Multiple MySql versions

Hello,

Is it possible/stable to have two different MySql versions running on the same machine ?
Right now I have MySql 5.5 via custombuild.
But some software still requires 5.0.. -_-

I'm not planning on downgrading MySql back to the year 2003 for the ossec rootkit/etc checker, but it seemed like an interesting piece of software to secure a server.

Hello,

What software still requires 5.0 ? Does it connect straight to the database?

You best help would be :
http://dev.mysql.com/doc/refman/5.1/en/multiple-servers.html

as directadmin does not support multiple mysql.

Yes, for sure:

http://dev.mysql.com/doc/refman/5.0/en/multiple-servers.html

Are you sure that independent mysql 5.0 server is required? Or only libraries?

Note, PHP can be compiled against only one MySQL version, so you'll need probably to do a lot of manual work and as it was already mentioned by simba directadmin does not support multiple MySql installations.

okay, thanks you guys

I was doing these commands:

# wget... from directadmin file server
# chmod 755 /usr/lib64/libmysqlclient.so.15
# ldconfig

But that didn't get the job done..
When I tried to yum install that program, it was missing that exact limysqlclient.so.15 dependency.

When I forwarded this to the makers, they told me I needed to install that package.

So that got me confused thinking I'd need to install MySql 5.0

Why would a .so need to be executable?
