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
旧的版本：Server version: 5.5.46-log MySQL Community Server (GPL)

3.解压文件
tar zxvf Percona-Server-5.6.27-rel75.0-Linux.x86_64.ssl101.tar.gz
4.创建目录
mkdir /app
mkdir /data/mysql3306
mv Percona-Server-5.6.27-rel75.0-Linux.x86_64.ssl101 /app/mysql5.6
chown -R mysql:mysql /app/mysql5.6
chown mysql:mysql /data/mysql3306
5.初始化新版本
/app/mysql5.6/scripts/mysql_install_db --user=mysql --basedir=/app/mysql5.6 --datadir=/data/mysql3306 --defaults-file=/app/mysql5.6/my.cnf
6.修改配置
[client]

[root@DB-master ~]# cp /app/mysql5.6/support-files/mysql.server /etc/init.d/mysqld3307
[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]#/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
