通过在管理节点执行然后下发各个节点ssh被拒绝,防火墙都已经关闭状态,网络也是互通的

告警信息

设备无告警问题

处理过程

1、修改各个节点的/etc/hosts文件,把所有节点的ip和设置的主机名写入该节点文件,必须保证与规划工具里面设置的一样并且一一对应 

      格式:    服务器IP    服务器主机名 

2、修改各个节点的/etc/ssh/ssh_conf, GSSAPIAuthentication yes --->GSSAPIAuthentication no(选做)

3、vi /etc/sysconfig/selinux 

 selinux=disabled


根因

根据自己设定的主机名和IP信息与规划表的一样不能错,并且在/etc/hosts中注册各个节点的IP和主机名信息都与规划表中的信息一致,并且把selinux关闭

解决方案

1、修改各个节点的/etc/hosts的文件

2、vi /etc/sysconfig/selinux 

    selinux=disabled

3、防火墙关闭
