今天部署了大运维平台,访问telnet不通

1、查看哪些端口被打开了:netstat -anp

2、确保端口未在使用

netstat -na | grep :9006
ss -na | grep :9006

3、启用端口

安装systemctl:yum install iptables-services
设置开机启动
systemctl enable iptables.service
因为centos7默认的防火墙是firewalld防火墙,不是使用iptables,因此需要先关闭firewalld服务,或者干脆使用默认的firewalld防火墙。
关闭firewalld:
systemctl stop firewalld  
systemctl mask firewalld
开启9006端口
iptables -A INPUT -p tcp --dport 9006 -j ACCEPT
保存规则 service iptables save 开启服务 systemctl restart iptables.service

 firewall-cmd --zone=public --add-port=9006/tcp --permanent
