For Serviceaide Automation On-Premise Agent deployment, the following components should be installed on the on-premise server:

  • itas_mule_adaptor

  • itas_connectors

  • itas_service_bus

  • sa_tunneling_service

  • mule_run

Use 'lumauser' to execute all the docker container, deployment scripts, and all the docker commands instead of sudo user. 

Pre-Deployment Actions

Perform the following Pre-deployment actions:

  1. Set up artifacts

    1. Download and transfer itas-deployment-2.0.0-onprem.zip to /platform/deployment directory and unzip

      cd /platform/deployment unzip itas-deployment-2.0.0-onprem.zip -d itas-deployment-2.0.0-onprem

2. Set up "master.properties"

  1. Populate master.properties file located under /platform/deployment/itas-deployment-2.0.0-onprem/itas-deployment-2.0.0/deploy directory.

  2. Configure system ulimits in file /etc/security/limits.conf

    centos soft nproc 16384 centos hard nproc 16384 centos soft nofile 65536 centos hard nofile 65536 lumauser soft nproc 16384 lumauser hard nproc 16384 lumauser soft nofile 65536 lumauser hard nofile 65536 root soft nproc 16384 root hard nproc 16384 root soft nofile 65536 root hard nofile 65536

  3. Login to dockerhub using the below command:

    docker login https://registry-1.docker.io -u serviceaideindia # use the dockerhub password provided separately

  4. Setup directory structure

    sudo mkdir -p /platform/data/logs/itas/itas_mule_adaptor sudo mkdir -p /platform/data/logs/itas/itas_db_migration sudo mkdir -p /platform/data/logs/itas/itas_service_bus sudo chmod -R 777 /platform/data/logs/itas sudo mkdir -p /platform/data/attachment_store/itas sudo mdir -p /platform/data/servicebus_store/itas sudo chown -R 1000:1000 /platform/data/servicebus_store/itas sudo chown -R 1000:1000 /platform/data/attachment_store/itas

  5. Install mule_run (one-time activity, not required if you are upgrading / already have mule_run installed)

    cd /tmp sudo wget -q https://repository.mulesoft.org/nexus/content/repositories/public/org/mule/distributions/mule-standalone/3.9.0-hf2/mule-standalone-3.9.0-hf2.zip sudo unzip -qq mule-standalone-3.9.0-hf2.zip sudo mv mule-standalone-3.9.0-hf2 /platform/data/mule_run sudo chown -R 1000:1000 /platform/data/mule_run

In Master.properties file, the following properties are populated from your Automation tenant:

  • SA_TUNNELING_TENANT_EXTERNAL_ID - Populate your Automation Tenant External ID here.

  • SA_TUNNELING_APPLICATION_IDENTIFIER - Add the Execution Agent External ID here.

  • SA_TUNNELING_SECRET_KEY - Copy the On-premise Execution Agent Key here.

The keys are available on Automation → Execution Agent screen. Most of the properties on the file are self-explanatory. In case of any issue, please contact Serviceaide Support.

Start installation

Execute the below commands to start the installation:

cd /platform/deployment/itas-deployment-2.0.0-onprem/itas-deployment-2.0.0/deploy chmod +x onprem_stack.sh ./onprem_stack.sh deployall

Post Deployment Actions

Run the below command to clean up older unused volumes, images, etc after deployment.

#run command to delete all the unused docker images (This command will not delete docker images that are in use) docker rmi -f $(docker images | awk '{ print $3 }') > /dev/null 2>&1 #cleanup unsed volume, cache etc. docker system prune To check logs sudo tail -f `docker inspect --format='{{.LogPath}}' itas_muledb_migration`

Troubleshoot Errors

  1. If we get the below "permission denied error" : Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.37/containers/redis/stop: dial unix /var/run/docker.sock: connect: permission denied.

    [lumauser@lumatrialweb01 deploy]$ docker ps --> If permission denied comes then execute below command. [lumauser@lumatrialweb01 deploy]$ sudo setfacl -m user:lumauser:rw /var/run/docker.sock [lumauser@lumatrialweb01 deploy]$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES [lumauser@lumatrialweb01 deploy]$ docker login (Enter docker credentials)

     

  • Ensuring that if the deployment is completed or not :   
     Whenever we enter "Docker ps" command then we can see the status of the containers, If any container's status is less than 1 minute then focus on that and wait 1 or 2 minutes and issue again the same 'docker ps' command , if we see the same container's status is less than a minute then we can ensure that there will be some issue and later we can go ahead with "docker logs [container_name]"
