《Mysql学习mysql server is running with the --skip-grant-tables option》要点：
本文介绍了Mysql学习mysql server is running with the --skip-grant-tables option，希望对您有用。如果有疑问，可以联系我们。
MYSQL学习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
MYSQL学习第一种方法：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
MYSQL学习修改mysql的配置文件,把skip-grant-tables去掉后,重启mysql
MYSQL学习第二种：
MYSQL学习The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
MYSQL学习解决办法：
MYSQL学习mysql> set global read_only=0;
(关掉新主库的只读属性)
MYSQL学习flush privileges;
MYSQL学习set global read_only=1;(读写属性)
MYSQL学习flush privileges;
MYSQL学习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学习mysql> SET SESSION binlog_format = 'ROW';
mysql> SET GLOBAL binlog_format = 'ROW';
MYSQL学习解释：
MYSQL学习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学习
mysql> set global read_only=0;
Query OK, 0 rows affected (0.00 sec)
mysql> show variables like '%read_only%';
+------------------+-------+
| Variable_name | Value |

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%';
