When there is more than one master does each master need a unique fixed port number or should all of the fixed port numbers be the same. Is the fixed port number used in HA setups? 0 Denys Digtiar May 04, 2017 07:29 Hi Mark, No, it should not, unless it conflicts with any other service on the host. We recommend unique ports. Fixed port is necessary largely to support firewalls. In HA setup we recommend avoiding proxying the JNLP port with a reverse proxy but configure Jenkins in such way that enables direct communication of agents to the primary node. Please refer to How to set-up a CJP HA environment with HA Proxy. If you experience any issues with connection between Operations Center and Client Master please consult the Troubleshooting section of the knowledgebase Best regards, Denys 0 Please sign in to leave a comment.
