mysqlserverisrunningwiththe--skip-grant-tablesoption

The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
意思貌似MYSQL还运行在 --skip-grant-tables模式，如何让他回到原来的模式

第一种方法：原来在mysql.ini文件中配置了skip-grant-tables，前面加个#注释掉就可以了

修改mysql的配置文件，把skip-grant-tables去掉后，重启mysql

第二种：

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

解决办法：

mysql> set global read_only=0;
（关掉新主库的只读属性）

flush privileges;

set global read_only=1;(读写属性)

flush privileges;

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

解释：

set global read_only=0; 关闭只读,可以读写
set global read_only=1; 开始只读模式

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) 

set global read_only=0; 关闭只读,可以读写 set global read_only=1; 开始只读模式
