mysql-php problem on RHL7

Hello, I have installed Red Hat Linux 7 and during the instalation proces I chose to install php4 and mysql. After instalation I have added php-mysql support using rpm file. Both MySQL and PHP seems to work fine (mysqld is running,mysql client work good and php parse *.php files) but when I try to connect script with database using mysql_connect(...), I receive following error message: Warning: MySQL Connection Failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111) ... I have also tried to put complete path (localhost:port:/var/lib/mysql/mysql.sock...) in mysql_connect( ) function but it didn't solve the problem. When I try to edit file mysql.sock I receive error message. Please help me. Dragan Dinic, Serbia
