UNIX for Dummies Questions & Answers

I had mysql installed on my unix system but for some reason it wasn't starting up when I changed the datadir in my.cnf located in etc. It was saying that there's some permission problem. But, I double checked everything and everything looked fine. I wanted to install the latest version of mysql, so I removed the existing version.

Now I just downloaded the server, client and shared community libraries of mysql and installed them using rpm. Now, I don't find a my.cnf file nor does this command: "/etc/init.d/mysqld start" work. And here's the messages:

Code:

root# /etc/init.d/mysqld status
bash: /etc/init.d/mysqld: No such file or directory
root# mysqld restart
bash: mysqld: command not found

But when I type mysql it is running and gives me a prompt too and as far as I remember, it shows me the databases in /var/lib/mysql. Can someone help me out please?

If /etc/init.d/mysqld cannot be found, it's not registered as a service.

Take a look at something like this to see if this helps:

Code:

$ chkconfig --add mysqld

Thanks but it says chkconfig command not found... When I do a man on the command, it shows some help but still it says that the command is not found... Also when I'm trying to run a php file that involves connecting to a database, it says:

Code:

PHP Fatal error:  Call to undefined function mysql_connect()

As far as the information that I found out goes, I have to install php-mysql extension or something. My PHP version is 5.0.4 and MySQL is 5.1.22 and I don't know where to and how to install this extension...

Not posting the details of your OS and distribution version does not make helping any easier

I am so sorry. When I typed uname -a, this is what I get:

Code:

Linux  2.6.11-1.1369_FC4smp #1 SMP Thu Jun 2 23:16:33 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux
