I've installed ZSCM in centos 5.2. But I can't connect to Mysql server. And I got this error message in zend_server_ui.log
"ERR (3): Failed in database connection check
Exception of type 'DatabaseManager_Exception': Could not connect to the database at 192.168.56.112:3306 (SQLSTATE[HY000]  Can't connect to MySQL server on '192.168.56.112' (4))"
What error is it? and how can we solve that problem?
