Remarks

client1

1 x controller

N x driver

N indicates the number of COSBench drivers running on the client. In this document, N is 20.

Starting COSBench

Start the COSBench drivers and controllers separately.

  1. Download the COSBench package and save it to the /home directory of each client.

    Download address: https://github.com/intel-cloud/cosbench/releases/download/v0.4.2.c4/0.4.2.c4.zip

  2. Install dependencies on each client.
    1
    		 
    yum -y install java curl
  3. Decompress the package on each client and go to the directory generated after the decompression.
    1
    		 
    unzip /home/0.4.2.c4.zip && cd /home/0.4.2.c4/
  4. Start 20 COSBench drivers on each client.
    1
    		 
    sh start-driver.sh 20 127.0.0.1 19188

    In the preceding command:

    • The value 20 indicates that 20 drivers are started.
    • 127.0.0.1 indicates that the drivers are started on the local client.
    • 19188 indicates the port number of a driver. The port numbers start from 19188 and increase by an increment of 100.
  5. Modify the controller.conf file.
    1
    		 
    vi conf/controller.conf

    Modify the file as follows:

    The COSBench controller and 20 COSBench drivers have been started on the client.

    In the controller.conf file:

    • drivers = 20 indicates that the controller controls 20 drivers on the client, and the IP addresses and port numbers of the 20 drivers are added.
    • 192.168.3.194 is the IP address of the client.
  6. Disable the proxy on each client.
    1
    		 
    unset http_proxy && unset https_proxy
  7. On the COSBench controller node of the client, start the controller.
    1
    		 
    sh start-controller.sh
  8. Check whether the COSBench is started.

    In the browser, enter http://<cosbench-controller-IP>:<controller-port>/controller/index.html to access the controller node. If the following information is displayed, COSBench is started successfully.
