Starting BEs

This section describes how to deploy and use the Doris instruction optimization feature.

1. Deploy the Doris instruction optimization by referring to Doris Instruction Optimization Deployment Guide.
2. Stop all BEs on all nodes in the cluster.

   1	sh /opt/tools/installed/apache-doris-2.1.2-bin-arm64/be/bin/stop_be.sh

3. Use the compiled /opt/tools/installed/doris-2.1.2-rc04/be/output/lib/doris_be to replace all doris_be files in /opt/tools/installed/apache-doris-2.1.2-bin-arm64/be/lib/doris_be of all BEs in the cluster.

   1	cp /opt/tools/installed/doris-2.1.2-rc04/be/output/lib/doris_be /opt/tools/installed/apache-doris-2.1.2-bin-arm64/be/lib/doris_be

4. Start all BEs in the cluster.

   1	sh /opt/tools/installed/apache-doris-2.1.2-bin-arm64/be/bin/start_be.sh --daemon

5. Check the BE startup status by following steps 1 and 3 in the section "Adding a BE to the Doris Cluster."
