yum インストールランプ

systemctl stop firewalld.service #停止firewall 
  systemctl disable firewalld.service #禁止firewall开机启动

或者开启某端口 
firewall-cmd --permanent --add-port=50000/tcp用该命令查询firewall-cmd --permanent --query-port=50000/tcp如果是yes就是添加成功，如果是no就是没成功成功后重载防火墙firewall-cmd --reload

2.关闭SELINUX

vi /etc/selinux/config 
#SELINUX=enforcing #注释掉 
SELINUX=disabled #增加 
:wq! #保存退出 
setenforce 0 #使配置立即生效
