從MySQL 5.6至5.6 Percona的移動

Original post: http://anothermysqldba.blogspot.com/2013/10/moving-from-mysql-56-to-percona-56.html

Percona的5.6最近被釋放 （今天早些時候這篇文章的時候）。 因此，作為簡單的例子，什麼都沒有採取這種“更換下降嗎？”

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

雖然這將是很好的能夠移動從MySQL到Percona的這樣一個簡單的命令，你會得到衝突，如果你試過。

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

因此，你必須做到以下幾點。

你應該已經有備份，但以防萬一，創造一個又一個。

一個非常簡單的例子下面Xtrabackup

innobackupex ./

• 關閉MySQL的
• 刪除軟件包
• 安裝Percona的
• 啟動和連接。

# /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'"
See http://code.google.com/p/maatkit/source/browse/trunk/udf for more details
