临时修改IP

ifconfig eno16777736 192.168.1.56

永久更改IP

/etc/sysconfig/network-scripts

找到网卡：

TYPE="Ethernet"
BOOTPROTO="dhcp"
DEFROUTE="yes"
PEERDNS="yes"
PEERROUTES="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_PEERDNS="yes"
IPV6_PEERROUTES="yes"
IPV6_FAILURE_FATAL="no"
NAME="eno16777736"
UUID="73fd9805-6fa3-46c0-9b40-139b6a4eb53b"
DEVICE="eno16777736"
ONBOOT="yes"

更改

BOOTPROTO="static"
//新增
IPADDR="192.168.1.57"
GATEWAY="192.168.1.255"
NETMASK="255.255.255.0"
DNS1="114.114.114.114"

重启

使用service network restart 命令，进行网卡重启
=/etc/init.d/network restart
下面是通用的重启
[email protected] ~]# systemctl restart network
systemctl restart mysqld

shutdown -r  now

动态获取ip

（前提是你的路由器已经开启了DHCP）

修改网卡配置文件 vi /etc/sysconfig/network-scripts/ifcfg-ens32    (最后一个为网卡名称)

动态获取IP地址需要修改两处地方即可

（1）bootproto=dhcp

（2）onboot=yes

配置静态IP地址

设置静态IP地址与动态iIP差不多，也是要修改网卡配置文件 vi /etc/sysconfig/network-scripts/ifcfg-ens32 (最后一个为网卡名称)

（1）bootproto=static

（2）onboot=yes

（3）在最后加上几行，IP地址、子网掩码、网关、dns服务器

IPADDR=192.168.1.160 ipaddr
NETMASK=255.255.255.0 netmask
GATEWAY=192.168.1.1 gateway
DNS1=119.29.29.29
DNS2=8.8.8.8
（4）重启网络服务

[[email protected] ~]# systemctl restart network

使用工具

然后使用nmtui命令调出修改窗口
选择 Edit a connectio，即编辑一个连接
选择右侧的Edit选项，编辑按钮，然后回车
将连接方式选为Manul，手动修改，然后在Address行修改ip地址

manul 
['meinul]
n. 手动；[脊椎] 兔狲；海底沙滩；（西藏，蒙古的）小野猫
