    Default Mysql could not be started on Pentaho 3.7/linux

    Hello Guys,

    I installed Pentaho 3.7 on a linux box. I didnt really change or try anything, sticked with the defaults. It was running fine for a couple days. Then I tried restarting the server using the ctlscript under Pentaho folder.

    It returned error saying cannot restart mysql... and these are the logs from mysqld file under mysql

    110315 17:53:34 mysqld_safe mysqld from pid file /home/pentaho/pentaho/mysql/data/ ended
    110315 17:59:18 mysqld_safe Starting mysqld.bin daemon with databases from /home/pentaho/pentaho/mysql/data

    Hi Praneeth,

    I checked with one of our MySQL gurus and it may be file permissions. If that doesn't work it might be something with user permissions. If that fails, you may want to resinstall MySQL.

    You may want to check with the MySQL forum to get a better understanding of the error.
    The best thing about a boolean is even if you are wrong, you are only off by a bit.

    Did you run 'mysql_upgrade', as was suggested by the logs?
