i keep getting this error message when trying to install smf 1.1.6 on my website:

"Cannot connect to the MySQL database server with the supplied data.

If you are not sure about what to type in, please contact your host.

Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)"

could it be from incorrect settings in my php.ini file?

this is what it currently is:

register_globals = off
allow_url_fopen = off

expose_php = Off
max_input_time = 60
variables_order = "EGPCS"
extension_dir = ./
upload_tmp_dir = /tmp
precision = 12
SMTP = relay-hosting.secureserver.net
url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset="

[Zend]
zend_extension=/usr/local/zo/ZendExtensionManager.so
zend_extension=/usr/local/zo/4_3/ZendOptimizer.so


any help would be appreciated.
Thanks
