InnoDB: Cannot allocate memory for the buffer pool

Mysql今天又突然挂掉了，重启还是报昨天一样的错误
The server quit without updating PID file (/bak/local/mysql/var/file.pid).

错误日志如下：

昨天是将innodb_buffer_pool_size从512M加大到了1024M,看来并没有从根本上解决问题。
试着重启了多次还是不管用。

报出以下错误:

说无法分配内存缓冲池

然后用free命令查看了一下可用内存只有1百多M,果断将目前服务器上不用的tomcat给kill掉，然后重启成功。
并且将 my.cnf 中的innodb_buffer_pool_size修改为512M。

my.cnf以下配置是禁示innodb的参数，如果是开启只需要注释掉即可,目前默
