通过SSH连接本地linux虚拟机的过程记录

实验环境:
物理机 Windows 10 x64

物理网卡信息
IPv4地址:192.168.123.205
子网掩码:255.255.255.0
默认网关:192.168.123.1

虚拟机VMware Workstation14 Cent OS 6.7 x64

VMnet8信息:
IPv4地址:192.168.21.0
子网掩码:255.255.255.0
默认网关:192.168.21.2

一、修改VMware的网络设置

位置:工具栏->编辑->虚拟网络编辑器[管理员]

通过SSH连接本地linux虚拟机的过程记录

NAT设置->修改网关IP(G):将192.168.21.2修改为192.168.123.2

子网IP(I):将192.168.21.0修改为192.168.123.0

子网掩码(M):默认255.255.255.0

二、进入Linux修改网络配置

输入ip addr查看网卡信息

[root@localhost Desktop]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN 
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host 
 valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:3b:64:33 brd ff:ff:ff:ff:ff:ff
inet 192.168.31.31/24 brd 192.168.31.255 scope global eth0
inet6 fe80::20c:29ff:fe3b:6433/64 scope link 
 valid_lft forever preferred_lft forever
3: pan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN 
link/ether 1a:76:3b:91:89:e6 brd ff:ff:ff:ff:ff:ff

<BROADCAST,MULTICAST,UP,LOWER_UP> mtu所在段落前的网卡编号eth0即为之前设置的NAT网卡

调整网卡脚本,输入指令vi /etc/sysconfig/network-scripts/ifcfg-对应网卡编号
这里以eth0为例,输入vi /etc/sysconfig/network-scripts/ifcfg-eth0,输出vi编辑模式:

DEVICE="eth0"
BOOTPROTO="dhcp"
HWADDR="00:0C:29:3B:64:33"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="no"
TYPE="Ethernet"
UUID="d2818ab1-7ee1-44bf-b8b9-5bbecc6880f0"

静态IP模式:BOOTPROTO="static"

自启动:ONBOOT="yes"

静态IP信息:IPADDR=192.168.123.123 //选一个物理网卡的网段192.168.123.x中不冲突的IP

子网掩码:NETMASK=255.255.255.0

子网网关 GATEWAY=192.168.163.2

修改后如下后保存

DEVICE="eth0"
BOOTPROTO="static"
HWADDR="00:0C:29:3B:64:33"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="d2818ab1-7ee1-44bf-b8b9-5bbecc6880f0"
IPADDR=192.168.123.123
NETMASK=255.255.255.0
GATEWAY=192.168.123.2

三、重启网卡,检查Window网络适配器中NAT网卡的状态

重启指令:service network restart

VMnet8的属性之前自动获取方式的设置已经(自动)变成如下状态

通过SSH连接本地linux虚拟机的过程记录

注意:IP地址确认是否和物理网卡在同一网段内,且这个IP不要和之前的192.168.123.123搞混了,默认x.x.x.1就行了
子网掩码默认255.255.255.0,默认网关没有可以手动加上:192.168.123.2

四、进行SSH连接,附修复无法访问外部网络的方法

本地执行:ssh root@192.168.123.123提示输入密码后成功进入系统

测试修改静态IP后外部网络是否可用

[root@localhost ~]# ping baidu.com
ping: unknown host baidu.com

修改dns配置信息sudo vim /etc/resolv.conf,在dns配置末尾追加虚拟网卡网关地址:

search localdomain
nameserver 192.168.123.2

保存后稍等会片刻再次ping

[root@localhost ~]# ping baidu.com
PING baidu.com.localdomain (220.181.38.148) 56(84) bytes of data.
64 bytes from 220.181.38.148: icmp_seq=1 ttl=128 time=45.5 ms
64 bytes from 220.181.38.148: icmp_seq=2 ttl=128 time=44.9 ms
64 bytes from 220.181.38.148: icmp_seq=3 ttl=128 time=45.4 ms
64 bytes from 220.181.38.148: icmp_seq=4 ttl=128 time=45.1 ms
64 bytes from 220.181.38.148: icmp_seq=5 ttl=128 time=45.2 ms
64 bytes from 220.181.38.148: icmp_seq=6 ttl=128 time=45.0 ms

如果重启网卡或者系统会让DHCP自动获取dns导致之前修改的dns配置失效,所以需要在网卡配置中vi /etc/sysconfig/network-scripts/ifcfg-eth0
