mysql 设置 innodb_print_all_deadlocks=ON, 保存死锁日志

Introduced	5.6.2
Command-Line Format	--innodb-print-all-deadlocks=#
System Variable	Name	innodb_print_all_deadlocks
	Scope	Global
	Dynamic	Yes
Permitted Values	Type	boolean
	Default	OFF

When this option is enabled, information about all deadlocks in InnoDB user transactions is recorded in the mysqld error log. Otherwise, you see information about only the last deadlock, using the SHOW ENGINE INNODB STATUS command. 

 

打开配置时，死锁日志存放到error_log配置的文件里面
