Centos7开放端口的操作

发布日期:2019/04/15 08:00:00

  问题描述:

  Hyper-V新建centos7虚拟机,无法通过CRT远程连接工具登陆

  环境:

  Windows 虚拟centos7 CRT远程连接工具

  作用::

  根据不同需求开放不同的端口,保证其安全性

  思路:

  1. 查看IP是否同一网段(虚拟机内网环境)

  2. 本地设备ping是否能ping通

  3. 查看端口

  步骤:

  1,使用ifconfig 命令查看虚拟机当前IP地址 是否在同一网段

  查看当前ip地址为192.168.3.27

Centos7开放端口

  使用ipconfig 命令查看当前设备IP地址,是否和虚拟机是在同一网段

  查看当前ip地址为192.168.3.6

Centos7开放端口

  2,使用ping命令,ping虚拟机ip地址,是否可以ping通

  可以ping通

Centos7开放端口

  3,查看centos7,端口号是否开放命令

  命令 firewall-cmd --list-ports

  查看当前开放端口为 22/tcp(做完测试结果,没有回滚快照,其实一个端口也没有开放)

  4,开放我们需要的端口

  命令 firewall-cmd --zone=public --add-port=80/tcp --permanent

  80/tcp 代表的是开放80端口,协议为tcp

  –permanent 表示永久生效,没有此参数重启后失效

Centos7开放端口

  5.重启防火墙

  命令 firewall-cmd --reload

Centos7开放端口

  6.使用CRT远程登陆测试

  输入主机地址 端口号 用户名 最后输入密码

  测试登陆成功

Centos7开放端口
