红帽 Linux9 版本网络管理及 VMware 虚拟机三种网络连接方式解析

此文章以红帽Linux9版本为例进行讲解。

红帽Linux9版本的网路管理非常全面,可在多处进行网路配置的更改,但须要注意的是,在9版本内,用户可在配置文件内进行网路配置的更改,但系统不会执行更改的命令,而在9之前的版本可执行。

VMware虚拟机上的三种网路联接形式

桥接模式:

通过虚拟集线器将主机上的网卡与虚拟网卡Vmnet0相联接,桥接模式下虚拟机的网卡都与虚拟交换机Vmnet0相联接,当虚拟机想要上网时linux系统与网络管理linux系统好用吗,需将虚拟机IP地址,子网网段,网段等配置与主机网卡相同。

NAT模式:

通过虚拟集线器将主机上的网卡与虚拟网卡Vmnet8相联接,NAT模式下虚拟机的DHCP服务器联接在Vmnet8虚拟交换机上,须要注意的是,虚拟网卡Vmnet8只是作为主机与虚拟机通讯的插口,虚拟机最终还是借助主机网卡进行联网。

Host-Only模式:

通过虚拟网卡Vmnet1与虚拟交换机Vmnet1相联接,进而实现虚拟机通讯,当虚拟机须要进行联网时,将主机联网的网卡共享给虚拟网卡Vmnet1,实现虚拟机联网。

NetworkManager的特征

NetworkManager是2004年RedHat启动的项目,借以才能让Linux用户更轻松地处理现代网路需求,能手动发觉网卡并配置ip地址。

NetworkManager的特征

NM能管理各类网路:

有线网卡、无线网卡

动态ip、静态ip

以太网、非以太网

化学网卡、虚拟网卡

工具齐全:

命令行、文本界面、图形界面、web

招纳天地:

管理各类网路,有线、无线、物理、虚拟

参数丰富:

多达200多项配置参数(包括ethtool参数)

一统江湖:

RedHat系、Suse系、Debian/Ubuntu系,均支持

大势所趋:

从红帽Linux9版本开始,只能通过NM管理网路

一、配置网路

网路插口是指网路中的计算机或网路设备与其他设备实现通信的进出口。这儿,主要是指计算机的网路插口即网卡设备。

从红帽Linux7版本开始引入了一种新的“一致网路设备命名”的形式为网路插口命名,该方法可以依据固件、设备拓扑、设备类型和位置信息分配固定的名子。网路插口的名称的前两个字符为网路类型符号。

网路类型符号:

en:表示以太网(Ethernet)

wl:表示无线局域网(wlan)

ww:表示无线广域网(wwan)

依据设备类型或位置选择符号:

o:表示外置(onboard)于显卡上的集成设备(即集成网卡)及索顿号;

s:表示是插在可以热插拔的插孔上的独立设备及索顿号;

x:表示基于MAC地址命名的设备;p——表示PCI插孔的数学位置及编号。

须要注意的是:

一个网路插口,可以有多个网路联接,但同一时间只能有一个网路联接处于活动状态。

一、修改配置文件(不推荐)

前提:

须要有network服务

步入配置文件

vim/etc/NetworkManager/system-connections/ens160.nmconnection

在配置文件内进行相应内容的编撰

二、使用IP命令配置临时生效的网路联接查看网卡在网路层的配置信息,加-s表示平添显示相关统计信息,如接收(RX)及传送(TX)的数据包数目等

二、网络测试命令一、ping命令

用于测试网路的连贯性

命令格式为:

ping[选项]

选项:

<span class="token parameter variable">-c</span> 数字:用于设定本命令发出的ICMP消息包的数量,若无此选项,则会无限次发送消息包直到 用户按【Ctrl+C】组合键才终止命令。
<span class="token parameter variable">-s</span> 字节数:设置ping命令发出的消息包的大小,默认发送的测试数据大小为56字节;自动添加8字节的ICMP协议头后,显示的是64字节;再添加20字节的IP协议头,则显示的为84字节。最大设置值为65507B。
<span class="token parameter variable">-i</span> 时间间隔:设定前后两次发送ICMP消息包之间的时间间隔,无此选项时,默认时间间隔为1 秒。为了保障本机和目标主机的安全,一般不要小于0.2秒。
<span class="token parameter variable">-t</span> :设置存活时间TTL<span class="token punctuation">(</span>Time To Live<span class="token punctuation">)</span>

<span class="token parameter variable">-b</span> :对沿途各主机节点同时显示IP地址和主机名。
<span class="token parameter variable">-l</span> 包长度:设置初始的数据包的大小。
