2016-04-26 23:53:47 18906 [ERROR] Incorrect definition of table mysql.proc: expected column 'comment' at position 15 to have type text, found type char(64).
2016-04-26 23:53:47 18906 [Note] /usr/local/mysql/bin/mysqld: Normal shutdown

可能原因是未删除 原来的/usr/local/mysql/var 数据库目录就进行了安装的原因，上传具体安装日志看看，也可以自己/usr/local/mysql/bin/mysql_upgrade -u root -p 看一下能否修复

不行，解决不了。

现在启动时提示
