Update MySQL version from 5.1 to 5.5 in CentOS 6.2

Question

I tried to update MySQL from 5.1 to 5.5 in CentOS 6.2. The following is the process I did:

1. rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm
2. yu         


        

Answer 1

You appear to have been using the wrong Webtatic Yum repository version than the one for your version of CentOS. See http://www.webtatic.com/projects/yum-repository/ for details

e.g.

rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm

You can use a yum plugin made by the IUS community to switch mysql-libs with mysql55w-libs. (the following assuming you still use Webtatic)

yum install mysql yum-plugin-replace
yum replace mysql --replace-with mysql55w

That should allow you to replace mysql with mysql55w-libs, whilst maintaining the older libmysqlclient for any dependencies.

If you see other packages than mysql being removed, then be careful, as they might be needed, but using this method, I've found to be reliable whenever I've used it.

I'm posting this solution as Remi's repository is not always the ideal solution. This method is more complex, but would never cause you to accidentally update your entire web stack by using repositories that use package names matching base distribution packages.

2015/08/19 - For those of you working on older (but still decent) hardware with a matching OS (typically 32 bit machines).

-- This will upgrade to mysql 5.6 community not 5.5 --

This worked for me after some research and mixing/matching/testing the answers found on various page of the internet (mainly from this page and http://dev.mysql.com/doc/refman/5.6/en/linux-installation-yum-repo.html). My OS shipped with mysql 5.1, I wanted to have 5.6.

My system

[root@host]# cat /etc/*release 
CentOS release 6.7 (Final)
[root@host]# uname -a
Linux host 2.6.32-573.3.1.el6.i686 #1 SMP Thu Aug 13 19:58:36 UTC 2015 i686 i686 i386 GNU/Linux
[root@host]# arch
i686

This is installed on a 2006 mac pro 1.1 (CPUs upgraded to 3.0GHz Intel Xeon X5365 Quad-Core).

Commands I ran

This was done almost immediately after a fresh install of the OS and system update via yum

list mysql currently installed

yum list installed | grep -i mysql

remove installed msql

yum remove mysql mysql-*

list mysql currently installed

yum list installed | grep -i mysql

Download rpm containing mysql 5.6

wget http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm

Install mysql

rpm -Uvh mysql-community-release-el6-5.noarch.rpm
yum install mysql mysql-server

list mysql currently installed

yum list installed | grep -i mysql

ensure mysql starts on reboot

chkconfig --list mysqld
sudo chkconfig mysqld on
chkconfig --list mysqld

Start mysql

service mysqld start
service mysqld status

Result

[root@host]# yum list installed | grep -i mysql
compat-mysql51.i686     5.1.54-1.el6.remi @remi

[root@host]# mysql --version
mysql  Ver 14.14 Distrib 5.6.26, for Linux (i686) using  EditLine wrapper

mysql config (I did not touch this yet but the info seems legit)

Some interesting basic but efficient performance tuning for mysql:

Good luck!

Edit

I had some issues creating users and granting permissions, this how it was fixed.

Error

ERROR 1054 (42S22) at line 1: Unknown column 'plugin' in 'mysql.user'

Fix

1. Logged on the server as root
2. Connected to mysql with a simple mysql
3. Checked the outcome of this statement: SELECT COUNT(1) column_count FROM information_schema.columns WHERE table_schema='mysql' AND table_name='user'; The result was 39, 43 is expected for mysql 5.6
4. Issued this statement to update the root password: update mysql.user set Password=PASSWORD('root') where User='root';
5. (Logged off mysql with exit)
6. Restarted mysql with: service mysqld restart
7. Ran: mysql_upgrade -uroot -proot --force
8. Reconnected to mysql with mysql -uroot -proot
9. Checked the outcome of this statement: SELECT COUNT(1) column_count FROM information_schema.columns WHERE table_schema='mysql' AND table_name='user'; The result was 43 as expected for mysql 5.6. I was then able to create my users and grant permissions as needed.

Answer 3

To list Old MySql

yum list installed | grep -i mysql

To remove Old MySql

yum remove mysql mysql-*

Remi Dependency on CentOS 6 and Red Hat (RHEL) 6

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

Install MySQL server

yum --enablerepo=remi,remi-test install mysql mysql-server

To list New MySql

yum list installed | grep -i mysql

start MySql server

/etc/init.d/mysqld start ## use restart after update

OR

service mysqld start ## use restart after update

chkconfig --levels 235 mysqld on

Last

mysql_upgrade -u root -p

Now my MySql version is 5.5.32

Hope it help some one

NOTE: Adding comments from @pim (in comments)

Just wanted to add that after the upgrade, my crontab was removed as well. Had to reinstall with "yum install vixie-cron" (CentOS 6) 

Answer 4

This blog post helped me upgrade from MySQL 5.5.15 to 5.5.28. That upgrade also had the problem with mysql-libs clashing with mysql55-libs.

Answer 5

I used the following commands to add a new YUM repo and make the update:

Download the Remi repo

cd /etc/yum.repos.d
wget http://rpms.famillecollet.com/enterprise/remi.repo

Install/Update the mysql version

yum --enablerepo=remi install mysql-server

OR

yum --enablerepo=remi update mysql-server

Answer 6

Use CentOS-Release-SCL is better and easy.

The Software Collections ( SCL ) Repository

# yum install centos-release-SCL
# yum install mysql55-mysql-server

Done.
