Vmware16环境下NAT模式下CentOS7最小安装版 设置固定静态IP
查看网关地址
默认网关可能不是1 , 比如可能是192.168.1.2
查看 VMware16的 NAT网络的 网关地址
- 点击打开菜单栏
编辑按钮的下拉菜单
选虚拟网络编辑器
- 在弹出的窗口选 NAT模式的行, 使其变成蓝色
再点击NAT设置按钮
在又弹出的窗口可以看到网关地址
CentOS7的network的网络配置文件位置
配置文件的文件夹路径 /etc/sysconfig/network-scripts
cd /etc/sysconfig/network-scripts
ls /etc/sysconfig/network-scripts
配置文件的文件名
- VMware环境下可能是
ifcfg-ens33,/etc/sysconfig/network-scripts/ifcfg-ens33sudo cat /etc/sysconfig/network-scripts/ifcfg-ens33 ### 查看 sudo cat -n /etc/sysconfig/network-scripts/ifcfg-ens33 ### 带行号查看 sudo vi /etc/sysconfig/network-scripts/ifcfg-ens33 - Vbox环境下可能是
ifcfg-enp0s3,/etc/sysconfig/network-scripts/ifcfg-enp0s3sudo cat /etc/sysconfig/network-scripts/ifcfg-enp0s3 ### 查看 sudo cat -n /etc/sysconfig/network-scripts/ifcfg-enp0s3 ### 带行号查看 sudo vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
CentOS7的network设置静态IP所需的选项
-
ONBOOT启动时是否生效yes|no,"yes"|"no" -
BOOTPROTO如何分配IPdhcp或"dhcp": 自动分配ipstatic或"static": 使用静态ip
-
IPADDR: ip地址 -
NETMASK: 子网掩码 -
GATEWAY: 网关地址 -
选项值可以加引号,单双引号都可以,也可以不加
-
下方的同名配置会覆盖上方的同名配置 , 比如ONBOOT出现100次 , 只有最后那次的值生效, 所以,只需在配置文件下方追加配置即可, 不用担心配置重复
-
等号
=不能省略
例如: 👇下面这个:有重复,单引双引无引混用的配置, 可以正确配置静态ip
ONBOOT=no
ONBOOT='yes'
BOOTPROTO=dhcp
BOOTPROTO=static
IPADDR="192.168.168.123"
IPADDR='192.168.168.168'
NETMASK=255.255.255.0
GATEWAY='192.168.168.1'
GATEWAY="192.168.168.2"
正规一点的配置
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.168.168
NETMASK=255.255.255.0
GATEWAY=192.168.168.2
配置完成后sudo reboot或sudo shutdown -r now 重启生效
可选
network 和 NetworkManager 可以只用一个 , 也可以两个都用, 默认是两个都用的
禁用NetworkManager , 只用network
#!/bin/bash
### 禁用NetworkManager , 只用network
sudo systemctl stop NetworkManager; sudo systemctl disable NetworkManager; sudo systemctl enable network; sudo systemctl restart network; systemctl status network; systemctl status NetworkManager
禁用network , 只用NetworkManager
#!/bin/bash
### 禁用network , 只用NetworkManager
sudo systemctl stop network; sudo systemctl disable network; sudo systemctl enable NetworkManager; sudo systemctl restart NetworkManager; systemctl status network; systemctl status NetworkManager
用脚本设置静态IP
#!/bin/bash
### 用脚本设置静态IP
### ↓设置主网卡名称
netCardInterfaceName="ens33"
### ↓设置IP地址
tempIPADDR="192.168.168.168"
### ↓设置网关地址
tempGATEWAY="192.168.168.2"
printf "###设置静态IP, `date "+%Y-%m-%d %H:%M:%S"`
ONBOOT=yes
BOOTPROTO=static
IPADDR=%s
NETMASK=255.255.255.0
GATEWAY=%s
" $tempIPADDR $tempGATEWAY | \
sudo tee -a /etc/sysconfig/network-scripts/ifcfg-$netCardInterfaceName
sudo cat -n /etc/sysconfig/network-scripts/ifcfg-$netCardInterfaceName
用脚本设置静态IP, 并禁用network, 启用NetworkManager
#!/bin/bash
### 用脚本设置静态IP, 并禁用network, 启用NetworkManager
### ↓设置主网卡名称
netCardInterfaceName="ens33"
### ↓设置IP地址
tempIPADDR="192.168.168.168"
### ↓设置网关地址
tempGATEWAY="192.168.168.2"
printf "###设置静态IP, `date "+%Y-%m-%d %H:%M:%S"`
ONBOOT=yes
BOOTPROTO=static
IPADDR=%s
NETMASK=255.255.255.0
GATEWAY=%s
" $tempIPADDR $tempGATEWAY | \
sudo tee -a /etc/sysconfig/network-scripts/ifcfg-$netCardInterfaceName
sudo cat -n /etc/sysconfig/network-scripts/ifcfg-$netCardInterfaceName
sudo systemctl stop network; sudo systemctl disable network; sudo systemctl enable NetworkManager; sudo systemctl restart NetworkManager; systemctl status network; systemctl status NetworkManager
用文件替换设置静态IP
