Cannot connect to MySQL server - include/config.php (solved)

[runlikeanantelope]

I get this error when browsing to my http://server/cacti

Cannot connect to MySQL server on 'localhost'. Please make sure you have specified a valid MySQL database name in 'include/config.php'.

I'm not sure this command in the instructions took because of the message it sends after it. Is it because the version of MySQL that I am using takes different commands?

'rehash' to get table and field completion, but startup
and reconnecting may take a longer time. Disable with
--disable-auto-rehash.
-A, --no-auto-rehash
No automatic rehashing. One has to use 'rehash' to get
table and field completion. This gives a quicker start of
mysql and disables rehashing on reconnect. WARNING:

PAGER. Valid pagers are less, more, cat [> filename],
etc. See interactive help (\h) also. This option does not
work in batch mode.
-p, --password[=name]
Password to use when connecting to server. If password is
not given it's asked from the tty.

OK - I ran that command as two separate commands and it took, but I still get the same error on the webpage:

[root@linuxmcarey cacti]# /usr/bin/mysql --user=root --password=rootpw cactidb < cacti.sql
[root@linuxmcarey cacti]# chown cactiuser rra/ log/

[runlikeanantelope]

OK - I ran through the Configure MySQL section a 2nd time and it worked this time. If I have other issues, I'll open another forum post.

Thanks for your patience with a newbie

Check that your disks have not run out of space (df -H), that the process is running (ps -uaxw | grep mysql) and try telneting to the port (usually 3306) to see if it is accepting connections.
In my case I had run out of disk space, corrected it, rebooted and everything was OK.
