mysql5.5.46升级到Percona Server 5.6.27

1.升级前的准备

查看本机openssl版本

root@DB-Slave mysql5.6]# rpm -qa | grep ssl

openssl-1.0.1e-42.el6_7.2.x86_64

openssl-devel-1.0.1e-42.el6_7.2.x86_64

https://www.percona.com/downloads/Percona-Server-5.6/LATEST/软件下载地址

 Percona-Server-5.6.27-rel75.0-Linux.x86_64.ssl101.tar.gz的openssl就是1.0.1版本的

2.安装新的版本

[root@DB-master ~]# vi  /etc/init.d/mysqld3307

….

…..

basedir=/app/mysql5.6

datadir=/data/mysql3306

…..

…

[root@DB-master ~]# chmod +x /etc/init.d/mysqld3307

启动新版本

[root@DB-master ~]# /etc/init.d/mysqld3307 start

Starting MySQL (Percona Server)... SUCCESS!

8.旧版本数据导出，导入新版本

导出

mysqldump -uroot -p123456 --socket=/var/lib/mysql/mysql.sock  --max_allowed_packet=1048576 --net_buffer_length=16384  --default-character-set=utf8 --all-databases --single-transaction --routines --triggers --events --master-data=2 >all2016114.sql

 

[root@DB-master ~]# more all2016114.sql

….

….

-- CHANGE MASTER TO MASTER_LOG_FILE='master-bin.000035', MASTER_LOG_POS=19461006;

注意：主从同步需要

…..

….

导入

mysql -uroot -p123456 --socket=/app/mysql5.6/mysql.sock < all2016114.sql

 

9.执行mysql_upgrade

注意一定要执行可以让旧的数据有新的版本功能

/app/mysql5.6/bin/mysql_upgrade -uroot -p123456 --socket=/app/mysql5.6/mysql.sock

 

10.主从搭建

旧版本

[root@DB-master mysql3306]# mysql -uroot -p123456

11.升级切换

把主库停止，把从库停止后，端口修改成3306，因为为了对生产库没有影响。在停止时必须和应用联系。

停止主库

[root@DB-master mysql3306]#/data/mysqldata #/etc/init.d/mysql stop

Shutting down MySQL....                                             done

停止从库

[root@DB-master ~]# /etc/init.d/mysqld3307 stop

Shutting down MySQL (Percona Server).... SUCCESS!

修改启动

[root@DB-master ~]#  cd /etc/init.d/

[root@DB-master ~]# mv mysql mysqlold

[root@DB-master ~]# mv mysql3307 mysql

 

 

修改配置文件

[root@DB-master ~]#/etc/init.d # vi/app/mysql5.6/my.cnf

 

[client]

….

port=3306

…

 [mysqld]

…………

port=3306

……

 

 

最后启动新版本

[root@DB-master ~]# /etc/init.d/mysql start

Starting MySQL (Percona Server)... SUCCESS!  

 

清除同步

Query OK, 0 rows affected (0.00 sec)

 

mysql> show slave status\G;

Empty set (0.00 sec)
