     Trying to set up APS controller database... Attempting to check APS db connection via ODBC, using /usr/bin/isql (empty output is good) 
    [ISQL]ERROR: Could not SQLConnect 
    Failed, rc = 1.

  1. Check that the MySQL server is running:

    # /etc/init.d/mysqld status
  2. Check that the MySQL server is accepting connections via TCP IP:

    # mysql -h -P 3306 -uadmin -p`cat /etc/psa/.psa.shadow`


If the MySQL server is stopped, it should be started with the following command:

    # /etc/init.d/mysqld start

The MySQL server may not be accepting connections via TCP IP because of your firewall settings, network link or MySQL server settings. For the MySQL server settings, you can check the /etc/my.cnf folder for the "skip-networking" parameter. If this parameter is present, then the MySQL server will not accept network connections via TCP. To enable TCP connections, comment on the "skip-networking" parameter by adding the "#" character ("#skip-networking"). After adding the character, restart the MySQL server by the following command:

    # /etc/init.d/mysqld restart
