最近发现cron无效了
于是输入service crond status发现提示active，代码已经启动
>[root@iZbp1fna7ky0qz2jbj7gfpZ wwwlogs]# service crond status
Redirecting to /bin/systemctl status crond.service
● crond.service - Command Scheduler

不应该呢？脚本都没有成功执行
于是等了一会

看来是文件权限设置的不对，于是百度找到解决办法
>chmod 0600 /var/spool/cron/root
service crond restart
成功解决
