Change vault configuration

  1. Copy client certificates FIRST.NODE.DNS.p12 and FIRST.NODE.DNS-ws-sndbx.p12 from /opt/workfusion/apps/webapps/wf_sec_storage on first node to all others nodes

  2. Edit file /opt/workfusion/apps/webapps/tomcat/conf/workfusion.properties on the second node and change the following properties. They should be the same as on the first node

    Property name
    wf.resource.url
    s3.endpoint.url
    s3.bucketURL
    secure.storage.safe.customer.default
    secure.storage.safe.internal
    secure.storage.serverApi
    secure.storage.client.certificate
    secure.storage.username.customer
    datasource.wf.xaProperties.url
    datasource.ds.xaProperties.url

  • Edit file /opt/workfusion/apps/webapps/tomcat/conf/workspace.properties on the second node and change the following properties. They should be the same as on the first node

    Property name
    dataSource.url
    web.resourceUrl
    secure.storage.safe.customer.default
    secure.storage.safe.internal
    secure.storage.serverApi
    secure.storage.client.certificate
    secure.storage.username.customer

  • Edit file /opt/workfusion/apps/webapps/tomcat/conf/workspace-sandbox.properties on the second node and change the following properties. They should be the same as on the first node

    Property name
    dataSource.url
    web.resourceUrl
    secure.storage.safe.customer.default
    secure.storage.safe.internal

    secure.storage.client.certificate
    secure.storage.username.customer

  • Update hazelcast.network.tcpip.members property with a list of all nodes ip addresses

    1. Log in to the first node via SSH.

    2. Change the working directory:

    cd /opt/workfusion/apps/webapps/wf_sec_storage/

    1. Create a file ha-members.properties with the following content:

    hazelcast.network.tcpip.members=FIRST_NODE_IP,SECOND_NODE_IP

    1. Upload property to the secure storage.

    /opt/workfusion/lib/java/bin/java -jar loader-security-properties.jar connectionProps.json ha-members.properties

    • Update Tomcat configuration

      portSpecify the port for tomcat cluster. Should be different from Tomcat Server port. Should be the same on all nodes. Should be different from Connector port (Connector port can be found in ****/opt/workfusion/apps/webapps/tomcat/conf/server.xml****)
      Memberportuse the same value as a receiver port
      hostip address of the next application node
      uniqueIdShould be unique on each node

    1. Copy license.properties file (obtain from first node) to the location specified as LICENSE_PATH in environment.conf file

    2. Restart tomcat on each node

    Update Nginx configuration on all nodes

    • Edit the /opt/workfusion/apps/nginx/etc/upstream/wf-ha file.

    • Add each node to to the bottom of upstream wf_ha section of this file using the following format:

    server APP_FQDN:TOMCAT_PORT;

    upstream wf_ha {
    sticky;
    server onprem-v2-623-8.4.1-wf1.workfusion.com:13080;
    server onprem-v2-623-8.4.1-wf2.workfusion.com:13080;
    }
    • Edit the /opt/workfusion/apps/nginx/etc/upstream/ws-ha file.
    • Add each node to to the bottom of upstream ws_ha section of this file using the following format:

    server APP_FQDN:TOMCAT_PORT;

    upstream ws_ha {
