1.节点servera:主要是关防火墙（可以配置放行，但比较麻烦，不是本次实验的关注点，因而采取简单处理），关selinux，下载密钥（改为指定文件名，注意这里的大O，如果写成小o，会生成一个指定名称的空文件），创建secure-access文件（IO加密的开关文件），重启服务glusterd（注意可能存在进程关闭滞后的情况，手动pkill或kill -9，重启后一定要确认）。

6.节点workstation:主要是关防火墙（可以配置放行，但比较麻烦，不是本次实验的关注点，因而采取简单处理），关selinux，下载密钥（改为指定文件名，注意这里的大O，如果写成小o，会生成一个指定名称的空文件），创建secure-access文件（IO加密的开关文件,需要先创建上级目录）。
[root@workstation ~]# systemctl stop firewalld
[root@workstation ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
