bitsCN.com 问题
执行 show engine innodb status/G 时,显示的信息不全,DEADLOCK相关信息太多,后面的都没了
原因:
这是mysql客户端的一个bug:BUG#19825,交互式客户端限制了输出信息最大为 64KB,因此更多的信息无法显示。

解决办法
解决方法有两种:
1. 启用 innodb_status_file
修改 my.cnf,增加类似下面一行
innodb_status_file = 1
就可以了。

2. 启用 innodb_monitor
mysqld在线运行时,创建 innodb_monitor 表,即可记录相关信息到日志文件
mysql> create table innodb_monitor ( id int ) engine = innodb;
相关的信息就会输出到 .err 日志文件里了。bitsCN.com
