在三台主机上分别安装n2n并进行配置

host1:supernode/edge(192.168.172.1)
host2:edge(192.168.172.2)
host3:edge(192.168.172.3)
Community:linuxcache
Pre-Shared Key:5tgb6yhn7ujm

禁用防火墙

[root@host1 ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
[root@host1 ~]# systemctl stop firewalld
[root@host1 ~]#

安装工具

[root@host1 ~]# yum -y install git gcc automake

下载源代码
