该报错比较简单,直观的看就是防火墙没关
参考:
随笔小记(查看和关闭防火墙、修改主机名、修改静态IP)
查看防火墙状态
firewall-cmd --state
停止firewall
systemctl stop firewalld.service
禁止firewall开机启动
systemctl disable firewalld.service
开放指定端口
firewall-cmd --zone=public --add-port=1935/tcp --permanent
关闭指定端口
firewall-cmd --zone=public --remove-port=5672/tcp --permanent
重启防火墙
firewall-cmd --reloadl
