+**删除多余的触发器**
 
- 
+```sql
+mysql> select trigger_schema,trigger_name from information_schema.triggers;
++----------------+----------------------------+
+| trigger_schema | trigger_name               |
++----------------+----------------------------+
+| sys            | sys_config_insert_set_user |
+| sys            | sys_config_update_set_user |
++----------------+----------------------------+
+2 rows in set (0.02 sec)
 
- 
+有两个没有删除掉的触发器，会导致后面的修改密码失败，
 
- 
+找到自己数据恢复的目录，查找以“.trg”为结尾的触发器文件，这里数据恢复目录为/var/mysql_bkdata/，执行find查找口令:
 
-**上面基本完成数据的恢复。考虑到恢复完成后，表mysql.user中不包含在RDS实例中创建的用户，需要新建。在新建用户前，执行如下命令**
+find /var/mysql_bkdata/ -iname *.trg
 
-**delete from mysql.db where user<>'root' and char_length(user)>0;**
+rm -rf /var/mysql_bkdata/mysql/user.TRG
+rm -rf /var/mysql_bkdata/mysql/proxies_priv.TRG
+```
 
-**delete from mysql.tables_priv where user<>'root' and char_length(user)>0;**
+#### 授权与创建用户
+
+ ```sql
+ 退出Mysql，重新登录进来，切换到mysql.user表，重新更新密码
+ 
+ update mysql.user set authentication_string=PASSWORD("DsideaL147258369") where user='root' and host='localhost';
+ 
+ flush privileges;
+ 
+ GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY 'DsideaL147258369' WITH GRANT OPTION;
