解决方法如下：
1、查看数据状态
root@storm-master-01:/root#ps -ef|grep mysql
root 68391 67024 0 16:01 pts/4 00:00:00 mysql -h192.168.22.22 -uloan -px xxxx -P3308
mysql 72949 68459 16 17:55 pts/6 00:00:00 /usr/local/mysql/bin/mysqld --defaults-file=/data/backup/backup-my.cnf
root 72980 68459 0 17:55 pts/6 00:00:00 grep --color=auto mysql
2、登录数据库如下
root@storm-master-01:/data/backup#mysql_upgrade -h192.168.22.22 -u root -p --force -P3308 sock=/data/backup/mysql3308.sock
