本次测试mysql 5.6.40升级至MySQL 5.7.19过程，采用本地升级的方法。
1、安装MySQL5.7.19，并关闭MySQL5.7.19的服务
[root@mysql5 mysql]# /usr/local/mysql5.7/bin/mysqladmin -h127.0.0.1 -uroot -p shutdown

2、关闭MySQL 5.6.40服务
[root@mysql5 mysql]# /usr/local/mysql5.6/bin/mysqladmin -h127.0.0.1 -uroot -p shutdown

3、复制MySQL 5.6.40的data目录至MySQL 5.7的data
[root@mysql5 mysql]# cp -rp /data/mysql5.6/data /data/mysql5.7/data

4、启动MySQL 5.7.19服务
[root@mysql5 mysql]# /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
[root@mysql5 mysql]# ps -elf | grep -v grep | grep mysql
root 26407 7822 0 10:18 pts/4 00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf
