linux下調試程序崩潰一般都有coredump生成，可以設置coredump生成路徑
#!/bin/sh
sed -i '/# End of file/i\* soft core unlimited' /etc/security/limits.conf
sed -i '/# End of file/i\* hard core unlimited' /etc/security/limits.conf
sed -i '/# End of file/i\* soft nofile 65535' /etc/security/limits.conf
sed -i '/# End of file/i\* hard nofile 65535' /etc/security/limits.conf
echo "kernel.core_pattern=/home/coredump/%e.core.%p.%t" >> /etc/sysctl.conf
echo "fs.suid_dumpable = 1" >> /etc/sysctl.conf
rm -rf /home/coredump
mkdir /home/coredump
echo "DAEMON_COREFILE_LIMIT='unlimited’" >> /etc/sysconfig/init
echo "coredump文件存放在/home/coredump路徑下"
sleep 7
reboot
