尝试向用户授予权限后,MySQL服务停止
作者：互联网
我正在使用MySQL 5.6,我试图为特定数据库创建一个超级用户,但我得到了
ERROR 1396 (HY000): Operation CREATE USER failed for 'superuser'@'%'
然后我想也许已经有一个用户具有相同的名称和密码.我刷新了权限并运行以下查询：
grant all privileges on db1.* to 'superuser'@'localhost'
在那个查询之后我得到：ERROR 2013(HY000)：在查询期间丢失了与MySQL服务器的连接
和MySQL服务停止工作.
解决方法:
我认为你的问题归结为拨款错位.
运行此查询时
SELECT COUNT(1) column_count FROM information_schema.columns
WHERE table_schema='mysql' AND table_name='user';
您应该使用以下号码
>如果你得到43,MySQL 5.6
>如果你得到42,MySQL 5.5
>如果你得到39,MySQL 5.1
>如果你得到37,MySQL 5.0
它只是意味着您忘记了另一个升级步骤
# mysql_upgrade --upgrade-system-tables
这应该填写缺少的列.
我之前讨论过这个

既然你说mysql.user有39,那就意味着你从MySQL 5.1到MySQL 5.5时没有运行mysql_upgrade –upgrade-system-tables.
老实说,我不知道在MySQL 5.6中运行mysql_upgrade –upgrade-system-tables是否会成功重新调整mysql.user两个版本.
我建议通过以下方式制作副本
net stop mysql
cd D:\MySQL\mysql
copy user.frm user1.frm
copy user.MYD user1.MYD
copy user.MYI user1.MYI
net start mysql
完成复制后,继续运行mysql_upgrade –upgrade-system-tables.登录mysql并运行SELECT COUNT(1)column_count FROM information_schema.columns WHERE table_schema =’mysql’AND table_name =’user’;再次.希望它会读到43.
如果没有,请像这样复制用户文件
net stop mysql
cd D:\MySQL\mysql
del user.*
move user1.frm user.frm
move user1.MYD user.MYD
move user1.MYI user.MYI
net start mysql
如果要手动更改设计,请尝试以下操作：
使用MySQL 5.6布局创建mysql.user_new
CREATE TABLE mysql.user_new (
`Host` char(60) COLLATE utf8_bin NOT NULL DEFAULT '',
`User` char(16) COLLATE utf8_bin NOT NULL DEFAULT '',
`Password` char(41) CHARACTER SET latin1 COLLATE latin1_bin NOT NULL DEFAULT '',
`Select_priv` enum('N','Y') CHARACTER SET utf8 NOT NULL DEFAULT 'N',
`Insert_priv` enum('N','Y') CHARACTER SET utf8 NOT NULL DEFAULT 'N',

PRIMARY KEY (`Host`,`User`)

将拨款从旧移动到新
INSERT INTO mysql.user_new
(Host,User,Password,Select_priv,Insert_priv,Update_priv,Delete_priv,
Create_priv,Drop_priv,Reload_priv,Shutdown_priv,Process_priv,File_priv,
Grant_priv,References_priv,Index_priv,Alter_priv,Show_db_priv,Super_priv,
Create_tmp_table_priv,Lock_tables_priv,Execute_priv,Repl_slave_priv,
Repl_client_priv,Create_view_priv,Show_view_priv,Create_routine_priv,
Alter_routine_priv,Create_user_priv,Event_priv,Trigger_priv,ssl_type,
ssl_cipher,x509_issuer,x509_subject,max_questions,
max_updates,max_connections,max_user_connections)
SELECT
Host,User,Password,Select_priv,Insert_priv,Update_priv,Delete_priv,
Create_priv,Drop_priv,Reload_priv,Shutdown_priv,Process_priv,File_priv,
Grant_priv,References_priv,Index_priv,Alter_priv,Show_db_priv,Super_priv,
Create_tmp_table_priv,Lock_tables_priv,Execute_priv,Repl_slave_priv,
Repl_client_priv,Create_view_priv,Show_view_priv,Create_routine_priv,
Alter_routine_priv,Create_user_priv,Event_priv,Trigger_priv,ssl_type,
ssl_cipher,x509_issuer,x509_subject,max_questions,
max_updates,max_connections,max_user_connections
FROM mysql.user;
更新root的Create_tablespace_priv
UPDATE mysql.user_new SET Create_tablespace_priv='Y' WHERE user = 'root';
调节开关
ALTER TABLE mysql.user RENAME mysql.user_old;
ALTER TABLE mysql.user_new RENAME mysql.user;
FLUSH PRIVILEGES;
试一试,看看一切是否正常！
