MySQL5.6.26升级到MySQL5.7.9实战方案

前言

某大公司升级方案,由于公司经常安全扫描,每个版本都有自身的BUG,为了安全到一定时间都会升级到新的版本。本案例采用单机环境升级方案,在单机中搭建主从方案。

1.单机环境

IP:172.16.0.111

系统:SUSE 11

MySQL旧版本:5.6.26

MySQL新版本:5.7.9

2.升级前准备

注意:升级之前查看磁盘空间充足,能在本机搭建从库。

新版本目录

软件目录:/app/mysql5.7/

数据目录:/data/mysqldata/

配置文件:/app/mysql5.7/my.cnf

3.1.解压文件

mysql01:~# tar zxvf mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz

3.2.移动解压文件

mysql01:~ # mvmysql-5.7.9-linux-glibc2.5-x86_64 /app/mysql5.7

mysql01:~ # chown -R mysql:app/app/mysql5.7

3.3.创建数据目录

mysql01:~ # mkdir /data/mysqldata

mysql01:~ # chown -R mysql:app/data/mysqldata

3.4.初始化数据

注意:初始化和之前版本不一样了,初始化时有初始化密码的

mysql01:/data/mysqldata# /app/mysql5.7/bin/mysqld--initialize --user=mysql --basedir=/app/mysql5.7--datadir=/data/mysqldata

2015-12-03T23:34:12.688857Z0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use--explicit_defaults_for_timestamp server option (see documentation for moredetails).

2015-12-03T23:34:12.927838Z0 [Warning] InnoDB: New log files created, LSN=45790

2015-12-03T23:34:12.968656Z0 [Warning] InnoDB: Creating foreign key constraint system tables.

2015-12-03T23:34:13.025810Z0 [Warning] No existing UUID has been found, so we assume that this is thefirst time that this server has been started. Generating a new UUID:5c20785f-9a16-11e5-a525-000c294cec8f.

2015-12-03T23:34:13.027457Z0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed'cannot be opened.

2015-12-03T23:34:13.028709Z1 [Note] A temporary password is generated for root@localhost: O-FxRJjl_1Yi #初始化密码

3.5.修改配置文件

mysql01:~ # cp /app/mysql5.6/my.cnf /app/mysql5.7/my.cnf

mysql01:/data/mysqldata # vi /app/mysql5.7/my.cnf

[client]

socket=/app/mysql5.7/mysql.sock

binlog-format=ROW

server_id=112

log-slave-updates=1

3.6修改启动脚本

mysql01:/data/mysqldata # cp/app/mysql5.7/support-files/mysql.server /etc/init.d/mysql3307

mysql01:/data/mysqldata # vi/etc/init.d/mysql3307

修改之处

basedir=/app/mysql5.7

datadir=/data/mysqldata

mysql01:/data/mysqldata # chmod +x/etc/init.d/mysql3307

启动新版本MYSQL

mysql01:/data/mysqldata # /etc/init.d/mysql3307 start

Starting MySQL..done

进入MYSQL

mysql01:/data/mysqldata #/app/mysql5.7/bin/mysql-uroot -pO-FxRJjl_1Yi -P3307 --socket=/app/mysql5.7/mysql.sock

4.导出与导入数据

导出数据

mysql@mysql01 ~ $mysqldump -uroot -p --default-character-set=utf8 --all-databases--single-transaction --routines --triggers --events --master-data=2 --socket=/app/mysql5.6/mysql.sock >mysql20151211.sql

注解:

--all-databases 导出所有数据库

--single-transaction

该选项在导出数据之前提交一个BEGINSQL语句,BEGIN不会阻塞任何应用程序且能保证导出时数据库的一致性状态。它只适用于多版本存储引擎,仅InnoDB。本选项和--lock-tables选项是互斥的,因为LOCKTABLES会使任何挂起的事务隐含提交。要想导出大表的话,应结合使用--quick选项。

--routines,-R

导出存储过程以及自定义函数。

--triggers

导出触发器。该选项默认启用,用--skip-triggers禁用它。

--events,-E

导出事件。

--master-data

该选项将binlog的位置和文件名追加到输出文件中。如果为1,将会输出CHANGEMASTER命令;如果为2,输出的CHANGEMASTER命令前添加注释信息。该选项将打开--lock-all-tables选项,除非--single-transaction也被指定(在这种情况下,全局读锁在开始导出时获得很短的时间;其他内容参考下面的--single-transaction选项)。该选项自动关闭--lock-tables选项。

mysql@mysql01 ~ $more mysql20151211.sql

#主从搭建时需要的

把备份数据导入新版本

mysql@mysql01 ~ $/app/mysql5.7/bin/mysql-uroot -pO-FxRJjl_1Yi -P3307 --socket=/app/mysql5.7/mysql.sock < mysql20151211.sql

查看导入成功

5.主从搭建

在Master上增加一个用于复制的账号:

root@(none) 07:52:47>GRANT REPLICATIONSLAVE ON *.* TO &#39;repl&#39;@&#39;172.16.0.%&#39; IDENTIFIED BY &#39;123456&#39;;

Query OK, 0 rows affected (1.01 sec)

在SLAVE上执行如下命令

mysql@mysql01 ~ $/app/mysql5.7/bin/mysql-uroot -pO-FxRJjl_1Yi -P3307 --socket=/app/mysql5.7/mysql.sock

6.执行mysql_upgrade命令

官方提到执行这命令可以让原数据启用到新版本的特性,注意:GTID复制不要开启

Checking if update is needed.

7.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

mysql01:/data/mysqldata #/etc/init.d/mysqld stop

Shutting down MySQL....done

停止从库

mysql01:/data/mysqldata #/etc/init.d/mysql3307 stop

Shutting down MySQL....done

修改启动

mysql01:/data/mysqldata # cd /etc/init.d/

mysql01:/etc/init.d # mv mysqld mysqlold

mysql01:/etc/init.d # mv mysql3307 mysqld

修改配置文件

mysql01:/etc/init.d # vi/app/mysql5.7/my.cnf

[client]

….

port=3306

[mysqld]

…………

port=3306

……

最后启动新版本

mysql01:/etc/init.d # /etc/init.d/mysqldstart

Starting MySQL. Done

清除同步

mysql> resetslave all;

Query OK, 0 rows affected (0.00 sec)

mysql> show slave status\G;

Empty set (0.00 sec)

ERROR:

No query specified

把环境变量修改如下

mysql@mysql01 ~ $vi .profile

export MYSQL_HOME=/app/mysql5.7

export MY_BASEDIR_VERSION=/app/mysql5.7

export PATH=/app/mysql5.7/bin:$PATH

export LD_LIBRARY_PATH=/app/mysql5.7/lib

export PS1=&#39;\u@\H \w \$&#39;

让环境变量生效

mysql@mysql01 ~ $source .profile

注:过几天如果应用一切正常。

最后清理旧版本的数据与软件
