错误:mysqldump: Couldn't execute 'SHOW FUNCTION STATUS WHERE Db = 'born_CRM'': Cannot load from mysql.proc. The table is probably corrupted (1728)
Warning: Using a password on the command line interface can be insecure.
mysqldump: Couldn't execute 'SHOW FUNCTION STATUS WHERE Db = 'mysql'': Cannot load from mysql.proc. The table is probably corrupted (1728)





开发在测试机上自己yum安装了一个mysql,目前centos的yum中的mysql版本是5.1,线上都5.6.20了....所以.擦屁股呗....升级测试机.

安装5.6.20 过程就忽略了..
mysqldump 导出数据:
mysql -e "show databases;" -uroot -p| grep -Ev "Database|information_schema|mysql|test|performance_schema" | xargs mysqldump -uroot -p --databases > mysql51.sql

在导入数据.
ps:mysql这个库我是单独导的,一开始我想的是,版本不一样,可能存在差异,所以,就单独导,以防失败.

整个过程都很顺利,后来做备份脚本的时候,发生问题了.....
[root@localhost dbbackup]# ./backup.sh
Warning: Using a password on the command line interface can be insecure.

mysqldump: Couldn't execute 'SHOW FUNCTION STATUS WHERE Db = 'born_CRM'': Cannot load from mysql.proc. The table is probably corrupted (1728)
Warning: Using a password on the command line interface can be insecure.
mysqldump: Couldn't execute 'SHOW FUNCTION STATUS WHERE Db = 'mysql'': Cannot load from mysql.proc. The table is probably corrupted (1728)



辗转反侧才发现问题所在,虽然mysqldump导出的是sql文件,但是mysql库中的表结构,视图等信息,仍然还是5.1的结构.所以需要执行升级脚本.
进入mysql 5.6安装目录:
[root@localhost ~]# cd /opt/mysql3307/bin/
[root@localhost bin]# mysql_upgrade
Looking for 'mysql' as: mysql
Looking for 'mysqlcheck' as: mysqlcheck
FATAL ERROR: Upgrade failed
[root@localhost bin]# mysql_upgrade  -uroot -p
