Changing a browsing server to an authoring one

Question

Initially, there is no cluster defined in the environment and thus, there were no "Authoring" servers. How to change a "Browsing" server to an "Authoring" one without reinstalling a Jahia instance?

Answer

An "Authoring" server is a Jahia cluster node.

This is possible to redefine a server as a cluster node after the Jahia installation.
Some modifications are needed in the jahia.node.properties file under: [Jahia]/digital-factory-config/jahia

As an "Authoring" server has to be defined, a "Processing" one is also needed and it has to be unique.

The procedure is the following one:

Update the jahia.node.properties file of the server which will be the "Processing" server:

Uncomment following lines

#cluster.activated = false to get: cluster.activated = true
#processingServer = true to get: processingServer = true

DO NOT uncomment:

#cluster.tcp.bindPort = 7870

Update the jahia.node.properties file of the server which will be the "Authoring" server:
Uncomment:

#cluster.activated = false to get: cluster.activated = true
#processingServer = true to get: processingServer = false
#cluster.tcp.bindPort = 7870 to get: cluster.tcp.bindPort = 7871

Then restart both nodes.
