Moving from MySQL 5.6 to Percona 5.6

Percona 5.6 was recently released (yesterday at the time of this post). So as simple example what all does it take to move to this "drop in replacement?"

Oct  7 06:47 Percona-Server-56-debuginfo-5.6.13-rel61.0.461.rhel6.x86_64.rpm
Oct  7 06:47 Percona-Server-client-56-5.6.13-rel61.0.461.rhel6.x86_64.rpm
Oct  7 06:47 Percona-Server-devel-56-5.6.13-rel61.0.461.rhel6.x86_64.rpm
Oct  7 06:47 Percona-Server-server-56-5.6.13-rel61.0.461.rhel6.x86_64.rpm
Oct  7 06:47 Percona-Server-shared-56-5.6.13-rel61.0.461.rhel6.x86_64.rpm

Oct  7 06:47 Percona-Server-test-56-5.6.13-rel61.0.461.rhel6.x86_64.rpm
# rpm -qa | grep MySQL
MySQL-server-5.6.13-1.el6.x86_64
MySQL-devel-5.6.13-1.el6.x86_64
MySQL-shared-compat-5.6.13-1.el6.x86_64
perl-DBD-MySQL-4.013-3.el6.x86_64
MySQL-python-1.2.3-0.3.c1.1.el6.x86_64
MySQL-client-5.6.13-1.el6.x86_64
MySQL-shared-5.6.13-1.el6.x86_64
MySQL-test-5.6.13-1.el6.x86_64

# rpm -Uhv *.rpm


While it would be nice to be able to Move from MySQL to Percona with such a simple command you will get conflicts if you tried it.

Percona-Server-server-56-5.6.13-rel61.0.461.rhel6.x86_64 conflicts with file from package MySQL-server-5.6.13-1.el6.x86_64


So instead you have to do the following.

You should already have backups but just in case create another one.

An extremely simple example below with Xtrabackup

innobackupex ./ 


• Turn off MySQL 
• Remove the packages 
• Install Percona 
• Start and connect.

# /etc/init.d/mysql stop
Shutting down MySQL..                                      [  OK  ]
# rpm -e MySQL-server MySQL-devel MySQL-client MySQL-shared MySQL-test mysql-workbench-community

# rpm -ihv Percona-Server-*.rpm

Percona Server is distributed with several useful UDF (User Defined Function) from Maatkit.
Run the following commands to create these functions:
mysql -e "CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME 'libfnv1a_udf.so'"
mysql -e "CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME 'libfnv_udf.so'"
mysql -e "CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME 'libmurmur_udf.so'"
