《Mysql學習mysql server is running with the --skip-grant-tables option》要點：
本文介紹了Mysql學習mysql server is running with the --skip-grant-tables option，希望對您有用。如果有疑問，可以聯(lián)系我們。

MYSQL學習The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
意思貌似MYSQL還運行在 --skip-grant-tables模式,如何讓他回到原來的模式

MYSQL學習第一種方法：原來在mysql.ini文件中配置了skip-grant-tables,前面加個#注釋掉就可以了

MYSQL學習修改mysql的配置文件,把skip-grant-tables去掉后,重啟mysql

MYSQL學習第二種：

MYSQL學習The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

MYSQL學習解決辦法：

MYSQL學習mysql> set global read_only=0;
(關掉新主庫的只讀屬性)

MYSQL學習flush privileges;

MYSQL學習set global read_only=1;(讀寫屬性)

MYSQL學習flush privileges;

MYSQL學習Cannot execute statement: impossible to write to binary log since BINLOG_FORMAT = STATEMENT and at least one table uses a storage engine limited to row-based logging. InnoDB is limited to row-logging when transaction isolation level is READ COMMITTED or READ UNCOMMITTED.

MYSQL學習mysql> SET SESSION binlog_format = 'ROW';
mysql> SET GLOBAL binlog_format = 'ROW';

MYSQL學習解釋：

MYSQL學習set global read_only=0; 關閉只讀,可以讀寫
set global read_only=1; 開始只讀模式

MYSQL學習
mysql> set global read_only=0; 
Query OK, 0 rows affected (0.00 sec) 
 
mysql> show variables like '%read_only%'; 
+------------------+-------+ 
| Variable_name  | Value | 
+------------------+-------+ 
| innodb_read_only | OFF  | 
| read_only    | OFF  | 
| tx_read_only   | OFF  | 
+------------------+-------+ 
3 rows in set (0.00 sec) 
 
mysql> set global read_only=1; 
Query OK, 0 rows affected (0.00 sec) 
 
mysql> show variables like '%read_only%'; 
+------------------+-------+ 
| Variable_name  | Value | 
+------------------+-------+ 
| innodb_read_only | OFF  | 
| read_only    | ON  | 
| tx_read_only   | OFF  | 
+------------------+-------+ 
3 rows in set (0.00 sec) 

MYSQL學習set global read_only=0; 關閉只讀,可以讀寫 set global read_only=1; 開始只讀模式
