Best way to install multiple mysql server on Linux - mysql

I am having CentOS release 4.7 (Final) which already have mysql installed on it.
I want to use this but do not have credentials to create database and all..
Also it is having some very important databases so I can not even reset password.
I am looking for a way to install new instance of mysql server on this machine.
could anyone please help me in this ?
Thanks in advance.

I guess this page http://dev.mysql.com/doc/refman/5.0/en/multiple-data-directories.html documents the question completely

How do I restart a MySQL local instance in MySQL workbench?

I've recently gotten into databases for a class I'm currently in, and I need a little bit of help. I've managed to create a database, and even populate a table with data which I was then able to grab from a node.js project I've made in Atom. Wonderful! When I went to shut it down, all seemed normal but now it won't restart. As in, when I'm in the homepage section of MySQL I double click the local instance I made(I can only assume this is opening the connection to the local instance where my database is stored) but it won't start up. I don't know what I'm doing wrong. Here is an image of the error I'm getting. I can only assume it's because the actual server isn't on but I don't know how to turn it on.
Any help is much appreciated!
Thank you!
As according to the users ikiK, P.Salmon, and Y4glory the issue I was having was that I wasn't actually turning on the server. I was able to do so by going through my Window's Services application, finding the MySQL server and starting it there instead of trying to do so through the workbench.
Once again, thank you to those who commented as that was really helpful!!
I have tried every other way mentioned here and other related posts, but it did not solve my problem, the service just wont start, but the below approach with the mysql-installer did.
For this to work you need to have your installer which you have used earlier to install MySql.
Start your windows mysql installer. For me it was "mysql-installer-community-8.0.20.0"
Then remove/uninstall the SQL Server and remove all configurations
Manually delete the SQL Server folder from "C:\Program Files\MySQL\MySQL Server 8.0."
Start your mysql installer again and install the SQL Server again
You can check now that the MySqL Server has started.
Hope it helps someone.

MYSQL - Connect MYSQL Workbench to a MYSQL server on localhost

I know the question I am about to ask is a very stupid once but I am new to MYSQL so please bear with me. Want I want to do is create a database on my local machine and also access/manipulate it from their. I thought MYSQL WB was the all in one tool to do this i.e it will also allow me to create a database and also make a MYSQL server from which to access it. But I came to know the Workbench is just a front end and you need to have a some kind of a seperate MYSQL server module for it to access.
The problem is I can't seem to find any link for a simple a server module on the MYSQL download site.
http://dev.mysql.com/downloads/ .
It has one Cluster Server but I don't think this is what I am looking for. If anyone could provide a link to the MYSQL server module using which I could connect MYSQL Workbench on my local host, and the steps to connect them that would be great.
The one your looking for is named MySQL Community Edition. The current version is 5.6.14. Just select your platform (mac, linux or windows) and follow the installation guide.
If you wish to have php/mysql then you can download xampp. It includes all the necessary tools. Or if you wish to install it separately then follow this for Windows,

MySQL Server start permission denied

I am a a newbie to database programming and I want to try out MySQL.
I just installed MySQL from the official website, I am running mac 10.8.2.
Anyways, whenever I try to run a simple command like $>mysql.server start
it says Permission denied.
I am able to open it through sudo but I would love to get this fixed as this is annoying me, that it wont work properly. I have been searching for the last two hours without finding a fix, so I was hoping anyone could give me a helping hand.
The easiest way is to install the MySQL Startup Item. Then you get a Preference pane for MySQL.
See http://dev.mysql.com/doc/refman/5.5/en/macosx-installation-startupitem.html for full instructions.
Re your comment:
It's often required for services like mysql.server need to run as a uid other than your user login. For instance, the MySQL data directory may only be writeable by the mysql uid. So starting such a service must be done from a user that can change the uid of the process. The root uid can do that, so it's necessary to use sudo to launch service processes like mysql.server.
TL;DR: YOU HAVE TO USE SUDO.
If you a absolute newbie to MYSQL and you just want to use the MYSQL server to test your code on you local MAC I would advice you to take a look at XAMPP / MAMP. Xampp offers a complete out of the box install for everything you need for a development servers (Apache server, MySQL, PHP, etc). Note, that I XAMPP / MAMP is not suitable for production server setting.
I personally use the XAMPP Windows version. I haven't tried MAMP but I have come across it many times . The XAMPP for Mac version seem not to have been update for a while so I suggest you give MAMP a try.
You could of course try to get your current install to work but that might require some work. Also with regard to firewall / security issues. With the out of the box version you will have to do a lot less. Why reinvent the wheel if you can easily install a out of the box version.

Thx for your help ;)
Try WAMP Server http://www.wampserver.com/en/ fastest easiest way to setup a MySQL database I have ever found.
I recommend you use USBWebserver. It comes with PhpMyAdmin that uses MySQL. Just search for it

MySQL install script

is there a way to automate to install MySQL without having to use the wizard to specify root password, etc. Basically, I need to install MySQL as simple as possible for the end user.
Thanks
I'm going to assume you mean windows. The Mysql MSI installer apparently has a quiet mode:
http://dev.mysql.com/doc/refman/5.1/en/windows-installer-msi-quiet.html
I would recommend Wampserver.
It is really easy to manage mysql server through wampserver interface and it comes with phpmyadmin.
