修改core dump文件路徑：
方法1：臨時修改：
修改/proc/sys/kernel/core_pattern文件/proc目錄本身動態加載每次系統重啟都會重新加載因此種方法只能作臨時修改
/proc/sys/kernel/core_pattern
例：echo ‘/var/log/%e.core.%p’ > /proc/sys/kernel/core_pattern
/proc/sys/kernel/core_pattern
例：echo ‘/var/log/%e.core.%p’ > /proc/sys/kernel/core_pattern
方法2：永久修改：
使用sysctl -w name=value命令
例：/sbin/sysctl -w kernel.core_pattern=/var/log/%e.core.%p了更詳盡記錄core dump當時系統狀態通過下參數來豐富core文件命名：
%p - insert pid into filename 添加pid
%u - insert current uid into filename 添加當前uid
%g - insert current gid into filename 添加當前gid
%s - insert signal that caused the coredump into the filename 添加導致產生core的信號
%t - insert UNIX time that the coredump occurred into filename 添加core文件生成時的unix時間
%h - insert hostname where the coredump happened into filename 添加主機名
%e - insert coredumping executable name into filename 添加命令名
%u - insert current uid into filename 添加當前uid
%g - insert current gid into filename 添加當前gid
%s - insert signal that caused the coredump into the filename 添加導致產生core的信號
%t - insert UNIX time that the coredump occurred into filename 添加core文件生成時的unix時間
%h - insert hostname where the coredump happened into filename 添加主機名
%e - insert coredumping executable name into filename 添加命令名
