Question

我在windows上的virtualbox中使用centos7.并且vagrant发了它,用http或https得到了ping错误.还卷曲.有人可以帮我解决问题并让它发挥作用.

[root@localhost ~]# ping google.com

`

的resolv.conf

[root@localhost ~]# cat /etc/resolv.conf 
nameserver 10.0.2.3
nameserver 8.8.8.8
nameserver 8.8.4.4
search localhost

`

使用ifconfig

[root@localhost ~]# ifconfig 
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.0.2.15  netmask 255.255.255.0  broadcast 10.0.2.255

Answer 1

首先确保在虚拟框设置中启用了网络适配器.

您用于连接到Internet的网络接口可能无法激活.

1. 要检查这一点,请使用" sudo nmcli d "命令.

2. 如果断开连接,请使用" sudo nmtui " - >编辑连接,选择网络接口并选择"自动连接"选项(按空格键),然后选择确定.

3. "sudo reboot now"登录后,请"ping www.google.com".

你应该能够立即连接.

Answer 2

ping与HTTP或HTTPS无关:

Ping将使用ICMP协议,它属于TCP/IP

Ping通过向目标主机发送Internet控制消息协议(ICMP)回送请求数据包并等待ICMP响应来进行操作.

实际上ping的工作水平远低于HTTP或HTTPS,并且只接受主机名,而不是URL.
