我所做的唯一改变是
$dbHost = <hostname>
至
$dbHost = <ipaddress>
现在它给了我连接错误。
错误:
Database Connection Error
A failure occurred attempting to connect to the database.
This could be caused by a temporary network failure, but it's more likely that this is the result of incorrect database connection parameters specified at the time WebEvent was installed.
