rhel7.2上升级MySQL5.6.18到5.7.11

本次使用二进制包采用out-place方式进行升级。

1、备份数据

    备份重于一切！

     各种备份方法mysqldump、cp.....

2、上传5.7.11软件包并解压

[root@rhel7 mysql]# ls
mysql5.6.18  mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz
[root@rhel7 mysql]# tar -zxvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz 
......
[root@rhel7 mysql]# mv mysql-5.7.11-linux-glibc2.5-x86_64 mysql5.7.11

[root@rhel7 mysql]# chown mysql:mysql -R mysql5.7.11
[root@rhel7 mysql]# ls -l
total 8
drwxr-xr-x. 13 mysql mysql 4096 Dec  5 15:17 mysql5.6.18
drwxr-xr-x.  9 mysql mysql 4096 Feb  2  2016 mysql5.7.11

3、停止旧版本数据库

#设置innodb_fast_shutdown=0
[root@rhel7 bin]# pwd
/opt/mysql/mysql5.6.18/bin
[root@rhel7 bin]# ./mysql -u root -p --execute="SET GLOBAL innodb_fast_shutdown=0"
Enter password: 
[root@rhel7 bin]# ./mysql -u root -p --execute="show global variables like 'innodb_fast_shutdown'"
Enter password: 
+----------------------+-------+
| Variable_name        | Value |
+----------------------+-------+
| innodb_fast_shutdown | 0     |
+----------------------+-------+
#关闭MySQL
[root@rhel7 bin]# ./mysqladmin -uroot -p shutdown 
Enter password: 
[root@rhel7 bin]# ps -ef |grep mysql
root      2771  1575  0 16:58 pts/0    00:00:00 grep --color=auto mysql

innodb_fast_shutdown参数解释参考：http://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_fast_shutdown

4、修改配置文件

#修改/etc/my.cnf文件
[root@rhel7 bin]# vi /etc/my.cnf
basedir = /opt/mysql/mysql5.7.11 #basedir指向新的软件目录

5、启动新版本软件

[root@rhel7 mysql5.7.11]# pwd
/opt/mysql/mysql5.7.11
[root@rhel7 mysql5.7.11]# ./bin/mysqld_safe --user=mysql &

[root@rhel7 mysql5.7.11]# ps -ef |grep mysql

7、重启MySQL以保证所有升级应用成功

[root@rhel7 mysql5.7.11]# ./bin/mysqladmin -uroot -p123456 shutdown
