Starting Engine...........FAILED


#1

Hello, everyone!
By running ./grakn server start I got Storage and Queue start successfully, but failed to start the engine. My running environment is “Linux version 2.6.32.el6.x86_64, java1.8”, while 1.2.0 is the version of Grakn installer that I downloaded from GRAKN.AI . The massage in grakn.log shows "java.lang.RuntimeException: Couldn’t get PID of Grakn. Receive " is the only error massage I can find so far. I know there are topics similar to mine, but none of them helpful . Is there anyone who has any idea how to resolve it ?


Please report any error "java.lang.RuntimeException: Couldn’t get PID of Grakn. Received '"

Hi! Thank you for reporting the issue. Can you provide informations as outlined in this thread: Be sure to report any Grakn boot up issues!

Hi,ganesh, Thank you for respose. Here is the information:

  1. Grakn version: 1.2.0
    2.My operation: Red Hat Enterprise Linux Server release 6.5, Linux version 2.6.32.el6.x86_64
  2. I download Grakn from https://grakn.ai/ with the button “Dwonload 1.2”, and I get the installer “grakn-dist-1.2.0.tar.gz”.
  3. After get the installer, I unzip it using tar command, followed by starting command “./grakn server start”.
  4. “ls -la /tmp/*.pid” gives:
    -rw-r–r-- 1 root root 6 Apr 26 14:02 /tmp/grakn-queue.pid
    -rw-r–r-- 1 root root 5 Apr 26 14:02 /tmp/grakn-storage.pid
  5. “ps -ef | grep redis-server” gives:
    root 65742 1 0 14:02 ? 00:00:00 /root/grakn/services/redis/redis-server-linux 127.0.0.1:6379
    root 65976 5688 0 14:15 pts/13 00:00:00 grep redis-server
  6. “jps” shows:
    65984 Jps
