MySQL Study之--Percona server 5.5升级5.6
MySQL Study之--Percona server 5.5升级5.6系统环境：
操作系统：CentOS_6.5(64)
MySQL: Percona server 5.5(5.6)
一、升级的目的
为什么MySQL升级是必须的? 原因有很多,比如：为了使用新增的特性,基于性能方面的考量, 修复的bug. 但是在没有充分的测试以前就应用到你的应用中是非常危险的, 因为升级可以能会让你的应用不能正常运作- 也可能引起性能的问题. 此外, 我建议你关注MySQL的发布信息和Percona Server - 看看最近的版本有什么变化. 也许在在最新的版本中已修复了某个你正在烦恼的问题.
二、升级的方式
通常情况下，有两中升级方式：
[*] 直接升级:安装好新版本数据库后，利用已经存在的数据文件夹，同时运行mysql_upgrade脚本来升级。
[*] SQL 导出： 从一个较老版本的mysql把数据导出，然后恢复到新版本的数据库中。(利用mysqldump工具)。
相比之下，第二种方式更安全些，但是这也会使得升级的过程要慢一些。
理论上讲，最安全的方式是：
[*] 导出所有用户的权限
[*] 导出所有数据并恢复到新版本数据库中
[*] 恢复用户权限到新数据库中
三、升级的步骤
1、安装percona server 5.5
# uname -a

Percona-Server-devel-55-5.5.46-rel37.5.el6.x86_64.rpm

Percona-Server-test-55-5.5.46-rel37.5.el6.x86_64.rpm
安装percona server与系统自带的mysql冲突，首先卸载系统自带mysql：
[root@cent65 percona-55]# rpm -ivh *
warning: Percona-Server-55-debuginfo-5.5.46-rel37.5.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key> error: Failed dependencies:
MySQL conflicts with mysql-5.1.71-1.el6.x86_64
MySQL-server conflicts with mysql-server-5.1.71-1.el6.x86_64
卸载mysql：
# rpm -e mysql-server --nodeps
# rpm -e mysql --nodeps
# rpm -e mysql-devel --nodeps
安装percona server：
# rpm -ivh *
warning: Percona-Server-55-debuginfo-5.5.46-rel37.5.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h cent65 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default.This is
strongly recommended for production servers.
See the manual for more instructions.
Please report any problems at
https://bugs.launchpad.net/percona-server/+filebug
Percona recommends that all production deployments be protected with a support
contract (http://www.percona.com/mysql-suppport/) to ensure the highest uptime,
be eligible for hot fixes, and boost your team's productivity.
Percona Server is distributed with several useful UDF (User Defined Function) from Percona Toolkit.
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://www.percona.com/doc/percona-server/5.5/management/udf_percona_toolkit.html for more details

2、启动mysql server
# service mysql start
Starting MySQL (Percona Server)....
# netstat -an |grep :3306
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN
修改用户口令：
# mysqladmin -u root password "oracle"
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'
连接mysql server：
# mysql -u root -p
Enter password:

二、准备升级percona server5.5到5.6
安装percona toolkit工具：
首先通过yum（本地库）安装perl软件：
# yum install -y perl-IO-Socket-SSL* --enablerepo=c6-media
# yum install -y perl-TermReadKey*--enablerepo=c6-media
# rpm -ivh percona-toolkit-2.2.10-1.noarch.rpm
warning: percona-toolkit-2.2.10-1.noarch.rpm: Header V4 DSA/SHA1 Signature, key> Preparing... ###########################################
1:percona-toolkit ###########################################
1) 获取用户和权限信息. 该操作会备份所有用户的权限
# pt-show-grants --user=root --ask-pass --flush >/home/mysql/grants.sql
Enter password:
查看sql scripts：
# cat grants.sql
- Grants dumped by pt-show-grants
-- Dumped from server Localhost via UNIX socket, MySQL 5.5.46-37.5 at 2015-12-03 12:22:00

GRANT PROXY ON ''@'' TO 'root'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;
2)、dump 5.5数据库实例的所有信息(除去mysql, information_schema 和performance_schema数据库)
# mysql -uroot -p -BNe "SELECT SCHEMA_NAME FROM INFORMATION_SCHEMA.SCHEMATA WHERE SCHEMA_NAME NOT IN ('mysql', 'performance_schema', 'information_schema')" | tr 'n' ' ' > /home/mysql/dbs-to-dump.sql
Enter password:
查看sql scripts：
# cat dbs-to-dump.sql
prod
test
# mysqldump -u root -p --routines --events --single-transaction --databases $(cat /home/mysql/dbs-to-dump.sql) > /home/mysql/full-data-dump.sql
Enter password:
# cat full-data-dump.sql
-- MySQL dump 10.13Distrib 5.5.46-37.5, for Linux (x86_64)

3)、停止数据库
# service mysql stop
Shutting down MySQL (Percona Server).......
# mv /var/lib/mysql /var/lib/mysql55
4)、 移动旧数据库(5.5版本)的数据目录(假设是/var/lib/mysql,此处应该改为你自己的数据目录)
#mv /var/lib/mysql /var/lib/mysql55
#mkdir /var/lib/mysql
#chown -R mysql:mysql /var/lib/mysql
三、安装Percona Server 5.6
# ls -l

Percona server 5.5会与5.6的软件有冲突，所以5.6的安装需要强制安装：

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h cent65 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test

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://www.percona.com/doc/percona-server/5.6/management/udf_percona_toolkit.html for more details
------------至此，Percona Server 5.6安装成功 ！
四、将数据import到server 5.6
1、启动mysql server
# service mysql start
Starting MySQL (Percona Server).
# netstat -an|grep :3306
tcp 0 0 :::3306 :::* LISTEN
2、导入用户权限表
# mysql -u root -p Copyright (c) 2009-2015 Percona LLC and/or its affiliates

1 row in set (0.00 sec)
查看表信息：
mysql> select * from emp;
+------+-------+
|> +------+-------+
| 10 | tom |
| 20 | jerry |
| 30 | rose|
+------+-------+
3 rows in set (0.00 sec)
---------数据库可以正常访问，至此升级结束！
此时, 所有的表都在MySQL 5.6中重建及重新加载完成,所以所有的二进制文件对MySQL 5.6可用. 同时也你完成了最干净/最稳定的升级过程,你可以恢复你的应用- 这个升级过程和valina MySQL与Percona Server的升级过程是一样的.甚至你可以把Oracle MySQL升级到Percona Server. 比如: 把Oracle MySQL 5.5升级到Percona Server 5.6. 再次强调: MySQL的升级过程和Percona Server的升级过程是一样的,只需要将Percona Server 替换成Oracle MySQL即可.
