port=28443 ##boostrap the Cluster 3 $> mysqlrouter --boostrap <boostrap-user>@<c1-node-3> -d <c3-conf-directory> --user=mysqlrouter --conf-base-port=8446 --https-port=38443 ``` - once the boostrap is done, you can start using the nohup command to make it run on the background ``` $> nohup mysqlrouter -c <c1-config-directory> & $> nohup mysqlrouter -c <c2-config-directory> & $> nohup mysqlrouter -c <c3-config-directory> & ``` - to check your setup is working just check the `ps` command ``` ps -ef | grep mysqlrouter ``` - the command above should show 3 of the instances of mysqlrouter processes has been successfully started.
