linux连不上网的解决方法

今天小编分享的是关于linux连不上网的解决方法，可能大家对linux并不陌生，或者从来没有了解过linux。但是不用担心，今天小编会以最简单的描述来讲linux连不上网的解决方法。

Today, Xiaobian shares the solution to the problem that Linux can't connect to the Internet. Maybe everyone is not new to Linux or has never known about Linux. But don't worry. Today, Xiaobian will use the simplest description to describe the solution of Linux not connecting to the Internet.

一、检查当前环境配置的ip信息

1、 Check the IP information of the current environment configuration

二、检查网络配置是否正确

2、 Check if the network configuration is correct

[root@hadoop/]# cat /etc/sysconfig/network-scripts/ifcfg-eth0

[root@hadoop/]# cat /etc/sysconfig/network-scripts/ifcfg-eth0

DECIVE=eth0 //指向的网络配置文件

Deceve = eth0 / / the network configuration file pointed to

IPADDR=192.168.1.226 //IP地址

IPADDR = 192.168.1.226 / / IP address

GATEWAY=192.168.1.1 //网关地址

Gateway = 192.168.1.1 / / gateway address

DNS1=8.8.8.8 //DNS解析服务器NETMASK=255.255.255.0 //子网掩码

Dns1 = 8.8.8.8 / / DNS resolution server netmask = 255.255.255.0 / / subnet mask

三、ping一下设置的网关是否能够ping通，如果网关无法连通，则需要修改 /etc/sysconfig/network-scripts/ifcfg-eth0文件下的网关地址

3、 Ping whether the set gateway can be pinged. If the gateway cannot be connected, you need to modify the gateway address in the / etc / sysconfig / network scripts / ifcfg-eth0 file

[root@hadoop/]# ping 192.168.1.1

[root@hadoop/]# ping 192.168.1.1

四、检查DNS服务器是否正确，使用命令

4、 Check whether the DNS server is correct, use the command

[root@hadoop etc]# cat resolv.conf

[root@hadoop etc]# cat resolv.conf

五、ping配置的DNS服务解析地址，看是否能够ping通，如果无法连通，则需要修改，但必须保证是正常的能使用的DNS地址

5、 Ping the configured DNS service to resolve the address to see if it can ping through. If it can't connect, it needs to be modified, but it must be a normal DNS address that can be used

六、只有上述配置都无误后，就可以连通外网资源，再进行测试，是否能ping通外网资源

6、 After the above configurations are correct, you can connect the external network resources, and then test whether you can ping the external network resources

[root@hadoop etc]# ping www.baidu.com

[root@hadoop etc]# ping www.baidu.com
