Linux下产生coredump并压缩保存

设置coredump大小为‘无限’
ulimit -c unlimited

开启coredump记录进程号
echo "1" > /proc/sys/kernel/core_uses_pid

指定coredump路径
echo "/home/panchen/core-%e-%p-%t"> /proc/sys/kernel/core_pattern

压缩coredump
cat /usr/local/sbin/core_helper

#! bin/sh
exec gzip - > /home/panchen/$1-$2-$3-$4.core.gz

echo "|/usr/local/sbin/core_helper" > /proc/sys/kernel/core_pattern
