MySQLの5.6からPercona 5.6への移行

Original post: http://anothermysqldba.blogspot.com/2013/10/moving-from-mysql-56-to-percona-56.html
Percona 5.6が最近リリースされた (以前の今日、この記事の時点で)。 だから、これに移行するために、すべてのことがかかりますか何を簡単な例として、 "交換の低下?"

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

それはこのような単純なコマンドでMySQLからPerconaに移動できるようにするとよいだろうが、あなたはそれを試してみました場合は、競合を取得します。

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

だからではなく、次のことを行う必要があります。

すでにバックアップを持っているが、念のために別のものを作成する必要があります。

と下の極めて単純な例Xtrabackup
innobackupex ./

  • MySQLの電源を切ります
  • パッケージを削除
  • Perconaをインストール
  • 起動して接続します。

# /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
