Restoring SSL for the HA Module

Scenario

This section describes how to restore SSL for the HA module of DBService in the cluster where DBService is installed.

Prerequisites

SSL has been enabled for the HA module of DBService.

Check whether SSL is enabled for the HA module of DBService.

Check $BIGDATA_HOME/FusionInsight_BASE_x.x.x/install/FusionInsight-dbservice-2.7.0/ha/module/hacom/conf/hacom.xml. If the file contains <hadataprotocol value="ssl"></hadataprotocol>, SSL is enabled.

Procedure

  1. Log in to the DBService node where SSL needs to be restored as user omm.
  2. Run the following commands to restore the DBService configuration file hacom_local.xml:

    cd $BIGDATA_HOME/FusionInsight_BASE_x.x.x/install/FusionInsight-dbservice-2.7.0/ha/local/hacom/conf/

    cp hacom_local.xml $BIGDATA_HOME/tmp/

    cat hacom_local.xml | grep "ssl>" -n | cut -d':' -f1 | xargs | sed 's/ /,/g' |xargs -n 1 -i sed -i '{}d' hacom_local.xml

  3. Run the following commands to restore the DBService configuration file hacom.xml:

    cd $BIGDATA_HOME/FusionInsight_BASE_x.x.x/install/FusionInsight-dbservice-2.7.0/ha/module/hacom/conf/

    cp hacom.xml $BIGDATA_HOME/tmp/

    sed -i 's#<hadataprotocol.*#<hadataprotocol value="udp"/>#g' hacom.xml

    sed -i 's#<rpcsupportssl.*#<rpcsupportssl value="true"/>#g' hacom.xml

    $BIGDATA_HOME/FusionInsight_BASE_x.x.x/install/FusionInsight-dbservice-2.7.0 is the installation directory of DBService. Modify it based on the upgrade environment.

  4. Go to the $BIGDATA_HOME/FusionInsight_BASE_x.x.x/install/FusionInsight-dbservice-2.7.0/ha/module/hacom/script/ directory and run the following command to restart the HA process:

    ./stop_ha.sh

    ./start_ha.sh

  5. Run the following command to obtain the PID of the HA process:

    ps -ef |grep "ha.bin" |grep DBSERVICE

  6. Run the following command to check whether the protocol is changed to TCP:

    netstat -nap | grep pid | grep -v unix
    • If yes, no further action is required.
    • If no, contact O&M support.
    [omm@host03]\>netstat -nap | grep 49989
(Not all processes could be identified, non-owned process info 
 will not be shown, you would have to be root to see it all.)
