MySql8.0.19最新版本創建用戶分配權限演示，You have an error in your SQL syntax權限分配問題解決方法

問題一：You have an error in your SQL syntax —語法問題

MySql8.0.19 版本分配權限這有了一些改變，不需要後面的identified by '123456a'了

mysql> grant all privileges on sonar_scan.* to 'sonar'@'%' identified by '123456
a';
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near 'ident
ified by '123456a'' at line 1

分配權限

mysql> grant all privileges on sonar_scan.* to 'sonar'@'%';
Query OK, 0 rows affected (0.24 sec)

問題二：You are not allowed to create a user with GRANT —權限問題

分配權限，% 代表全域，如果要遠程使用數據庫的話必須分配這個權限。

mysql> grant all privileges on sonar_scan.* to 'sonar'@'%';
Query OK, 0 rows affected (0.24 sec)

如果分配了全域，這個時候再分配本地就會報錯，其實 % 已經包含 localhost 了。

mysql> grant all privileges on sonar_scan.* to 'sonar'@'localhost';
ERROR 1410 (42000): You are not allowed to create a user with GRANT

如果硬要是分配本地的話，要執這麼一句就好了。要換回全域，在把 host 改成 % 就好了。

mysql>  update user set host='localhost' where user='sonar';
Query OK, 1 row affected (0.53 sec)
Rows matched: 1  Changed: 1  Warnings: 0

問題三：No database selected —沒選擇數據庫

用一句 use mysql 就能解決問題了。

mysql> update user set host='localhost' where user='sonar';
ERROR 1046 (3D000): No database selected
mysql> use mysql;
Database changed

mysql>  update user set host='localhost' where user='sonar';
Query OK, 1 row affected (0.53 sec)
Rows matched: 1  Changed: 1  Warnings: 0

創建數據庫分配權限演示

創建數據庫

mysql> create database sonar_scan default character set utf8 collate utf8_genera
l_ci;
Query OK, 1 row affected, 2 warnings (0.19 sec)

創建用戶

mysql> create user 'sonar' identified by '123456a';
Query OK, 0 rows affected (0.11 sec)

分配權限

mysql> grant all privileges on sonar_scan.* to 'sonar'@'%';
Query OK, 0 rows affected (0.24 sec)
