Thread:Project:Support desk/MediaWiki Building failure——Mysql connection issue

Hi, everyone Today i have try to build the mediawiki server. It takes me a whole day, now i can access the mediawiki building home web, so i think the apache and php can work normally. but i was holded at the configuration of database.

My Sofeware details:
 * OS - linux 2.6.18
 * Apache - http2.2.3-31
 * php - 5.5.3
 * mysql - 5.0.77

The error prompted: Or
 * Database host:192.168.2.102
 * Database: wikidatabase
 * DBUser:root
 * DBPassword: ***
 * DB connection error: Permission denied (192.168.2.102).
 * Database host:localhost
 * Database: wikidatabase
 * DBUser:root
 * DBPassword: ***
 * DB connection error: DB connection error: mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file (localhost).

I must carify that i can oper mysql in the local server, and port 3306 was opened. I think it may be php or mysql's issue. Anybody help me?
