Difficulties with YUM / mysql

I am trying to install mysql v5.1 on CentOS 5.2

I have never used YUM before and now I am in a mess.

Originally, until half an hour ago, I was running mysql (server) version 5.0.45-7.el5.

Want to upgrade to v.5.1.

Never done this before, or anything like it. I backed up all databases, stopped the mysqld service and typed:

# yum install MySQL-server-5.1.60-1.glibc23.i386.rpm

YUM said:

Error: mysql conflicts with MySQL

That seemed fair enough since the two versions are not compatible. So, I typed:

# yum remove mysql

That was fine.

Finally I tried again to install the new mysql version:

# yum install MySQL-server-5.1.60-1.glibc23.i386.rpm

and got the messages:

warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 5072e1f5
Public key for MySQL-server-5.1.60-1.glibc23.i386.rpm is not installed

I can't start the mysql daemon and

# yum list MySQL

shows no trace of the package.

I tried a localinstall from a downloaded rpm file and got exactly the same result.

I hope this is something simple - it's a production server and I have to get it going again!

I tried reinstalling an older version of mysql, but not sure whether that has worked either - I can't start the mysqld service.

As this is marked as 'solved', do you mind sharing how you solved it?

This is, by the way, a duplicate of which has more replies.

It does not sound like you had a redundant system to fall back on, so I hope you've learned an important lesson: do not mess with production servers till you know exactly how.
