⑴ Linux中/etc/named.conf配置文件如何设置

1、首先打开一台linux虚拟机。

⑵ linux怎样通过命令修改ip地址

你好，不知你系统版本就告诉你最主流最新的RHEL 7/CentOS7 的IP修改办法，根据《linux 就该这么学》上面的方法：

在红帽RHEL6系统中网卡配置文件的前缀为"eth"，第1块即为"eth0"，第2块即为"eth1"并依此类推……
而在红帽RHEL7系统中网卡配置文件的前缀则为"ifcfg-eno"，例如"ifcfg-eno16777736"。
第1步:首先我们要切换到"/etc/sysconfig/network-scripts"目录中（该目录存放着网卡的配置文件）。

第2步:使用vim命令修改文件"ifcfg-eno16777736"。
第3步:逐项写入配置参数，并保存退出。
网卡类型:TYPE=Ethernet
地址分配模式:BOOTPROTO=static
网卡名称:NAME=eno16777736
是否启动:ONBOOT=yes
IP地址:IPADDR=192.168.10.10
子网掩码:NETMASK=255.255.255.0
网关地址:GATEWAY=192.168.10.1
DNS地址:DNS1=192.168.10.1

第4步:重新启动网卡命令:"systemctl restart network"。
第5步:通过ping命令测试网卡信息是否生效。
上面的操作需要借助vim编辑器，如果你对vim编辑器和linux下ip地址的修改有疑问可以看看我上面看的那本教材，此教材是多名运维高手编写的，可以快速让你上手linux操作系统！

⑷ 虚拟机装的linux centos7怎么设置网络

先来了解下虚拟机下的3中网络模式：

Bridged（桥接最适合生产环境）

特别提醒：

在红帽RHEL6系统中网卡配置文件的前缀为"eth"，第1块即为"eth0"，第2块即为"eth1"并依此类推，但在红帽RHEL7系统中的网卡配置文件前缀则以"ifcfg-eno"开始的。

⑸ 如何为CentOS 7配置静态IP地址的两种方法

两种方法可以更改：

一、netconfig命令

输入netconfig后将会出现下图所示，单击yes按钮。

进行相关配置后ok退出。

二、编辑网卡配置文件

1、vi /etc/sysconfig/network-scripts/ifcfg-eth0

2、配置完以后重启动服务，ip地址就配置好了。

注意：此方法配置的ip地址后计算机从新启动仍然有效。
