Running startup.bat and startup.sh does not work

Last Updated: Jan 17, 2018

This problem may occur due to several reasons. Perform troubleshooting based on the prompted error message.

  1. Error message: Java version not supported, must be 1.6 or 1.6+.

    Solution:

    Check whether Java is properly installed. If Java is not installed, install Java 1.6 or a later version.

  2. Error message: "Unable to start embedded Tomcat servlet container" or "Tomcat connector in failed state".

    Solution:

    Check whether port 8080 is in use. If the port is being used by another program, stop the program and execute the startup script. The specific steps are as follows:

    • Windows

      1. Open the CMD window and run netstat -aon|findstr "8080". Record the last column of numbers in the queried data, namely the process ID (PID), for example "2720".
      2. Run tasklist|findstr "2720". The program corresponding to the current PID, for example javaw.exe, is displayed.
      3. Run taskkill /PID 2720 /T /F.
      4. Start the lightweight configuration center again.
    • Linux

      1. Run netstat -antp|grep 8080. The PID of the program that uses port 8080 is displayed, for example "2720".
      2. Run kill -9 2720.
      3. Start the lightweight configuration center again.
  3. Error message: Caused by: java.net.UnknownHostException: iZ25ax7xuf5Z

    Solution:

    iZ25ax7xuf5Z indicates the current host name. Check whether the current host IP address and name are configured in /etc/hosts. If not, configure them, for example, 192.168.1.10 iZ25ax7xuf5Z.
