# Restart nagios to forcibly update retention.dat

会重启nagios服务，看下manage_services.sh

有趣的是$BASEDIR/manage_services.sh restart nagios会重启nagios服务
systemctl status nagios能看到服务的位置
Process: 8416 ExecStartPre=/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
这个是有权限修改的
-rwxrwxrwx 1 nagios nagios 16864 Jan 17 05:09 /usr/local/nagios/bin/nagios
所以重新编译一个丢进去让她启动弹shell回来就行
