How to Install MySQL Database Using Yum groupinstall on CentOS

by Ramesh Natarajan on April 28, 2010

In this article, let us review how to install MySQL on CentOS using yum. Instead of searching and installing mysql and related packages one-by-one, it is better to install MySQL using yum groups.

If you are interested in installing the full LAMP stack, refer to our earlier article on how to install/upgrade LAMP using yum.

1. Identify the Group name of MySQL Packages

yum grouplist displays all package groups that are available in the repository. As shown below, mysql package group is called “MySQL Database”.

# yum grouplist | grep -i mysql
   MySQL Database

2. What is bundled in the “MySQL Database” group?

yum groupinfo displays all the packages that are bundled in a group. This displays the mandatory, default and optional packages that are available in that particular group.

As shown below, “MySQL Database” group contains 1 mandatory package, 6 default packages, and 5 optional packages.

# yum groupinfo "MySQL Database"
Group: MySQL Database
 Description: This package group contains packages useful for use with MySQL.
 Mandatory Packages:
 Default Packages:
 Optional Packages:

3. Install the “MySQL Database” group using yum groupinstall

yum groupinstall will install the “MySQL Database” group of packages as shown below.

# yum groupinstall "MySQL Database"

  libtool-ltdl.i386 0:1.5.22-7.el5_4 
  mx.i386 0:2.0.6-2.2.2 perl-DBI.i386 0:1.52-2.el5  


Note: If you are having some issues during the installation, verify the full mysql install log to see what you are missing.

4. Verify MySQL Installation

Execute rpm -qa, to confirm that the mysql related packages are installed.

# rpm -qa | grep -i mysql

Check the /etc/passwd and /etc/group to make sure it has created a mysql username and group.

# grep mysql /etc/passwd
mysql:x:27:27:MySQL Server:/var/lib/mysql:/bin/bash

# grep mysql /etc/group

5. MySQL Post installation – Execute mysql_install_db

mysql_install_db program will setup the necessary grant tables. The mysql_install_db program gets executed as part of the rpm installation. But, it doesn’t hurt to execute the mysql_install_db program again to make sure the grant tables are setup properly.

# /usr/bin/mysql_install_db --user=mysql
Installing MySQL system tables...OK
Filling help tables...OK
The latest information about MySQL is available on the web at

6. Start MySQL Server

# service mysqld status
mysqld is stopped

# service mysqld start
Starting MySQL:                                            [  OK  ]

7. Verify that the MySQL server is up and running.

# /usr/bin/mysqladmin version
/usr/bin/mysqladmin  Ver 8.41 Distrib 5.0.77, for redhat-linux-gnu on i686

| time_zone_transition      |
| time_zone_transition_type |
| user                      |

Stop and start the mysql server again to make sure they are no issues.

# service mysqld stop
Stopping MySQL:                                            [  OK  ]

# service mysqld start
Starting MySQL:                                            [  OK  ]

8. Change the MySQL root account password

Change the MySQL root account password to something secure.

# mysql -u root
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 5
Server version: 5.0.77 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> select host, user from mysql.user;
| host      | user |
| | root | 
| localhost |      | 
| localhost | root | 
5 rows in set (0.00 sec)

mysql> set password for 'root'@'localhost' = PASSWORD('DoNotTell$AnyBody');
Query OK, 0 rows affected (0.00 sec)

mysql> set password for 'root'@'' = PASSWORD('DoNotTell$AnyBody');
Query OK, 0 rows affected (0.00 sec)

Make sure you are able to login to MySQL using the new password as shown below.

# mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

# mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 7
Server version: 5.0.77 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

Thanks a lot for this. Nice easy to follow guide. Was up and running in minutes.

3 Bob September 14, 2010 at 2:33 pm

Exactly what I needed. Thanks!

One more thing that people may find useful – once you have MySQL running you can run “/usr/bin/mysql_secure_installation” to button up security a bit before going into production.

Great Tutorial up to the point where you set the point where you change the root password….
mysql> set password for ‘root’@'localhost’ = PASSWORD(‘DoNotTell$AnyBody’);
Query OK, 0 rows affected (0.00 sec)

mysql> set password for ‘root’@’′ = PASSWORD(‘DoNotTell$AnyBody’);
Query OK, 0 rows affected (0.00 sec)

What is the root password now?

When I type # mysql -u root -p
Enter password:
I have know idea what it was set to?

18 norm July 29, 2012 at 7:12 pm

Well Figured out the problem(‘DoNotTell$AnyBody’) just figured out this was a dummy variable. Emphasis on “dummy” . Changed password. Now all set.


19 Manzoorul Hassan December 28, 2012 at 4:38 pm

Excellent set of instructions. Now I just need to figure out how to update / upgrade to v5.5.9. The above instruction got v5.0.95 installed.
