#1、开启防火墙 
    systemctl start firewalld

#2、开放指定端口
      firewall-cmd --zone=public --add-port=1935/tcp --permanent
 #命令含义：
--zone #作用域
--add-port=1935/tcp  #添加端口，格式为：端口/通讯协议
--permanent  #永久生效，没有此参数重启后失效

#3、重启防火墙
      firewall-cmd --reload
#4、查看端口号
netstat -ntlp   //查看当前所有tcp端口·
netstat -ntulp |grep 1935   //查看所有1935端口使用情况
