# How-to for Eole 2.6.2 (using this repo dico and templates)
|
||||
|
||||
### FIXME
|
||||
Start with 3 fresh eolebase 2.6.2 instancied.
|
||||
|
||||
One for the Clustter Leader, another for the cluster Node another for the Arbitrator, the arbitrator can be replaced by another node.
|
||||
|
||||
The order is very important, Never configure a Node before the Leader ! The Leader must be the first one.
|
||||
|
||||
## Add the Cadoles repository on all the nodes and the Leader
|
||||
|
||||
GenConfig [Mode Expert] -> Dépôts Tiers

|
||||

|
||||

||||

|
||||
|
||||

## Reconfigure the Nodes !
|
||||
Run reconfigure command on each node one by one.
|

|
||||
## Configure the Arbitrator if needed !
|
||||
|
||||
If you have only 2 nodes you need to setup an arbitrator, for this follow the tutorial in the eole-galera-arbitrator project page https://forge.cadoles.com/Cadoles/eole-galera-arbitrator
