lepus监控mysql5.7出现的问题：

登陆192.168.10.9机器和192.168.10.8机器查看mysql5.7的sql_mode默认的模式为：

mysql> SELECT @@GLOBAL.sql_mode;

+-------------------------------------------------------------------------------------------------------------------------------------------+

| @@GLOBAL.sql_mode                                                                                                                         |

+-------------------------------------------------------------------------------------------------------------------------------------------+

| ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |

+-------------------------------------------------------------------------------------------------------------------------------------------+

SET global sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'


这样mysql不需要重启


或者是写入my.cnf

[mysqld]

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION


重启mysql5.7解决
